What This Repository Does

This is a public directory of companies that actively support open source software through donations or employee time. It's a way to recognize and celebrate organizations that give back to the projects they rely on. If you're curious which companies are funding the code behind the tools you use every day, this list gives you those answers.

How It Works

The repository is simply a curated list organized by country, with each company linked to proof of their support. To make the list, a company needs to meet two basic criteria: it must be a profit-making business that systematically supports open source projects made by others (not just their own), and there needs to be public documentation showing where that support goes—usually a blog post, donation page, or corporate statement. Anyone can contribute by submitting a pull request to add new companies or update existing entries.

Who This Is For and Why It Matters

This list serves several audiences. Founders and maintainers of open source projects can use it to identify potential corporate sponsors. Companies looking to improve their image and corporate responsibility can see how peers are contributing. Developers might use it to make informed choices about which companies to work for based on their open source values. At a deeper level, the repository addresses a real problem: open source maintainers often work for free or with minimal funding, even though companies save enormous amounts of money by using their code. By making corporate support visible, the repository encourages more companies to recognize that debt and step up their contributions.

The list includes everyone from tech giants like Google and Microsoft to smaller specialized firms, spanning dozens of countries. Each entry links to concrete evidence of support, so you can verify the claims rather than just taking the list at face value.
