Excellent

Crowdin is the most feature-rich of the localization platforms out there. Just as important, it has the best online translation editor for translators. The problem with most localization platforms these days isn't which formats they support or any other engineering feature -- it's that the online translation part is so slow that your translators don't want to use it. Crowdin is the ONLY platform our translators actually enjoy using. That makes it a win-win. Also the customer support is excellent.

This is nitpicky but we run a lot of projects and would like to archive "old" source files without deleting them. Also the way it manages duplicates is not ideal, but we haven't found a platform that does a better job so it's hard to complain.

Crowdin helps us gather translations from our community quickly and easily. All translators immediately know how it works, because the Editor speaks for itself. This means we always have quality translations available for each app update. We're currently making the switch to Crowdin Enterprise, as its extended set of features suit us better. Crowdin offers (free) plans for open-source projects, so we don't have to worry about finances. We're having a hard time understanding why Enterprise is separate from normal Crowdin, but they both work great nevertheless.

Crowdin's core features are incredibly easy to use. With a big variety of settings and options, every project and profile is very customisable and dynamic. Last but certainly not least, Crowdin has an awesome support team. They're continuously helping users get the most out of the product and always looking for solutions on a per-case basis.

Some settings menus are a bit confusing. You'd expect some options to be found somewhere else. Additionally, the developers tend to be a bit slow adding features requested by the community. Some feature requests have been opened for a long time. The support agents do make up for this, though, and they always manage to find alternative solutions.

I like the option to add several languages to the same project and change within the same document.

Some of the languages I work with are not accepted. Moreover, the machine translation does not seem clear to know which was the last option and the best one.

I'm translator of an open-source project and I also propose, implement and use this tool in multiple companies I work for.

All my translators can work with this tool without asking many questions. Support for many formats.

Sometimes slower UI for larger projects.

I used Crowdin a lot for more than 10 years. Is our Rosetta Stone of productivity; very helpful!

Easy to use. Free for Open Source projects.

Some features such as filtering could improve.
