Praex is an AI coding agent that runs on its own model family: Velox II (free, fast), Faber II (Pro, deep reasoning) and Lucia II (frontier, coming soon), post-trained from the best open models. It reads your repo, edits with your approval, runs your tests and explains every change. Use it in the terminal, the desktop app or the browser, and continue any session from your phone with /rc. The terminal agent is open source (MIT). Free to start, Pro $20/month.
