RequestScope: I lost 1k users on my Chrome extension due to bugs. I spent 3 months fixing it and adding API regression tracking

A while back, I built a Chrome extension to fix a few pain points I had with standard browser DevTools. It hit \~1,000 active users at its peak, but I ended up losing most of them due to bugs and a lack of real long-term value.

Instead of scrapping it, I spent the last some time fixing the underlying bugs and rebuilding the tool around a bigger problem: **knowing when an API quietly breaks while you're browsing or testing.**

The biggest addition in this update is out-of-the-box API regression testing.

**How it works:**

* **Baseline Snapshots:** Add your target domain to an allowlist and save a baseline of your HTTP requests and payloads.
* **Flexible Diffing:** Choose whether to monitor for schema changes (added/removed keys), value shifts, or both.
* **Silent Deviation Alerts:** As you browse, it checks incoming traffic against your baselines and pops a notification if an endpoint deviates or fails—even if your web app handles the error silently or DevTools is closed.

**Other key additions:**

* Mocking API requests and responses directly in-browser
* Performance tracking and side-by-side diffs over time
* Exportable session reporting
* Full background request tracking without keeping the DevTools panel open

I'm trying to make this genuinely useful for developers and QA workflows. If you give it a try, I’d love to know: what feels clunky, what's missing, or what breaks? Harsh critiques are welcome.

P.S. This is still work in progress and needs more tuning, bug fixing so looking for genuine feedback
