API Error Debugger

What it does

Debug API requests without digging through DevTools. Detect and group 401, 403, CORS, network and client errors directly in Chrome. Fast, local, privacy-first extension.

Automatically detect and group 401, 403, network, client, and authentication issues directly from your browser traffic. No more digging through noisy DevTools logs — API Error Debugger makes failing requests structured, visible, and easier to understand instantly. API Error Debugger helps frontend developers, QA engineers, and technical teams debug failing API requests faster. Instead of manually scanning the Network tab, you get grouped request failures, a visible top issue, likely causes, and practical fixes in one place. It is designed for real browser-side debugging workflows where API calls fail because of invalid credentials, missing headers, blocked requests, expired tokens,…from api-error-debugger.soft-core.dev

  Intercept.rest – Faster API debugging2018 · ▲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. Been a long time lurker here and…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
