Software that grows with the models.

21stware builds softwares for the agent era. The product suite — vav, XBuckle, originai, handymd, agent-the-zsh, and Tossy — ships from github.com/21stware, under one brand and one subscription — Free through Enterprise.

Most products are agent-native: local workstations, runtimes, specs, and shells that agents actually use — not a chat bolt-on on a CRUD app.

The catalog is designed to grow. New products join your tier as they launch. Existing products keep iterating. You are not buying a frozen SKU list — you are subscribing to a living suite.

We are 21stware on GitHub.
