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.
Get the desktop app
Native builds for macOS, Windows & Linux — unlocking Kafka, mTLS, SOCKS proxies, filesystem-backed collections, and OS-keychain secrets. Auto-updates itself.
Speaks every protocol
Section titled “Speaks every protocol”HTTP
REST / HTTP
All methods, body types, cookies, code gen.
GQL
GraphQL
Query builder, introspection, subscriptions.
RPC
gRPC
Unary, streaming, server reflection.
WS
WebSocket
Connect, send, receive, full history.
IO
Socket.IO
Emit, listen, ack — desktop.
SSE
Server-Sent Events
Live stream viewer with reconnection.
KFK
Kafka
Produce / consume — desktop.
MQTT
MQTT
Publish / subscribe, QoS, TLS — desktop.
MCP
Model Context Protocol
Proxy to any MCP server.
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 using the native rs.* API — fully Postman pm.* compatible. No DOM, no network escape.
Chain requests with workflows
Build request graphs with branching, switches, loops, and parallel steps. Extract variables with JSONPath, regex, or headers. 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.
