Simple, metered, and capped
01
Credits are just dollars
1 credit = $1 of metered usage. Each plan includes a monthly allowance for building, running, and hosting the tools you keep.
02
Charged to the API key
No plan field at provision time. Agents authenticate with a key and usage is billed to it. Limits come from the account behind the key.
03
You set the ceiling
Set an account-wide budget cap. Hit it and work stops spending, so a runaway build cannot create a surprise bill.
Built for production. Isolated compute, private-by-default deployments, an encrypted secrets vault, and hard budget caps. Bring your own cloud on Enterprise.
Questions, answered
What's a credit?
A credit is $1 of metered usage (compute + AI). Each plan includes a monthly credit allowance; you can see usage in real time on your dashboard.
What happens when I run out?
Paid plans roll into overage at ~1.2-1.4x the base rate, depending on plan. The Free plan hard-stops. Either way, your account's budget cap is the hard ceiling.
Can an assistant create surprise costs?
No. Assistants can create work and incur usage, but only inside the budget cap you set on the account.
How do agents provision servers?
Over MCP (the create_server tool) or a REST call authenticated by the agent's API key. There's no plan field and no human approval in the request.
Do servers persist?
Yes. Each agent's server keeps its workspace and state between tasks, and idle servers scale to zero so you're not paying for nothing.
Can I run many agents?
Yes. Issue an API key per agent (or share one) and scope each key to the servers/projects it needs. Usage from every key rolls up against your account's single budget cap.
Can my engineering team take over something we started?
Yes. Each project keeps a full workspace your engineers can open in browser VS Code and continue building in, with the same files the build agent used and a history of every change.
What does a team member get?
Invite people by email and pick a role. Members build: servers, projects, secrets and keys, all inside your account. Admins can also invite and remove people. Only you, the owner, can change the plan or see the card. Free is a single-person account; every paid plan includes seats, and the count above is the whole team including you.
Can I share a live app with my team without making it public?
Yes. A project with a live URL can be set to team access, which means opening it takes a Server4Agent sign-in and membership of your account. You can narrow it further to named people. Anyone else gets a page telling them they do not have access, and never sees the app.
What cloud do you run on?
We run and manage the compute for you, so the product feels the same regardless of which AI assistant you connect. On Enterprise, you can bring your own cloud: we deploy into your account and you keep the keys.
