Anthropic bought Stainless and shuttered its SDK generator. Cloudflare open-sourced Forge instead.
The New Stack reports that Anthropic bought Stainless and then shuttered its SDK generator. The same report says Cloudflare open-sourced Forge instead, presenting the release as an alternative after the generator's closure. The source ties the two events together: an acquisition by Anthropic removed an existing SDK generation tool, and Cloudflare responded by publishing Forge as open source. The excerpt provides no details on the terms of the Stainless acquisition, the date the generator was shut down, the license under which Forge is released, the languages or platforms Forge supports, or how Forge compares in output to the closed generator. It also does not state whether Cloudflare built Forge specifically in response to the shutdown or had it in development beforehand. Because the source text is limited, the account here stays with what it states: Anthropic acquired Stainless, the SDK generator was shuttered, and Cloudflare open-sourced Forge. Developers who used the Stainless generator to produce client libraries are the implied audience for the Forge release, but the source does not describe migration steps, compatibility, or support commitments.
Developers who generated client SDKs with Stainless lost that tool after Anthropic's acquisition, and Cloudflare's open-source Forge is presented as the replacement.
