Two ways to run it

As it is

Host your app as it is

Your built app runs from your computer at a link you share. It keeps using the database and services it already has.

  • Your React app, unchanged
  • Your Supabase or Firebase project, still connected
  • A link that works while your computer is on
On Seamside

Move it onto Seamside

Ask Claude or Cursor to swap the hosted parts for Seamside’s own. Then nothing depends on a subscription.

  • Sign-in, and who can view or edit
  • Its data saved on your computer
  • Its server code running on your computer too
  • No hosted service left to pay for
Move this app onto Seamside. Use Seamside tables instead of Supabase, and Seamside sign-in instead of Supabase Auth.

Questions

What about my Supabase data?

It stays in your Supabase project and the app keeps using it. If you’d rather not depend on it, ask an agent to move it onto Seamside tables.

Will my app work as it is?

Most will. Your app runs from your computer and keeps using the database and sign-in it already has. If you’d rather not depend on those services, ask Claude or Cursor to move it onto Seamside’s own tables and sign-in.

Does my computer need to stay on?

Yes, for people to open what you share. When it’s off, visitors see that it’s offline. A spare computer can keep things up all the time.

Is it really free?

Yes. We don’t host your things, so there’s nothing to charge for. Seamside Plus adds extras for $9 a month, and what you can do today stays free.

Does Seamside use AI?

Seamside itself doesn’t need AI. It hosts and shares what you make, however you made it.
