"ION: The Swiss Army Knife of Manufacturing Software"

5/5

What do you like best about First Resonance ION Factory OS?

ION is an intuitive manufacturing tool with features that go far beyond those of a standard MES system. It truly feels like a Swiss army knife for manufacturing needs. The software is ready to use straight out of the box and is straightforward to implement and configure. We were able to tailor the tool to our business requirements in under two months. Additionally, customer support was always accessible and played a key role in enabling the configuration process. ION's open API is easy to work with, allowing users to build apps and dashboards on top of the ION platform to fill any gaps that are present. Review collected by and hosted on G2.com.

What do you dislike about First Resonance ION Factory OS?

ION is still in development. In the past, they have struggled to deliver updates and changes promptly, largely because of the technical debt that has accumulated in ION's codebase over the years. This has often forced customers to implement temporary fixes to manage these issues. Recently, First Resonance has updated their code to be more modular, which should make future updates and changes more time efficient. Review collected by and hosted on G2.com.
