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.

Powering Zero World
One pool.
One pool.
Every frontier model.
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.

The token pool
Infrastructure you'd build yourself.
If you had six months.
Fail-closed egress
If a route goes down, requests stop. No silent direct connections. No quiet account swaps.
One Max endpoint
Messages, Responses and Chat Completions behind a single Zero Start Max provider.
Dynamic catalog
New upstream models are discovered, then published only when an admin flips the switch.
Pools, not keys
Access is granted per pool. Usage is metered per model — prompts and responses are never stored.
How it works
From sign-in to first token
in three steps.
- 01
Sign in
Use your Zero World account. Zero Start creates your local profile on first sign-in.
- 02
Join a pool
An admin adds you to a pool with Max access. Your available models appear instantly.
- 03
Build
Pick Zero Start Max in Zero World and start working. Routing, quotas and egress are handled.
Zero World
Turn ideas into work
worth sharing.
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.
