POEditor believes in the Open Source movement and supports it, offering free localization tools for all Open Source projects. You can translate Open Source projects without using up strings from your account’s limit.
Free Open Source Localization Management
You can use POEditor as a free localization platform if the software you want to translate has an OSI-approved license. All you have to do is create a localization project on POEditor and send a request to localize your software for free. You can find out how to make the request here.
When you fill out a request for an Open Source Project, you have to prove that your project is Open Source by providing the type of OSI approved license, a project description and a link to your project page.
What are Open Source projects?
Open Source software is software that can be freely used, changed, and shared (in modified or unmodified form) by anyone. Open Source software is developed and distributed under licenses that comply with the Open Source Definition. The Open Source Initiative (OSI) is a global non-profit that supports and promotes the Open Source movement. Among other things, OSI maintains the Open Source Definition, and a list of licenses that comply with that definition.
