Anything API▲656Hey HN! We built Notte, a browser infrastructure and agents platform. Many of our users automate UI workflows or extract data from sites that don’t have APIs. In practice, we noticed that once an agent understands how a site works, parts of the task can often run without a browser by interacting with the same network requests the site uses. So we built Anything API: describe a browser task, and our agent explores the site, builds a function, tests it against your description, and deploys a callable REST endpoint. No infra to manage. How the build works: - Describe the task (best results come…

Apidog▲570Development teams often struggle with using multiple tools like Postman and Swagger for API design, development, and testing. This fragmented approach leads to outdated API specs and chaotic collaboration. So we built Apidog: a single, unified API platform for team collaboration. It has a beautiful interface that makes it easy to create API spec, generate request data from API spec, validate responses, create mock data, orchestrate test scenarios, and publish API documentation. Apidog = Postman + Swagger + Mock + JMeter.

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…

BoringSSL and nghttp2. Matches JA3N, JA4, and JA4_R fingerprints. Supports HTTP/2, async/await, and works with Cloudflare-protected sites. Not trying to compete with curl_cffi - just a learning project that turned into something functional.
