Octri vs Stainless
Octri reads the same OpenAPI document Stainless did and produces the same two things, docs and client libraries, from it. It adds ten languages, monitoring inside every client, and a free tier you can prove the move on before committing to it.
Stainless: Stainless generated client libraries from an OpenAPI document. Its hosted products are winding down and it is not taking new projects.
| Capability | Octri | Stainless |
|---|---|---|
| Docs and SDKs | Both | Both (ended) |
| SDK languages | 10 | 7 |
| Shaping the SDK | Visual studio | Config files |
| Monitors the SDKs it generates | Yes | No |
| Monitors your API as well | Yes | No |
| Status page for your users | Yes | No |
| Every endpoint callable by an assistant | Yes | No |
| Starts at | Free, then $49 a month | Not sold |

What Octri adds
Everything below comes out of the same OpenAPI document you would give Stainless.
What ends with the hosted generator is the pipeline that kept your SDKs in step with your API. That is the part worth replacing, and replacing it does not have to mean settling for less: Octri covers ten languages, publishes them to the registries your users already install from, and instruments each one so a failure in production reaches you tagged to the release that caused it. The input is the spec you already have.
- A generator that is taking new projects.
- Monitoring inside every generated client, which Stainless never offered.
- Ten languages from the same spec, with a documentation site beside them.
- A free tier, so the migration can be proved before it is committed to.
- A visual studio for shaping each SDK, per endpoint.
- Publishing to npm, PyPI, Maven Central, crates.io, RubyGems, Packagist and pub.dev.
The row with one entry
Generated SDKs are the least observed code most API teams ship.They run inside other people's applications, where your own instrumentation cannot reach. Because Octri generates the client, it can instrument it: an error is reported back with the SDK version, the language and the method that failed, tagged to the release that introduced it.
It is the one capability on this page that a tool has to generate the SDK to offer at all.
Questions
You keep them and the right to modify them. What ends is the pipeline that regenerated them as your API changed, which is the part worth replacing.

Put them side by side on your own spec
The free tier publishes a real docs site and one SDK, so the comparison stops being a table.
