What Is Supabase?
Supabase is the open-source Firebase alternative that gives developers a complete backend in minutes — managed PostgreSQL database, authentication, real-time subscriptions, file storage, edge functions, and vector embeddings. Used by over 700,000 developers in 2026, Supabase has become the default backend platform for startups building with React, Next.js, Flutter, and Swift who want production-grade infrastructure without managing servers.
Unlike Firebase (proprietary, NoSQL, Google lock-in), Supabase is built on PostgreSQL — the most trusted relational database in the world. Your data lives in standard Postgres, queryable with standard SQL, exportable at any time. No vendor lock-in by design.
Key Features
- PostgreSQL — Not a Proprietary Database
- Authentication — Production-Ready in 5 Minutes
- Real-Time Subscriptions
- Edge Functions — Serverless at the Edge
- Vector Embeddings — AI-Native Database
What Is MongoDB?
MongoDB is the world's most popular NoSQL database, used by over 46,000 customers ranging from early-stage startups to Fortune 500 companies. At its core, MongoDB stores data as flexible JSON-like documents rather than rigid rows and columns — a design choice that makes it uniquely suited to the way modern applications are built.
Where relational databases like PostgreSQL require you to define a fixed schema upfront, MongoDB lets your data structure evolve as your product evolves. Add a new field to your user objects? It's there immediately, with no migration script required. Building a feature that needs nested arrays or variable-length data? MongoDB handles it natively without the complexity of joining multiple tables.
MongoDB Atlas is the cloud-hosted version of MongoDB — a fully managed database service running on AWS, Google Cloud, and Azure across 100+ global regions. In 2026, MongoDB Atlas has become the default choice for startups building applications with flexible, evolving data requirements, particularly those working on SaaS products, mobile apps, real-time features, and AI/ML data pipelines.
Key Features
- Flexible Document Model — Build Without Schema Migrations
- Atlas Serverless — Zero Infrastructure Cost at Zero Traffic
- Atlas Vector Search — Build AI Features on Your Existing Data
- Global Clusters — Data Close to Your Users
- Automated Backups and Point-in-Time Recovery

Can I combine this with other discounts?
The $500 MongoDB Startup credits cannot be stacked with other promotional Atlas credits. However, you can use your MongoDB Atlas database alongside any other startup deal — MongoDB works with any cloud provider and application stack.
