Pricing

You are billed based on how much CPU your code actually consumes, measured in core-hours. For example, using 100% of 2 cores for one hour costs $0.2, while using 10% of a single core for one hour costs $0.01. When a standard box is idle with no CPU usage, no charges apply. Keep-alive boxes are billed at a fixed rate per hour by size instead.

• Standard boxes automatically freeze after inactivity. Storage is preserved, but running processes are stopped until the next request.
• When a new request comes in, the box wakes up automatically, similar to how AWS Lambda cold-starts on demand. No manual intervention is needed.
• Keep-alive boxes stay on continuously and are billed at a fixed rate per hour by size instead of auto-pause behavior.

Keep Alive boxes are billed for the time they exist, at a fixed rate by size, billed per second. This is the only charge for that Keep Alive box, so you are not billed separately for CPU or storage on it.

• Small Keep Alive box: $0.0111/hour ($8 per month)
• Medium Keep Alive box: $0.0222/hour ($16 per month)
• Large Keep Alive box: $0.0444/hour ($32 per month)

Storage is billed at $0.1 per GB per month and includes all data on disk, including snapshots. Storage limits are 10 GB for Small, 20 GB for Medium, and 30 GB for Large.

• Up to 10 concurrent boxes.
• 5 CPU hours per month.

• Agents use your own model provider key (Anthropic, OpenAI, OpenRouter, ...). Set it on the box or save it on your account. Upstash does not provide or bill model usage.
• Agent runs, scheduled runs and browser AI calls need a key. Shell, files, git, SSH, previews and browser CDP work without one.

Yes. The default quota for Pay as you go is 1,000 concurrent boxes. This is a soft limit that can be increased on request, similar to AWS service quotas. Just contact us and we'll raise your limit.

Boxes currently run on AWS us-east-1. We are planning to add more regions soon.

Yes, custom Docker container support is planned and coming soon.
