How it works

No VPS to manage. No Linux distro to install. No SSH keys to wrangle.

Security and privacy

Your repo and your API keys stay under your control.

isolation

A full virtual machine.

Your workspace is hardware-virtualized, not a shared-kernel container. Every account gets its own VM with its own kernel, isolated from every other tenant.

encryption

Encrypted in transit and at rest.

TLS on every connection. Your storage and your keys are encrypted at rest.

key management

Keys live in a key vault.

API keys are never stored in our database. They sit in a dedicated managed key vault; the vault handles the secrets, we handle the mobile experience.
