Our free plan stays free

• headscale

  221 19,446 9.2 Go

  An open source, self-hosted implementation of the Tailscale control server

Tailscale doesn't, but there's another opensource project which does provide control plane: https://github.com/juanfont/headscale.

Even with a on-prem control plane, you probably want logging setup to detect when unusual nodes get pushed to the accessible list of nodes on your clients.

• innernet

  60 4,832 5.8 Rust

  A private network system that uses WireGuard under the hood.

  

While not apples-to-apples and less polished, we're slowly building up https://github.com/tonarino/innernet as a fully open-source (and self-hosted) alternative to things like Tailscale. It controls vanilla WireGuard under the hood (kernel or userspace implementations), and is lower level (no graphical interfaces yet), though, but depending on your needs it might still fit :).

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• Nebula

  140 13,717 8.6 Go

  A scalable overlay networking tool with a focus on performance, simplicity and security

  

• cloudflare-connectivity-test

  2 38 0.0 Vue

  Test the current network congestion of Cloudflare based on datacenter routing

Cloudflare, which went public in 2019, has done pretty well with their free tier, with their reasoning being:

> Our free customers create scale, serve as efficient brand marketing, and help us attract developers, customers, and potential employees...

So for as long as they note that free Tailscale users are worthwhile for how they are effectively free marketing and attract clientele, it shouldn't be a problem. Tailscale doesn't proxy traffic either so the overhead of having free tier customers shouldn't be huge.

  27 1,654 8.5 Python
