Proxycaching

What it does

Proxy Caching Server is a lightweight developer tool designed to capture, cache, and replay HTTP and HTTPS traffic locally. Built specifically for development and testing workflows, it acts as a smart local buffer between your application and third-party APIs. Whether you are running end-to-end tests, debugging a web scraper, or building features against rate-limited remote services, this tool ensures your repeated requests hit a blazing-fast local disk cache instead of the internet.

A local HTTP/HTTPS caching proxy for developers — first request hits the real API, every next identical request is served from local cache instantly. proxycaching sits between your app and the internet. First call goes through normally. Every identical call after that? Served from local cache in milliseconds — no network, no cost, no waiting. npm install npm run build npm run start That's it. Your caching proxy is running on :8080 and the admin UI is on :8081 . # First call — hits the real API curl --proxy http://localhost:8080 https://api.example.com/data # Second call — served from cache instantly ⚡ curl --proxy http://localhost:8080 https://api.example.com/data Open the admin UI to see…from github.com

  Talanoa▲345

  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.

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
