Managed MQTT Broker · Singapore Region
Every customer gets their own Mosquitto process instead of a slot on a shared broker with a locked-down topic prefix. Any topic tree, TLS, REST publish and webhook rules. From Rp 75,000 a month in Indonesia, or $49 a month by card everywhere else.
Set the device count, publish interval and payload size to see whether you fit the Starter plan.
Assumes 1 subscriber per topic on average, about 30 B overhead per message, 30 days per month. Webhook deliveries are counted separately.
Shared brokers restrict your topics to username/# and run every customer in one process. Here you get a process of your own.
An isolated Mosquitto per customer: no noisy neighbors, no username/# topic restriction.
Your server sends a POST, no persistent MQTT connection needed. Works from serverless apps.
Rules like "if value > X, send a POST", with HMAC signatures, automatic retries and unit-conversion presets.
Every connection is encrypted, using a wildcard certificate that renews automatically.
Servers in Singapore, close to devices in Indonesia and the rest of Southeast Asia.
In Indonesia, top up a monthly balance with QRIS, no credit card needed. Elsewhere, the Global plan bills a card in USD. Console and uptime monitoring included.
Part of: Monitor & connect · See the plant: dashboards and alarms, machine OEE, remote access, messaging.
