I'm the maker. The story: one day I just wanted to send a GET request, and my API client wanted me to log in first — again — and sync something to the cloud. So I built the tool I actually wanted: one that opens in a browser tab and gets out of the way. What's inside: • Live streaming — SSE and chunked responses render chunk by chunk as they arrive (great for debugging streaming/AI endpoints) • Pre/post scripts with a Postman-style pm API, sandboxed away from the page • cURL / OpenAPI / ApiFox import, copy any request as cURL • Environment variables, collections, history, ⌘K command palette • Local-first: everything in IndexedDB, zero analytics What it deliberately doesn't have: teams, cloud sync, or a collection runner. It's a single-user tool and probably stays that way. If you test APIs daily, I'd genuinely appreciate your feedback — especially on what's missing from your workflow.
