# Fluxbase

[![CI](https://github.com/fluxbase-eu/fluxbase/actions/workflows/ci.yml/badge.svg)](https://github.com/fluxbase-eu/fluxbase/actions/workflows/ci.yml)

> **Beta Software**: Fluxbase is currently in beta. While we're working hard to stabilize the API and features, you may encounter breaking changes between versions. We welcome feedback and contributions!

Run `make test-full` to validate all critical flows.

A lightweight, single-binary Backend-as-a-Service (BaaS) alternative to Supabase. Fluxbase provides essential backend services including auto-generated REST APIs, authentication, realtime subscriptions, file storage, and edge functions - all in a single Go binary with PostgreSQL as the only dependency.

## Features

### Core Services

- **PostgREST-compatible REST API**: Auto-generates CRUD endpoints from your PostgreSQL schema

- **GraphQL API**: Full GraphQL support with configurable depth/complexity limits

- **Authentication**: Email/password, magic links, OAuth2 (Google, GitHub, Microsoft, etc.), OIDC, SAML SSO, MFA/TOTP

- **Realtime Subscriptions**: WebSocket-based live data updates using PostgreSQL LISTEN/NOTIFY

- **Storage**: File upload/download with access policies (local filesystem or S3), image transformations

- **Edge Functions**: JavaScript/TypeScript function execution with Deno runtime

- **Background Jobs**: Long-running tasks with progress tracking, retry logic, cron scheduling

- **RPC/Procedures**: SQL-based serverless procedures with scheduling and RBAC

- **Webhooks**: Event-driven webhook delivery for database changes with retries and HMAC signing

- **Vector Search**: pgvector-powered semantic search with automatic embeddings

- **MCP Server**: Model Context Protocol for AI assistant integration

### Key Highlights

- Single binary or container deployment

- PostgreSQL as the only external dependency

- Automatic REST endpoint generation

- Row Level Security (RLS) support

- TypeScript SDK

- Database branching for dev/test environments

- Built-in observability (Prometheus metrics, OpenTelemetry tracing)

- Horizontal scaling with leader election
