Scalar vs Mintlify
Last updated: September 2026
Mintlify is the best-known documentation platform in this category, and for good reason. If you are evaluating documentation tooling, they belong on your list.
This page is written by Scalar, so read it with that in mind. Every claim we make about Mintlify links to their own documentation or pricing page. If we have something wrong, tell us and we will fix it.
The short version: Mintlify is a hosted documentation platform, and a very good one. Scalar is a platform where the documentation layer is open source, embeddable in the application you already run, and shipped alongside an API client and an SDK generator. Which of those matters more depends entirely on who owns your docs and where they need to live.
Mintlify is also well funded: it raised a $45M Series B in April 2026 at a $500M valuation. You are not choosing a vendor that is about to disappear, and neither are we.

Where Mintlify is stronger
We would rather you hear this from us than find out after switching.
Unlimited seats on a flat price. Mintlify does not charge per editor. The free Starter plan includes 5 editor seats, and Pro and above include unlimited seats. For a large writing team, that pricing model is genuinely simpler than per-seat billing, and at a certain team size it wins outright.
Localization. Thirty-plus locales with per-language navigation, banners, and footers, productized rather than bolted on. If you ship documentation in multiple languages, this is a real gap on our side.
Free-tier generosity in specific places. Custom domain, API playground, Git sync, MCP server, and custom CSS and JS are all on the $0 Starter plan. They also give Pro free to non-commercial open source projects.
Two corrections
Mintlify publishes two write-ups of Scalar, in their Swagger alternatives and enterprise developer portals libraries. They are not hostile, and we appreciate being included. Two things in them are out of date.
"No MDX or custom component support." Scalar supports MDX — pages are .mdx, with JSX, expressions, imports, and components including <Callout>, <Button>, and <Tabs>. Our own pricing page lists Markdown and MDX on Pro.
AI readiness listed as "AI chat agent" only, and Scalar Pro at "$72/month with minimum 3-seat requirement." Scalar ships hosted MCP servers, an AI chat and agent surface, and llms.txt generation. Scalar Pro is $150 per month flat with 5 editor seats included, or $125 per month billed yearly.
The two pages also disagree with each other. The first says Scalar has no developer portal workflow; the second credits Scalar with SDK generation, an API registry, and an AI chat agent. We mention it only because if you are comparing the two products using their material, you are working from a stale picture of ours.
Documentation
Both products render OpenAPI into a documentation site with an interactive playground, support Markdown and MDX, generate llms.txt, and expose an MCP server. Both have a visual editor. The differences are in ownership and placement.
Scalar's renderer is MIT licensed. You get themes and CSS variables, arbitrary custom HTML, CSS, and JavaScript on any page, and the option to fork the renderer if you need behaviour we did not anticipate. Mintlify gives you roughly thirty built-in components and custom React components, which covers most needs — but the renderer is closed, so the ceiling is whatever they expose. Their custom CSS and JS is available on the free tier; white labeling is Enterprise.
Scalar's docs can live inside your application. Thirty-five framework integrations — Express, Fastify, Hono, NestJS, Next.js, Nuxt, Laravel, Django, Rails, Go, Rust, ASP.NET Core, Spring Boot and more. You mount the reference inside the app you already run, at whatever route you choose.
Mintlify has no framework middleware. It is a hosted documentation site, with an Astro build-time integration as the closest alternative. This is not a criticism — it is a different product shape, and if you want a standalone docs site it is the simpler one.
Self-hosting terms differ sharply. Scalar's renderer is MIT and self-hostable on any plan. Mintlify's self-hosting requires Enterprise, is scoped as an engagement with your account team rather than a self-serve install, and they document sizing at roughly 45 to 60 vCPU and 160 to 220 GB of memory.
The site you are reading is the product. scalar.com — this page, the pricing page, the guides, the API reference, and the blog — is built and hosted entirely on Scalar Docs from a single scalar.config.json. We do not maintain a separate marketing stack.
The API client
Scalar ships a standalone, open-source API client — desktop and web, offline-first, with environments, Postman-compatible scripting, and code generation for 40+ HTTP clients. Mintlify's playground lives inside the documentation site only; there is no separate client to download.
To be precise about this: Mintlify's in-page playground is capable, and "no API client" does not mean "no API testing." The difference is whether your users get a tool they can keep using once they have left the docs.
SDKs, and the dependency question
Mintlify does not generate SDKs. They render code samples produced by other tools — their SDK examples guide covers Speakeasy and x-codeSamples in your OpenAPI document.
That integration model works well right up until a dependency disappears. Stainless, which Mintlify also used to document as an SDK integration, announced in May 2026 that they are joining Anthropic and winding down their hosted products, including the SDK generator, with new signups closed. Mintlify has since removed its Stainless integration page.
We raise this because it is the structural difference, not to score a point. When docs and SDKs come from separate vendors, your documentation's code samples depend on a company you did not choose and cannot control. Scalar generates both from the same OpenAPI document, in the same run.
If you are on Stainless today, we have a migration guide.
The wider landscape
Mintlify is not your only alternative, and the category has moved considerably in the last year.
| Scalar | Mintlify | Fern | Stainless | |
|---|---|---|---|---|
| Status | Independent | Independent, Series B April 2026 | Acquired by Postman, Jan 2026 | Winding down |
| Docs renderer | MIT | Closed | Not public | Astro, self-hostable |
| SDK generation | Native | None | Native, 9 languages | Winding down |
| Self-hosting | Any plan | Enterprise | Enterprise | Yes |
| Framework integrations | 35+ | None | None | None |
| Standalone API client | Yes | No | No | No |
| Entry paid tier | $150/mo | $450/mo | Free, then Enterprise (custom) | Not available |
Fern was acquired by Postman in January 2026. They say the product and roadmap are unchanged. Their SDK generators are genuinely Apache-2.0 and their protocol support is broader than ours — AsyncAPI, gRPC, and OpenRPC alongside OpenAPI. Their docs renderer is not public. We compare in more detail on our Fern page.
Stainless is winding down following the Anthropic acquisition. Their docs platform never left public beta. Existing customers keep the SDKs they generated; what stops is regeneration.
Mintlify versus Fern is the comparison most buyers in this category actually run, so it is worth being straight about. Fern's free docs plan is generous — 10 members and 1,000 pages — and Fern generates SDKs natively; above free, Fern is Enterprise with custom pricing. Mintlify publishes a Pro price and gives unlimited seats from Pro upward. Both are hosted-only in practice, neither offers framework middleware, and neither ships a standalone API client. Mintlify publishes their own comparison; so does Fern. Reading both is genuinely more useful than reading either.
The pattern worth noticing: on the two things Scalar treats as core — an open documentation layer you can embed anywhere, and an API client your users keep — none of the three competes.

Prices checked on 26 September 2026. For a team of five or fewer editors, Scalar Pro costs less and includes an SDK. For a large writing team, Mintlify's unlimited seats on Pro can come out ahead.
Mintlify vs Scalar
If you run your docs on Mintlify today and they are working, the case for staying is strong. Your writers like the editor, your content is in MDX, localization is handled, and Mintlify's Pro plan does not grow with headcount. A well-funded vendor with a polished hosted product is a reasonable place to be.
The case for Scalar usually starts somewhere other than the docs site. You need SDKs, and you would rather not add a separate generator whose code samples your docs depend on. You want the API reference mounted inside the application you already run, or self-hosted without an enterprise engagement. You want an API client your users keep after they leave the docs. Or you want an open-source renderer you can fork when you hit a limit.
Moving is mostly a content job. Your OpenAPI document renders in Scalar as it is, and Scalar Docs reads Markdown and MDX from Git. Mintlify-specific components will need mapping to Scalar's components, which is the part to budget time for.
Which should you choose?
Choose Mintlify if your documentation is owned by a writing or marketing team rather than engineers, you need localization across many languages, or you want unlimited editors on a flat Pro price.
Choose Scalar if you want a documentation layer you own outright under MIT, you want to self-host without an enterprise contract, you want docs mounted inside your existing application rather than on a separate hosted site, you want SDKs and docs generated from the same document by the same vendor, or you want a real API client alongside your docs.

Frequently asked questions
How much does Mintlify cost?
As of September 2026, Mintlify's pricing page lists Starter at $0 with 5 editor seats, Pro at $450 per month billed annually or $540 billed monthly with unlimited seats, and Enterprise on request. Scalar Pro is $150 per month, or $125 per month billed yearly, with 5 editor seats.
Does Mintlify generate SDKs?
No. Mintlify renders code samples from SDKs generated elsewhere, such as Speakeasy, or from x-codeSamples in your OpenAPI document. Scalar generates SDKs natively; TypeScript, Python, Go, Java, Kotlin, Ruby, and a CLI are generally available, and C#, PHP, Rust, Swift, Dart, and C++ are experimental.
Can I self-host Mintlify?
Only on Enterprise. Mintlify's self-hosting guide scopes it as an engagement with your account team. Scalar's API reference is MIT licensed and self-hostable on any plan.
Does Scalar support MDX like Mintlify?
Yes. Scalar Docs supports MDX, with JSX, expressions, imports, and built-in components. Mintlify's custom React components do not carry over as they are, so expect to rebuild those.
Is Mintlify or Scalar better for localization?
Mintlify. It supports 30+ locales with per-language navigation, banners, and footers. If you publish documentation in many languages, that is a real gap on Scalar's side.
