When it comes to developer documentation, choosing the right platform can make or break your team’s productivity. We’ve spent considerable time evaluating both Mintlify and GitBook, and here’s what we’ve learned.
The quick take
Mintlify is a developer-first platform that requires Git integration and launched in 2022. Backed by $67M in total funding, including a $45M Series B led by a16z and Salesforce Ventures at a $500M valuation (April 2026), they’re growing fast and now power documentation for over 20,000 companies, though they aren’t yet profitable.
GitBook takes a more user-friendly approach, offering standalone editing capabilities. Founded in 2014, they’ve built a customer base of 150,000+ startups, enterprises, and open-source projects on a lean seed round (less than $1M) and are profitable.
Let’s dig into the details.
At-a-glance comparison
| Feature | Mintlify | GitBook |
|---|---|---|
| Focus | Developer-first (requires Git) | User-friendly (standalone option) |
| WYSIWYG editing | Poor | Good |
| Founded | 2022 | 2014 |
| Customers | 20,000+ | 150,000+ |
| Funding | $67M total ($45M Series B, Apr 2026, $500M valuation), not yet profitable | Seed funding (under $1M), profitable |
| Subdirectory hosting | Supported (needs Cloudflare or similar) | Supported (needs Cloudflare or similar) |
| MCP / AI support | Beta MCP support, AI chat assistant | Beta MCP support, AI chat assistant |
| Authentication | Enterprise/Custom plan only | Available on Pro plan |
“Code is read more often than it is written, and documentation is read even more.”
Guido van Rossum, Creator of Python
GitBook shines here with a solid WYSIWYG editor. It’s intuitive, and non-technical team members can jump in without training.
Mintlify’s WYSIWYG editing is… well, let’s just say there’s room for improvement. The developer-first approach means editing often feels more like writing markdown in a code editor than composing in a document.
Pricing and value
This is where things get interesting.
GitBook keeps pricing simple: plan + users. Done. Want to remove branding? That’s available on their middle tier. Not too shabby.
Mintlify takes a more complex approach: plan + users + assistant messages + languages. This can add up quickly, especially for larger teams or those operating in multiple markets. Removing branding requires their top/custom tier.
One significant cost difference: translation.
- Mintlify: Custom pricing (you’ll need to talk to sales)
- GitBook: $25 for the first 50,000 words, then $0.20 per 1,000 words
Both platforms offer continuous translation features, which is crucial if you’re serving a global audience.
Scale and maturity
The numbers tell an interesting story.
GitBook has been around since 2014 and serves 150,000+ customers. They’ve achieved profitability on minimal funding, which suggests strong unit economics and a sustainable business model.
Mintlify launched in 2022 and raised a $45M Series B in April 2026 (led by a16z and Salesforce Ventures at a $500M valuation), bringing total funding to $67M, but still isn’t yet profitable. They now power documentation for over 20,000 companies. The company is in growth mode, which means features and pricing could change as they figure out their business model.
File storage and limits
Both platforms have reasonable file storage limits:
- Mintlify: Less than 20 MB for images, 100 MB for other file types
- GitBook: Up to 100 MB per file
For most documentation needs, either will work fine.
Export and portability
Need to export your docs to PDF?
- GitBook: Available on the premium plan
- Mintlify: Only available on custom plan
This might matter if you’re creating downloadable resources, compliance documentation, or offline content.
Link management
Broken links are the silent killer of documentation sites.
GitBook includes broken link detection on their ultimate plan. Mintlify offers smart 404 detection across plans. Both approaches have merit, though preventing broken links (GitBook’s approach) seems preferable to detecting 404s after the fact (Mintlify’s approach).
Modern features: MCP and AI
Both platforms now support MCP (Model Context Protocol) in beta, allowing integration with AI tools like Claude and ChatGPT. If you’re new to the protocol, see our introduction to MCP for how it works and why it matters for documentation. Teams already using a GitHub MCP server alongside their docs-as-code workflow will find Mintlify’s Git-native approach the more natural fit of the two.
Both also include AI chat assistants that can answer questions based on your documentation, and both support integrating external sources into those chat experiences.
Both platforms offer REST APIs and support for OpenAPI specs, making them suitable for modern, API-first documentation workflows.
Analytics and insights
Both Mintlify and GitBook support PostHog and GA4 integration, so you can track documentation usage and user behaviour.
Both also offer customer insight features with thumbs up/down and comment functionality, which is essential for understanding which documentation is working and where users are struggling.
SEO and subdirectory hosting
For SEO purposes, hosting documentation at yourdomain.com/docs (subdirectory) typically performs better than docs.yourdomain.com (subdomain).
Both platforms support subdirectory hosting, though you’ll need Cloudflare or similar setup to make it work smoothly.
Both are also optimised for LLMs, which is increasingly important as AI agents become a primary way users discover and consume documentation. If you want to go deeper on structuring content for AI answer engines rather than just traditional search, see our AEO guide.
Authentication and security
If you need to lock down documentation:
- GitBook: Authentication available on Pro plan
- Mintlify: Enterprise/Custom only
GitBook publishes their security practices at security.gitbook.com. Mintlify has a security page at security.mintlify.com, though there’s no mention of ISO 27001 certification. They did experience a notable security incident in March 2024, now over two years resolved, which they’ve documented publicly.
So, which should you choose?
Choose Mintlify if:
- Your team lives in Git and prefers a docs-as-code workflow
- You’re willing to sacrifice some ease-of-use for tight developer integration
- You have budget for VC-backed pricing and don’t mind potential future changes
- Your documentation is strictly technical and written by engineers
Choose GitBook if:
- You need non-technical team members to contribute
- You want a more mature, stable platform with proven profitability
- You prefer transparent, predictable pricing
- You value a better editing experience over pure Git integration
- You want authentication without paying enterprise pricing
The key question: who will be writing and maintaining your documentation? Answer that, and you’ll know which platform is right for you.
Documentation is a love letter that you write to your future self.

About Growth Method
Choosing a documentation platform is itself a small experiment in disguise: you’re picking a tool, forming a hypothesis about who’ll maintain it, and only finding out months later whether that bet paid off. That’s the same test-and-learn discipline Growth Method brings to marketing more broadly. Growth Method is the agentic marketing platform for B2B teams: plan your strategy, ship campaigns, and learn what works, all in one place, for people and agents.
Whichever platform you choose, publishing the comparison isn’t the end of the work; measuring whether it actually earns more clicks and qualified traffic is. That’s exactly the kind of before/after read our own agents are built to run: hypothesise a change, launch it, then measure organic clicks and CTR against a proper baseline instead of guessing whether it worked.
Get started to turn your next documentation or content decision into a tracked campaign, not a one-off publish.
Frequently asked questions
Which is better for developer portals: Mintlify or GitBook?
It depends on who writes your docs. Mintlify suits engineering teams that already live in Git and want a docs-as-code workflow. GitBook suits teams that need non-technical contributors (marketing, product, support) to edit documentation directly, and want a more mature, profitable platform with simpler pricing.
Does Mintlify’s Git workflow reduce documentation debt?
It can, because every doc change goes through the same pull request review process as code, so docs are less likely to silently drift from the product. The trade-off is that anyone without Git fluency is effectively locked out of contributing, which often recreates documentation debt from the other direction as non-engineers stop updating docs at all.
Is Mintlify or GitBook better for non-technical teams?
GitBook. Its WYSIWYG editor lets marketing, product, and support team members write and publish documentation without touching Git or markdown, while Mintlify’s editing experience is built around code editors and Git commits.
Do Mintlify and GitBook support subdirectory hosting for SEO?
Yes, both platforms support hosting documentation at yourdomain.com/docs rather than a subdomain, which typically performs better for SEO. Both require a Cloudflare-style reverse proxy setup to make it work.
Do Mintlify and GitBook support MCP and AI features?
Yes, both platforms now support MCP (Model Context Protocol) in beta and include AI chat assistants that answer questions from your documentation, making either a reasonable choice for teams optimising docs for AI agents.
