Swagra

Swagra is an AI-powered OpenAPI platform that helps developers explore, test, compare, and mock APIs—all in one modern workspace.

Swagra is a modern Chrome extension for exploring, testing, and understanding OpenAPI and Swagger APIs directly from your browser — a friendlier Swagger UI alternative and a full API client in one. Import an API specification from a local file, a URL, or raw content and instantly browse endpoints, inspect schemas, run live requests, compare specs, and generate mock data — all through a fast, intuitive interface. Everything runs client-side in your browser; there's no backend, no account, and no data leaving your machine. Your specs, auth, environments, collections, and history are parsed in-browser and saved to local storage. Whether you're building new services, integrating third-party APIs, or learning an unfamiliar backend, Swagra helps you understand and work with APIs faster without leaving your browser. ## Features **Import from anywhere** - OpenAPI and Swagger specifications from local JSON files - Local YAML files - Remote URLs - Raw JSON or pasted content - Import existing requests from Postman collections, cURL commands, or OpenAPI specs **Explorer — browse and understand APIs** - Endpoints organized by tags - Instant search across operations - Request and response schema inspection - Parameters, examples, and data models - "Try it out" to send a live request straight from any endpoint **API Client — a full request workbench** - Organize requests into collections with nested folders - Configure headers, query parameters, path parameters, and request bodies - Environments and {{variables}} for switching between dev, staging, and prod - Postman-style variable substitution - Request history to revisit and replay past calls - Run entire folders or collections in sequence - Automatic token refresh with configurable extraction - Live connections over WebSocket / Socket.IO **API Diff — compare two specs** - See exactly what changed between two OpenAPI specifications - Track added, removed, and modified endpoints, parameters, and schemas **Mock Studio — generate data from schemas** - Produce realistic mock data and sample payloads from any schema - Visualize schema relationships with an entity diagram **Responses and tooling** - Formatted responses with status codes and timing information - Generate ready-to-use code snippets (cURL, fetch, and more) - Recent specifications so you can reopen definitions and continue where you left off **Designed for productivity** - Modern, responsive interface - Light and dark themes - Clean navigation built for large specifications - Fast, client-only experience optimized for developers ## Single Purpose Swagra is a single-purpose OpenAPI/Swagger workspace: it lets developers import an API specification (from a local file, URL, or raw content) and then explore, test, diff, and mock that API entirely within the browser. Users can browse endpoints and schemas, send HTTP requests to user-selected endpoints through an integrated API client, compare two specifications, and generate mock data from schemas. Everything runs client-side and is stored locally — the extension has no other function beyond helping developers work with the API specifications they choose to open. ## Why Swagra? Traditional API tools often require switching between multiple applications or managing heavyweight desktop software. Swagra brings API exploration, testing, diffing, and mocking directly into your browser with a streamlined, client-only experience focused on speed, simplicity, and privacy — nothing you import ever leaves your device. ## Perfect For - Backend Developers - Frontend Developers - Full Stack Engineers - API Designers - QA Engineers - Students learning APIs - Teams working with OpenAPI and Swagger specifications Swagger with superpowers — built for developers who want a faster and more enjoyable API workflow.
