Stop CTRL+F-ing Salesforce Debug Logs: I Built a 100% Client-Side Analyzer

If you develop on the Salesforce platform, you already know the pain of Apex debug logs. You run a process, hit an error, and are suddenly staring at a 20MB wall of text. Trying to manually trace a METHOD_ENTRY to its corresponding METHOD_EXIT or hunting down a specific SOQL query limit feels like finding a needle in a haystack.

While there are a few online formatters out there, they share one massive flaw: Security.

Salesforce debug logs often contain sensitive org data, proprietary logic, and occasionally user PII. Uploading these logs to a random third-party server just to format them is a major security risk.

That’s why I built a solution that runs entirely in your browser.

The Solution: SyntaxFiddle Salesforce Debug Log Analyzer
I added a new Salesforce Debug Log Analyzer to SyntaxFiddle. It is designed to instantly parse massive log files without ever sending a single byte of your data to a server.

Key Features
100% Client-Side Processing: The core philosophy here is privacy. The parsing happens locally in your browser's memory using JavaScript. No database, no server uploads, and absolutely zero tracking.

Clean Execution Trees: Instead of raw text, the analyzer visually structures your log into a collapsible execution tree, making it easy to see exactly which methods are calling what.

Instant Limit & Exception Highlighting: Stop scrolling endlessly to find out where you hit a governor limit or threw a null pointer exception. The tool flags these critical events so you can jump straight to the root cause.

Blazing Fast: Since there is no network latency involved in uploading or downloading the parsed logs, the rendering happens almost instantly, even for hefty files.

Try it out
If you are tired of wrestling with raw logs or worrying about org data leaks, give it a spin.

I’m continuously looking to improve the tool and add more developer-focused utilities to the suite. Drop a comment below if you have any feature requests, feedback, or if you run into any edge cases with specific log structures. Happy debugging!

Why I built Dev Tools that runs entirely on the browser

Hello everyone, this is my first post here and I will admit something: I used to paste the production JWTs into the first JWT decoder google gave me. Same with the Crontabs, with CSV exports full of customer data. Then one day, I was doing a security training targeted for the Security Controls and realized I am doing something really wrong here. Because I didn't know where that data went when I pasted in those online sites.

Most online dev tools works the same way. Broswer sends input to an API, then a Server parses it and result comes back. But somewhere in between, it can end up in logs, analytical pipelines, load balancer records, or may be just in their database.

So I started looking into multiple online tools which doesn't save our data and works only on the client side. There are few sites which does that but for every utility, we need to visit different sites and not all of them promote the 100% client side, or no data logged terms. So we never know. Not to mention we need to visit 10 different sites for 10 different utilities.

So I built SyntaxFiddle: a set of Developer tools that run entirely in the browser.

How it works?

It is a static Next.js export. No backend, no database. Everything is parsed locally so there 's nothing for me to log even if I wanted to.
You don't have to trust me on that. Open Dev Tools, go to the Network tab, load a tool and paste something in. Nothing goes out after the initial page load. You can even turn of Internet and it will keep working.

Currently I have built following tools:

Cron expression Visualizer
Regex tester
JWT decoder
cURL converter to fetch, axios, Python, Go, Apex and more.
CSV and Excel to JSON, XML, SQL and SOQL In clause
JSON to Schema like Zod, YS , Pydantic, Go

It is totally free with no accounts. Please give it a try and share your feedback. I am planning to add more tools to this as I see fit like XML to Schema as many enterprise applications still use XML. Also please let me know in the comments if there is a tool you wish existed and I add it to the roadmap as well.

Thank you for reading through this. Plesae share your feedback.
