The Quick Answer for Real Estate Agencies
Choose Supabase if you need a reliable, structured database for all your critical real estate data – like client profiles, property listings, and agent commission logs – alongside secure logins for agents and clients, and the flexibility to host your own systems. Choose Firebase if your main focus is building a mobile app for your agents to manage leads on the go or a real-time client communication portal, especially if you're already using Google services heavily. Choose PlanetScale if you're building a massive property listing website or a complex brokerage platform handling thousands of transactions and need a highly scalable MySQL database that allows your development team to test new features without downtime.
Side-by-Side Backend Breakdown for Brokerages
Supabase offers a generous free tier, usually enough for a small brokerage's custom CRM with hundreds of client profiles and active listings. Their $25/month Pro plan easily scales for multiple agents. It uses PostgreSQL, perfect for detailed property specs and relational data like client-property links. It includes secure authentication for agent portals, storage for property photos and legal documents, and real-time updates for internal agent dashboards. Firebase provides a free Spark plan for basic real-time notifications (e.g., new lead alerts to agents) and a pay-as-you-go Blaze plan for growing mobile apps. Its NoSQL Firestore database offers flexible data modeling for less structured info like chat logs but can be tricky for complex property data. It includes agent authentication, hosting for client portals, and integrates seamlessly with Google Maps for property locations. PlanetScale has a free hobby tier for testing new database features for your brokerage. The $39/month Scaler plan is for robust, high-traffic listing databases. It's MySQL-compatible, ideal for many real estate websites, and offers database branching – like Git for your property database – to safely test changes to your agent management system. Note: its lack of foreign key support means you'd manage relationships between properties and agents manually, which might increase complexity for strict data integrity like commission payouts.
When to Choose Supabase for Your Real Estate Firm
You want a robust, relational database (PostgreSQL) as the backbone for critical real estate data, including client CRM, detailed property listings (square footage, amenities, HOA fees), agent performance metrics, commission tracking, and transaction history. You need secure agent and client logins (auth), a place to store property photos, virtual tours, and legal documents (storage), and real-time updates for internal agent dashboards or custom client portals. You value owning your data and want the flexibility to export your entire client list, property database, or even self-host your backend if your brokerage grows large enough. You are building a custom client portal or an internal agent platform and need to ensure agents only see their own client data, or clients only see their own property inquiries, using Row Level Security for fine-grained access control.
When to Choose Firebase for Real Estate Mobile & Web
You are building a mobile app for your agents (iOS or Android) that needs to work offline and provide real-time updates on new leads, property status changes, or client messages. Your brokerage heavily uses Google Workspace (Gmail, Calendar, Drive) and you want deep integration with Google Maps for property locations or Google Analytics for your property listing website traffic. You are building real-time collaborative features for your brokerage, such as instant chat between agents and clients, live document editing for transaction paperwork, or real-time presence indicators on a lead assignment board. You are comfortable with the NoSQL data modeling tradeoffs for your specific use cases, prioritizing speed and flexibility for data like agent activity logs or client communication over strict relational integrity for complex property data.
When to Choose PlanetScale for Brokerage Scale
Your real estate application is already MySQL-based, or you specifically prefer MySQL, and you need a database that can scale horizontally without downtime to handle a massive volume of property listings or client inquiries. You want database branching – the ability to safely test schema changes for new features on your agent portal (e.g., a new lead assignment workflow or commission calculator) in a separate branch before merging it into your live production database. You are building a high-traffic property listing website or a comprehensive brokerage management system that needs to handle millions of property searches or agent data lookups per second with guaranteed performance.
The Verdict for Your Real Estate Tech Stack
For most independent real estate brokerages starting out and needing a robust system for client data, property listings, and agent management, Supabase is the strongest foundation. It gives you the structured data power of PostgreSQL combined with the convenience of Firebase-like auth and file storage, without locking your valuable client data into a single vendor. Firebase still shines for mobile-first agent tools, quick client communication features, and tightly integrating with Google's ecosystem. PlanetScale is best reserved for large brokerages or national real estate platforms with high-traffic listing sites and dedicated development teams who need advanced MySQL scaling and deployment tools. Crucially, avoid Firebase's NoSQL for your main property listing data or client CRM if relationships (e.g., clients linked to properties, properties linked to agents, agents linked to commissions) are complex; the query limitations and data integrity challenges can become painful as your brokerage grows.
How to Get Started with Your Brokerage Backend
To start with Supabase: Sign up at supabase.com. Create a new project, and your PostgreSQL database for your 'Real Estate CRM' or 'Property Listing Portal' will be ready in under a minute. Use the built-in table editor to easily create tables for 'Properties,' 'Clients,' 'Agents,' and 'Commissions,' or write SQL directly. Install the Supabase client library and connect your custom website or agent app. To start with Firebase: Create a project at firebase.google.com. Add the Firebase SDK to your agent mobile app or client communication portal. Use the Firestore rules editor to secure your client data and property information. To start with PlanetScale: Sign up at planetscale.com. Create a database for your high-traffic IDX feed or custom listing site. Create a development branch to safely push and test schema changes for new features, like a 'property showing scheduler,' before it goes live to your agents and clients.

FREQUENTLY ASKED QUESTIONS
Is Supabase production-ready?
Yes. Supabase is used in production by thousands of companies. The free tier has limitations (projects pause after 1 week of inactivity), but the $25/month Pro plan provides production-grade uptime SLAs.
Can I migrate from Firebase to Supabase?
Yes, but it requires data transformation — Firestore's document model does not map directly to relational tables. There are community migration scripts, but expect significant engineering work for a production Firebase app.
Does PlanetScale support foreign keys?
PlanetScale does not support foreign key constraints due to its sharding architecture. You can model relationships in your application layer, but if you rely heavily on database-level referential integrity, this is a real limitation to evaluate.
