Propel is the best code review tool we’ve used. It’s no noise, all signal, and saves our engineers hours every week.

We tried a few other tools before Propel, and while some were helpful, they added a lot of noise. Propel’s feedback is clear, relevant, and easy to act on. It really brought clarity back to our reviews.

Trust is everything in code review. Propel earned it with precise, useful comments that actually help us ship better code.

Devin helped us scale output. Propel helped us scale quality. Together they created a feedback loop that lets us ship faster without sacrificing rigor.
