Fund the project, not the company.
Stratos is free and will never have a paid tier. The project is funded entirely by donations from people who use it. If Stratos has saved you time, consider sending a tip — every cent goes to hosting, code-signing certificates, and the next release.

Frequently asked
Is Stratos free to use?+
Yes — every feature in every release is free. There is no paid tier and there will never be one.
Is my donation tax-deductible?+
No. Stratos is not a registered non-profit; donations are gifts to an individual maintainer. Payoneer and Wise may issue a receipt for your records, but no tax receipt is provided.
Can my company sponsor?+
Yes. For invoices or sponsorship packages over $500, email sponsors@stratos.app.
What if I need a refund?+
Donations are non-refundable. If you sent a tip by mistake, reply to the Wise or Payoneer email receipt and the maintainer will return it.
Is there a way to donate without a fee?+
Crypto is not supported at the moment. Wise and Payoneer are the only paths; both charge a small transfer fee but accept cards and local bank transfers in 100+ countries.
