@@ strengths (pros) @@
+ Complete data sovereignty and compliance control via air-gapped self-hosted execution options.
+ Superior technical flexibility through custom code nodes, Git version control, and granular error-handling branch logic.
+ Significantly lower total cost of ownership (TCO) at high execution volumes compared to per-step SaaS automation tools.
@@ trade-offs (cons) @@
- Requires active infrastructure maintenance, database tuning, and runner scaling overhead when self-hosted.
- Fair-code Sustainable Use License restricts commercial sub-licensing and embedded white-label SaaS resale without enterprise licensing.
