Octri vs OpenAPI Generator

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 keys, server-sent events, multipart uploads and Standard Webhooks signature checks, on every plan.

OpenAPI Generator’s own documentation publishes a feature table for each of its generators, and the tables differ: unions are supported in one language and not the next, and the options for retries, pagination and streaming are not there to set. On Octri there is one list, and it holds in all ten.

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. Custom code lives in the SDK repository and is kept through each regeneration by a normal merge.

When a spec change merges, Octri regenerates every SDK and opens a pull request in each repository, so you review the change like any other. Merging it releases the new version to npm, PyPI, Maven Central, crates.io, RubyGems, Packagist, Swift Package Manager or pub.dev, under your own account.

Each SDK also carries a local mock server built from your spec, with request checks and forced status codes, and a contract test suite that runs against it, so every release can be checked the same way. An optional CLI with a subcommand per endpoint is generated beside the SDKs.

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.

Guides are MDX in a visual editor on the published page, with Git sync, password protection, full-text search, an ask-the-docs chat, llms.txt and a markdown copy of every page for coding agents, all on every plan.

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 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.

Your API is watched too. 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.
