Openapi Devtools

openapi-devtools is a browser extension and OpenAPI specification generator that captures network traffic to automatically document the API structures of websites and applications. It functions as an HTTP traffic capturer and browser-based documentation tool, mapping real-time network requests into standardized API specifications.

The tool enables API reverse engineering by intercepting outbound HTTP traffic and using heuristic-based merging to combine headers, bodies, and parameters from multiple requests into unified endpoint definitions. These captured definitions can be visualized as human-readable documentation within the browser or exported as downloadable files and shareable strings.

The project covers the full workflow of network request mapping, from client-side specification generation and state-based persistence to final API definition export.

Features

  • OpenAPI Specification Generators - Automatically generates OpenAPI specifications by capturing real-time network traffic from a browser.
  • API Endpoint Merging - Identifies overlapping patterns in paths and parameters to merge multiple request instances into one API definition.
  • Client-Side Spec Generation - Transforms intercepted network metadata into a structured OpenAPI format using a local JavaScript engine.
  • Network Traffic Captures - Records headers and payloads from real-time network requests to build unified API endpoint definitions.
  • API Reverse-Engineering Tools - Analyzes network traffic of websites to reconstruct internal API structures and endpoint definitions.
  • Traffic-to-Spec Mapping - Records and merges real-time browser traffic into a unified set of API endpoint definitions.
  • Heuristic Request Merging - Combines headers, bodies, and parameters from multiple requests into unified endpoint definitions.
  • Content Script Injection Architectures - Injects tracking scripts into active web pages to monitor network traffic without modifying application code.
  • Network Request Interception - Captures outbound HTTP traffic by hooking into browser-level network events.
  • Live API Documentation Generators - Converts live HTTP requests into standardized specifications to document undocumented or legacy APIs.
  • API Definition Exporters - Provides the ability to export extracted API specifications as downloadable files or shareable strings.
  • API Documentation Tools - Provides a browser-based interface for visualizing captured network requests as human-readable API documentation.
  • Browser-Based Visualizers - Renders captured network data into a human-readable documentation format for review within the browser.
  • Request Export Utilities - Saves captured API definitions as downloadable files or shareable strings for external reuse.
  • JSON to Page Rendering - Converts raw OpenAPI JSON specifications into a rendered visual interface of web components.
  • API Specification Tools - Generates API specifications directly from browser traffic.

How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.

    mitmproxy2swagger is a tool that transforms captured mitmproxy network traffic into structured OpenAPI schemas for reverse-engineering REST APIs. It functions as an OpenAPI schema converter and network traffic documentation utility, extracting API endpoints and data structures from captured network packets to create formal technical references. The tool enables the reconstruction of undocumented APIs by converting intercepted HTTP request and response patterns into specifications. It supports merging multiple traffic capture files into a single schema to incrementally expand an API map and ut

    swagger-php is an OpenAPI specification generator and PHP API documentation library. It scans PHP source code attributes and annotations to produce standardized specification files and interactive API references. The tool functions as a schema inference engine that derives data types and schemas from native PHP type hints and generic blocks. It uses reflection-based static analysis to extract metadata without executing application logic and supports recursive schema inheritance to merge definitions from parent classes and interfaces. The project includes a command-line utility for exporting
