// free plan limits

Which free plan limit will your app hit first?

A paused database, a read-only table, a "Site not available" page: free plan limits break apps in ways that look like bugs. Answer four questions and see which limit comes first for your app, then what it looks like when it does.

Your answers stay in this page. Nothing is sent or stored.

About your app

Your app runs on
How many people use it on a typical day?
How much data does the database hold, or will soon?
Do people upload files?
How often does it go unused?

The limits your app meets first

A rough estimate from your answers, highest first. The assumptions are below.

Also true whatever your answers

  • Netlify Each production deploy uses 15 credits. Deploys spend the same credits as traffic, so a day of many deploys can pause the sites. Deploy previews, branch deploys and failed deploys use none.
  • Vercel Personal, non-commercial use only. Taking payments, showing ads or being paid to build the site needs the Pro plan.
  • Vercel 300 seconds per function call. A slower call, like a long AI request, stops with 504 FUNCTION_INVOCATION_TIMEOUT.
  • Firebase No Cloud Functions on Spark. Server code in Cloud Functions needs the Blaze plan.
  • Supabase 2 active projects. A third project cannot run until you pause one. Paused projects do not count.
How the estimate works
  • Each daily user makes 1 visit a day, and monthly users are 4 times the daily users.
  • A visit downloads 1 MB from the host on average and makes 20 requests, 5 of them to server functions.
  • A visit reads 200 KB from the database, or makes 30 Firestore reads and 3 writes.
  • Photos and documents means about 500 MB in all with files up to 8 MB; video or large files, about 5,000 MB with files up to 200 MB.
  • Each answer counts above the middle of its range, so the ranking warns early. Your own usage page is the real number.

The limits, service by service

Supabase Free plan

Pricing page

  • Paused after 7 days with no activity

    When you hit it: Every database and sign-in call fails because the whole project is paused. Restore it from the dashboard with one click; that stays possible for a year.

    Source

  • 500 MB database size

    When you hit it: The database turns read-only: reads work, but saves fail with "cannot execute INSERT in a read-only transaction".

    When you hit it: Same as data transfer: sustained use past it can pause the deployment.

    When you hit it: Further deploys are refused until the day has passed.

    Source

  • Runtime logs kept for 1 hour

Netlify Free plan

Pricing page

  • 300 credits a month, hard limit
