I Used Every AI Coding Assistant I Could Find for a Month. Here's What I Actually Pay For Now

Note: this is the fourth post in an ongoing series where our small editorial team tests AI tools in real workflows and writes down what we find. No affiliate links. No "sponsored by" disclaimers to hide. We pay for the tools we review, including this month's experiment, which cost us about $190 in subscriptions and a fair amount of patience.

The setup

I spent most of August and September doing the same two jobs across eight AI coding tools: building a small internal dashboard (React + a Node API) and maintaining an older Python service at work. Same tasks, same files, same me. The tools were GitHub Copilot, Cursor, Codeium, Tabnine, Replit AI, v0, Bolt, and Lovable.

Why those eight? Because those are the ones people actually argue about in our developer group chats — and the ones a colleague keeps asking me to "just try already." I also wanted to answer one question that none of the marketing pages answer: what happens after the first week, when the novelty wears off and the tool has to earn its place in a daily workflow?

Quick background so you know where I'm coming from: I'm a working developer, not a journalist. Ten years mostly backend, some frontend when I have to. I'm skeptical of anything that promises to write my code for me, and I've been burned before by autocomplete that produces confident nonsense.

The short version

If you only take one thing from this: Copilot is still the safest default, Cursor is the most capable if you'll actually use its chat properly, and the no-code app builders (Bolt, Lovable, v0) are not for me — but they're genuinely impressive for people who don't live in an IDE.

Everything below is the longer version with the boring details, including the stuff that surprised me.

GitHub Copilot: the boring, reliable choice

I started with Copilot because it's what most of my team already had. The completions are fast and mostly invisible — which is the point. It suggests the next line or two, you tab, you move on. In the Python service, it was genuinely good at finishing the boilerplate I was typing: error handlers, test stubs, the repetitive parts of migrations.

The autocomplete quality has gotten noticeably better in the last year, but the real change is the chat. I used Copilot Chat for the dashboard's data-fetching layer and it did a solid job explaining legacy code and suggesting refactors. It wasn't magical. It was like having a decent pair programmer who occasionally needs you to rephrase the question.

The catch: it's still autocomplete-first. For big architectural questions — "should I split this service here or there" — it gives you an answer but doesn't push back. It agrees with whatever direction you're leaning, which is not always what you need.

Cursor: the one I kept paying for

Here's the thing about Cursor that its fans don't explain well: the magic isn't the autocomplete, it's the agent mode where you can point it at a file, describe a change, and watch it edit the file with a diff you can review. I used this for the dashboard's form validation and it worked — not perfectly, but well enough that I felt like I was reviewing a junior dev's PR instead of writing everything myself.

It's also the only tool where multi-file edits felt safe. Copilot suggests, Cursor executes, and execution is where the real time savings are.

Downsides are real: it's a fork of VS Code with its own config quirks, and the good models behind it cost extra. On the free tier you'll run out of the good stuff fast. I paid for a month of Pro to test properly and honestly, for the way I work, it was the only subscription in this experiment I didn't feel guilty about renewing.

Codeium: the free one that's actually free

Codeium is the tool I most wanted to fail, because its pitch sounds too good — "free forever, unlimited completions." But for autocomplete specifically, it was shockingly close to Copilot for my Python work. Not identical, but close enough that I had to check which one I was using during a blind test with a colleague.

Where it falls short is the chat and deeper IDE integration. The suggestions are great; the conversational features feel a step behind. If you're on a budget or your company won't pay for tools, Codeium is a completely reasonable daily driver. My notes literally say "why would I pay for Copilot if this exists?" — and then I remembered: Copilot's chat is better, and Codeium's enterprise story is murkier.

Tabnine: the privacy-first option

Tabnine's whole pitch is privacy — it can run fully on-premise, which matters for teams under strict data rules. I tested the local deployment angle because a friend's company is regulated and can't send code to the cloud. In that narrow case, Tabnine wins by default: it's the only mainstream option that works offline.

But I'd be lying if I said the completions felt as smart as Copilot or Codeium on normal, non-sensitive work. If you don't have the privacy requirement, you're giving up quality for a feature you don't need. If you do have the requirement, it's the answer — just set expectations with your team that it's a different tier of assistant.

The no-code builders: Bolt, Lovable, and v0

Full disclosure: I went into this part skeptical and a little smug. "Type a prompt, get an app" is a promise I've heard break a hundred times.

Bolt.new and Lovable are the two I hear most about. I gave both the same task: a simple CRUD dashboard with a login screen and a table. And... they did it. Not perfectly — there was a point where Bolt produced a component that referenced a prop that didn't exist, and Lovable's first attempt at the auth flow had me clicking through a modal that appeared before the session check finished. But the iteration loop is what's different: you tell it what's wrong in plain English, it fixes it, and the whole cycle takes minutes, not days.

The honest take: these tools are not replacing developers. They're replacing the gap between "I have an idea" and "I have something to show a non-technical stakeholder." If you're a founder who can't code, Bolt or Lovable gets you a demo in an afternoon that would've cost you $5,000 and three weeks. If you're a developer, they feel like a preview of how much faster you could scaffold internal tools if you stopped being precious about hand-writing every line.

v0 sits somewhere in between: it's best at generating frontend components and UI code that actually compiles into your existing React app. For that narrow job — "give me a nice-looking settings page in my stack" — it's the most practical of the three for a working developer.

Replit AI: the all-in-one that's still finding its shape

Replit is interesting because it's not just an assistant, it's a whole environment — code, hosting, database, AI, all in the browser. The AI is genuinely helpful for beginners, and the "deploy from your phone" moment is real.

But as a professional developer, I found the abstraction layer frustrating when I needed to do something outside its happy path. The moment I wanted a specific package version or a custom build step, I was fighting the environment more than I was coding. Replit is the best answer to "I want to build something without setting up a dev environment" — it is not the best answer to "I have an existing codebase and specific requirements."

What I actually pay for now

After the month, my personal stack is:

Cursor Pro — for the agent-mode edits and multi-file work. This is my daily driver now.
Copilot stays because my employer pays for it and it's still the best autocomplete in meetings when I'm reviewing code in a normal editor.
Codeium as a free fallback for side projects where I don't want to burn Cursor credits.

I cancelled Bolt, Lovable, v0, and Replit after the trial — not because they're bad, but because they solve a problem I don't have (I can already code). I'd recommend all four to non-developers without hesitation, and I wrote that in the reviews we published, even though it would've been easier to dunk on them.

The part nobody tells you

Every one of these tools has a failure mode that's worse than being wrong: being confidently wrong in a way that looks right. Copilot will happily autocomplete a function that references a variable you deleted. Cursor's agent will refactor a file and silently drop an edge case. The no-code tools will generate an app that works in the demo and breaks under real data.

The skill that matters in 2026 is not prompting. It's reviewing. The people getting real value from AI coding tools are the ones who treat every suggestion as a junior developer's draft — read it, question it, test it. The people getting burned are the ones who tab-accept everything and find out three weeks later.

I wrote detailed reviews of all eight tools — including the ones I cancelled — with the exact prompts I used and the bugs I hit. They're part of a bigger project where we're manually testing AI tools instead of trusting listicles: Lingxi AI Hub — every review there was written by a human who actually paid for and used the tool. The coding category starts here, and I've linked each tool's full write-up in its section above via the tool pages.

If you've tried any of these and landed somewhere different, I'd genuinely like to hear it — especially if you've made Bolt or Lovable work for real production code, because I want to be wrong about that.
