The low-cost cloud sandbox where AI agents actually live
Pay for vCPU, memory and disk separately while the sandbox runs; when it sleeps or is deleted the compute meter stops and you are left with disk cost only.
Launch Claude Code, Codex, OpenClaw, OpenCode, Hermes, Grok or your own Docker image, each in its own tenant-isolated sandbox.
Files survive sleep, restarts and weeks of inactivity, and agents can be attached to cron-style schedules so work runs unattended.
Expose individual ports publicly, attach your own domain, or keep everything behind an API key on an authenticated URL.
Turn plain-English schedules into ready-to-paste cron expressions
Type a schedule in plain English — 'every weekday at 2 PM', 'every 30 minutes', '15th of each month at 3 PM' — and receive a standard five-field cron expression to copy.
The site states all conversion happens in your browser with no scheduling data stored or transmitted to external servers, keeping infrastructure details private.
Output targets standard Unix cron format, working across Linux crontab, Vixie cron, macOS cron, AWS EventBridge, Kubernetes CronJobs and CI/CD pipeline definitions.
Documents each cron field, explains special characters like *, /, L, W and #, and shows conversions for time-based, day-based and monthly schedules.
