I run multiple Claude Code sessions daily across different projects and it would get pretty messy - no visibility into costs, agents stepping on each other's files, context lost between sessions. So I built Myrlin, baking in a bunch of QoL features I wish I had. It’s a Browser-based workspace manager that sits on top of Claude Code:
- 4-pane embedded terminals (xterm. js + node-pty) for side-by-side sessions
- Real-time cost tracking - parses Claude's JSONL session logs per model
- Conflict detection - warns when multiple agents edit the same files
- Session templates, workspace docs, 13 themes
- Auto-discovers every Claude session you've ever run
Everything local. No cloud, no accounts, no telemetry.
One command:
“npx myrlin-workbook”

Would love feedback on the UI or features you'd wan to see. Happy to
answer architecture questions.
Thanks!
