Theneo 2.0 vs Mintlify
Theneo 2.0 is an AI-generated API portal: Business about $120/workspace/month (annual; about $150 monthly), Business and above include unlimited Search AI and Theneo AI, free Starter available. Mintlify is MDX docs-as-code: known for design quality, Pro at about $450/month per third-party Oct 2026 audits (annual; about $540 monthly), AI metered by credits, free Starter has no AI features - note Mintlify has repriced multiple times in recent years, verify on the official site before signing. We ran no hands-on test and don't judge generation quality. Teams wanting a usable portal generated from OpenAPI in one click without hand-writing MDX look at Theneo; devtool companies with existing MDX/Git workflows wanting documentation design quality with sufficient budget look at Mintlify.
| Decision point | Theneo 2.0 | Mintlify |
|---|---|---|
| Best suited to | API teams that want documentation generated and kept in sync with code repositories. | Teams maintaining developer docs that need to stay current with the product. |
| Plans and cost | Starter free (1 public project, 2 private projects, 20 members, 100 GPT search results, 2,000 TheneoAI assists, automatic changelog, API Explorer). Business $120 per workspace per month billed annually ($150 month-to-month; up to 7 projects, 50 members, unlimited search AI and TheneoAI, custom branding and domain, 1 developer portal). Growth $400 billed annually ($450 monthly; custom CSS and AI assistant prompts, up to 20 portals, IP allowlisting, Slack or Teams 1:1 support). Enterprise custom (self-hosting, SAML SSO, OAuth 2.0). Formats: REST, AsyncAPI, SOAP, GraphQL, gRPC; sync from GitHub and Bitbucket, VS Code extension, Postman sync. | Starter free (5 editor seats). Pro $450/month billed yearly or $540 monthly, with a 14-day trial including 5,000 credits. Enterprise custom. |
| Limitations | Theneo's value depends on keeping documentation in sync with code: teams that do not connect GitHub, Bitbucket, or Postman will drift out of date quickly. The Business tier caps at 7 projects and 50 members, so larger organizations must step to Growth or Enterprise. | Confirm the current plan limits and credit mechanics on the pricing page before committing. |
