FAQ

EMQX FAQ

Still curious? Email info@appsgit.com.

Is EMQX free and open source?

Not by the OSI definition. EMQX is source-available rather than open source: its code is public under the BSL 1.1, which is not an OSI-approved open-source license. The Business Source License lets you read, modify and self-host the code, but production use is limited to what its Additional Use Grant allows, and each release converts to an open-source license after a set date. Check the license in the repository before using it commercially.

Can I run EMQX with Docker?

Yes. EMQX provides a Docker image, so you can run it on any Linux server with Docker and Docker Compose installed. The project README lists the image name and the environment variables to set.

What are the best alternatives to EMQX?

Popular self-hosted alternatives to EMQX include Home Assistant, Tasmota and Node RED.

The most recent commit to EMQX was on Oct 26, 2026 with 7,774 commits in the past twelve months. The latest release is 6.3.2, published Oct 16, 2026. It had 167 open issues on GitHub. appsgit's project-health label for it is "Active" as of Oct 26, 2026.
