I posted a comparison a short while ago: https://lemmy.world/post/1452988
I recently decided on headscale as a coordination server with tailscale apps/clients for my setup. My rationale was:
- Tailscale seems to be dominating adoption. This isn't a technical consideration but it often correlates with project velocity going forward.
- Headscale the self-hosted server is unofficially but decently supported by tailscale the company. They employ the dev and don't seem to be trying to kill the project or mess with it much. It includes most features useful to selfhosted installs, but reserves multi-network setups as the domain of the official tailscale coordination server which strikes me as a pretty reasonable way to segment the market.
- Tailscale has great client coverage for Linux, windows, Mac, android, and iOS.
- I didn't do a point by point feature comparison, but my sense was that tailscale/headscale meet or beat the featuresets of other projects, so I didn't see any technical reasons to buck against community momentum.
