What is Protide?

Protide is a native desktop API testing tool built with Rust and GPUI - Zed's GPU-accelerated UI framework. It supports HTTP, GraphQL, WebSocket, gRPC, tRPC, and Socket.IO from a single interface.

It ships with a language server (protide-lsp) for .http files, an MCP server for AI tool integration, and a Zed extension with tree-sitter syntax highlighting.

cargo install --git https://github.com/dreygur/protide protide-lsp

Features

Protocols

• HTTP/HTTPS - GET, POST, PUT, PATCH, DELETE, HEAD, OPTIONS
• GraphQL - query/variables editor with syntax highlighting
• WebSocket - connect/disconnect, send messages, history
• gRPC - proto loading, service/method selection, all streaming types
• tRPC - query and mutation procedures
• Socket.IO - full event support

Request Editor

• URL input with method selector
• Headers, query params, body (JSON, Raw, XML, Form, Binary)
• Authentication - Bearer, Basic, API Key (header or query)
• Environment variables with {{variable}} substitution
• Code generation - cURL, Python, JavaScript, Go, Rust

Collections & Storage

• File-based collections (folders = collections, .http files = requests)
• Request history panel
• Import: cURL, Postman, Bruno, OpenAPI/Swagger
• Export: Markdown

Scripting & Testing

• JavaScript pre/post-request scripts (via rquickjs)
• Test assertions with expect() API
• Request chaining via JSONPath + # @set annotations

Mock Server

• Local HTTP mock server with configurable routes
• Record/proxy mode - forwards to real server, captures responses as static routes

Collaboration

• CRDT-based local-first sync (LWW registers, Lamport timestamps)
• P2P via libp2p - mDNS discovery + Gossipsub
• Bring-your-own-backend file sync (Dropbox, Google Drive, GitHub)
• PAKE secure pairing for LAN peers

Tooling

• LSP (protide-lsp) - hover, completion, diagnostics, formatting, semantic tokens, rename, code actions for .http files
• MCP server (protide-mcp) - JSON-RPC 2.0 over stdio, exposes send_request tool for AI assistants
• Zed extension - syntax highlighting with tree-sitter, LSP integration
