Open-source automatic backend generation with PostgreSQL, REST APIs, real-time features, and enterprise-grade caching. Add our powerful UI management tool for just $9.99/year.
Everything You Need
A complete backend solution with powerful features built-in. No assembly required.
Essential building blocks for your backend
Schema Management
Create and modify database schemas on-the-fly with automatic migration support. Define relationships, validations, and watch your data models come alive instantly.
RESTful APIs
Auto-generated REST endpoints with 50+ filter operators, sorting, and pagination.
Authentication
JWT, OAuth providers, magic links, and granular role-based access control.
Real-time
WebSocket support with Socket.IO and horizontal scaling via Redis.
Powerful Features, Zero Setup
Enterprise-grade features built into the core. No plugins, no extra configuration.
Near raw query performance
Hybrid Cache System
Multi-layer caching architecture with In-Memory and Redis/Valkey support for system schemas to make near raw query performance possible. Automatic cache invalidation on data mutations ensures consistency while delivering sub-millisecond response times.
Scale to millions of requests
Horizontal Scaling
Built for stateless horizontal scaling with shared Redis cache state. Deploy behind any load balancer and scale your Node.js instances independently.
Location-aware queries
PostGIS Geospatial
Full PostGIS integration for geospatial queries. Calculate distances, find nearby points, check polygon intersections, and sort by proximity - all through the API.
Automatic search indexing
Full-Text Search
PostgreSQL full-text search with automatic GIN index creation. Get ranked search results with fuzzy matching and multi-field search capabilities.
MongoDB-style querying
Advanced JSON Filters
Powerful JSON-based filtering with nested conditions, logical operators, and relation traversal. Query across related tables with intuitive syntax.
Concurrent session control
Session Limiting
Control the number of concurrent sessions per user. Automatically revoke the oldest sessions when limits are exceeded, with full device tracking.
Real-time alerts
Notification System
Built-in notification service with real-time delivery, read status tracking, and filtering. Support for in-app, push, and email notifications.
On-the-fly transformation
Image Resizing
Transform images on-the-fly with URL parameters. Resize, crop, change format, and optimize quality. Results are automatically cached for fast delivery.

Why Not Free?Almost Free!
We could have made the Admin UI completely free. But here's a little secret about "free" software in 2025... it often doesn't end well. Let us explain why $9.99/year is actually the most honest deal you'll find.
Less than a coffee per month
At $0.83/month (yearly plan), you're paying less than that fancy latte you'll forget about in 10 minutes. But Baasix? It'll remember your schemas forever! ☕
No "Surprise! We're expensive now"
We've all seen it: free tool gets popular → venture capital arrives → suddenly it costs $99/month. We're staying indie and keeping prices human-friendly. 🛡️
Maintainers gotta eat too
Open source maintainers burning out is the #1 project killer. Your tiny contribution keeps us caffeinated, motivated, and shipping features instead of searching for "real jobs". 💪
Sustainable > Free-until-we-quit
Many free tools are one maintainer burnout away from becoming abandonware. We'd rather charge a coffee and stick around for decades than go free and ghost you. 👻
Real Talk: What $0.83/month gets you
Spoiler: It's probably the best ROI in your tech stack
Cheaper than a mobile game that you'll delete in a week
Less than 1/10th of a pizza delivery
Half the price of that streaming service you forgot to cancel
Way cheaper than that cloud service that charges per API call
Our Promise
Your small contribution = Long-term development, regular updates, and a tool that won't suddenly disappear or become unaffordable.
P.S. If $9.99/year is genuinely too much for you, reach out to us. We've got special pricing for students, indie hackers bootstrapping their dreams, and developers from regions where this amount means more. We're here to help, not to gatekeep.
Frequently Asked Questions
Everything you need to know about Baasix
Why is the pricing so affordable?
We believe in sustainable, fair pricing. Our goal isn't to maximize profits—it's to keep development going and maintain the codebase for the community.
We're already profitable through our enterprise client projects where we use Baasix extensively. The license fees help us dedicate time to open-source development, bug fixes, security updates, and new features that benefit everyone.
Think of it as supporting sustainable open-source development rather than paying for software access.
