Auto-generated API documentation with try-it-out straight in the browser. OpenAPI, AsyncAPI, and GraphQL in one interactive surface — the modern Swagger UI alternative for API teams that want developer onboarding measured in minutes, not hours.
// How it works
OpenAPI, AsyncAPI, or GraphQL from the catalog or a Git repo. The API Explorer turns it into an interactive surface — endpoints, schemas, and examples.
Configure parameters, headers, and request body in a form instead of a JSON editor. Auth tokens (OAuth2, JWT, API key) are managed per environment.
Send the request, see the response in real time — with syntax highlighting, status code, and headers. Copy a code sample in the language you need.
// Capabilities
No Postman, no curl terminal, no sandbox. The built-in try-it-out sends requests right from the documentation. Auth via API key, OAuth2, or JWT — parameters visual, response live, with syntax highlighting and status codes.
Headers
Body
Not just REST — the API Explorer supports AsyncAPI for event-driven architectures. Channels, topics, and message schemas for Kafka, MQTT, AMQP, and WebSocket-based APIs with publisher and subscriber flows visualized.

Auto-generated code samples for every language — cURL, JavaScript, Python, Go, Java, C#, PHP. Copy the full snippet with your parameters and auth headers straight into the project, no boilerplate to write by hand.
// Transformation
The difference between a PDF manual and living API documentation — in concrete steps instead of feature lists.
Every API deploy means manually updating pages. Reality: 60% of docs are out of date.
Developer reads the wiki, switches to Postman, copies the URL, builds an auth token, runs the call. Five tools for one request.
OAuth2 flows, JWT tokens, API keys per environment — all configured manually for every request.
AsyncAPI, GraphQL, or WSDL end up in separate viewers. Every format, every tool.
Spec update in the repo → Explorer shows the new endpoints on the next request. No manual refresh.
Read the endpoint, build the request, see the response, copy the code sample. No tool switching.
OAuth2, JWT, API key stored per user and environment. One click, done.
OpenAPI, AsyncAPI, GraphQL, WSDL, RAML, Arazzo, and Swagger — unified rendering.
// Impact
Interactive documentation saves support time, accelerates onboarding, and turns API discovery into self-service. These are the numbers teams measure after rollout.
Developers find endpoints, parameters, and auth flows directly in the docs — no Slack message to the platform team.
From reading the docs to a successful call: under two minutes. Including auth token setup and parameter entry.
OpenAPI, Swagger, AsyncAPI, GraphQL, RAML, WSDL, and Arazzo — unified rendering instead of seven viewers.
// Terminology & differentiation
Anyone searching for "try it out", "API try-out", "API playground", or "API sandbox" means the same function: testing APIs interactively in the browser instead of in Postman.
// Comparison
Many API teams use Swagger UI, Postman collections, or ReDoc for API documentation. That doesn't scale — a dedicated API Explorer solves three core problems.
Open-source viewer for OpenAPI, but not a portal. No access control, no auth management across environments, no multi-format support.
API Explorer: RBAC, auth management, 7 formats in one.
HTTP clients with collections, but not auto-generated from the spec. Collections go stale, token management gets messy beyond 50 APIs.
API Explorer: auto-generated from spec, centralized token management.
Beautiful rendering, but no try-it-out. Developers have to switch to Postman after reading — context switch instead of integrated workflow.
API Explorer: read, test, copy code in one surface.
