The No-Code Database Question: Airtable vs Supabase vs Firebase | SaaSGyver
Every app needs a database, and if you're building with no-code or low-code tools, you've got three main options. Each has a sweet spot. Pick wrong and you'll be migrating in three months. Pick right and you won't think about it for years.
The Three Options Compared
| Feature | Airtable | Supabase | Firebase |
|---|---|---|---|
| Type | Spreadsheet-database hybrid | SQL database (Postgres) | NoSQL document store |
| Learning curve | Very easy | Medium | Medium |
| Best for | Small apps, prototypes, internal tools | SaaS products, apps that will grow | Mobile apps, real-time features |
| Free tier | 1,000 records per base | 500MB, 50K rows | 1GB storage, 50K reads/day |
| Scales to | Small-medium | Large | Large |
| Auth built in? | No | Yes | Yes |
When to Use Each
Airtable: You're building an internal tool, a prototype, or anything where the 1,000-record free limit isn't a problem. It's also perfect when non-technical team members need to directly edit data -- they already know how spreadsheets work. Pairs great with Softr or Glide for a frontend.
Supabase: You're building a real SaaS product that needs user authentication, row-level security, and room to grow. It's PostgreSQL under the hood, so if you ever outgrow Supabase, you can take your database with you. Best choice if you're using React/Next.js.
Firebase: You're building a mobile app or something that needs real-time data syncing (collaborative editing, live dashboards, chat). Google's ecosystem, which is great if you're already there and concerning if you're not.
The Migration Factor
This matters more than most people think. Airtable data is easy to export but hard to move to a "real" database because the structure is loose. Supabase is standard PostgreSQL -- migrating away is straightforward. Firebase uses a proprietary data model that makes migration painful.
If there's any chance your app will outgrow its first database, start with Supabase. You'll thank yourself later.
Quick Takeaway
Airtable for quick prototypes and internal tools. Supabase for SaaS products you plan to grow. Firebase for real-time mobile apps. When in doubt, go with Supabase -- it's the most flexible option with the cleanest migration path.
