Decoy
Local server mocks in macOS, all in a lightweight native app
What it does
Decoy lets developers create mock services locally. No need for Docker or heavy Electron apps. I built it to test webhook requests coming from my own applications, testing my API wrappers and seeing how my app reacts to redirects, timeouts and failures. You can even mock full webpages to test your scrapers and AI agents against, without risking being rate limited or blocked. All in a beautiful native app. It weighs only 10MB and starts up super quickly and there is no tracking at all.

Hi HN, I'm opening up the beta for IndigoStack. It's a native macOS app which provides a fresh take on how to run all the services you need for local web development. I've been building it for myself as a Laravel & Drupal developer and I'm now looking to get some beta testers on board! Check it out, and don't forget to sign up to the forums to give us your feedback! https://indigostack.app My motivation: Like many developers I've developed a love-hate relationship with the existing options for local development on a Mac.
