The Verdict
Notion Sites is built for knowledge bases and documentation sites, with a focus on page-publishing and custom-domains. Supabase targets developers and startups and leads with postgres-database and authentication.
On pricing, Notion Sites is the clear winner for budget-conscious users — starting at $10/mo compared to $25/mo for Supabase. That $15/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Supabase edges out on user ratings (4.7 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Supabase offers broader built-in capabilities (7 features vs 6), while Notion Sites takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Supabase has a slight overall edge — but if publish websites directly from notion pages matters most to you, Notion Sites may still be the right call.
