Isle Rule: Adopt Only When Your Agent Work Sits Inside KiCad or FreeCAD

Isle's managed environments cover KiCad and FreeCAD only, so the adoption decision is really a question of whether your client's design work fits those two applications. The $29/month Tier 1 plan is cheap enough to validate a single-environment workflow, and custom enterprise pricing exists for multi-client deployments, which means the cost question only becomes serious once you are running several client environments at once. The built-in application health checks, artifact checkpoints, and recovery controls are the parts that reduce delivery overhead, because they replace the manual environment setup and error handling an agency would otherwise absorb.

• •At least one retainer client bills for electronics or 3D engineering output: schematic capture, PCB layout, Gerber files, parametric models, or STEP/IGES/STL exports.
• •Your agent stack is framework-agnostic and can point at a managed environment through an SDK or API rather than a specific vendor's runtime.
• •You are prepared to pay $29 per month for a single-environment workflow before committing to a multi-client rollout.
• •The client's design work needs checkpoint and recovery controls so a failed agent run does not destroy the artifact it was editing.
• •You can scope a pilot around one repeatable operation, such as automated PCB layout review, rather than a full design pipeline.
