OpenMQTTGateway vs OctoPrint: at a glance
What is OpenMQTTGateway?
OpenMQTTGateway spent three years shedding its dependencies, then stopped shipping entirely.
The last release was January 2025, a single bug fix for adaptive scanning restarting the gateway. Before that, the project moved steadily toward standing alone: 1.8.0 embedded an MQTT broker via PicoMQTT so a gateway no longer needs an external server, 1.6.0 added a web interface so it no longer needs a home automation controller to configure, and 1.5.0 brought device trackers for presence detection with over-the-air updates from the controller. Hardware arrived alongside software, with the Theengs Bridge in 1.7.0 and the Theengs Plug in 1.3.0.
What is OctoPrint?
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.

OpenMQTTGateway
0.0INFRA · APIS
OpenMQTTGateway spent three years shedding its dependencies, then stopped shipping entirely.
◆ Current state
The last release was January 2025, a single bug fix for adaptive scanning restarting the gateway. Before that, the project moved steadily toward standing alone: 1.8.0 embedded an MQTT broker via PicoMQTT so a gateway no longer needs an external server, 1.6.0 added a web interface so it no longer needs a home automation controller to configure, and 1.5.0 brought device trackers for presence detection with over-the-air updates from the controller. Hardware arrived alongside software, with the Theengs Bridge in 1.7.0 and the Theengs Plug in 1.3.0.
◆ Where it's heading
The arc through 1.2 to 1.8 is one of progressive independence — first from a controller for configuration, then from a broker for messaging — turning a bridge component into a self-contained device. Release intervals widened throughout: monthly in early 2023, then annual, then nothing for nineteen months. Whatever the roadmap was, the feed has not recorded activity since.
◆ Prediction
The evidence here does not support a confident prediction about what ships next; the project has published nothing in nineteen months. If it resumes, the unfinished thread is the embedded broker, which shipped in 1.8.0 and received only a scanning bug fix afterward.
OctoPrint
2.5INFRA · APIS
OctoPrint 2.0 turns serial into one connector among several, and breaks plugins doing it.
◆ Current state
The entire feed is the 2.0.0 release candidate series — four RCs between April and July 2026, no stable tag. The testing asks reveal what changed underneath: blocklisted serial ports and baud rates are migrated into a serial connector, testers are asked which connector they used when a printer lands in an error state, and rc1 raises Klipper and Moonraker printers directly. Each RC restates the same release-candidate warnings, so the notes read as testing instructions rather than a changelog.
◆ Where it's heading
Serial is being demoted from the way OctoPrint talks to a printer to one implementation of a connector interface, which is the structural precondition for supporting printers that speak something else. The cost is deliberate: rc1 removes deprecated APIs, warns that plugins will break, and points users at a recovery page to restart in safe mode. A maintainer running a long public RC cycle on a single-maintainer project is managing that breakage rather than rushing past it.
◆ Prediction
Expect further RCs until the connector migration stops producing reports, with the plugin ecosystem's readiness — not the core code — deciding when 2.0.0 goes stable.
