Billing & plans
One subscription, a set number of agents, flat prices for extras. No meters, no hourly rates: how much your agents run never changes the bill.
Plans
A plan includes a number of agents; every agent gets the same base allocation (2 GB RAM, 5 GB SSD, auto-sleep when idle). Sleeping agents keep their full state and count toward the included number, not toward any extra charge.
| Plan | Price | Included agents | Extra agent |
|---|---|---|---|
| Free | $0 | 3 | Upgrade to add more |
| Starter | $20/mo | 20 | $1.50/mo |
| Growth | $100/mo | 100 | $1.25/mo |
| Scale | $500/mo | 500 | $1.00/mo |
The subscription is charged when you subscribe and on each monthly renewal. Extra agents and add-ons are counted per day and billed in arrears on the next invoice, so an agent that only existed for a week costs a quarter of its monthly price. Canceling keeps the plan through the paid period, then drops the account to the free tier.
Add-ons
Add-ons are flat per-agent monthly prices, set per agent at creation or resized later from the agent's settings. Self-serve ceilings are 8 GB RAM and 100 GB SSD per agent.
| Add-on | Unit | Starter | Growth | Scale |
|---|---|---|---|---|
| Extra RAM | per GB above the base 2 GB | $3/mo | $2.50/mo | $2/mo |
| Extra SSD | per 5 GB above the base 5 GB | $2/mo | $1.50/mo | $1/mo |
| Always-on | per agent, opts out of auto-sleep | $20/mo | $20/mo | $20/mo |
| Identity (email + phone) | per agent, bring your own Inkbox key | You pay Inkbox directly; Maritime wires it up | ||
Always-on is for agents that must react in milliseconds, around the clock; everything else sleeps when idle at no cost.
Free tier
Free accounts get 3 agents forever, all of which can run at once. Base allocation only: no add-ons, no identity, no extra agents. It exists so you can genuinely build and test before paying, not as a trial that expires.
AI budget (LLM calls)
Model calls are separate from hosting. Agents created without your own key route through the Maritime proxy and draw down a prepaid AI budget at provider list price; buy more from the Billing page. Bring your own OPENAI_API_KEY on any agent and that pool is never touched: you pay your provider directly.
Failed payments
If a renewal charge fails you get a 14-day grace period (with email reminders) during which everything keeps running. After that, agents are put to sleep with their state preserved until payment succeeds, and unpaid add-on days are settled automatically on the next successful charge.
Watching spend
The Billing page shows your plan, agent usage against the included number, the date and estimated amount of the next invoice, and the AI budget. Recent activity is the full ledger, one row per charge and debit. Interactive browser sessions (pooled Browserbase logins) bill at roughly $0.30/hour while a session is open.
