Cline and Roo Code brought autonomous agents into VS Code. Liminal targets the same jobs — multi-file edits, terminal, research — without tying you to one editor or one vendor’s UX.

What Cline and Roo Code do well
Both extensions excel when you want the agent in the sidebar while you edit:
- Fast file picks from the open workspace
- Tight loop between chat and diffs
- Familiar VS Code keybindings and themes
Roo Code adds mode switching (architect vs code), which helps structure longer tasks inside the extension.
Where a standalone harness helps
Liminal runs as its own terminal UI and web UI, so the agent survives when you:
- Switch between JetBrains, VS Code, and a remote SSH box
- Run parallel sub-agents or declarative workflow phases across a repo
- Need Obsidian vault memory, browser automation, or document-engine tools
- Want JSONL session traces for compliance without exporting from an extension log
