# Cirrun

> Cirrun is just-in-time compute: it runs a job on the cheapest machine that fits across many clouds, syncs every output file while the job runs, verifies the files by SHA-256, and destroys the machine the second the code ends. Billing is per second. Status: private alpha opening late November 2026.
