Pocketbase vs Supabase — The Underdog vs The Titan

Pocketbase is a lightweight, open-source backend for small projects; Supabase is a full-featured, scalable Firebase alternative. Pick: Pocketbase for simplicity, Supabase for production.

The Core Divide: Embedded vs Cloud-First

Pocketbase is a single Go binary you run locally or on a server—it's an embedded database with a built-in admin UI and real-time capabilities, ideal for small apps or MVPs. Supabase is a cloud-hosted platform with PostgreSQL at its core, offering auth, storage, and edge functions—think of it as an open-source Firebase. If you want control without DevOps, Pocketbase; if you need a managed service with scaling, Supabase.

Where Pocketbase Dominates: Zero Friction

Pocketbase shines with instant setup—download the binary, run it, and you're done. It includes file storage, real-time subscriptions, and an admin dashboard out of the box, all for free (self-hosted). For solo developers or small teams building tools like internal dashboards or hobby projects, it eliminates complexity. Its SQLite backend keeps things simple, though it limits concurrency to about 100 concurrent connections—fine for most non-enterprise use.

Where Supabase Holds Its Own: Scale and Ecosystem

Supabase leverages PostgreSQL, supporting unlimited connections and ACID compliance, making it suitable for production apps with high traffic. It offers built-in authentication (OAuth, magic links), object storage with CDN, and serverless functions via Edge Functions. The free tier includes 500MB database and 1GB storage, but costs scale with usage (e.g., $25/month for 8GB database). If you're building a SaaS or mobile app needing robust features, Supabase's ecosystem is compelling.

Gotchas and Switching Costs

Pocketbase's SQLite backend isn't built for horizontal scaling—you can't easily shard or replicate data, so migrating later might require a rewrite. Supabase, while scalable, can get expensive quickly (e.g., $25/month for 8GB database, plus bandwidth charges). Also, Supabase's reliance on PostgreSQL means a steeper learning curve if you're not familiar with SQL. Pocketbase's simplicity is a double-edged sword: great for starters, limiting for growth.

Practical Recommendation: Match Your Stage

Use Pocketbase if you're prototyping, building a personal project, or need a backend for a small team tool—its zero cost and ease trump features. Use Supabase if you're launching a public app, expect rapid growth, or need advanced auth and storage—pay for scalability. For larger enterprises, consider Firebase or AWS Amplify as alternatives with more integrations.

Quick Comparison

Factor	Pocketbase	Supabase
Pricing	Free (self-hosted), no limits	Free tier: 500MB DB, 1GB storage; paid from $25/month
Database	SQLite, ~100 concurrent connections	PostgreSQL, unlimited connections
Real-time	Built-in via WebSockets	Built-in via PostgreSQL replication
Authentication	Basic email/password, OAuth2 via plugins	Full-featured (OAuth, magic links, SSO)
File Storage	Built-in, local or S3-compatible	Object storage with CDN
Setup Time	Minutes (single binary)	Hours (cloud config, migrations)
Scalability	Limited to single server	Horizontal scaling via PostgreSQL
Admin UI	Included, no-code friendly	Table editor via dashboard

The Verdict

Use Pocketbase if: You're a solo dev building a prototype, internal tool, or small app with minimal budget and need quick setup.

Use Supabase if: You're launching a production app with potential for high traffic, require advanced auth, or prefer a managed cloud service.

Consider: Firebase for more third-party integrations or AWS Amplify for deeper AWS ecosystem ties.

The Bottom Line

Pocketbase wins

Pocketbase wins for indie devs and prototypes with its zero-cost, self-hosted simplicity and instant setup. Supabase is overkill unless you need enterprise features or massive scale.
