Tinode is an open-source instant messaging platform. Its server is written in Go and can run in a cluster, and its client software is licensed under Apache 2.0. Developers can extend it with authentication schemes, database back ends, bots and plugins. It can be self-hosted, or used through the hosted option Tinode Cloud Hosting. For organisations that now use hosted chat APIs such as Sendbird, it is an alternative that can run on their own infrastructure.
Tinode LLC has its address in Reno, Nevada, in the United States, and is therefore subject to US law. Its privacy policy states that personal information may be stored in the European Union, the United States or other countries, on its own servers or those of service providers, and that authorities may access it on a lawful request. The policy contains no GDPR section and no processing agreement. For a European organisation, the practical option is self-hosting on European infrastructure, which keeps the data under the organisation's own control.
