Why Velo

Most API clients are Electron apps that take 5 seconds to launch and chew through 800 MB of RAM before you’ve sent a single request. Velo is built natively for macOS — it launches in under 200 ms, idles under 30 MB, and uses 0% CPU while you’re not interacting with it.

It does HTTP, GraphQL, WebSocket, and Server-Sent Events. It saves nothing to the cloud. There is no account to create. It is free.

HTTP requests

GET, POST, PUT, PATCH, DELETE, plus full header and body editing. Inspect responses with proper syntax highlighting and a tree view for JSON.

GraphQL

Schema introspection, query autocompletion, variables, and result inspection. Works against any standards-compliant GraphQL endpoint.

WebSocket

Connect, send, and receive frames. Inspect connection state, ping/pong timing, and the full message log.

Server-Sent Events

First-class SSE support. Subscribe to event streams, view raw and parsed event data, and reconnect on disconnect.

Local-first

Everything stays on your machine. No telemetry, no remote sync, no account required. Open the file format if you want — it's plain JSON.

Native UI

Built with SwiftUI. Real macOS keyboard shortcuts, real menu bar, real Touch ID for credentials, real dark mode.
