Thinktecture Open Source

Thinktecture loves open-source and actively contribute back to the community. Check out some of our projects:


Thinktecture RelayServer enables a bidirectional, secure communication between clients, mobil devices and applications with an on-premises application behind routers and firewalls via https with complete control and auditing of allowed participants and permitted data.


IdentityServer is a framework and a hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

Because of the popularity of this project it is now under full time management by the two independent associates of Thinktecture Dominick Baier and Brock Allen.
