What does Supabase cost in 2026? Pricing tiers and plans explained

Pricing Overview

Supabase is an open-source Firebase alternative built on PostgreSQL. The platform provides a managed database, authentication, edge functions, real-time subscriptions, storage, and vector embeddings. Pricing is based on database size, bandwidth, and monthly active users (MAUs) across four tiers. The open-source nature allows self-hosting for organizations that need full infrastructure control.

Supabase Pricing Tiers (as of March 2026)

What Each Tier Includes

Free

The free tier provides a PostgreSQL database with 500 MB storage, 50,000 monthly active users for authentication, 1 GB of file storage, 500 MB of bandwidth, and 2 projects. Edge functions are limited to 500,000 invocations per month. The free tier is generous for prototyping and small production projects. Projects on the free tier are paused after 1 week of inactivity.

Pro

The Pro tier at $25 per project per month increases the database to 8 GB, authentication to 100,000 MAUs, file storage to 100 GB, and bandwidth to 250 GB. Daily backups with 7-day retention are included. Pay-as-you-go pricing applies for usage beyond the included allocations. This tier is designed for production applications with moderate traffic.

Team

The Team tier at $599 per month includes everything in Pro plus SOC2 compliance attestation, priority support with guaranteed response times, organization-level billing, and enhanced access controls. The database starts at 8 GB but can be expanded with pay-as-you-go pricing. This tier targets startups and mid-size companies with compliance requirements.

Enterprise

Enterprise pricing is negotiated for organizations needing dedicated infrastructure, custom SLA terms, dedicated support engineers, advanced security features (private networking, custom encryption), and custom data residency guarantees.

Pay-As-You-Go Overages (Pro and Team)

Hidden Costs and Considerations

• Per-project pricing: Supabase charges $25/month per project on the Pro tier. A microservices architecture with 5 separate Supabase projects costs $125/month. Organizations should consolidate into fewer projects where possible.
• Bandwidth costs at scale: Applications with heavy read traffic can accumulate significant bandwidth costs. A project serving 1 million API requests per day with 1 KB average response size generates approximately 30 GB of bandwidth per month — within Pro limits, but doubling traffic pushes into overage territory.
• Vector database add-on: Supabase supports pgvector for AI embeddings, included in the database. However, vector operations are compute-intensive and may require larger compute instances at additional cost.
• Realtime connections: The Realtime feature (websocket-based live data subscriptions) has concurrent connection limits that scale by tier. High-concurrency applications (live dashboards, collaborative tools) may need to upgrade tiers for connection capacity.

How Supabase Pricing Compares

Supabase's Pro tier at $25/month competes directly with Firebase's Blaze plan (pay-as-you-go, no fixed monthly fee but costs accumulate). For similar usage levels, Supabase is typically 30-50% less expensive than Firebase due to the fixed base price including generous allocations. PlanetScale (MySQL-based) starts at $39/month. Neon (serverless Postgres) starts at $19/month but with lower included storage. For teams that want a full backend-as-a-service (database + auth + storage + functions), Supabase provides the most complete package at the $25/month price point. Self-hosting Supabase is free but requires managing PostgreSQL, GoTrue (auth), and storage services independently.

Editor's Note: We deployed Supabase Pro ($25/month) for a SaaS startup building a project management tool. The application serves 3,200 monthly active users with real-time collaborative features. Monthly costs: $25 base + $4.50 database overage (10 GB) + $12 bandwidth (130 GB from heavy API usage) = $41.50/month. The team previously used Firebase at approximately $85/month for comparable usage. Migration from Firebase to Supabase took 3 weeks, primarily due to converting Firestore queries to SQL. The team valued Supabase's PostgreSQL foundation — standard SQL, foreign keys, and row-level security policies were significant improvements over Firebase's NoSQL model. The main limitation: Supabase Edge Functions have cold start latency of 200-500ms, which was noticeable for the first request after idle periods.
