Open source · Free forever
A fast, native API client that runs entirely on your machine. Test REST, WebSocket, and MCP endpoints. Sync collections through Git, pull secrets from Vault, and use environments that auto-switch variables per request.
No account. No cloud. No subscription.
DownloadPush and pull collections to any Git remote. Your team shares API definitions through version control — not a proprietary cloud. Branch, merge, review diffs. Your API workspace is just a repo.
Connect to HashiCorp Vault or AWS Secrets Manager. Secrets sync into environments at runtime — they're never written to disk or committed to Git. Your team shares credentials without ever exposing them.
Define variables per collection or folder — they auto-switch as you navigate between requests.
Chain environments with inheritance, override per-folder, and use {{base_url}} to never hardcode a URL again.
Configure an MCP endpoint, discover its tools, and call them — all from the same interface you use for REST APIs. Inspect schemas, pass parameters, and see responses in real time. The first API client with native Model Context Protocol support.
Method, headers, query params, body, auth — with a syntax-highlighted editor and full import/export.
Organize requests into nested folders. Each collection gets its own environments, variables, and Git repository.
Connect to WebSocket endpoints, send messages with JSON syntax highlighting, and inspect responses in real-time.
Runs on your machine as a native desktop app. Your data stays local — nothing is sent anywhere unless you choose to sync.

Code signing certificates require identity verification programs that aren't available in all countries, and third-party alternatives cost ~$500/year — prohibitive for an independent open-source project. The app is fully open source — you can audit the code and build it yourself.
