Overview
Most API documentation tools let you test one endpoint at a time in isolation. Enlace turns your OpenAPI 3.x spec into an interactive visual execution graph — drag operations onto a canvas, wire one call's output into the next call's input with dynamic tag autocomplete, and run multi-step workflows concurrently right from your browser. Independent branches execute in parallel; dependent ones wait their turn.
It mounts directly into an application you already have. Point it at your OpenAPI 3.x document — however you produce one (FastAPI, Swashbuckle, Springdoc, NestJS, Express, or hand-written) — and it works. There is nothing else to stand up: no server orchestration, no database, and no separate execution backend. Every request fires straight from your browser to your API, keeping tokens and credentials securely in browser memory.
What you can build with it
A chain like: create a customer, then in parallel update that customer
and create a product, then place an order that needs data from both. Each
step's fields can be typed in directly or mapped from an earlier step's
response — so the order's customerId comes from step one automatically,
instead of you copy-pasting an ID between browser tabs.
Where to go next
- Install it in your app — a few lines, whichever framework you're on.
- Try the demo against a sample API before touching your own — five minutes, no setup.
