OpenMQTTGateway vs GravityKit
A side-by-side editorial comparison of OpenMQTTGateway and GravityKit — release velocity, themes, recent moves, and the top alternatives to consider.
OpenMQTTGateway vs GravityKit: at a glance
What is OpenMQTTGateway?
OpenMQTTGateway follows its 22-month comeback with a quick reboot-loop fix.
OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.
What is GravityKit?
GravityKit folds every GravityView extension into one Pro plugin.
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.

OpenMQTTGateway follows its 22-month comeback with a quick reboot-loop fix.
◆ Current state
OpenMQTTGateway shipped v1.9.0 on November 7, its first release since January 2025. It moves to the Arduino ESP32 core 3.x, ships Theengs Decoder 2.5.0 with a fix for a BLE advertisement parsing flaw affecting every earlier release, and hardens buffer handling across MQTT, HTTP, BLE and RF input. Upgrade notes warn that some Home Assistant unique_ids change and that encrypted BLE devices are skipped until a key is set.
◆ Where it's heading
Earlier releases made the gateway independent of controllers and external brokers. The return release is about safety and a modern ESP32 base rather than new features, which suggests the project is resetting its foundation before resuming feature work.
◆ Prediction
Expect the promised security advisory for the Theengs Decoder flaw and 1.9.x fixes for the Home Assistant entity changes; whether regular cadence resumes is not yet clear from the entries.
GravityKit
5.0INFRA · APIS
GravityKit folds every GravityView extension into one Pro plugin.
◆ Current state
GravityKit ships a weekly Launch Log across its Gravity Forms add-ons, mostly security fixes and small field options. The November 12 release bundles every GravityView extension and layout into one Pro plugin with Live Filters, Connected Views and an Edit Window; the November 13 log adds paid, ranked Featured Tiers, a Pages with this View menu and more security fixes. October's notable items were Visual Merge Tags, AI-built boards and AI-managed calendars.
◆ Where it's heading
GravityKit is consolidating a sprawl of separate add-ons into fewer, larger products while steadily adding AI-assistant hooks to individual tools. Paid Featured Tiers suggest the Pro bundle is also a vehicle for listing and directory use cases.
◆ Prediction
Expect the weekly logs to continue with security fixes, and more products to follow GravityView into bundled editions.
