Praex

Praex is an innovative AI coding agent designed to streamline and enhance the software development process. It leverages a family of proprietary models—Velox II for speed, Faber II for deep reasoning, and Lucia II (coming soon) for frontier capabilities—post-trained on top open models. Praex can read your code repositories, suggest and implement edits with your approval, run tests, and provide clear explanations for every change, making it an invaluable assistant for developers. Its versatile deployment options include terminal, desktop app, and browser, with session continuity across devices via /rc commands. The open-source terminal agent (MIT license) allows for customization and transparency, while the Pro plan offers additional features at $20/month, making it accessible for both hobbyists and professionals.
