4 in 1

Docs, SDKs, an MCP server and monitoring on one subscription, at no extra cost.

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. A custom domain, MDX guides, password protection, AI chat, analytics and PDF export are on every plan.

The same plan generates SDKs in TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, Rust, Swift and Dart and publishes every release, hosts an MCP server whose tools call your API, and keeps watching after release with error reporting inside every SDK, uptime checks, a status page, and logs and traces.

Only on Octri

8 features you will not find in GitBook’s site or docs.

  • SDKs in ten languages

    Generated, regenerated on every spec change and published for you, from TypeScript to Swift and Dart.

  • MCP tools that call your API

    One callable tool per endpoint beside the docs tools, with the list exported for OpenAI and Anthropic too.

  • Error reporting inside every SDK

    A failure in your users’ apps reaches you with the SDK version, language and method, tagged to the release.

  • A status page for your users

    Incidents from your uptime checks publish to 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.

  • 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 shaped in a studio

    Client shape, method names and file layout per endpoint, with the generated code redrawn beside each change.

A reference that arrives already written

GitBook turns your spec into interactive blocks you place in your pages. Octri writes a reference page for every endpoint, then keeps it current as the spec changes.

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, and every spec change becomes a dated changelog entry with breaking changes flagged, without anyone writing it.

Guides are MDX in a visual editor on the published page, with Git sync, a custom domain, password protection, full-text search, an ask-the-docs chat, llms.txt and a markdown copy of every page for coding agents, docs analytics, PDF export and redirects for pages you retire, all on every plan, Free included.

Ten SDKs, built and published

Octri generates, regenerates and publishes SDKs in ten languages from the same spec as your docs.

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, ready to publish to its registry.

SDK Studio sets client shape, method names and file layout for the whole project, one language or a single endpoint, with the generated code redrawn beside each change. The Free plan includes one language, Starter 2, Growth 4 and Business all ten, and the docs show each endpoint’s call through them.

An MCP server that calls your API

GitBook’s MCP server gives agents read-only access to your published docs. Octri’s reads your docs and calls your API.

Octri’s MCP server has seven tools for reading your docs (search, one endpoint in full, the endpoint list, guides, the changelog, your SDKs and the call in your own SDK) and one callable tool per endpoint, which makes the real request. Endpoints you excluded from your SDK get no tool, so the SDK settings double as the agent’s permission list.

It runs locally over stdio with credentials kept on the developer’s machine, or as a shared SSE server for a team, and the tool list exports in MCP, OpenAI and Anthropic formats. Readers get an ask-the-docs chat on the site itself, from the Free plan up.

Monitoring from inside the SDK

GitBook’s analytics follow your readers. Octri also follows the API, and the clients calling it, after every release.

Every Octri SDK carries an error reporter. It ships switched off, and the developer who installs your SDK turns it on with one option. From then on a failure in their application reaches your project with the SDK version, the language, the method and the status, grouped into issues and tagged to the release that introduced it. Credentials and personal identifiers are redacted inside the SDK before anything is sent.

Uptime checks are generated from the endpoints in your spec, an incident publishes to a status page on your own domain and to a banner across your docs, and backend packages in ten languages add logs, traces and latency targets per route, on every plan.

  • Alerts for new issues, regressions and thresholds, to Slack or any webhook
  • No third-party observability vendor in the path; data stored in the United Kingdom
  • Monitoring ingest is never cut off at the allowance, so a bad day’s errors still arrive

Moving from GitBook

The move starts from two things a GitBook site already has: the OpenAPI file its API blocks read, and the Markdown that Git Sync keeps in your repository.

How the move works

  1. Stage 1

    Bring the spec

    You

    Upload the OpenAPI file your GitBook API blocks read, or connect the repository it lives in.

    Octri

    Writes a reference page for every endpoint, with the playground, search and chat switched on.

  2. Stage 2

    Bring the guides

    You

    Paste the Markdown that Git Sync keeps in your repository, swapping {% hint %} and {% tabs %} blocks for Octri’s Callout and Tabs as you go.

    Octri

    Generates an SDK in each language you pick and shows the call through it on every endpoint page.

  3. Stage 3

    Go live

    You

    Copy your site redirects into octri.json, publish, then point your custom domain at Octri.

    Octri

    Regenerates docs, SDKs and MCP tools on every merged spec change, and starts the uptime checks.

Which should you choose?

Choose GitBook

Choose GitBook if one site has to hold a help center and internal docs beside your API, 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. 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, with AI chat, analytics, private docs and a custom domain on every plan, Free included.

Then comes the rest of the subscription. 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

GitBook renders an OpenAPI file into interactive API blocks and does not generate SDKs. Octri generates SDKs in ten languages from the same spec as your docs, regenerates them on every spec change and opens a pull request in each repository.
