Welcome

Froglet

Sub-second Linux microVMs for agents and developers.

Each sandbox is a Cloud Hypervisor microVM with a vanilla Linux kernel. The rootfs streams in block-by-block from R2 over NBD, so cold start is ~1s regardless of image size. Snapshots capture VM RAM + dirty blocks; restore drops the agent back into the exact instant the snapshot was taken.

Surface

The dashboard, CLI (@kortix/froglet-cli), and SDK (@kortix/froglet-sdk) all talk to the same REST API at https://api.froglet.sh/v1/ over HTTPS with a Bearer key. Everything you can do in one surface, you can do in the others.
