What people are saying
Developers widely praise Sourcery as an essential quality filter in the era of AI-generated code, though some note its file-by-file analysis has limitations compared to newer cross-file tools. It remains highly valued for automating PR reviews and maintaining consistency.
- "My primary job shifted overnight from builder to an exhausted reviewer... Software engineering went from crafting custom furniture to working security at the slop factory. Using AI for verification [like Sourcery] is the only way out." — Encyclotech (July 2026)
- "Honestly I’m glad to have it. If somebody was forcing me to use it and resolve all the dumb or incorrect comments I’d be annoyed, but they aren’t. It’s a useful quality filter, but it is not sufficient [alone]." — porkyminch (August 2026)
