Non-Commercial / Donation-Funded enterprise

Signal provides its messaging service free of charge to end users; there is no commercial API SKU, no developer plan, and no per-call pricing. Use of the Signal Protocol via open source libraries is governed by upstream license terms rather than a Signal Foundation contract.
