Supabase

Open-source Postgres development platform that bundles a managed database, authentication, instant APIs, Edge Functions, real-time subscriptions, object storage, and vector embeddings. Projects start with a dedicated Postgres instance, the world's most trusted relational database, with built-in Row Level Security that ties directly into auth.

Trusted by fast-growing companies for web, mobile, and AI applications. Differentiates by being fully open source and self-hostable: developers can inspect, contribute, and run the stack locally or on their own infra without vendor lock-in. Compared to Firebase, it delivers SQL and relational semantics instead of NoSQL. SDKs span React, Next.js, Vue, Nuxt, SvelteKit, Flutter, Kotlin, and more.

Key capabilities:

• Full Postgres database with table editor, SQL editor, materialized views, partitions
• Authentication with Row Level Security and custom domains
• Edge Functions for serverless custom logic without managing infra
• Realtime subscriptions for multiplayer and collaborative experiences
• Object storage for files, images, and media
• Vector embeddings integration for ML and semantic search
• Instant REST and GraphQL APIs generated from the schema
• Local development via Supabase CLI, runs with Docker

Build MVPs in days by wiring auth and a few tables, or scale to production with built-in security and performance advisors. Suits SaaS backends, internal tools, AI apps with vector search, and real-time dashboards. Integrates with popular frameworks and ships MCP tooling for AI-assisted schema and RLS design.
