Solid 4 stars. Clerk does what it claims and does it well. Not revolutionary but a genuine quality-of-life improvement for my daily coding.

Great experience overall. Clerk is my go-to for team collaboration. The only reason I'm not giving 5 stars is the occasional false positive, but it's getting better with each update.
