The user interface is highly customizable for the end-user, and it's pretty intuitive compared to other LMSs I have used. The back end is also quite straight-forward. Other LMSs I have used (looking at you, SumTotal) are a nightmare on the backend, with multiple nested menus, incomprehensibly named data fields, non-intuitive methods for building courses and curricula, etc. That isn't the case with Docebo. Docebo is clean, modern, and pretty fast. It doesn't require you to be an expert LMS administrator to make sense of it, and it doesn't feel like a bogged-down legacy product like most other LMSs on the market.
The localization tool is hugely powerful. The fact that the interface is available in so many languages "out of the box" is huge for our international user base. My colleagues in the Russia/CIS region were delighted to see Bosnian and Kazakh as options. The translations aren't always exactly what we want them to say, but it's very easy to make custom changes to the localizations.
It's not perfect, but Docebo is always making incremental improvements. Almost everything on my wish list has eventually been ticked off as they develop the product. The implementation of the central repository was the most important thing for me, as it made it much easier to update SCORM courses without having to ensure the manifest file was identical. I have found everyone on the Docebo team pleasant to work with. Support is responsive and helpful. Review collected by and hosted on G2.com.
