| `twilio-verify-service` | `NTFY_TWILIO_VERIFY_SERVICE` | *string* | - | Twilio Verify service SID, e.g. VA12345beefbeef67890beefbeef122586 |
| `keepalive-interval` | `NTFY_KEEPALIVE_INTERVAL` | *duration* | 45s | Interval in which keepalive messages are sent to the client. This is to prevent intermediaries closing the connection for inactivity. Note that the Android app has a hardcoded timeout at 77s, so it should be less than that. |
| `manager-interval` | `NTFY_MANAGER_INTERVAL` | *duration* | 1m | Interval in which the manager prunes old messages, deletes topics and prints the stats. |
| `message-poll-limit` | `NTFY_MESSAGE_POLL_LIMIT` | *number* | *(uncapped)* | Max number of cached messages returned per topic when the cache is replayed (a poll, or a `since` request). A poll without a `since` cursor returns a topic's entire cache, which is unbounded in size. When set, the newest messages are kept and the response carries an `X-Messages-Truncated: 1` header. Together with `message-size-limit` this bounds the memory one replay can allocate. |
| `message-size-limit` | `NTFY_MESSAGE_SIZE_LIMIT` | *size* | 4K | The size limit for the message body. Please note that this is largely untested, and that FCM/APNS have limits around 4KB. If you increase this size limit, FCM and APNS will NOT work for large messages. |
| `message-delay-limit` | `NTFY_MESSAGE_DELAY_LIMIT` | *duration* | 3d | Amount of time a message can be [scheduled](publish.md#scheduled-delivery) into the future when using the `Delay` header |
| `global-topic-limit` | `NTFY_GLOBAL_TOPIC_LIMIT` | *number* | 15,000 | Rate limiting: Total number of topics before the server rejects new topics. |
| `upstream-base-url` | `NTFY_UPSTREAM_BASE_URL` | *URL* | `https://ntfy.sh` | Forward poll request to an upstream server, this is needed for iOS push notifications for self-hosted servers |
| `upstream-access-token` | `NTFY_UPSTREAM_ACCESS_TOKEN` | *string* | `tk_zyYLYj...` | Access token to use for the upstream server; needed only if upstream rate limits are exceeded or upstream server requires auth |
| `visitor-attachment-total-size-limit` | `NTFY_VISITOR_ATTACHMENT_TOTAL_SIZE_LIMIT` | *size* | 100M | Rate limiting: Total storage limit used for attachments per visitor, for all attachments combined. Storage is freed after attachments expire. See `attachment-expiry-duration`. |
| `visitor-attachment-daily-bandwidth-limit` | `NTFY_VISITOR_ATTACHMENT_DAILY_BANDWIDTH_LIMIT` | *size* | 500M | Rate limiting: Total daily traffic limit per visitor, covering attachment downloads/uploads and messages replayed from the cache by poll requests. This is to protect your bandwidth costs from exploding. |
| `visitor-attachment-daily-bandwidth-limit` | `NTFY_VISITOR_ATTACHMENT_DAILY_BANDWIDTH_LIMIT` | *size* | 500M | Rate limiting: Total daily traffic limit per visitor, covering attachment downloads/uploads and messages replayed from the cache by poll requests. This is to protect your bandwidth costs from exploding. |
| `visitor-email-limit-burst` | `NTFY_VISITOR_EMAIL_LIMIT_BURST` | *number* | 16 | Rate limiting:Initial limit of e-mails per visitor |
| `visitor-email-limit-replenish` | `NTFY_VISITOR_EMAIL_LIMIT_REPLENISH` | *duration* | 1h | Rate limiting: Strongly related to `visitor-email-limit-burst`: The rate at which the bucket is refilled |
| `visitor-message-daily-limit` | `NTFY_VISITOR_MESSAGE_DAILY_LIMIT` | *number* | - | Rate limiting: Allowed number of messages per day per visitor, reset every day at midnight (UTC). By default, this value is unset. |
