Octri vs Docusaurus
Docusaurus is a framework for building a docs site. Octri is the docs site, written from your OpenAPI file and hosted for you, with SDKs in ten languages, an MCP server and monitoring on the same plan.

1 file
is all Octri needs: upload your OpenAPI file and the reference, playground and SDKs are built from it.
4 in 1
Docs, SDKs, an MCP server and monitoring on one subscription, Free included.
Octri writes your API reference from the spec: every field explained, every error documented with its cause and fix, the call through your own SDK on every page, and a changelog that updates itself. Every merged spec change rebuilds it, with nothing to regenerate or deploy.
The site comes hosted, with search, AI chat, analytics, password protection and a custom domain on every plan. The same plan generates SDKs in ten languages, hosts an MCP server whose tools call your API, and keeps watching after release with error reporting, uptime checks and a status page.
API docs and beyond, head to head
Octri against Docusaurus with its OpenAPI plugin, 29 rows from each project’s own pages on 16 October 2026. Octri is ahead on 18, level on 6, and Docusaurus is ahead on 5.

Only on Octri
8 things Octri does that a Docusaurus site has no setting or plugin for.
A reference that writes itself
Every endpoint described, every field explained and every error documented, from the spec you already have.
A changelog that writes itself
Every spec change becomes a dated entry of endpoints added, removed and changed, with breaking changes flagged.
An error guide for every status code
Each endpoint lists the errors it can return, with what causes each one and how to fix it.
SDKs in ten languages
Generated from the same spec, regenerated on every change, published for you and shown on every endpoint page.
An MCP server that calls your API
Seven tools for reading your docs and one callable tool per endpoint, hosted for every project.
Error reporting inside every SDK
A failure in your users’ apps reaches you with the SDK version, language and method, tagged to the release.
Uptime checks and a status page
Checks generated from your spec, incidents on a status page on your own domain, and a banner across your docs.
Logs and traces for your API
Follow one failing call from a user’s app into your handler, with latency targets per route.
The reference, already written
Docusaurus with its OpenAPI plugin renders the descriptions your spec already holds. Octri writes the reference from the spec, then keeps it current on its own.
Every endpoint gets a page with a description, every request and response field explained, and each error documented by status code with its cause and fix. Each page shows the call through your own SDK in every language you publish, with a playground beside it that sends the real request using the reader’s own credentials.
Connect the repository your spec lives in and every merged change rebuilds the docs as a draft, with a dated changelog entry flagging anything breaking. Publish when it reads right: there is no generate command to run and no site to rebuild or deploy.
A docs site, hosted and ready
A Docusaurus site is assembled: search, analytics and the API reference each come from a service or plugin you pick and configure. Octri’s site arrives with them.
Guides are MDX in a visual editor on the published page. Full-text search, an ask-the-docs chat, docs analytics, password protection, PDF export, llms.txt and a markdown copy of every page for coding agents, redirects and a custom domain are on every plan, Free included, on a site Octri hosts.
The look is yours to set: page layouts, your accent colour, fonts, light and dark code themes, and on Growth your own components, CSS and JavaScript.
SDKs from the same spec
Docusaurus publishes documentation. Octri also publishes the SDKs your readers install, and shows them on every endpoint page.
Octri generates TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, Rust, Swift and Dart. Every client comes with typed models and typed errors, auth from your security schemes, retries with backoff, pagination, idempotency, server-sent events, multipart uploads and webhook signature checks, and lands in its repository as a pull request on every merged spec change.
Every SDK repository carries a mock server built from your spec and a contract test suite. SDK Studio shapes each client per endpoint, with the generated code redrawn beside every change. The Free plan includes one language, Starter 2, Growth 4 and Business all ten.
Past the docs, on the same plan
An MCP server whose tools call your API, and monitoring that starts inside the SDK, are part of every Octri project.
Octri’s MCP server has seven tools for reading your docs and one callable tool per endpoint, which makes the real request. It runs locally with credentials kept on the developer’s machine, or as a shared server for a team, and the tool list exports in MCP, OpenAI and Anthropic formats.
Every Octri SDK carries an error reporter the developer switches on with one option, so failures in their application reach you tagged to the release. Uptime checks are generated from your spec, incidents publish to a status page on your own domain and a banner across your docs, and backend packages add logs, traces and latency targets per route.
Both start at $0. One arrives finished.
Docusaurus is free and open source, and you run it. Octri’s Free plan is free and hosted, with docs, an SDK, an MCP server and monitoring in it.

What each part of an API docs site is on each. On Octri it is part of the plan; on a Docusaurus site it is a plugin or service you choose and run.

| API reference | Written from your spec, rebuilt on every change | A community plugin, re-run when the spec changes |

Moving from Docusaurus
The move starts from what a Docusaurus site already has: the OpenAPI file its plugin reads, its MDX pages, and sidebars.js.
How the move works
Stage 1
Bring the spec
You
Upload the OpenAPI file your plugin builds from, or connect the repository it lives in.
Octri
Writes a reference page for every endpoint, with the playground, search and chat switched on.
Stage 2
Bring the guides
You
Paste your MDX into the editor, turn
:::noteadmonitions into callouts, and lay out the sidebar fromsidebars.js.Octri
Generates an SDK in each language you pick and shows the call through it on every endpoint page.
Stage 3
Go live
You
Copy your client redirects into octri.json, publish, and point your domain at Octri.
Octri
Rebuilds docs, SDKs and MCP tools on every merged spec change, and starts the uptime checks.
Which should you choose?
Choose Docusaurus
Choose Docusaurus if you want an open-source framework to host and shape yourself in React, or your docs need translating into other languages.
Choose Octri
Choose Octri if you want API docs your readers can rely on from day one, without building the site first. Octri writes the reference from your spec, documents every error with its cause and fix, shows the call through your own SDK on every page, and keeps a changelog that updates itself, hosted on your domain with search, AI chat and analytics included.
Then comes the rest of the plan. SDKs in ten languages built and published for you, a hosted MCP server whose tools call your API, error reporting inside every SDK, uptime checks with a status page and a docs banner, and logs and traces for your API, all at no extra cost.
Questions
Octri’s Free plan is free too, and hosted: docs written from your spec, an SDK in one language, a hosted MCP server, AI chat and monitoring. The paid plans add SDK languages, endpoints and history. Docusaurus is a framework you build a site with; the reference, search, analytics, SDKs and monitoring are pieces you add and run.
