Scalar vs Redocly
Redocly is the company behind Redoc, one of the original OpenAPI renderers — the repository dates back to October 2015 and has over 25,000 stars. A very large share of the API documentation on the internet has been rendered by Redoc at some point, and if you are evaluating OpenAPI documentation tooling, Redocly belongs on your list.
This page is written by Scalar, so read it with that in mind. Every claim we make about Redocly links to their own documentation, pricing page, or public repositories. If we have something wrong, tell us and we will fix it.
The short version: both companies ship an MIT-licensed OpenAPI renderer. The difference is what the open edition includes and what surrounds it. Redoc's community edition renders documentation but reserves the try-it console for the commercial hosted product; Redocly's real depth is in API governance and the enterprise portal suite around the renderer. Scalar's open renderer ships with a full API client built in, mounts inside 35 web frameworks, and sits alongside SDK generation and hosted MCP servers driven by the same OpenAPI document.

Where Redocly is stronger
We would rather you hear this from us than find out after switching.
API governance and linting. Redocly CLI is a genuinely excellent tool — linting with configurable rulesets, bundling multi-file descriptions, and decorators for transforming documents, with support for OpenAPI 3.2 down to 2.0, AsyncAPI, and Arazzo. If your organization needs to enforce API design standards across many teams, Redocly has invested in this problem for years and it shows. Scalar's registry supports Spectral rules, but Redocly's governance tooling is deeper and more widely deployed.
Longevity. Redoc has been rendering OpenAPI since 2015. It is battle-tested against a decade of real-world API descriptions, including the malformed ones. That maturity is worth something.
API contract testing. Respect, Redocly's contract testing tool, sends real requests to your API and validates responses against your OpenAPI description and Arazzo workflows. Scalar has no direct equivalent.
The enterprise portal suite. Redocly's commercial platform — Realm, which combines Redoc, Revel (external developer hub), and Reef (internal API catalog), authored through Reunite — is a serious enterprise developer portal product with SSO, RBAC, and analytics on the Enterprise tier.
The try-it console is the fork in the road
Both renderers are MIT licensed. What differs is what the MIT edition does.
Redoc's community edition renders a three-panel reference with search, code samples via vendor extension, and schema documentation. It does not let a reader send a request. Redoc's own README lists the try-it console, automated code samples, mock server, AsyncAPI, and GraphQL as features of the commercial hosted product.
Scalar's open-source renderer includes an interactive client on every operation — and it is not a thin request form. It is the same open-source API client Scalar ships standalone: authentication including OAuth 2.0 flows, environments, cookie and header management, streaming responses, and code generation for 40+ HTTP clients. Your readers test the API in the docs, then keep the same tool on their desktop after they leave.
If interactive documentation matters to you and you want to stay on open source, this is the clearest single difference between the two products.
Where the docs can live
Redoc CE deploys as an HTML tag, a React component, a Docker image, or static HTML from the CLI. These are solid options, and the zero-dependency HTML tag in particular is pleasantly simple.
Scalar additionally ships 35 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 application you already run, at whatever route you choose, and the docs update when your description does. If your OpenAPI document is generated by your framework, this removes an entire deployment step.
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.
Beyond documentation: SDKs and MCP
Redocly is a documentation and governance company, and a good one. It does not offer a production SDK generator. Redocly CLI has an experimental generate-client command that emits a typed TypeScript client, clearly flagged as subject to change, with no other languages and no publishing workflow.
Scalar generates SDKs in TypeScript, Python, Java, C#, PHP, and Go from the same OpenAPI document that renders your docs, with package publishing, automated GitHub workflows, and webhook support. Each language target is $100/month, published on the pricing page.
The same is true for MCP. Scalar hosts an MCP server generated from your OpenAPI document on the Pro plan at $72/month, so agents can call your API with the same source of truth your docs use. Redocly lists MCP servers on their Enterprise tier at $24 per seat/month.
If all you need is a reference page, this section does not matter. If you want docs, SDKs, and an MCP server that cannot drift apart because they come from one document in one pipeline, it is the core of the comparison.
Pricing
Both companies publish their pricing, which we respect — much of this category does not.
The models differ. Redocly charges per seat: Pro is $10 per seat/month with one project and a 100-page limit; Enterprise is $24 per seat/month with 500 pages, SSO, RBAC, and MCP servers; Enterprise+ is custom, billed yearly, via sales. Revel and Reef are separate per-seat add-ons, and the full Realm bundle is $18 to $42 per seat/month on top.
Scalar Pro is $72/month flat, with editor seats and viewer seats included, custom domains, Git sync, Markdown and MDX, and hosted MCP servers. SDK languages are $100/month each. Enterprise adds SSO/SAML, RBAC, and full developer portals.
To be honest about the math: a two-person team that only needs hosted reference docs is cheaper on Redocly Pro. The comparison shifts as the team grows, as page counts pass the tier limits, and as you add products — per-seat, per-product pricing compounds in a way a flat price does not. Run your own numbers for your own team size; both pricing pages give you enough to do it.
Which should you choose?
Choose Redocly if API governance is your primary problem — you want mature linting and rulesets enforced across many teams — or you want an established enterprise portal suite with an internal API catalog, or you rely on contract testing against your OpenAPI descriptions.
Choose Scalar if you want an open-source renderer where try-it is a real API client rather than a paid upgrade, you want docs mounted inside the framework you already run, you want SDKs and MCP servers generated from the same document as your docs, or you prefer one flat published price over per-seat, per-product tiers.

This comparison is based on Redocly's publicly available documentation, pricing page, and public GitHub repositories as of July 2026, and on Scalar's own source. Products in this category change quickly. We have made a genuine effort to be accurate and to state where Redocly is better. If you find something wrong or out of date, please open an issue and we will correct it.
