Which one is for you
Pick Fern if
- Fits if you maintain an OpenAPI spec and want a hosted docs site at no cost to start
- Works for small API teams that want an API explorer and a custom domain on the free plan
Look elsewhere if
- Skip it if you need SSO or SCIM, which are Enterprise only
- Tight if you outgrow 1 site, 1,000 pages or 10 members, as the next step is a sales quote
- Not for you if you want to remove Fern branding or add custom CSS and JavaScript without Enterprise
- Watch out: SDK pricing sits on a separate tab that this listing did not read
Pick Redocly if
- Fits if your API docs live in Git and developers update them
- Works for teams that need unlimited readers and seats at one price
Look elsewhere if
- Pricey if you're a small team, with $249 a month billed annually as the entry
- Not for you if you want a free hosted plan, as there isn't one
- Watch out: SSO, role-based access and the API catalog need Scale at $729 a month
- Watch out: extra projects cost $390 a year each, and the monthly-billing price isn't shown
How we grade them
| 2.6GPAFernGood | 1.8GPARedoclyWeak | |
|---|---|---|
| Value for money | BThe Free plan costs $0 and the only other plan is a sales quote. Free is in the cheapest group, but there is no published price in between. | D$249 a month billed annually for 3 projects, which is where the dearest tenth of docs tools starts. Extra projects cost $390 a year each. |
| Free plan and trial | BFree plan with 10 members, 1 site, 1,000 pages and 2,000 page generations a month, which one small team could live on. | CA 30-day trial on Pro with no card. No free hosted plan after it. |
| Features | CDocs from several API spec types, an explorer, a web editor and SDK generation. The listing shows gaps: SDK pricing was not read, and custom CSS, SSO and branding removal are Enterprise only. | CInteractive API reference, docs as code, a mock server and an MCP server. The listing's own gaps: typed SDK generation is early access, and SSO and role-based access need Scale. |
| Ease of use | CNo store rating on record. You point it at your API definitions or a repository, which takes some setup. | DNo store rating on record. Docs as code means config files and a Git workflow. |
| Platforms and integrations | BWeb product that reads OpenAPI, AsyncAPI, GraphQL and gRPC, plus Postman. No desktop or phone app is named. | BWeb with GitHub, GitLab, Bitbucket and Azure DevOps links. No apps. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
