The modern Swagger replacement.
Swagger UI was the standard a decade ago. The dated green-bar layout, the no-frills self-host, and the missing AI / mock / MCP surface make it a bad fit for any team shipping a modern API. Outworx ships hosted, AI-powered docs with all of those from $0.

What modern API teams expect
Swagger UI ships none of these.
Swagger UI is a renderer, not a platform. The features API teams expect in 2026 — AI grounding, hosted mocks, MCP, audit log, RBAC — aren't in scope and never will be. Outworx ships all of them on Pro at $9/mo.
AI chat + AI search
Floating Ask-AI drawer grounded in your spec via embeddings. Auto-syncs on every spec push. Swagger UI has a search box; not retrieval-augmented Q&A.
Per-project MCP server
One URL + one token plugs your spec into Claude Desktop, Cursor, Cline. 12 tools out of the box. Swagger UI has no AI surface area.
Free hosted mock server
Schema-walked responses, Prefer-header steering, stateful overrides, GraphQL execution. Swagger UI doesn't mock; you wire up Prism / WireMock.

Why switch
What teams gain by leaving Swagger UI.
Modern UI, not dated
Outworx renders a clean, modern documentation site with responsive design, dark mode, branded styling, and a real Try-It panel — not the 2011-era green-bar layout Swagger UI ships.
Stop maintaining your docs server
Upload your spec and your docs are live in seconds. No bundler, no Docker image, no nginx config, no CI to publish on every spec change.
AI-native — chat, search, MCP
Swagger UI has zero AI surface area. Outworx ships AI chat, AI search, AI auto-generated descriptions, and a per-project MCP server for Claude / Cursor / Cline.
Mock server + webhooks playground included
Outworx generates a mock URL for every spec, with stateful overrides + GraphQL execution. Plus a webhooks inbox for Stripe / GitHub / Shopify HMAC verification. Swagger UI ships none of this.
Modernise your docs.
Hosted modern docs in 60 seconds. AI chat, mock server, MCP, and a real Try-It panel — all from $0.
