Execution plans
Start with $10 prepaid credit. No subscription required: 6¢ per compute-minute. Regular users can choose a monthly plan.
| Plan | Monthly price | Included compute-minutes | Roughly | Extra minutes | Job deadline | Artifacts |
|---|---|---|---|---|---|---|
| Starter | $5 | 100 | 50 default jobs | 4¢/min | 15 minutes | 250 MB · 1 day |
| Pro | $15 | 400 | 200 default jobs | 3¢/min | 15 minutes | 1 GB · 7 days |
| Business | $39 | 1,200 | 600 default jobs | 2.5¢/min | 15 minutes | 3 GB · 30 days |
A compute-minute is one minute of a Small sandbox (1 vCPU, 1 GB RAM). Pay as you go: Small 6¢/min, Medium 12¢/min, Large 24¢/min. Every run rounds up to a whole minute, and a default job runs 2 minutes. Queue and provisioning time are not billed. Included minutes reset on day 1 UTC and do not roll over; purchased credit persists. Shared worker capacity is not reserved concurrency. AI inference is not included.
Existing paid periods and transition allowances are protected until the expiry shown in usage. New bundled execution allowances do not stack with standalone plans.
