  • Private projects, multi branch support and custom domains start at the Startup plan, $113 a month billed annually

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

Stoplight: How many included users are in each Stoplight plan?

Basic includes 3 users, Startup includes 8 users, and Pro Team includes 15 users. Additional users beyond the included count cost $14/month for Basic and Startup, or $27/month for Pro Team.

Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.

Stoplight: Does Stoplight offer a free trial?

Yes, all paid Stoplight plans include a 14-day free trial. The free plan has no trial period as it is always available.

Source
Stoplight: Does Stoplight's free plan have limitations?

Yes, the free plan includes only 1 project and 1 user. Users viewing public documentation anonymously are not counted toward the 1-user limit.
