Discourse ships with 3 different global rate limits that can be configured by site admins. ## Global per-ip rate limits These limits apply to every unique IP address that hits the Discourse application. (files that are served directly from the filesystem or the CDN are excluded) By default this rate limit is **enabled** , you may disable it or set it to a reporting mode. `DISCOURSE_MAX_REQS_PER_IP_MODE` : default `block`, this rate limit applies out of the box. (other options are `warn`, `warn+block`, and `none`) `DISCOURSE_MAX_REQS_PER_IP_PER_MINUTE`: number of requests per IP per minute (default is 200) `DISCOURSE_MAX_REQS_PER_IP_PER_10_SECONDS`: number of requests per IP per 10 seconds (default is 50) `DISCOURSE_MAX_ASSET_REQS_PER_IP_PER_10_SECONDS`: number of asset (avatars/css) requests per IP per 10 seconds (default is 200) `DISCOURSE_MAX_REQS_RATE_LIMIT_ON_PRIVATE`: should the rate limit apply to private IPs accessing Discourse? default is false. `DISCOURSE_SKIP_PER_IP_RATE_LIMIT_TRUST_LEVEL`: use per user rate limits vs IP rate limits for users with this trust level or more (default 1) `DISCOURSE_MAX_REQS_PER_IP_EXCEPTIONS`: a space-separated list of IP addresses or CIDR blocks to exempt from per-IP rate limiting. For example: `14.15.16.32/27 216.148.1.2` ## User API rate limits The mobile applications acquire a user API key per device to access Discourse on behalf of a user (using an open protocol). These API keys are very tightly limited. `DISCOURSE_MAX_USER_API_REQS_PER_MINUTE`: default 20 `DISCOURSE_MAX_USER_API_REQS_PER_DAY`: default 2880 ## Admin API rate limits The administrative API keys can be generated via the `yoursite.com/admin/api/keys` page. These keys can operate on behalf of users, but require administrative privileges to generate. There is a limit of 60 requests per minute, shared between all keys. Self-hosted users can change this in their `app.yml` file. Hosted customers will need to contact their hosting provider. `DISCOURSE_MAX_ADMIN_API_REQS_PER_MINUTE` : 60 ## [Data Explorer](https://meta.discourse.org/t/32566) Plugin API rate limits `DISCOURSE_MAX_DATA_EXPLORER_API_REQ_MODE`: default `warn` , this rate limit applies out of the box. (other options are `block` , `warn+block` , and `none` ) `DISCOURSE_MAX_DATA_EXPLORER_API_REQS_PER_10_SECONDS`: 2 Note: The requests made via the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) UI do not count towards the rate limit. ### What should I do if I hit a rate limit and get throttled? If you are consuming the API programmatically and receive back a `429` status code throttle reply you should respect it and slow down. As an end user you should not really experience rate limits if you do, slow down. You could trigger it by opening 50 tabs real quick or doing something like that. ### Firewall and proxy warning! ⚠ If you are running a reverse proxy which is mis-configured Discourse may think all the requests are coming from a single IP address, it is very likely you will hit rate limits early. Be sure to configure your reverse proxy to forward the IP correctly. ### How do I amend these limits? To amend the limits add the desired change into your `app.yml` file in the `env` section. > :discourse: If you are hosted by Discourse, and on an [Enterprise plan](https://www.discourse.org/enterprise), contact [team@discourse.org](mailto:team@discourse.org) it you need to adjust any of these limits. > > Global Rate Limits are not adjustable on [Free, Starter, Pro, or Business plans](https://www.discourse.org/pricing). > Last edited by @MarkDoerr 2026-09-01T23:18:34Z > > Last checked by @MarkDoerr 2026-09-01T23:18:42Z > > > **Check document** > > > > Perform check on document: --- _[View the full topic](https://meta.discourse.org/t/available-settings-for-global-rate-limits-and-throttling/78612)._
