Head-to-head
ReadMe vs Mintlify: which one in 2026?
ReadMe is a hosted developer-docs platform from ReadMe, and Mintlify is a docs platform from Mintlify, Inc. that keeps content in Git. Both generate an interactive API reference from OpenAPI. The split is in billing: ReadMe sells AI as add-ons and admin seats, while Mintlify bundles a credit pool into its paid plan.
Verdict
ReadMe is the better fit when a handful of admins run the docs and the $250 Pro tier covers the need, since AI answers for readers stay optional at $150 more. Mintlify ranks higher on this site because its free tier is generous, editors are unlimited, and Enterprise allows self-hosting. Its price jump to $450 is real, so estimate monthly credit use before you commit to the Pro plan.
ReadMe and Mintlify side by side
| ReadMe | Mintlify | |
|---|---|---|
| Price entry | $0 per month on Starter, $250 per month billed annually on Pro | $0 on Starter, $450 per month billed annually on Pro |
| What the free plan covers | Starter costs $0 and includes a custom domain, interactive API reference, usage analytics, a markdown editor and an MCP server, with no editor cap stated. | Starter is free for up to five editors and includes a custom domain, web editor, API playground, search and Git sync, but no credits. |
| First paid step | Pro is $250 per month billed annually, with no monthly rate published. Five admins are included and each extra admin adds $20. | Pro is $450 per month billed annually or $540 billed monthly, with unlimited editors, so headcount never changes the price. |
| How AI is paid for | Ask AI for readers is a $150 per month add-on on Starter or Pro. Pro bundles Ask AI Lite, an AI Linter and an AI Writer. | Pro includes 10,000 credits a month, then $0.01 each. A reader answer uses 25 credits and an automated update uses 250. |
| Keeping docs in sync with code | Bi-directional sync with GitHub, GitLab or Bitbucket, plus the rdme command line tool and an API sync, alongside the markdown editor. | Content is Markdown or MDX living in Git, with feature branches for review. An agent drafts doc updates as pull requests. |
| Writing by non-engineers | Pro adds multiplayer editing, branching and reviews, and the AI Writer proposes edits from code changes on a review branch. | A browser editor offers live collaboration, comments and suggestions, so support or product staff can edit without touching the repository. |
| Training on your content | The privacy policy does not mention training models on customer data. Services are stated as hosted in the United States. | The legal notice says customer content is not used to train language models. Messages reach Anthropic or OpenAI only for inference. |
| Self-hosting | Not offered on the pages read. Enterprise adds audit logs, SSO and OAuth, roles, and removal of ReadMe branding. | Enterprise can run in your own AWS, Azure, Google Cloud or Kubernetes environment, or on-premises, with SSO, SCIM and audit logs. |
| Published security proof | The privacy page names no SOC 2 or ISO certificate, and the security page returned a 404 when checked. | The legal notice points to a separate trust center, which loads by script and could not be read for certifications. |
Where each one wins
ReadMe wins on
- Lower entry for a funded team, at $250 per month against $450, with five admins included
- Free Starter already carries an MCP server and llms.txt, with no editor limit stated
- Review branches, a linter and a writer that checks docs against a style guide
Mintlify wins on
- Unlimited editors on Pro, so adding writers never raises the bill
- Self-hosting on your own cloud or Kubernetes for teams that cannot use a vendor-hosted site
- Published training stance and a pay-per-use credit model with a stated overage rate
Which to pick
Pick ReadMe if
You have a small docs team, want a cheaper first paid tier, and prefer buying reader-facing AI as a separate add-on only when you need it.
Pick Mintlify if
Many people edit docs, your content already sits in Git, or procurement needs self-hosting and a written no-training statement from the vendor.

Frequently asked questions
Is Mintlify more expensive than ReadMe?
On list price, yes. As of November 2026 Mintlify Pro is $450 per month billed annually, while ReadMe Pro is $250 per month billed annually. ReadMe charges $20 for each admin beyond five and $150 for Ask AI, so a larger team that wants reader answers can close much of that gap.
Which tool has a usable free plan for API docs?
Both do. ReadMe Starter is $0 with a custom domain, an interactive API reference and an MCP server. Mintlify Starter is free for up to five editors with an API playground, search and Git sync. Neither free plan lists the paid AI writing features, which sit on Pro.
Do ReadMe or Mintlify train AI models on my documentation?
Mintlify's legal notice says customer content is not used to train large language models, and that Anthropic and OpenAI receive messages only for inference under contracts barring training. ReadMe's privacy policy does not mention model training at all, so ask the vendor for written confirmation if your contract requires one.
Can I host the documentation site myself?
Mintlify lists self-hosting on AWS, Azure, Google Cloud or Kubernetes, or on-premises, as an Enterprise feature with contact-sales pricing. The ReadMe pages we read describe a hosted service run in the United States and name no self-hosted option, so a self-hosting requirement points to Mintlify.
