Right now, It's is only standalone PWA. I have plans to integrate it with NostrNet, incorporating serverless auto-backup. It's open source, so anyone interested in integration is more than welcome. I can also assist in the integration process. Every client should at least consider doing it for the follow and relay list; that will solve a significant problem.
