📝 About Supabase
Supabase has become the default backend for a huge share of modern web and AI applications. Built on plain PostgreSQL, it instantly exposes your database through auto-generated REST and GraphQL APIs, adds authentication, row-level security, file storage, and realtime subscriptions, and lets you self-host the whole stack whenever you want out.
Unlike document-store competitors, Supabase gives you actual SQL, joins, and migrations, which is why teams with relational data keep choosing it. Realtime channels make collaborative features nearly trivial, and tight integrations with frameworks like Next.js and AI app builders have made it the go-to pairing for 2026’s wave of generated applications.
The free tier is generous enough for serious side projects, and usage-based pricing scales smoothly from there. If you are starting a new product and want a backend you will not outgrow or migrate away from, Supabase is the strongest 2026 default.
