I've used Relay from the early days and got to say it's an absolutely beautiful product for recurring processes like:
- onboarding new people
- sharing all-hands slides
- ensuring smooth sales to CS handoffs
Also, Jacob and the team are extremely responsive. Highly recommend!
I love using GitStart to push frontend changes that take a lot of time but aren't too complex, so I can focus the team on harder problems. Disclaimer: I work there, but I'm also a user as I use GitStart to build GitStart!
