Coder vs OpenMQTTGateway
A side-by-side editorial comparison of Coder and OpenMQTTGateway — release velocity, themes, recent moves, and the top alternatives to consider.
Coder vs OpenMQTTGateway: at a glance
What is Coder?
Coder ships the same security backports to three release lines in one afternoon.
Coder's feed now shows supported lines on v2.29, v2.34 and v2.37, the last confirming a v2.37 mainline this feed never captured. On November 3 all three got the same fix set: a gomarkdown advisory, anchored CSRF exemption patterns, a group-sync fix that stops adding users to another org's groups, and a row lock against double-claimed prebuilds. Late October's releases tightened API key scopes, agent credential access and skill file reads.
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.

Coder
5.0INFRA · APIS
Coder ships the same security backports to three release lines in one afternoon.
◆ Current state
Coder's feed now shows supported lines on v2.29, v2.34 and v2.37, the last confirming a v2.37 mainline this feed never captured. On November 3 all three got the same fix set: a gomarkdown advisory, anchored CSRF exemption patterns, a group-sync fix that stops adding users to another org's groups, and a row lock against double-claimed prebuilds. Late October's releases tightened API key scopes, agent credential access and skill file reads.
◆ Where it's heading
The visible work is security hardening applied in parallel across long-lived branches, with most fixes centred on permission boundaries: org scoping, key scopes, agent credentials. The Anthropic retry fix in 2.34 and 2.37 shows AI agent plumbing now ships in the server. Feature releases on the mainline remain invisible here, so the feed reads as maintenance only.
◆ Prediction
More coordinated backport rounds are likely, as each permission fix lands on all three lines; what v2.37 itself added is unclear from these entries.
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.
