Request beta access
The public beta is free — every new account gets a one-time credit of 100 sandbox-hours. We onboard in batches: once you are approved, you collect your API key from the console with the claim link shown after you sign up.
What you get
- A one-time credit of 100 sandbox-hours — paused time doesn't consume it.
- Up to 20 running / 50 paused sandboxes — full limits.
- Firecracker microVMs, E2B-compatible API, internet on by default.
- US region. Best-effort availability — no SLA during the beta.

Email is required; the rest is optional and helps us size the batches.
Save this link. It is the only way to collect your API key once you are approved — we do not send email. Anyone with the link can claim the key, so keep it private.
