Capture HTTP(S)
at Native Speed
Ultra-fast SwiftUI native app powered by high-concurrency Go Core engine. 120 FPS fluidity, automatic SSL decryption, Map Local, Breakpoints, WebSocket/GraphQL inspection, and MCP AI Agent debugging.
Trusted by 800,000+ developers worldwide
From fast-moving solo developers to engineering teams at Fortune 500 companies.
Native macOS app with meticulous detail
Engineered exclusively in SwiftUI and Go Core with C-ABI Bridge to deliver unmatched 120 FPS UI fluidity and minimal CPU/memory footprint.

Complete suite of network debugging tools
Dive deep into network packets to diagnose, mock, and resolve API issues with native SwiftUI fluidity and high-performance Go Core.
Map Local & Mock Rules Workbench
Serve local mock JSON/HTML files or entire directory trees directly to client requests with zero latency. Override HTTP status codes and custom headers to simulate tricky error states without changing application source code.
- ✓ Fast local directory mapping and file tree matching
- ✓ Status code override (200, 400, 403, 500, 504)
- ✓ Dynamic header injection and delay / lag simulation


Live Breakpoint Inspector & Tampering
Pause in-flight requests or responses midway. Inspect and edit query parameters, authorization tokens, or JSON payloads on the spot before continuing the traffic stream to server or client.
- ✓ Real-time pause and resume execution flow
- ✓ On-the-fly tampering of headers, cookies, and body
- ✓ Regex and wildcard matching for targeted endpoints
Visual Diff Workbench & Request Replay
Compare any two captured flows side-by-side with smart semantic diff highlighting. Spot missing headers, subtle schema drifts, or breaking payload regressions between staging and production environments instantly.
- ✓ Synchronized scroll with color-coded diff markers
- ✓ JSON structure and header discrepancy inspection
- ✓ 1-Click request clone, composer, and replay


WebSocket Frames & GraphQL Inspector
First-class inspection for real-time WebSocket communication and GraphQL APIs. View bidirectional text and binary frames chronologically, and parse GraphQL queries, mutations, and variables with formatted tree views.
- ✓ Real-time chronological frame streaming
- ✓ Dedicated GraphQL Query, Variables, and Response tabs
- ✓ Automatic JSON syntax highlighting and schema folding
iOS Simulator & Android ADB Helper
Zero manual network setup. Proxy Lipeaks automatically installs and trusts root SSL certificates in Xcode Simulators and configures Android emulators via ADB with a single click.
- ✓ Automatic Xcode iOS Simulator certificate injector
- ✓ Android ADB emulator reverse proxy & cert helper
- ✓ QR code pairing for physical iPhone and iPad devices

// Claude / Cursor AI Agent pair debugging protocol
> AI: “Analyze the latest failing 502 Bad Gateway response on /api/v1/auth/token”
// MCP Tool Execution: inspect_flow(flow_id="req_9f81a")
Status: 502 Bad Gateway | Upstream TLS Handshake Timeout
Suggested Fix: Set Map Remote rule to fallback staging gateway or apply mock payload.
> AI: “Applying Map Local rule: /api/v1/auth/token -> ./mocks/token-success.json”
✓ Rule applied to active Proxy Lipeaks session in 1.4ms
MCP Server for AI Pair Debugging
Built-in Model Context Protocol (MCP) server enables Claude, Cursor, and autonomous AI agents to query live captured HTTP traffic, analyze upstream error logs, and generate mock rules directly through natural language.
- ✓ Native MCP tools for query, filter, inspect, and mock
- ✓ Zero latency local IPC bridge with Claude Desktop
- ✓ Autonomous root-cause analysis for HTTP 4xx/5xx failures
