||
## Runtime limits
|
||
|
||
- Maximum Memory: 256MB
|
||
- Maximum Duration (Wall clock limit):
|
||
This is the duration an Edge Function worker will stay active. During this period, a worker can serve multiple requests or process background tasks.
|
||
- 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
|
||
|
||
- Maximum Function Size: 20MB (bundled locally via the CLI) or 5MB (bundled server-side, e.g. via the Management API or Dashboard)
|
||
- Maximum no. of Functions per project:
|
||
- Free: 100
|
||
- Pro: 1000
|
||
- Team: 2000
|
||
- Enterprise: Unlimited
|
||
- Maximum log message length: 10,000 characters
|
||
- Log event threshold: 100 events per 10 seconds
|
||
- Recursive/Nested Function Calling: 30 requests per trace, within a 60-second window [more details](/docs/guides/functions/recursive-functions)
|
||
|
||
### 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).
|
||
- Need more than 100 secrets? [Bundle secrets into a JSON value](/docs/guides/troubleshooting/working-around-the-edge-function-secrets-limit).
|
||
|
||
## 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](/docs/guides/functions/quickstart#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).
