Model prompts still go to providers outside Switzerland (the site says the USA)
3 areas for improvement that potential users should consider.
ZeroLog has potential but comes with notable limitations. Consider trying the free tier or trial before committing, and compare closely with alternatives in the developer space.
Yes. Claude Code and Codex sign in with your own vendor account inside the workspace, and the vendor bills you under its plan limits.
Chats, files and workspace disks are stored on a server in Seon (Aargau), Switzerland. Prompts sent to model providers are processed by those providers, which the site says are in the USA.
No. The free plan covers chat, files and vault with 1 GB of storage; containers start with the Mini plan at CHF 9 per month.
Consider ZeroLog carefully or explore alternatives. The free tier is a good place to start.
