Why people look for alternatives to Codegen

The complaints that come up most often in public discussion — reviews, forums and community threads. Not our opinion, and not the vendor's marketing.

Requires Python expertise and comfort with async programming.
No integrations with popular tools like Slack or VS Code.
Community data is too sparse to confirm reliability at scale.
Beginner skill label is misleading; learning curve is steep.
