* * *

## Runtime limits[#](#runtime-limits)

    *   Free plan: 150s
    *   Paid plans: 400s
*   Maximum CPU Time: 2s (Amount of actual time spent on the CPU per request - does not include async I/O.)
*   Request idle timeout: 150s (If an Edge Function doesn't send a response before the timeout, 504 Gateway Timeout will be returned)

## Platform limits[#](#platform-limits)

*   Maximum Function Size: 20MB (After bundling using CLI)
*   Maximum no. of Functions per project:
    *   Free: 100
    *   Pro: 500
    *   Team: 1000
    *   Enterprise: Unlimited
*   Maximum log message length: 10,000 characters
*   Log event threshold: 100 events per 10 seconds
*   Recursive/Nested Function Calling: ~5000 requests per minute [more details](../recursive-functions/index.md)

### Secrets[#](#secrets)

*   Maximum number of secrets per project: **100**
*   Secret name length: up to **256** characters
*   Maximum secret size: **48 KiB** (**24,576** characters)
*   Names must NOT start with the prefix `SUPABASE_` (this prefix is reserved).

## Other limits & restrictions[#](#other-limits--restrictions)

*   Outgoing connections to ports `25` and `587` are not allowed.
*   Serving of HTML content is only supported with [custom domains](/docs/reference/cli/supabase-domains) (Otherwise `GET` requests that return `text/html` will be rewritten to `text/plain`).
*   Web Worker API (or Node `vm` API) are not available.
*   Static files cannot be deployed using the API flag. You need to build them with [Docker on the CLI](../quickstart/index.md#step-6-deploy-to-production).
*   Node Libraries that require multithreading are not supported. Examples: [`libvips`](https://github.com/libvips/libvips), [sharp](https://github.com/lovell/sharp).
