4 in 1
Docs, SDKs, an MCP server and monitoring on one subscription, at no extra cost.
Octri writes your 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 your readers can see 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
9 features you will not find in Stoplight’s site or docs.
SDKs in ten languages
Generated, regenerated on every spec change and published for you, from TypeScript to Swift and Dart.
An MCP server that calls your API
Tools to read your docs and one callable tool per endpoint, hosted for you or run on a developer’s machine.
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 your readers can see
Every spec change becomes a dated entry in your docs, 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.
PDF export
Any page of your docs, saved as a clean PDF for readers who need it offline or in a review.
A reference that arrives already written
Stoplight publishes the reference your team designs and describes. Octri writes it from the spec, 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 your readers can see, with breaking changes flagged.
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, built-in docs analytics, PDF export and redirects for pages you retire, all on every plan, Free included.
Ten SDKs, built and published
Stoplight’s docs show request examples in several languages. Octri generates, regenerates and publishes SDKs in ten.
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.
Every SDK repository also carries a mock server built from your spec, with request checks and a contract test suite, which your team and your users start with one command. 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
Octri hosts an MCP server for your API on every plan, with an ask-the-docs chat on the site itself.
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. Every page also publishes as markdown, listed in llms.txt, for coding agents that read docs directly.
Monitoring from inside the SDK
Stoplight’s plans cover design and docs. Octri’s also watch 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 Stoplight
A Stoplight project is a Git repository, so the move starts from what is already in it: the OpenAPI file and your Markdown articles.
How the move works
Stage 1
Bring the spec
You
Connect the Git repository your Stoplight project syncs with, or upload the OpenAPI file Stoplight exports.
Octri
Writes a reference page for every endpoint, with the playground, search and chat switched on.
Stage 2
Bring the guides
You
Paste your Markdown articles into the editor, swapping Stoplight’s callout and tab annotations for Octri components as you go.
Octri
Generates an SDK in each language you pick and shows the call through it on every endpoint page.
Stage 3
Go live
You
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 Stoplight
Choose Stoplight if your team designs APIs in a visual editor before writing code and wants the docs to live in the same tool.
Choose Octri
Choose Octri if you want 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 your readers can see, with AI chat, analytics 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
Stoplight’s docs show request examples in languages such as cURL, Python, Ruby and Java, and its plans list no SDK generation. Octri generates SDKs in ten languages, regenerates them on every spec change and opens a pull request in each repository.
