How much do I get with free tier? How many users may the site serve?

Hi @sonic frost. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

On the Convex free (Starter) tier, you get the following resource limits:

  • Database storage: 0.5 GiB included (additional storage is $0.22/month per GiB)
  • Database bandwidth: 1 GiB/month included (additional bandwidth is $0.22 per GiB)
  • File storage: 1 GiB included (additional storage is $0.033/month per GiB)
  • File bandwidth: 1 GiB/month included (additional bandwidth is $0.33 per GiB)
  • Function calls: 1,000,000 per month included (additional calls are $2.20 per 1,000,000)
  • Concurrent function executions: Up to 16 concurrent queries and mutations, 64 V8/Node actions, and 16 HTTP actions
  • Projects per team: 20
  • Developers per team: 1-6

There is no explicit limit on the number of users your site may serve. The practical limit depends on your usage patterns—specifically, how much bandwidth and how many function calls your users generate. For example, a few thousand concurrent users is feasible if your queries and updates are efficient and not overly frequent. Convex does not explicitly limit the number of concurrent connections or subscriptions, but you should monitor your bandwidth and function call usage to stay within the free tier limits. If you expect high activity (e.g., frequent real-time updates), you may hit these limits sooner and need to upgrade or optimize your usage patternsProduction Limits Concurrent Subscriptions.

You can track your usage and see daily breakdowns in the Convex dashboardDashboard Usage.

If you need more resources or expect higher usage, you can consider upgrading to a paid plan, which offers significantly higher limits and scalability.
