The Quick Answer
Choose Supabase if you want a flexible backend for managing client profiles, recurring tasks, and invoicing with the ability to control your data. Choose Firebase if you need a quick-start mobile app where clients book tasks directly and get live updates (e.g., 'runner is 5 min away'). Choose PlanetScale if you're building a larger concierge agency with many runners and need a highly scalable MySQL database for complex dispatching and location tracking.
Side-by-Side Breakdown
Supabase offers a free tier for 2 projects and 500MB storage, enough for your first client app and an internal dashboard. The $25/month Pro plan is good when you have a dozen regular clients. It uses PostgreSQL, great for robust client records, task lists, and payment history. Firebase has a free Spark plan for basic apps, moving to pay-as-you-go Blaze as your client list grows. It uses NoSQL Firestore for real-time updates, ideal for quick client messages or runner location tracking. PlanetScale has a free hobby tier and a $39/month Scaler plan. It uses MySQL, which is suitable for very high-volume transaction processing, like thousands of task assignments per hour if you scale significantly. Its schema branching helps test new features like dynamic pricing without affecting live client data, but remember it lacks foreign key support.
When to Choose Supabase
You want a relational database (PostgreSQL) for detailed client data like medical instructions for seniors, specific grocery lists, or address books, and to link tasks to clients and invoices. You need auth, storage, and real-time features for a client portal where they log in, view upcoming tasks, and upload documents (like prescription details). Storage is useful for delivery photos or receipts. You value open-source and the ability to move your client list, task history, and billing data to your own server without hassle. You are building a web app and want Row Level Security (RLS) to ensure clients only see their own tasks and billing info, and runners only see tasks assigned to them, which is crucial for data privacy in a service business.
When to Choose Firebase
You are building a mobile app (iOS or Android) as the primary way clients interact, needing offline sync (runners can update status even with spotty cell service) and real-time updates (for a chat feature or live tracking a package delivery). You are deeply in Google Cloud and want integration with other Google services. You are building a real-time collaborative feature — like a chat between clients and runners, or live tracking of a package delivery. You accept the NoSQL data modeling tradeoffs, which work well if your tasks are mostly independent short-term requests without complex relationships, like many single-item grocery runs.
When to Choose PlanetScale
Your application is MySQL-based, and you prefer to stick with it for your client database and task records. You need a database that scales horizontally without downtime if you plan to grow into a large operation with hundreds of runners and thousands of daily tasks across multiple cities. You want database branching — the ability to test new features like a loyalty program for regular clients or a new dispatch algorithm without risking your live client data. You are building a high-traffic application where clients, runners, and dispatchers are constantly interacting and updating tasks, orders, and locations.
The Verdict
For most personal errand and concierge businesses, Supabase is the best starting point. It gives you a reliable structure for client data (PostgreSQL) plus tools for client logins and storing files (like scanned receipts) without locking you into one company. Firebase remains strong for simple, real-time mobile apps where clients just need to book a quick task and get live updates. Consider it if your core offering is a mobile booking experience for tasks like 'meal prep delivery' or 'garden watering.' PlanetScale is for larger agencies with MySQL expertise handling many runners and complex scheduling. Avoid Firebase's NoSQL if your data has relationships — like detailed client profiles, recurring service plans, or complex payment tracking — the query limitations can become painful as your business grows.
How to Get Started
Supabase: Sign up at supabase.com. Create a project. Use the table editor to set up tables for 'clients' (name, address, notes), 'tasks' (type, due date, runner assigned), and 'invoices'. Install the Supabase client library and connect your website or simple internal app. Firebase: Create a project at firebase.google.com. Add the Firebase SDK to your client-facing mobile app. Use the Firestore rules editor to secure who can see what task and client data. PlanetScale: Sign up at planetscale.com. Create a database for your operations. Create a development branch to test new fields for client preferences (e.g., 'preferred coffee brand'), and push your schema changes when ready.

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.
