Hephaestus
Modular API testing engine for Postman — zero dependencies
What it does
Hephaestus is an open-source framework that replaces scattered pre/post-request scripts in Postman with a single, version-controlled engine. Each request contains only a small override config. The engine handles everything: 20+ assertion operators, snapshot regression, JSON Schema, OAuth2, secret masking, and retries. Ships with 10+ CLI tools: HTML reports, JUnit XML, run comparisons, watch mode, docs generator, and Docker support. Zero npm dependencies. MIT licensed.

I am happy to announce my minimalist zero-dependency web framework, Minum, is out of beta. http://github.com/byronka/minum You will be hard-pressed to find another modern project as obsessively minimalistic. Other frameworks will claim simplicity and minimalism and then, casually, mention they are built on a multitude of libraries. This follows self-imposed constraints, predicated on a belief that smaller and lighter is long-term better. Caveat emptor: This is a project by and for developers who know and like programming (rather than, let us say, configuring). It is…

I've just released an early version off my project I've been working on for a few months now and would love some feedback. https://github.com/fourlexboehm/faasta I was surprised there isn't yet an open/source and standards compliant way to host wasi-http functions in a way that takes advantages of WASM, a multi tenanted application. If you're not familiar with wasi, Compared to something like AWS Lambda, this approach is much more efficient as a single process can serve 1000s of function invocations concurrently and asynchronously, instead requiring an entire VM.…

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.
