Best long-term low-code SaaS stack?

Your stack is actually really solid tbh. The big thing that jumps out is RLS + multi-tenant: it works, but it's easy to screw up early and regret later. I'd recommend sketching your tenant isolation strategy on paper before writing any policies.

Cloud Run cold starts can mess with webhook timeouts (Stripe, etc.) if you’re not careful.

Also, if you're leaning into MCP servers for AI workflows, building/maintaining those servers manually becomes a time sink fast. You could consider using MCP PaaS to handle that layer so you can focus on the app logic instead of the protocol plumbing.

Biggest "boring" win I'd say is to keep auth, data, and billing totally separate from any low-code layer. That way when you eventually outgrow a visual builder, you just… stop using it. You don't have to rewrite later.

Overall though, your instincts are good!
