Is SkinsRestorer Free and Open Source?

Yes. SkinsRestorer describes itself as "open source, and free forever" on its official site, and its source code is hosted on GitHub where anyone can view or contribute to it. The site also has a Pricing page you can check yourself if you want to confirm there are no paid tiers. If you're evaluating it for a server, the practical takeaway is: you can install and use it without paying, and you can inspect or modify the code.

What "free" and "open source" mean here

• Free: The site states the plugin is free forever. There is a Pricing page linked in the site navigation, so you can verify the current situation directly rather than relying on a secondhand claim.
• Open source: The project is hosted on GitHub, and the site explicitly invites contributions there ("you can contribute to it on GitHub"). That means the code is publicly available to read, fork, and submit changes to.

One caveat worth stating plainly: "free" and "open source" are separate things. A project can be one without the other. Here the site claims both, and the GitHub link is the evidence for the open-source half.

How to verify it yourself

1. Open the official site and look for the Pricing link in the navigation. Check whether any paid plan or license is listed.
2. Follow the GitHub link from the site to reach the repository. From there you can browse the code, open issues, and read contribution guidelines.
3. If you want to contribute, the GitHub repo is the place to start — that's the channel the project points to for code contributions.

Expected result: you'll be able to confirm the licensing and pricing status from the primary sources rather than from a summary.

Ways to get involved or get support

The site lists several community and support channels alongside GitHub:

Ko-fi is a voluntary support link, not a requirement to use the plugin — the site frames the plugin itself as free, with Ko-fi as an optional way to back the project.

Common questions people ask alongside this

• Do I need to pay to use it on my server? Based on the site's own wording, no — it's described as free forever. Check the Pricing page for the current state.
• Can I modify it? The GitHub repository is public and contributions are invited, which is the signal that the code is open for inspection and changes.
• Is support paid? The site points to Discord and GitHub for community help; nothing in the provided material indicates a paid support tier.

If your real question is whether it fits your server setup, the free/open-source answer is only half of it — you'll also want to confirm platform support and offline-mode behavior, which the site addresses separately.
