Shoutout to Fastgen. Love how quickly I can build new backends without thinking about DevOps at all

We started building with Fastgen. It’s a crazy to see how much faster we are able to ship at Unlock. Looking forward to the next round of updates, especially the direct hosting feature

Fastgen is my new favorite way to build automations at Lumos. It is fast and we do not need to think about hosting at all. Hope they add more integrations soon
