A developer happiness product, https://workdna.com. It sends out employee pulse surveys that are purpose-built for dev teams and don't suck to fill out.
Lots of companies just cobble together a Google Form full of irrelevant questions, send it out, and throw their hands in the air when nobody fills it out.
WorkDNA surveys your team on criteria like CI/CD reliability, test flakiness, PR feedback quality, job satisfaction, and psychological safety. The surveys take 20 minutes to set up, 5 minutes to fill out, and are completely anonymous.
