Really like this product direction. Building a self-hosted licensing system with machine binding, plan enforcement, and a simple installer solves a very real problem for software vendors. I think this will especially resonate with developers who want more control, lower costs, and less dependence on external SaaS licensing platforms.
This is cool — self-hosted licensing is something a lot of indie devs need but end up rolling their own janky solution for. The $15/month VPS angle is smart, most licensing SaaS platforms charge way more than that just for the service itself. Machine binding is the feature that would sell me on this. How does it handle cases where someone upgrades their hardware — does the license just break or is there a migration flow?
