Why our best software is the one you cannot sign up for
A harness that holds your credentials and can act on your systems is a security surface, not an app.
SynthOS is the piece of software we are most confident about and the only one without a signup button. That looks like artificial scarcity, so it is worth setting out the actual reasoning.
The thing is a harness. It holds keys, connects to internal systems, and takes actions. That combination is not an application, it is a security surface, and the open agent frameworks have already demonstrated at scale what happens when you hand one to anybody with an email address. Deployments get exposed. Third party extensions get installed without review. The failure is not a bug in the software, it is the deployment model.
There is also nothing honest to give away. The value is in the configuration: which of your tools it can touch, which actions need approval, where the data boundary sits. A self-serve version would ship the empty shell, and the empty shell is the part anyone can build.
And the pricing does not support a free tier. It runs on your own keys, so we take no margin on inference. There is no per-token economics quietly funding free users, which is a deliberate structural choice and also the reason a funded competitor cannot undercut it.
So it is closed, and access comes with a configuration and a conversation. If that reads as precious, the alternative was to make it easy to deploy badly, and we would rather explain this than clean that up.
