App capabilities, now for all your apps

Tailscale’s identity-based access controls allow for building powerful, secure applications on entirely private tailnets. You can already leverage user identity with our Go-based tsnet. Now we’re building on our prior work and taking it a significant step further, with Tailscale app capabilities. With the latest version of Tailscale’s serve function, third-party applications can accept grants through standard HTTP headers, in whatever language suits your needs.
