Free, always · No telemetry
Native apps and browser tools — without the upsell.
Two macOS apps, six Chrome extensions, thirty-plus in-browser developer tools. No accounts. No tracking. Just utilities that load fast and do one thing well.
HTTP, GraphQL, WebSocket, SSE in one app. Sub-200ms launch, ~30 MB idle. A Postman alternative that respects your machine.
Dual and quad pane. Command palette (⌘K), global launcher (⌘⇧Space). SFTP, S3, WebDAV, git integration baked in.
