# Spectrum IoT vs MQTT

The clearest difference is in-app purchases: Spectrum IoT at none against MQTT's 2. Spectrum IoT also leads on ads (none vs shown) and update cadence (every 3 months vs every 16 months). On price and device support there is nothing between them.

Both are free to download. MQTT sells 2 one-off in-app purchases. Spectrum IoT asks for nothing beyond the download.

Spectrum IoT ships an update every 3 months, MQTT every 16 months. The most recent releases landed on October 27, 2026 and October 25, 2026 respectively.
