Octri vs liblab

4 in 1
Docs, SDKs, an MCP server and monitoring on one subscription, at no extra cost.
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. 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 and a changelog that updates itself. Then Octri keeps going after release, with a hosted 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
8 features you will not find in liblab’s site or docs.
One feature set in all ten languages
Retries with backoff, pagination, streaming, idempotency and webhook signature checks in every SDK you publish.
Kotlin, Rust, Swift, Ruby and Dart SDKs
Five languages beside the five both generate, published to Maven Central, crates.io, Swift Package Manager, RubyGems and pub.dev.
A docs site written from the same spec
Every field explained, errors by status code, a playground and AI chat, hosted on your own domain.
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.
A mock server in every SDK
A local server built from your spec, with request checks and forced statuses, plus a contract test suite against it.
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 Go or Ruby 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.
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 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 a hosted MCP server, 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

See every Octri plan →Moving from liblab
Your spec, languages, auth schemes and package name come across from liblab.config.json. liblab’s own docs now guide its users to the Postman CLI, so this is a good moment to choose where the SDKs go next.
- liblab.config.json
- openapi.json
How the move works
Stage 1
Bring it in
You
Upload your
liblab.config.jsonwith the spec it points at.Octri
Reads your spec, languages, auth schemes and package name, and writes a reference page for every endpoint.
Stage 2
Fill it out
You
Set environments, retries and pagination in SDK Studio, check each language’s package name, 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.
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 liblab
Choose liblab if you need a C# SDK or a Terraform provider generated from your spec today.
Choose Octri
Choose Octri if you want SDKs in more languages, each one as complete as the next. Ten languages, every one with retries, pagination, streaming and webhook signature checks, shaped in a studio and tested against a mock server. 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. 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
liblab joined Postman in November 2025. Its docs now include a guide for moving SDK generation from the liblab CLI to the Postman CLI, with settings moving from liblab.config.json to .postman/config.json. The SDK code liblab generated for you stays in your repositories either way.
