Leon features
- Multi-agent support. Run Claude Code, Codex, OpenCode or any other coding agent side-by-side in real terminals.
- Project-wide tree view. Organise machines, projects, git worktrees and agent sessions in a single searchable tree.
- Remote pairing with code. Connect another computer via a one-time pairing code; communication is end-to-end encrypted.
- GPU-rendered terminals. iTerm-style split terminals with fast GPU rendering run inside real login shells.
- Agent memory. Persist and search shared memory entries per project, visible to all agents.
- Task board integration. Create, sync and manage tasks; agents can read/write the board and sync with GitHub issues.
Selvedge features
- Local SQLite storage. Decisions are saved in a project-local .selvedge/selvedge.db file without external services.
- Agent-agnostic integration. Connects to Claude Code, Codex, Copilot, Cursor, Gemini CLI and Windsurf through MCP. Setup and lifecycle-hook support vary by client.
- Explicit decision recording. Save what was decided, which approaches were rejected, why, and the conditions for reconsidering them.
- CLI and MCP access. Retrieve stored decisions through a Python CLI or MCP calls in new sessions.
- Zero-account, open source. MIT-licensed, no subscription, and makes no LLM calls itself.
- Project-portable database. Carry the SQLite file to another machine or export a readable decision log.
