What We Actually Use

In our experience, we lean towards Supabase for its robust SQL features and straightforward pricing.

For indie hackers and solo founders in 2026, the choice between Supabase and Firebase boils down to your specific project needs. If you value SQL database management, go with Supabase. If you prioritize real-time data capabilities, Firebase might be the right fit, but be wary of potential costs.

As you embark on your next project, consider your database needs carefully. Start with Supabase for its simplicity and cost-effectiveness, and only explore Firebase if your use case demands it.
