Mintlify
Depends
Confidence: Medium
Buy if you run dev-tool/API docs and can absorb $250/mo Pro plus AI credit costs.
| Compare | Stainless | Mintlify |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | API-first companies with public APIs | Dev-tool companies with public API docs |
| Who it's not for | Internal-only APIs nobody else consumes | Small projects . $250/mo Pro is overkill; use free hosting or plain Markdown |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁶ | Mixed: 2024 GitHub-token breach and three November 2025 CVEs (XSS, traversal, RCE), since patched; trust center and disclosure program exist.15 |
| Support quality | No user support reports found | No evidence in sources reviewed |
| Public sentiment | Public discussion is dominated by the Anthropic acquisition and buyer confusion, with no substantive product reviews found.10 | Users love the polish and collaborative editing but repeatedly flag the $250/mo Pro price and AI credit costs as the main pain. |
| Biggest gotcha | Acquisition risk: if Anthropic sunsets the tool, regenerating SDKs and docs elsewhere is real migration work10 | Free-to-Pro jump is large: $250/mo. Multiple reviewers built cheaper alternatives over the cost. |
