Supabase is the default backend for the modern frontend stack and the pick for indie builders and startups. You get a real Postgres database (not a NoSQL approximation), plus auth, storage, realtime, edge functions, and pgvector, all in one workspace, all open source. The trade is real: at scale the Pro tier's $25/mo floor plus usage adds up, and you'll outgrow the managed surface for truly heavy workloads. For everything from prototype to series-A, Supabase is the pick.
- Real Postgres under the hood, full SQL, extensions, no NoSQL approximation
- Auth + storage + realtime + edge functions in one workspace
- pgvector built in, production AI / RAG without bolt-on infra
- Open source, self-hostable end-to-end if you outgrow the cloud
- ChatGPT app + Claude connector ship in 2026 for agent workflows
- $25/mo Pro floor plus usage tips fast above free-tier limits
- Free projects pause after 1 week of inactivity
- Heaviest workloads outgrow the managed surface eventually
- Vendor-coupled to Supabase's Postgres image and runtime
- Realtime + storage abstractions add their own learning curve
Supabase is an open-source Firebase alternative built on Postgres. It ships a managed Postgres database, authentication, file storage, realtime subscriptions, and edge functions in one workspace, and the whole stack is self-hostable if you outgrow the cloud or need to own the runtime.
Where it fits
Supabase is the default backend for indie builders, startups, and small teams shipping Next.js, SvelteKit, Nuxt, or any frontend that needs a real database, auth, and file storage without spinning up three different services. The wedge is the integrated workspace: one project, one dashboard, one set of credentials, one bill.
For AI applications, pgvector is built in, embeddings live next to relational data, queryable from the same SQL surface. For realtime use cases (chat, collaboration, dashboards), Postgres logical replication powers row-level subscriptions without bolt-on infrastructure.
Pricing in practice
Free includes 500 MB database, 5 GB egress, 50K MAU, and 1 GB file storage, but free projects pause after a week of inactivity. Pro is $25/month per organization with 8 GB disk, 250 GB egress, 100 GB storage, 100K MAU, and 7-day daily backups. Usage above included is billed: $0.125/GB disk, $0.09/GB egress, $0.021/GB storage. Team is $599/month with SOC2 + ISO 27001 + priority support. Enterprise is custom with BYOC and dedicated infra.
The hidden lever is the Pro floor: $25 is the start, not the ceiling. A modest app with a real database, file storage, and auth will land at $40-$80/month. Free covers prototypes; Pro is where production-shaped apps live.
How it compares
Neon, Serverless Postgres with instant branching and per-PR preview databases. Pick when you want raw Postgres with elastic compute and don’t need the auth/storage/realtime layer.
Convex, Reactive TypeScript backend with end-to-end type safety from schema to client. Pick when you want a TS-native backend with built-in reactivity and don’t need Postgres compatibility.
PostgreSQL, Self-managed Postgres on your own infrastructure. Pick when compliance, cost at scale, or operational control matters more than managed DX.
MongoDB, Document database for schemaless or semi-structured data. Pick when your data model is genuinely document-shaped and you’d be fighting relational constraints.
Latest news
Supabase published Multigres v0.1 alpha on 2026-06-04, an open-source “operating system for Postgres” that bundles connection pooling, generalized-consensus high availability on unmodified Postgres replication, and pgBackRest backup orchestration into a single control plane. The v0.1 cut ships a multigateway plus multipooler with context-aware pooling (no transaction or session mode choice) and replica- sourced full, incremental, and differential backups, but holds back the headline sharding feature for a later release. A hosted version on the Supabase platform is on the roadmap. Supabase also shipped the official ChatGPT app plus a Claude connector in May 2026, made database branching the default that month, and landed ISO 27001 certification in April 2026.

Supabase is acquiring Turso, and the per-agent database just got a Postgres landlord
Supabase is acquiring Turso, the team that rebuilt SQLite in Rust for millions of tiny databases. Both products continue unchanged for now, but the plan is clear: lightweight SQLite for agent tasks, Postgres when workloads grow.

16,000 Supabase apps are leaking user data, and the cause is how AI coding tools create tables
UpGuard found 16,326 Supabase databases exposing readable tables to the open web, most of them built by AI coding tools. The common thread is a default: row-level security is on when you use the dashboard, off when an agent writes the SQL.

16,000 Supabase apps are serving readable user data, and the common thread is Row Level Security that was never switched on
Security firm UpGuard found more than 16,000 Supabase-backed apps serving readable tables to anyone on the web, over half of them holding personal data. The root cause is Row Level Security left off on API-created tables, a default that AI coding agents rarely go back and fix.

Databricks acquires Electric, winds down its cloud, and keeps the local-first Postgres open source
Databricks has acquired Electric, the team behind PGlite and the Electric sync engine, and folded it into Neon. The open-source projects stay open, Electric Cloud is winding down, and the stated goal is giving AI agents their own local Postgres.
