I’ve been using spring.new to come up with a few internal tools I didn't manage to create with Loveable or Bolt, and it’s saved me a ton of time.
I've been lucky enough to be a beta user, and I'm really thankful for this.
Early on, I ran (multiple times) into a weird glitch—after asking for an app or a large change, the agent seemed to be working for a very long time, but once I dared to refresh, I realized it actually finished while ago. I don't think I encountered this bug in the past two weeks, and everything feels snappy now.
If you need to get something complex working fast without digging into code, spring.new is a solid bet.
