Extension Metadata

About this extension
EndpointCompare is a Chrome & Firefox browser extension for developers to compare responses from two API endpoints (JSON or XML) directly in the browser. It allows users to input or detect API URLs, fetch responses, and view differences side-by-side with highlighted changes.

Why EndpointCompare?

Manually comparing API responses wastes time — copying JSON into online tools breaks flow and privacy.
EndpointCompare brings fast, local, and visual diffing into your browser.

Features
EndpointCompare simplifies debugging and validation by making it easy to compare API responses directly in Chrome & Firefox.

Core Features (MVP)
- Tab Selection: Choose API endpoints from dropdowns listing open tabs with API-like URLs.
- Endpoint Input: Enter two API endpoint URLs manually or save them from webpages via context menu.
- Response Comparison: Fetch and display JSON/XML responses side-by-side, with differences highlighted using jsdiff.
