How to sponsor
Two channels, depending on whether you need a VAT-enabled invoice.
GitHub Sponsors
Personal or company accounts, monthly or one-off. Fastest path; works for individuals and most companies.
Sponsor on GitHub →Open Collective
For company sponsorships that need a VAT-enabled invoice, EU-compliant. Use this when your accounting needs a proper invoice.
