Best OpenSource Claude Cowork alternative?

Hey guys,

Looking for an alternative for Claude Cowork:

• Project Work / Documents
• Integrations like Notion, Gmail, etc.
• Tools like Websearch, PDF creation, etc.

Came over Eigent (https://github.com/eigent-ai/eigent) but cant find any actual reviews about it, what usually is a sign thats not good performing..

Also have tried multiple other frameworks (OpenClaw, Hermes, OpenWebUI Chat Interface) - but those are different use-cases for me.

LLMs will be server through my own server, so should be open for connecting to Ollama, Ninfer, etc.

So anyone knows a good application which behaves like Claude's Cowork?

Thanks )
