Hey @Patrick J! Good to see you here. That's great to hear that you tried it. So for production, I've got a couple of thoughts, that I'll add to our FAQ soon. The main change SST is doing is on the local development side. We've got Seed users that've been using it in production since October. But the one area that still hasn't been tested enough is the bundling with esbuild. There are some npm packages that are not compatible with it. So we need to support excluding those. For now a workaround is turning it off (https://docs.serverless-stack.com/constructs/Function#bundle). But that's the area that needs work.

Thanks for reply. I wondered if it is possible to migrate current Serverless app on Seed.run to SST? Or do I need to create new app?

Migrating is a little tricky because of the resources that'll get created. We are going to create a migration guide in the future. But for Seed, you can add a new service in your existing app that's an SST app. We do that here in this repo, https://github.com/AnomalyInnovations/serverless-stack-demo-api. There's a Serverless Framework service and an SST app in the same app. And this works in Seed.
