FAQ
Quick answers
Is this Claude Cowork?
No. OpenGolem is an open-source version of the Claude Cowork idea, and currently a fork/rebrand of Open-Cowork.
Why use it?
Because OAuth is the wedge. You can use existing Gemini, Codex, and Antigravity accounts instead of defaulting to expensive API-key usage.
Do I still need API keys?
Only for providers that are not covered by the supported OAuth flows.
Will this deploy on Netlify?
Yes. This site is a simple static site, which makes Netlify deployment straightforward later.
