| Free tier | Start free with a $5 usage credit and no card; the Free tier is 5 concurrent sandboxes, 4 h max session, 2 vCPU / 2 GB RAM / 2 GB disk, all templates and SDKs, no persistent workstation unit mixed; metered on wall-clock; credit, not hours: USD 5 of usage at the published per-second rates |

| Limits | - retention-clamped (binding) 30 active hours a month on Personal (100 on Pro), a 4 h maximum session on the free tier and 24 h on Pro source
- volume-quota USD 5 of usage credit on the free tier, no card source
The 30-hour monthly allowance is wall-clock, not a byte quota, and it is the number that decides the plan: 30 hours is 4% of a month. Storage is billed separately at USD 0.15 per GB-month even while the workstation is paused. |
|---|
| Binding | retention-clamped The plan's 30 active hours and the 4 h (free) / 24 h (Pro) session cap clamp runtime before any byte quota could; beyond the allowance the meter runs at USD 0.1656 an hour, which is USD 120.89 for a month. |
|---|
| Identity | email 'Start free with a $5 usage credit and no card' and 'No card. One pip install pilldrops away.' Card types for the paid plans, any authorisation hold, and whether a debit or prepaid card is accepted are not stated on the page read. |
|---|
| Egress | Not published. The pricing page lists three meters only - vCPU-seconds, GB-seconds of RAM, and GB-months of storage - and states no traffic allowance or per-GB rate. The plans are 'bring-your-own-key' and sell the machine, not model usage. |
|---|
| Per-object cap | not applicable: the unit is a machine, not an object; the billed shape is 2 vCPU / 4 GB / 10 GB on Personal |
|---|
| Retention | unknown: Personal and Pro each include '1 persistent workstation', and a paused sandbox bills storage only at USD 0.15 per GB-month, but no page read states how long a paused workstation survives before deletion |
|---|
| Interface | rest, cli Python SDK, MCP server, templates, and a Telegram bridge on the paid plans. The product is an agent-running machine, not a shell you SSH into. |
|---|
| Tooling | The vendor's SDK and MCP; a Telegram bridge for the paid tiers. No SSH or generic compute interface was documented on the page read. |
|---|
| Composes with | The USD 3 Personal plan buys 30 workstation hours a month of a 2 vCPU / 4 GB machine, which is the cheapest way found to keep a small always-warm environment for an agent - but it is 30 hours, not 730, and the metered rate beyond that is USD 0.1656 an hour. |
|---|
| Reliability | Every plan is bring-your-own-model-key, so the machine outlives a provider rate limit but the agent stops when the key's quota does; no suspension or data-loss event was observed. |
|---|
| Notes | Arithmetic at 24/7 on the Personal shape: vCPU 2 × 0.0000140 × 3600 = USD 0.1008 an hour; RAM 4 × 0.0000045 × 3600 = USD 0.0648 an hour; together USD 0.1656 an hour × 730 = USD 120.888; plus storage 10 GB × USD 0.15 = USD 1.50, so USD 122.39 a month. At 300 hours it is USD 49.68 + 1.50 = USD 51.18. The USD 3 plan is therefore a bundle of 30 hours, and the page's own 'rule of thumb' (USD 0.13 an hour for a 2 vCPU / 2 GB sandbox) matches the meters. Region, hosting and the maximum session length on Personal (only free 4 h and Pro 24 h are stated) are unverified. |
|---|
| Evidence note | documented Prices, meters, plan allowances and the no-card claim are all from the vendor's pricing page read. The 24/7 figure is arithmetic on those published meters, not a quoted total: it is what the same shape costs if run continuously outside the allowance. What would raise it: a probe that runs a sandbox for an hour and reads the billed amount. |
