Supabase Pricing in 2026: Every Tier, Hidden Costs, and When Firebase or Neon Wins

TL;DR: Supabase Pro at $25/month is the sweet spot for most B2B SaaS apps under 100K MAUs. The pricing is more predictable than Firebase (resource-based, not per-operation) and cheaper than self-hosted Postgres once you factor in auth, storage, and realtime. The trap most teams fall into: bandwidth overage at $0.09/GB and compute upgrades that double the bill before you notice. Below: every plan, four hidden costs, the compute add-on ladder, and the cost comparison with Firebase and Neon at three real workload sizes.

What you actually pay

Supabase has four tiers. Pricing is in USD, billed monthly with no annual discount.

The published Pro and Team tiers include the same resource limits. The $574/month premium for Team buys SOC2 + ISO 27001 compliance, 14-day backups instead of 7-day, 28-day log retention instead of 7-day, and priority email support with SLAs. For non-regulated teams, Pro is the rational choice.

The compute add-on is the line item nobody plans for

The $25 Pro base includes one Micro compute instance (2-core ARM, 1 GB RAM, 60 connections). The Free tier also runs on Micro but shared. For most apps under 10K MAUs, Micro is fine. Past that, you upgrade compute and the bill changes shape fast.

A team running Pro with a Large compute pays $25 + $100 (Large minus the $10 Micro credit) = $125/month for the database alone. Bandwidth overages, additional projects, and Point-in-Time Recovery add to that. A common B2B SaaS at 30K MAUs typically lands at $150-300/month all-in on Pro.

Four hidden costs the pricing page understates

1. Egress overage at $0.09/GB. The 250 GB included on Pro sounds generous until you serve images, file downloads, or chatty API responses. A SaaS app at 10K MAUs serving 1 MB of data per user per day burns 300 GB/month, putting you $4.50/month over base. At 100K MAUs and the same pattern, that's $45/month overage. Cached egress is cheaper at $0.03/GB; configuring Cloudflare or Vercel Edge in front cuts this dramatically.

2. Authentication MAU overage at $0.00325/MAU. The 100K MAU cap on Pro feels like a lot until you build something consumer-adjacent. Past 100K, each additional MAU is $0.00325. At 200K MAUs you owe $325 in MAU overage alone, pushing the monthly bill north of $400 even before compute or storage.

3. Branching costs $0.013 per branch per hour. Database branching for staging or PR previews is billed continuously. A branch left running for a month costs $9.60. Most teams discover this only when seeing 20 stale branches on the bill. Set branch cleanup automation from day one.

4. Compute is per-project, not per-account. Every Supabase project gets its own compute instance, billed separately. Teams running staging + production + dev as three projects pay 3x compute (or run staging and dev on Micro to keep the bill sane). Plan project topology before scaling.

Supabase vs Firebase at three workload sizes

The fundamental difference: Supabase charges for resources (database size, MAUs, bandwidth), Firebase charges for operations (per read, per write, per function invocation).

For apps with predictable load, Supabase is dramatically cheaper. For apps with bursty traffic or inefficient queries, Firebase can spike unexpectedly.

The 30-50% Supabase advantage at mid-scale is real. The reason: Firebase's per-operation pricing punishes apps that haven't optimized query patterns, while Supabase's resource-based pricing rewards efficient schema design.

Firebase still wins on three things: tighter Google integration (especially Analytics + Cloud Functions), better real-time sync at massive scale, and no compute decisions to make. For consumer apps where engineers want to ship without thinking about Postgres, Firebase remains competitive despite the higher bill.

Supabase vs Neon at three workload sizes

Both are Postgres-based, both target developers, both have generous free tiers. The mechanical difference: Neon auto-suspends compute after 5 minutes of inactivity (scale-to-zero), while Supabase compute runs continuously.

Neon wins for bursty workloads, internal tools, and side projects where the database sits idle most of the day. Supabase wins for apps that need bundled auth, storage, realtime, and edge functions in one platform.

The other consideration: Supabase ships a full BaaS (auth, storage, realtime, edge functions). Neon is database-only. Teams that need auth and storage have to bring their own (Clerk, Auth0, Cloudflare R2), and the assembled cost often eats Neon's price advantage.

Which plan you actually need

Solo founders, MVPs, side projects: Free tier on Micro compute. The 500 MB database and 50K MAU limits handle most early-stage products. Watch the inactive-project pause: if your project gets no requests for 7 days, it's paused and a single ping wakes it.

Early-stage startups, 0-25K MAUs: Pro at $25/month with default Micro compute. Plan to upgrade to Small ($15) or Medium ($60) when you cross 5K concurrent users or notice query latency spikes.

Scaling B2B SaaS, 25K-100K MAUs: Pro with Large or XL compute ($110-210). Budget $150-300/month all-in. The Team plan's $599/month is only worth it for SOC2-required customers.

Compliance-heavy or regulated: Team at $599/month. The SOC2 + ISO 27001 included is the value driver, not the marginal features.

Enterprise / very high scale: Enterprise tier. Pricing negotiates on compute, MAU caps, and BYO cloud (run Supabase in your own AWS/GCP account). Teams above 500K MAUs typically save 20-30% versus the published Pro pricing extrapolated to their scale.

Skip Supabase if...

The pricing model is wrong for two cases. Skip Supabase if your workload is genuinely bursty and idle 80%+ of the time (Neon's scale-to-zero saves 60-80% on those patterns). Skip Supabase if you need write-heavy workloads at scale where Postgres replication becomes a bottleneck (DynamoDB or PlanetScale handle this better).

For everything else, especially Postgres-first apps, consumer SaaS at moderate scale, and teams that want bundled auth + storage + realtime, Supabase's pricing is one of the most predictable in the database market.

FAQ

Does Supabase Pro auto-scale my compute? No. You pick a compute size and it runs continuously at that level. To handle traffic spikes, either over-provision or add read replicas. Auto-scale exists only on Enterprise.

What happens when I exceed the included quotas on Pro? Overage rates apply automatically: $0.09/GB egress, $0.125/GB disk, $0.00325 per extra MAU, $2 per million Edge Function invocations beyond 2M. No service interruption; the bill just grows.

Can I move from Supabase to self-hosted Postgres later? Yes. Supabase is built on standard Postgres, so pg_dump exports cleanly. The harder part is migrating off Supabase's auth, storage, and realtime, which require building or buying alternatives (Clerk + S3 + WebSocket service). Budget two weeks of engineering work for a full migration.

Are there discounts for annual prepayment? No, Supabase bills monthly with no annual discount on Pro or Team. Enterprise contracts are negotiable.

Does the Free tier expose my data publicly? No. Row-level security (RLS) policies apply identically on Free and Pro. The free tier's only data risk is the 7-day inactivity pause, which doesn't delete data but does make the project unreachable until re-enabled.

Bottom line

For most B2B SaaS teams making the Supabase vs Firebase vs Neon decision in 2026, Supabase Pro at $25/month plus the right compute add-on lands between $50-300/month and is dramatically more predictable than Firebase at the same scale. The hidden costs to watch are egress overage and unplanned compute upgrades, both of which surface on the bill before they surface in monitoring. Audit egress patterns monthly, plan compute upgrades against load tests, and the math always favors Supabase over Firebase at mid-scale.
