01

Subscribe & get provisioned

Pay via Stripe. We spin up a dedicated Fly.io app just for you — isolated network, separate compute.

02

Deploy your own code

Push any Dockerfile via flyctl deploy or Docker push. Node, Python, Go, Rust — your call. We don't care.

03

Test without fear

Blast APIs, test webhooks, saturate endpoints, run agents. When you're done, hit reset — back to blank in seconds.

Pricing

One sandbox. Yours entirely.

No shared infra. No noisy neighbors. Your own isolated instance.
