Isolated by design
Every account runs in its own environment with its own worker and its own sing-box. Credentials never share a process or a directory.
Zero Start is a managed token pool for Claude, Codex and OpenCode Go. Isolated accounts, dedicated egress, one endpoint — so your team ships instead of juggling keys.
Sign in with your Zero World account. No new password.
The token pool
Every account runs in its own environment with its own worker and its own sing-box. Credentials never share a process or a directory.
If a route goes down, requests stop. No silent direct connections. No quiet account swaps.
Messages, Responses and Chat Completions behind a single Zero Start Max provider.
New upstream models are discovered, then published only when an admin flips the switch.
Access is granted per pool. Usage is metered per model — prompts and responses are never stored.
How it works
Use your Zero World account. Zero Start creates your local profile on first sign-in.
An admin adds you to a pool with Max access. Your available models appear instantly.
Pick Zero Start Max in Zero World and start working. Routing, quotas and egress are handled.
Zero World
Zero World is a desktop workspace where you build tools, finish research and publish the results — with the process attached. Zero Start is the model layer underneath.
