Frequently asked questions

What counts as a sandbox hour?+
One sandbox-hour is one hour of a standard sandbox (up to 4 vCPU, 2 GB RAM). Larger configurations consume proportionally more. Billed per-second.
Can I try without a credit card?+
Yes. The Sandbox tier is free forever with 25 hours/month. No credit card required.
What happens if I exceed my plan limits?+
On the Sandbox tier, your sandbox queues until next month. On Launch and Scale, you pay overage at your tier's rate ($0.19/hr or $0.15/hr). We'll notify you at 50%, 80%, and 100% of your allowance.
Do you offer annual billing?+
Yes. Annual Launch is $15/month (billed $180/year). Annual Scale is $63/month (billed $756/year). Both save 20%.
What's included in all templates?+
Every tier gets access to all sandbox templates: playground (Rust, TypeScript, JavaScript, PHP, SQL, Zig), Python 3.11, Node.js 20, and AI tool templates (Claude Code, Codex, Gemini CLI).
Where are sandboxes hosted?+
Hetzner data centers in Germany (EU). All data stays in the EU. SOC 2 Type II audit in progress.
