Normal product backend when zero-cost purity is less important than reliability.

Gotchas

  • 500 MB database size

    Each free project is limited to 500 MB of Postgres database storage, resetting if data is deleted but not auto-expanding.

  • 5 GB egress per month

    Free tier includes 5 GB of database/API egress per month; requests continue but overages are blocked without upgrade.

  • 50,000 monthly active users

    Auth is capped at 50,000 MAUs per month on the free tier; exceeding this requires upgrading to Pro.

  • 1 GB file storage

    Object/file storage is limited to 1 GB total on the free plan.

  • 500,000 Edge Function invocations/month

    Edge Functions are capped at 500,000 invocations per month on the free tier.

  • 2M Realtime messages/month

    Realtime channel messages are limited to 2 million per month; concurrent peak connections capped at 200.

  • Project paused after 1 week of inactivity

    Free projects are automatically paused after 7 consecutive days of inactivity and must be manually resumed, causing downtime.

  • Max 2 active projects

    Free accounts may only have 2 active projects simultaneously across the entire account.

  • No automatic backups

    Automatic daily backups and point-in-time recovery are not available on the free tier; data loss on accidental deletion is permanent.

  • No dedicated compute (shared CPU/RAM)

    Free projects run on shared CPU with only 500 MB RAM; dedicated compute add-ons are not available on the free plan.

  • 1-day log retention

    API and database logs are retained for only 1 day on the free tier, making debugging production issues difficult.

  • No SSO, SAML 2.0, or advanced auth

    Enterprise auth features including SAML 2.0 SSO, leaked password protection, session timeouts, and advanced MFA are not available on the free tier.

  • Basic CDN only (no Smart CDN)

    Storage egress uses a basic CDN on the free plan; the Smart CDN with better cache hit rates is a paid feature.

  • No image transformations

    On-the-fly image resizing and transformation via Supabase Storage is not available on the free tier.

  • 50 MB max file upload size

    Individual file uploads are capped at 50 MB on the free plan, versus 500 GB on Pro.

  • No branching support

    Database branching (preview environments per Git branch) is a paid-only feature not available on the free tier.

  • Community support only

    Free tier users only have access to community support forums; email support and SLAs require the Pro plan or higher.

  • Shared compute, 60 direct DB connections

    Free projects use a shared Micro-equivalent instance with a hard limit of 60 direct Postgres connections and 200 via the connection pooler.
