Automated delivery has made production releases safer and has reduced deployment incidents
The first point for improvement is the steep learning curve, where concepts such as services, environment, pipelines, and templates take time to understand. New users often need training before becoming productive, resulting in slower initial onboarding compared to simpler CD tools. An improvement idea is better guided onboarding with more opinionated defaults and examples. The second improvement can be on UI complexity and navigation; the UI can feel cluttered with many options and finding past executions, logs, or specific settings sometimes takes extra clicks, leading to small but noticeable productivity loss. Simplified UI views for common workflows and improved search and filtering could help. I also see cost and licensing as potential areas for improvement, as pricing can feel high for small teams and advanced features are tied to higher tiers, which may limit adoption for startups or smaller organizations. Flexible pricing models and more essential features in lower tiers could address this issue.
