It features multi-session support for parallel agents on the same project, LSP-native context, privacy-first architecture (no code/context stored), and a $10/month plan bundling GLM-5, Kimi K2.5, and MiniMax M2.5. The HN post hit 802 points and 359 comments — largest AI story on HN today — signaling this is emerging as the primary open-source challenger to Claude Code and Copilot Workspace.
