Three platforms, one renderer
Web app on Cloudflare Pages, native desktop apps for macOS / Windows / Linux, and a self-hostable Docker image. The same React UI ships everywhere.
Restura
One client. Every protocol. No account, no cloud sync, no telemetry.

Section titled “Speaks every protocol”HTTP

Why Restura
Section titled “Why Restura”Privacy first
No account, no cloud sync, no telemetry. Collections, history and secrets live on your machine — IndexedDB on web, OS keychain on desktop.
Scriptable, sandboxed
Pre-request and test scripts run in an isolated QuickJS WASM sandbox. Postman pm.* API compatible. No DOM, no network escape.
Chain requests with workflows
Extract variables with JSONPath, regex, or headers. Conditional steps. Exponential-backoff retries. Run anywhere — including in CI.
Built-in AI assistant
Chat with OpenAI, Anthropic, or OpenRouter. The assistant can read the current request and response for context — with redaction baked in.
Speaks MCP both ways
Restura proxies any MCP server, and it can be an MCP server — exposing collections, environments, and history to agents like Claude.
