I'm building API docs without much front-end work, what should I use?

If you want to build API docs with minimal front-end work, the best options are usually:

1. Swagger / OpenAPI + Swagger UI

Best default choice.

• Write an OpenAPI spec (YAML or JSON)
• Swagger UI automatically generates interactive docs
• Great for:
  • endpoint browsing
  • request/response examples
  • “Try it out” testing
• Works well for REST APIs

Use this if: you want the most common, widely supported solution.

---

2. Redoc

Best for polished, readable documentation.

• Also uses OpenAPI
• Produces cleaner, more documentation-focused pages than Swagger UI
• Less “API tester,” more “docs site”

Use this if: you care more about nice-looking docs than interactive testing.

---

3. Stoplight

Best for a more complete API design/docs workflow.

• Good editor for OpenAPI
• Nice documentation output
• Helpful if you want collaboration and API governance

Use this if: you want docs + API design tooling in one place.

---

4. Postman

Best if your API is already documented in collections.

• Can publish documentation from Postman collections
• Easy if your team already uses Postman
• Less ideal as a long-term documentation source than OpenAPI

Use this if: you already maintain collections in Postman.

My recommendation

If you want the simplest path with little front-end work:

• Use OpenAPI
• Render it with Swagger UI if you want interactive docs
• Or Redoc if you want prettier, more readable docs

Quick decision

• Need interactive testing? → Swagger UI
• Need nicer docs for humans? → Redoc
• Need an all-in-one API platform? → Stoplight
• Already in Postman? → Postman docs

If you want, I can also recommend the best option based on your stack, like Node/Python/Java/.NET or whether your API is REST or GraphQL.
