    Intercept.rest – Faster API debugging▲89

    Sharing an internal tool that accelerated my development work 10-fold, especially with API debugging. Thought fellow developers here might find it useful. As a developer, I often have trouble reproducing errors at the client end. https://intercept.rest lets me debug and monitor API requests and responses. It is similar to the Network tab in Chrome Developer Tools but works for any API: mobile apps, webhooks, frontend etc. After I shared it with a close circle of friends, they found it incredibly useful and even found new use cases, I never imagined.

It was also sometimes painful to create a test page specifically for non-tech users to consume an API. I originally vibe-coded this over a weekend just to make it easier for myself to debug API requests shared as curl commands. It slowly grew into something I found surprisingly useful in my workflow, so I decided to clean it up and share it. uncurl.dev…
