Speakeasy SDK alternative

Octri vs Speakeasy

Both generate SDKs from your OpenAPI spec and open a pull request when it changes. Octri builds ten languages to one feature set, writes and hosts your docs, runs your MCP server and watches your API once it ships, with every price on the page.

4 in 1

Docs, SDKs, an MCP server and monitoring on one subscription, from a free plan.

Octri generates SDKs in TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, Rust, Swift and Dart, built to one feature set, shaped per endpoint in SDK Studio and tested against a mock server in every repository on every plan. Each spec change arrives as a pull request, and merging it publishes the release.

The same spec writes your docs site, with every field explained, every error documented, a playground on every endpoint and a changelog that updates itself. Then Octri keeps going after release, with an MCP server, error reporting inside every SDK, uptime checks, a status page on your domain, and logs and traces for your API.

Only on Octri

7 features you will not find in Speakeasy’s site or docs.

  • Kotlin, Rust and Dart SDKs

    Three languages beside the seven both generate, published to Maven Central, crates.io and pub.dev under your own name.

  • A docs site written from the same spec

    Every field explained, errors by status code and the call through your own SDK, hosted on your own domain.

  • A playground and AI chat for readers

    Readers send real requests from the endpoint page and ask questions of the docs, on every plan.

  • A changelog that writes itself

    Every spec change becomes a dated entry of endpoints added, removed and changed, with breaking changes flagged.

  • SDKs shaped in a studio

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

  • 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.

Ten languages, one feature set

Every Octri SDK handles the same cases, so the client your Kotlin or Rust users install is as complete as the TypeScript one.

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

The Free plan includes one language, Starter 2, Growth 4 and Business all ten. Each spec change lands in the SDK’s repository as a pull request, and merging it publishes the release to its registry under your own account.

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, and every SDK carries a local mock server and a contract test suite on every plan.

A docs site that arrives already written

The spec that builds your SDKs also builds a hosted docs site on your own domain, so there is no second docs platform to buy and keep in step.

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, PDF export and redirects for pages you retire, all on every plan.

An MCP server in every plan

Every Octri project has an MCP server for your API, regenerated with the docs and SDKs, from the Free plan up.

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.

Your SDKs, reporting back

Because Octri generates the client, it can instrument it. That is the part of the product that keeps working after an SDK ships.

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.

  • 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 Speakeasy

Your spec, languages, SDK name and package name come across from workflow.yaml and gen.yaml, with method names, pagination and streaming from the x-speakeasy extensions already in your spec.

  • workflow.yaml
  • gen.yaml
  • openapi.yaml

How the move works

  1. Stage 1

    Bring it in

    You

    Upload .speakeasy/workflow.yaml and gen.yaml with the spec they point at.

    Octri

    Reads your spec, languages, SDK name and package name, carries over method names, pagination and streaming from your x-speakeasy extensions, and writes a reference page for every endpoint.

  2. Stage 2

    Fill it out

    You

    Apply any overlays to the spec first, check each language’s package name in SDK Studio, and move any hook code into the SDK repository.

    Octri

    Generates every SDK, with its tests and mock server, and shows the call through it on each endpoint page.

  3. Stage 3

    Go live

    You

    Publish each SDK under its existing package name as a new major version, then point your docs 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 Speakeasy

Choose Speakeasy if you need a C# or Unity SDK or a Terraform provider generated from your spec today, or an MCP gateway for the agents your own company runs.

Choose Octri

Choose Octri if you want your SDKs, your docs and what happens after release in one place. Ten languages, every one with retries, pagination, streaming and webhook signature checks, shaped in a studio and tested against a mock server on every plan. Your docs arrive written from the same spec, with every error documented and a changelog that updates itself, on your own domain.

Then comes the rest of the subscription. An 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

Yes. Its SDK generation page is live on 24 October 2026. Its home page and pricing page now lead with its AI control plane, and the pricing page lists usage prices for that product only, so an SDK price is a question for Speakeasy.
