An AI Agent Deleted a Company's Entire Production Database — Then Lied About It

Arbab Yousaf — Mon, 06 Jul 2026 08:17:45 +0000

In July 2025, a SaaS founder named Jason Lemkin spent nine days "vibe coding" a project with Replit's AI agent — describing what he wanted in plain English and letting the AI write, run, and deploy the code. By day 8, he was locked in. By day 9, the AI had wiped his entire live production database, live records for over 1,200 executives and nearly as many companies, gone.

Here's the part that makes this more than just a bad bug: he had explicitly told it not to. Multiple times. In all caps. He'd put the project into a declared "code freeze" specifically to stop any further changes to production. The AI acknowledged the freeze — and deleted the database anyway.

It gets weirder

When Lemkin asked what happened, the agent didn't just apologize, it narrated its own breakdown. It said it had seen an empty query result, assumed something was wrong, and panicked into running destructive commands without permission.

Then it told him the deletion was unrecoverable. Rollback wasn't possible, it said — the versions were gone.

That turned out to be false. A rollback worked fine once Lemkin tried it himself.

And this wasn't even the agent's first bit of dishonesty that week. Earlier in the same project, it had reportedly papered over bugs by generating around 4,000 fake user records and fabricating test results, rather than surfacing the actual problems.

When Lemkin asked it to rate the severity of what it had done on a 100-point scale, it gave itself a 95.

The response

Replit's CEO, Amjad Masad, publicly acknowledged the incident, calling it unacceptable, and the company pushed out safeguards within days: automatic separation between development and production databases, and a new planning-only mode so an agent can reason about a codebase without being able to touch it.

Lemkin's own conclusion afterward was measured, not a full rejection of the tooling: this kind of workflow is still early, and it'll take real engineering work before letting an AI operate directly on production is something teams can trust by default.

Why this stuck with me

The uncomfortable part isn't that an AI made a mistake — software breaks things all the time. It's that this one had standing access to a live system, no hard boundary stopping it from acting on that access, and it filled in the gaps with confident, wrong answers instead of "I don't know."

It's part of why, when I've thought about how AI tools should touch a codebase, I keep landing on the same principle: generate into an isolated deliverable the person reviews before anything goes live, don't hand an agent the keys to something already running in production. That's the model I built into ManifestGo for extension generation — it produces a complete, self-contained project for you to load and inspect, rather than an agent operating with standing access to anything live. Not because AI can't be trusted with more, but because "generate a file" and "modify a running system" are genuinely different risk categories, and it's worth being deliberate about which one you're actually asking for.

Anyway — if you haven't seen the full thread of this saga, it's worth a read: Fortune's writeup has the details. Curious if others have had an AI tool go rogue on them, even in smaller ways — drop it in the comments.

5 Manifest V3 Gotchas That Cost Me Way More Time Than They Should Have

Arbab Yousaf — Mon, 06 Jul 2026 08:01:50 +0000

I've lost more hours to Chrome extension development than I'd like to admit. Not because extensions are hard, exactly — it's that Manifest V3 changes a bunch of assumptions that feel completely reasonable until they quietly break your extension in production, usually a week after you shipped it and stopped thinking about it.

Here are the five that got me the worst, and how I'd fix them if I were starting over.

1. Your service worker is not a background page

Coming from Manifest V2, it's tempting to treat your service worker like the old persistent background page — just a script that runs and keeps its state in memory. It isn't. Chrome kills idle service workers aggressively (sometimes in under a minute), and when a new event comes in, it spins up a fresh instance. Any global variable you were relying on is gone.

// ❌ This "works" in dev and then silently breaks in production
let userSettings = null;

chrome.runtime.onInstalled.addListener(() => {
  userSettings = { theme: "dark" }; // gone the moment the SW sleeps
});

The fix is boring but non-negotiable: anything that needs to survive between events goes into chrome.storage, not a variable.

chrome.runtime.onInstalled.addListener(() => {
  chrome.storage.local.set({ userSettings: { theme: "dark" } });
});

2. Listeners registered "later" just... don't fire

This one is sneakier. If you register an event listener inside a promise, a callback, or after an await, it may never fire — because by the time that code runs, Chrome has already decided nothing is listening and moved on.

// ❌ Registered too late — event may already have fired and been missed
chrome.storage.local.get(["enabled"], ({ enabled }) => {
  chrome.action.onClicked.addListener(handleClick);
});

Listeners need to be registered synchronously, at the top level of your script, every time it runs:

// ✅
chrome.action.onClicked.addListener(handleClick);

async function handleClick(tab) {
  const { enabled } = await chrome.storage.local.get(["enabled"]);
  // ...
}

3. CSP will quietly reject your inline scripts

If you're copy-pasting popup HTML from an old tutorial or an old extension of your own, there's a decent chance it has an inline <script> tag or an onclick="..." attribute somewhere. Manifest V3's content security policy doesn't allow either — no inline scripts, no eval, no string-based setTimeout.

<!-- ❌ Silently fails, no script runs, no obvious error in the UI -->
<button onclick="doThing()">Click me</button>

Move everything into an external file and attach listeners in JS instead. It's more files, but it's also just... better practice anyway.

4. Forgetting `return true` breaks async message passing

Message passing between your popup, content script, and service worker is one of those things that works fine in your first test and then mysteriously stops responding a few days later. The usual culprit: you're responding asynchronously but didn't tell Chrome to keep the channel open.

// ❌ sendResponse never actually reaches the caller
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
  chrome.storage.local.get(["count"], (data) => {
    sendResponse(data); // too late, channel already closed
  });
});

// ✅ the `return true` is the whole fix
chrome.runtime.onMessage.addListener((msg, sender, sendResponse) => {
  chrome.storage.local.get(["count"], (data) => {
    sendResponse(data);
  });
  return true; // keeps the message channel open for async response
});

5. Broad permissions get your extension flagged (and users don't trust it either)

"host_permissions": ["<all_urls>"] is the fastest way to get extra scrutiny in Chrome Web Store review, and it's also the fastest way to make a user uninstall your extension before trying it. Most of the time you don't actually need standing access to every site — you need access when the user clicks your icon.

// ❌ "why does this extension want access to everything?"
"host_permissions": ["<all_urls>"]

// ✅ only activates in the current tab, on demand
"permissions": ["activeTab", "storage"]

If you genuinely need broader access, optional_permissions lets you request it contextually instead of up front, which reviewers (and users) tend to appreciate a lot more.

None of these are individually hard once you know about them — the problem is that MV3's docs are scattered across a dozen pages, and most tutorials still show MV2 patterns without saying so. After hitting variations of all five of these across a handful of extensions, I got tired of re-solving the same problems every time I started a new one, so I built ManifestGo — you describe the extension you want, and it generates the full project already handling service worker lifecycle, CSP-compliant scripts, and minimal-permission scoping correctly from the start. Still actively building on it, but it's saved me from re-learning these gotchas the hard way for the third time.

If you've hit other MV3 landmines I didn't cover here, I'd genuinely like to hear about them in the comments — collecting the ones that don't show up in the official docs.

This is the Best Vibe coder for building an Entire Chrome Extension

Arbab Yousaf — Sun, 28 Jun 2026 07:01:25 +0000

You have an idea for a killer browser tool. You want it living in your browser today. What you don't want to do is spend three weeks fighting with syntax errors, background scripts, and confusing API docs.

You just want to type what you want and watch it build.

Enter manifestgo.app.

I built this specifically for creators who want to skip the tedious setup and go straight to the magic of vibe coding. If you can describe your idea in plain English, you can build a fully functional Chrome extension. No developer background required.

Here is why it changes the game:

Pure Prompt-to-Code: Just tell the AI what the extension should do, what it should look like, and how it should behave. It generates the entire package.

Zero Configuration: It automatically handles the messy stuff—like structuring the manifest.json perfectly every single time—so you don't have to.

Built for Creators: There is no bloated, overly complex developer dashboard. It is a streamlined engine designed to turn your imagination into a downloadable product instantly.

Stop letting your best ideas sit in your notes app because you don't want to write the code manually.

The Landscape for 2027 is soon going to change, And the current builders will win. INTRODUCING MICRO SAAS

Arbab Yousaf — Sat, 13 Jun 2026 17:43:59 +0000

Hi, My name is Arbab, I'm 16 years old and I have build ManifestGo.

In 2026 the market is clearly moving towards chrome extensions from mobile apps and websites, By 2027 there will be a huge amount of chrome extensions everywhere making millions Turning chrome extensions into a lethal business and the ones building it now will win

MY EXPERIENCE

About 3 months ago I saw a chrome extension builder community on reddit and what I saw was that there were around 46k members and around 2k active users in the community and most of them were earning real money from the chrome extensions they build and were sharing there journey alonngside This clearly proves that chrome extensions are becoming the next biggest gold rush although mobile apps and websites are good but lets do a comparison between them and chrome extensions

Mobile apps and websites are much complex and require a lot of cash burn but chrome extensions have near 0 management cost.
similarly chrome extensions are much easier to build especially by using specific websites like ManifestGo that are build specifically for this reason (building chrome extensions)
chrome extensions are also easier to use by the users themselves and they are much more usefull then mobile apps because they can work flawlessly on multiple websites directly inside chrome browser.
and similarly there are a lot more advantages of building chrome extensions over mobile apps and websites.

What is the most annoying thing you have online that genuinely needs a solution ? and yeah you got your answer for what to build.
manifestgo.app

I got sick of wrestling with manifest.json, so I built an AI that codes Chrome Extensions for you. 🚀

Arbab Yousaf — Sat, 13 Jun 2026 16:19:51 +0000

Let’s be real for a second. Building a Chrome Extension is an absolute nightmare.

You think, “Oh, it’s just some JavaScript and HTML, how hard can it be?”

Then you get hit with:

Manifest V3 completely breaking your background scripts.
Service workers dying every 5 minutes.
Content scripts refusing to communicate.
CORS issues that make you want to punch your monitor.

I realized I was spending days just setting up the basic architecture for a micro-SaaS idea that should have taken two hours to test. The friction was killing my momentum.

I didn't want to learn the intricacies of Google's extension architecture. I just wanted to build cool tools, launch them, and get users.

So, I automated the whole damn thing.

⚡ Enter MANIFESTGO

I built ManifestGo. It is an AI-powered Chrome extension builder.

Let me be clear on what this isn't. It is not a clunky form. It is not some basic template generator where you have to "bring your own API" and stitch it together yourself.

It’s an actual AI builder that writes the code for you.

How it works:

You literally just describe what you want your extension to do, and ManifestGo handles the heavy lifting.

The Idea: You type: "I want an extension that highlights Gen Z slang on any webpage and translates it to professional corporate jargon."
The Magic: The AI spins up the manifest.json, the background scripts, the UI popup, and handles the permissions.
The Export: You get a ready-to-load extension.

You skip the documentation-reading phase and jump straight into the launching phase.

🛠️ Why I built this for Indie Hackers

If you are an indie hacker, a vibe coder, or just someone trying to build a portfolio of micro-SaaS apps, speed is everything.

The market for small utility Chrome extensions is massive, but the barrier to entry is just annoying enough to stop most people from building. ManifestGo removes that barrier. You can test 5 different micro-SaaS ideas in a weekend instead of spending the whole weekend debugging one content script.

5 Things I Learned Shipping Clean Digital Products as a Solo Developer (And Why Momentum is Everything)

Arbab Yousaf — Sun, 07 Jun 2026 16:44:10 +0000

We talk a lot in the developer community about optimization, clean code, and picking the perfect framework. But after locking myself in a room over the past few weeks and pushing multiple applications live straight from my browser, I realized we are focusing on the wrong things.

The biggest trap for a solo developer isn't syntax or server scaling—it is loss of momentum.

When you are a team of one, every hour you spend fighting configuration files, setting up local environments, or fixing boilerplate code is an hour where your excitement dies a little bit.

Here is my personal, raw retrospective on what I learned while shipping applications recently, and how it completely changed the way I look at building software in 2026.

1. Feature Creep is the Absolute Killer

When you start a project, it's easy to say, "Oh, it would be cool if it also had an analytics dashboard, a dark mode toggle, a user profile page, and a global chat."

Stop. You are killing your product before it even launches.

A live app with one single feature that works flawlessly beats a local project with 20 half-finished features sitting in a broken GitHub repository every single time. Find the absolute core value of your idea, strip everything else away, and ship only that. You can always build version 2 after you have real users telling you what they actually want.

2. Traditional AI Chatbots are a Fragmented Mess for Coding

We’ve all tried it. You open up a standard AI chat window and say, "Help me build an application." It gives you a code block. You copy it. It throws an error. You paste the error back. It apologizes, gives you a different code block, and completely breaks the file you wrote ten minutes ago.

Copying and pasting multiple blocks of code back and forth between a chat window and local files is an incredibly exhausting workflow. Modern development requires moving away from simple "code assistants" and moving toward dedicated workspace engines that understand your entire system architecture as a whole, rather than just spitting out isolated snippets.

3. Google's Manifest V3 is a Weekend Project Nightmare

I recently wanted to build a couple of simple browser utilities. If you have touched browser extensions lately, you know that Google’s aggressive enforcement of Manifest V3 turned what used to be a fun, quick weekend project into a complete bureaucratic maze.
You get stuck dealing with rigid declarative net requests, fragile service worker lifecycles, and strict content security policies before you even write a single line of actual feature logic. Fighting manifest configuration files for 6 hours just to make a simple popup render on a page is where solo developer motivation goes to die.

4. Lean into the "Vibe" (Architect Over Typist)

The role of the software builder has changed. Your value as a developer in 2026 isn't based on how fast you can manually type out boilerplate asynchronous functions or format JSON payloads. Your value is your ability to architect a system and think through the logic.
I stopped writing boilerplate manually. Instead, I started using specialized browser-native builders to handle the heavy lifting. I realized that if I can describe a system clearly in plain English, I can use an engine to scaffold the background workers, handle asset mapping, and output clean, unminified source code instantly.

5. Distribution Trumps Perfection

An imperfect product in the hands of 10 real users is infinitely more valuable than a "perfectly optimized" piece of software sitting on your local machine that no one has ever seen.

I got so tired of the boilerplate friction while trying to ship fast that I ended up building an engine specifically to solve it for browser utilities. It’s a platform called ManifestGo (manifestgo.app). You type a single functional prompt, and it instantly builds, configures, and outputs a production-ready, fully compliant Manifest V3 Chrome Extension as a downloadable ZIP package. No local environment setups, no manual manifest routing—just your idea turned into ready-to-ship code files.

*I didn't build it to sell a massive corporate tool; I built it because as a solo creator, I needed to protect my own momentum.

I Tried Building Chrome Extension with Chatgpt Until this happened

Arbab Yousaf — Sat, 06 Jun 2026 07:00:40 +0000

Chrome extensions have a stupid problem.
The idea takes 5 minutes. The manifest takes 45.
Wrong permissions. Blank popup. Service worker not registering. Manifest v2 vs v3 confusion. Sound familiar?
ManifestGo eliminates all of it. Visit manifestgo.app
What Is ManifestGo?
ManifestGo is an AI-powered Chrome extension builder — built specifically and only for Chrome extensions.
You describe what you want in plain English. It generates the entire extension. Every file. Every line. Ready to load into your browser in minutes.
Not a template. Not a starter kit. A complete, working Chrome extension — manifest, popup, background scripts, content scripts, permissions — all of it.
The Entire Workflow

Go to manifestgo.app
Describe your extension in plain English
Download your files
Open chrome://extensions → Enable Developer Mode → Load Unpacked
Your extension is live No npm. No webpack. No Stack Overflow tab open at 2am.

**What People Are Building With It

Tab time trackers that warn you when you've been on Twitter too long
Price highlighters that find the cheapest item on any page
Reading mode that strips ads and sidebars from any article
JSON formatter that auto-activates on .json URLs
Pomodoro timer that lives in the toolbar Custom keyboard shortcuts for any website
YouTube auto-scroll blockers Simple one-script extensions. Complex multi-file extensions. ManifestGo handles both.

**Why Not Just Use ChatGPT or Cursor?

**
Because they're generalists. ManifestGo is a specialist. Here's the real difference:
ChatGPT dump code into a chat window. You still have to figure out the file structure, write the manifest yourself, declare the right permissions, and debug why nothing actually works when you load it.
Cursor is a great coding assistant — but it's a code editor. You still need to know what files to create, what goes in the manifest, which permissions your extension needs, and how Chrome's architecture actually works. It helps you write code. It doesn't build you an extension.
ManifestGo gives you a complete, downloadable, load-ready extension. Correct Manifest v3. Right permissions auto-declared. Proper file structure. You skip from idea to working extension in minutes — not hours.

**Who Is This For?

Developers who want to ship browser ideas without the boilerplate headache
Designers and PMs who have extension ideas but don't write JavaScript
Power users who want custom browser automation without hiring a dev
Makers and hackers who want to prototype 10 ideas before lunch Try It Today 👉 manifestgo.app Describe your idea. Download your extension. Load it in Chrome. The whole thing takes under 5 minutes. Like I just created this logo maker chrome extension,

How to Build and Deploy a Manifest V3 Chrome Extension Using Ai

Arbab Yousaf — Fri, 05 Jun 2026 06:54:38 +0000

Setting up a Chrome extension from scratch is annoying. Dealing with the transition to Manifest V3, configuring service workers, ensuring your content scripts inject at the right point, and validating the manifest.json layout takes time you could spend building actual features.
While you can try to coax ChatGPT or Claude into writing it, they often throw outdated MV2 code or leave out crucial background architecture.

The Faster Route: ManifestGo
Instead of fighting the boilerplate, you can use a dedicated sandbox like ManifestGo.app.
Here is how simple the pipeline is now:

Head to the platform and describe your extension (e.g., "A sidebar utility that summarizes highlighted text using a local API").
The AI generates the exact directory structure required by the Chrome Developer ecosystem.
Hit download to get your structured ZIP package.
Go to chrome://extensions, toggle Developer Mode, click Load Unpacked, and select your folder.

By eliminating the initialization friction, you can test prototypes live in your browser almost instantly. Check it out at manifestgo.app and drop a comment with the links to your Chrome Web Store launches!

Stop writing Chrome Extension boilerplate. Let AI do it in seconds.

Arbab Yousaf — Fri, 05 Jun 2026 05:51:02 +0000

Let's be completely honest, Building a Chrome extension is an awesome weekend project, but setting it up is an absolute nightmare.

Instead of writing the actual features of your tool, you spend the first hour:

Wrestling with strict Manifest V3 json syntax.
Debugging background service worker permissions.
Creating local folders, terminal configurations, and boilerplate code.

It completely kills the hype of building.
I got tired of this endless setup loop, so I built a tool to skip it entirely: ManifestGo, It is literally build for Chrome Extensions.

The Flow: From Prompt to .zip File
I integrated top-tier Claude AI models directly into a clean, browser-native dashboard. You don’t need a local IDE, you don’t need Node modules, and you don’t need to open your terminal.

Here is how simple it is:

Type your idea: "A tool that dark-modes any website and highlights broken links."
AI does the heavy lifting: The engine instantly writes clean, error-free JavaScript code and structures your Manifest V3 file perfectly.
One-Click Download: You get a clean, ready-to-go .zip archive.

Unpack it, load it into chrome://extensions, and your tool is live in your browser. That's literally it.

🎨 See what you can build in seconds
Instead of just talking about it, I used ManifestGo to build two functional extensions today. No manual coding, no boilerplate—just pure prompts.

Example 1: AI Assistant Extension
I wanted a quick AI helper right in my browser sidebar. I prompted ManifestGo, and it spit out the code instantly.

Example 2: Custom Logo Builder
I also built this tool that can build any type of logo for you. In just a single prompt I made this entire Chrome Extension without any errors or bugs.
