Isle plans and what they include

Isle prices by environment-hours, the time an agent spends in a managed desktop application such as KiCad or FreeCAD. Free includes 5 environment-hours per month, a 30-minute maximum session and 1 concurrent environment, with Python SDK access and artifact checkpoints.

Developer is $29 per month for 100 environment-hours, no per-session runtime cap, 5 concurrent environments, persistent Python execution and priority support. Enterprise is custom-priced with unlimited hours and concurrency, custom application environments, dedicated support and SLA guarantees.
