Hi HN! I just released version 1.0 of Posting, an open source terminal application I've been working on which you might find useful if you work with, test, or develop HTTP APIs! Posting (https://github.com/darrenburns/posting) is an HTTP client, not unlike Postman and Insomnia. However, as a TUI application, it works over SSH and enables efficient keyboard-centric workflows. Your requests are stored locally in simple readable YAML files, meaning they're easy to read and version control. Some other features include: - "Jump mode" navigation - Environments/variables…

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…
