When adding a new feature to Checkly or refactoring some older piece, I tend to pick Heroku for rolling it out. But not always, because sometimes I pick AWS Lambda. The short story: Developer Experience trumps everything.AWS Lambda is cheap. Up to a limit though. This impacts not only…
In a recent post on customer feedback I mentioned being a recent convert to chat widget-driven tools. I thought they sucked, but I was wrong. Since then, I actually switched from Drift to Intercom because Intercom's focus — support & communication — matched my business better than Drift's heavy sales focus. To…
