What do you like best about ATLAS CMMS / GMAO?

Been using Atlas CMMS for 8 months now. Love that it's fully open source on GitHub - no vendor lock-in BS. The Android app is clutch for our field techs, they can update work orders on the go without any hassles.

Pros:

Completely free (we're self-hosting with Docker)

Super easy to set up if you know basic IT stuff

Mobile app actually works well

Clean interface - didn't need much training for the team Review collected by and hosted on G2.com.

What do you dislike about ATLAS CMMS / GMAO?

You need someone technical to maintain it

No hand-holding support like paid solutions

no iOs App yet Review collected by and hosted on G2.com.

What do you dislike about ATLAS CMMS / GMAO?

There are some minor bugs, but this is due to the relatively recent release. However, the developers are working hard to make the necessary fixes. Review collected by and hosted on G2.com.

Software for complex engineering, testing, and operational procedures. At Epsilon3, we modernize space missions and complex engineering and testing by building the industry standard of operational software. We are a team of engineering and design leaders from Northrop, Google, and SpaceX, where we ran operations first-hand to bring American astronauts to the ISS. Current mission tools are neglected in a program lifecycle, creating inefficiency, errors, and added costs over the course of a project. Epsilon3 arms operators with the best possible tools throughout an entire project’s lifecycle, which result in 10X more efficiency and operator-friendliness.
