Sandbox – instantly mock REST and SOAP web services

In plain words

Sandbox is a tool for creating mock REST and SOAP web services instantly. It allows developers to simulate web service endpoints without building full backend infrastructure, useful for testing and development workflows. The service launched in 2014 and enables teams to test API integrations before deploying to production systems.

  I was inspired to make a web based ants simulator after watching this video https://www.youtube.com/watch?v=81GQNPJip2Y Any feedback appreciated. Best viewed on Chromium based browsers. Firefox is slow for some reason and Safari is not tested as I don't have a Mac.

  GhostBox – Borrow a disposable little machine from the Global Free TierMay 2026 · ghost.charity · ▲126

  I built this because I was always creating machines on GH actions to test builds on different OS, and I wanted a tight CLI that could do it. I always saw Actions as this great resources and ephemeral machines you could do dev work in just were a natural way for me to work, so this grew out of that workflow. I didn't expect it to blow up, so it wasn't 100% finished when I posted it. But it should stabilize pretty quickly. Happy to know what you think and talk about it.
