Anthropic announced Monday it has acquired Stainless, a startup founded by former Stripe engineer Alex Rattray whose software is widely used by rival AI labs, including OpenAI and Google.

Anthropic is gradually winding down Stainless’s general-purpose, hosted services. The startup's engine that automatically creates and updates SDKs will no longer be available to the wider market.

Existing clients will retain full rights and access to the SDKs they have already generated, allowing them to modify and maintain them.

The New York-based startup, founded in 2022, rose to prominence in the emerging AI industry for automating the creation and maintenance of software development kits, or SDKs; the libraries developers use to interact with APIs.
