What the subscription covers
Every product meters something. Build, Cloud, and Agents pass through what the servers and models cost, plus 50%. Analytics and the APIs charge a flat rate per unit.
Stack0 Build
Describe an app and get a working project.
Metered per unit
The build machine while it runs, and the model calls Build makes for you. Bring your own model key and those are not metered.
Stack0 Cloud
Deploy Pylon apps to a real URL with a database, sign-in, and storage.
Metered per unit
Compute, storage, and bandwidth at cost plus 50%.
Stack0 Agents
A team of agents with unlimited definitions. One agent run at a time.
Metered per unit
The model calls an agent makes, at cost plus 50%. Agent runs themselves are not charged.

Common questions
The subscription is $20 a month, charged upfront, and it includes $10 of usage credits that apply across every product. Usage past the credits is billed at the per-unit rate for whatever ran. There is no markup on top of that rate.
All of them, in two ways. Build, Cloud, and Agents pass through what a server or a model costs, plus 50%: Build meters its build machine and the model calls it makes for you, Cloud meters compute, storage and bandwidth, and Agents meters the model calls an agent makes. Analytics charges $0.10 per 1,000 events, and the APIs charge a flat rate per email, GB, screenshot, extraction, page, call or minute.
Yes, in Build. Calls made with your own provider key are never metered, so you pay the provider directly and Stack0 bills nothing for them. Running a build on your own machine meters nothing either.
You pay the same per-unit rate you would have paid inside the credits. The rate does not change with volume. Nothing stops working.
Yes. Set a monthly limit and Stack0 refuses new work that would exceed it, with alerts before you get there. Spend that cannot be refused without breaking something you already run in production, such as serving bandwidth for a live app, is counted and alerted rather than stopped.
No. Team members are unlimited. The plan limits agent concurrency instead: one agent run at a time, and extra runs queue rather than fail.
Pylon is free and MIT licensed to self-host, with no account required. The hosted platform starts at the subscription; there is no free hosted trial.
Yes. High-volume teams can contact us for committed-usage pricing under a custom contract, which also covers SSO, a custom SLA, and dedicated infrastructure.
