Built for modern development

Git-native collections

Store API collections as plain-text files in your repo. Version control, branching, and reviews work exactly like code.

Local & private

Zero cloud dependencies. Collections and credentials stay on your machine. Complete control, no vendor lock-in.

Comprehensive testing

Built-in assertions, test scripting, and automation. Validate responses and wire it straight into your CI/CD pipeline.

Multi-protocol support

REST, GraphQL, gRPC, and WebSocket. One interface for every modern API type, with no context switching between tools.
