We used to send each other our GitHub PR links on Slack to ask for a review. Having Axolo made it a zero-effort thing. Having discussions on Slack is much more natural and Axolo does a great job doing it. The support is amazing as well! Arthur and Sydney proactively reach out to ask if we're facing any issues and even released one feature request within hours!
