We’d love for you to have unlimited joy building on Convex but engineering practicalities dictate a few limits. This page outlines current limits in the Convex ecosystem.

Many of these limits will become more permissive over time. Please get in touch if any are prohibitive for your application.

Limits are applied per team unless stated otherwise.


$25/member per month


Storage0.5 GiB50 GiB included
$0.20/month per additional GiB
Includes database rows and indexes but not files or snapshots.
Bandwidth1 GiB/month50 GiB/month included

  • Table and index names must be valid identifiers and cannot start with an underscore.


Applied per document and to any nested Object unless stated otherwise.

Execution time and scheduling

Query/mutation execution time1 secondLimit applies only to user code and doesn’t include database operations.
Action execution time10 minutes
Scheduled functions1000The number of other functions a single mutation can schedule.
Total size of scheduled functions' arguments8 MiBApplies only to mutations.
Concurrent IO operations per function1000The number of IO operations a single function can perform, e.g., a database operation, or a fetch request in an action.

If any of these limits don't work for you, let us know!

Please see our plans and pricing page for resource limits. After these limits are hit on a free plan, new mutations that attempt to commit more insertions or updates may fail. Paid plans have no hard resource limits - they can scale to billions of documents and TBs of storage.
