    SpacePigeon▲93

    I switch between a few different “modes” on my Mac every day (work, coding, meetings, personal stuff). Each time I’d end up reopening the same apps and dragging all the windows back into the right Spaces. Super repetitive and honestly kind of annoying. So over the past few weeks I hacked together a small open-source tool called SpacePigeon that basically remembers your whole workspace and puts everything back where it was. Things it can do: Save your current layout (apps + windows + Spaces) Restore it with one click or a hotkey Keep separate presets (like “Work”, “Coding”, “Meetings” etc.)…

    OpenAPI mocks that don't suck – realistic test data, quick setup▲13

    Hi HN! I'm Ankit, the founder of Beeceptor, a request mocking and intercepting tool. This time, I built something new to address a pain I’ve personally felt (and heard from dozens of QA, frontend, and platform teams): making OpenAPI specs actually useful during development. API contracts just sit around as docs often. What if you could 'activate' them, instantly have a realistic, hosted mock server-with contract validation, smart test data, and early usage? So I made _Mockaroo for OpenAPI_, but with brains. It spins up a hosted mock server from your spec in one click. It: - Generates…

    Mocktail – Free, open-source mock API server with a built-in dashboard▲25

    Hi HN, I built the first version of Mocktail years ago. I recently came back to the project, and after a pretty substantial rebuild, v4 is now out. Mocktail is a free and open-source, self-hosted mock API server with a built-in dashboard and database, packaged as a single ~25 MB binary. You can run it locally or on your own infrastructure — no account or hosted service required. You can define endpoints and responses, generate realistic data per request, customize headers, status codes and latency, and inspect incoming requests in real time. With v4, I also added MCP support, so coding…
