Picking a backend as an indie hacker isn't a philosophical decision — it's a money and time decision. You've got a weekend, a half-baked idea, and zero budget for DevOps. Which one do you actually ship with?
I've built projects on all three. Here's what the comparison actually looks like when you're not reading a vendor's own docs.
The Real Pricing Breakdown (No Marketing Spin)
Firebase (Google) has a generous free tier — the Spark plan gives you 1GB Firestore storage, 50K reads/day, and 10GB bandwidth. Sounds great until you build something that people actually use. Pricing jumps fast once you hit Blaze (pay-as-you-go), and Firestore read costs at scale are genuinely painful. A moderately successful app can run you $50–$300/month before you've thought about it.
Supabase free tier gives you 500MB database storage, 2 projects, 50K monthly active users, and 5GB bandwidth. Their Pro plan is a flat $25/month per project, which is predictable and indie-hacker-friendly. If you value knowing what your bill will be, Supabase wins on pricing psychology alone.
PlanetScale recently restructured pricing aggressively. Their free tier was killed for new users in early 2024, and Hobby starts at $39/month. The Scaler plan runs $39–$599/month depending on row reads. For a solo builder, PlanetScale is genuinely hard to justify unless you're already scaling and care deeply about MySQL branching workflows.
Winner on pricing: Supabase — flat, predictable, generous free tier.
Developer Experience and What You Actually Ship Faster With
Firebase is JavaScript-native and has mature SDKs. If you're building a React or Next.js app, the DX is smooth until you start doing complex queries. NoSQL means you're denormalizing data constantly, and that gets ugly fast on anything with relationships.
Supabase gives you a real Postgres database. Real SQL. Real foreign keys. The dashboard is clean, the API auto-generates from your schema, and the auth system with Row Level Security is genuinely excellent. Edge Functions are solid. If you've used Postgres before, onboarding is 20 minutes.
PlanetScale is MySQL with a Git-like branching model for schema changes. That branching workflow is legitimately impressive for teams doing rapid iterations — you can test schema changes on a branch before merging to production. But it's overhead for a solo founder. You're not deploying migrations as a team of one the same way a 5-engineer startup is.
For building fast and solo, Supabase's combo of Postgres + Auth + Storage + Realtime in one dashboard is unmatched. Firebase is second for pure real-time features (think chat apps or collaborative tools).
Winner on DX for indie hackers: Supabase, Firebase second for real-time-heavy apps.
Where Each One Actually Shines (Honest Use Cases)
Use Firebase if you're building: a mobile app (iOS/Android SDKs are more mature), a real-time collaborative product, or you want Google infrastructure without thinking about it. Firebase Auth is still very good.
Use Supabase if you're building: a SaaS product with relational data, anything with roles and permissions, a side project you want to monetize, or you want to own your data long-term with open source backing.
Use PlanetScale if you're building: a product on a team, using an existing MySQL codebase, or you're at a stage where zero-downtime schema migrations are a real operational concern. For most indie hackers reading this, that's not your problem yet.
If you're pairing your backend with a frontend, Webflow is worth looking at for marketing sites and landing pages. It pairs well with Supabase as a headless CMS alternative. And if you're managing customer relationships from launch day, HubSpot has a genuinely free CRM tier that works well alongside any of these backends.
My Recommendation (And Why I'd Bet on It)
Start with Supabase. It's open source (you can self-host if you outgrow it), the pricing is predictable, and Postgres scales further than most indie projects ever reach. The auth system alone would cost you hours to build from scratch.
Before you even touch backend setup though — get your business fundamentals documented. LexProtocol has free AI tools including a business plan builder and email writer that can help you validate the idea before you write a single line of backend code. Ship the plan, then ship the product.
Firebase is a fine second choice. PlanetScale is for a different stage.
