Package Exports
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@cryptiklemur/lattice) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Lattice
Multi-machine agentic dashboard for Claude Code.
Monitor sessions, manage projects, track costs, and orchestrate across mesh-networked nodes.
Alpha — Lattice is under active development. APIs and features may change.
Quick Start
npm install -g @cryptiklemur/lattice
latticeOpens at http://localhost:7654. Add projects through the UI or point it at a directory with a CLAUDE.md file.
Install with Bun
bun install -g @cryptiklemur/lattice
latticeDevelopment setup
git clone https://github.com/cryptiklemur/lattice.git
cd lattice
bun install
bun run devHot-reloads both server and client automatically.
Features
Chat & Sessions
Send messages, approve tool use, and monitor context window usage with per-message token counts. Browse, rename, delete, and search sessions with date range filtering and hover previews. Sessions automatically get descriptive titles from the first exchange.

Analytics & Cost Tracking
Track spending, token usage, cache efficiency, and session patterns with 15+ chart types. Set daily cost budgets with configurable enforcement (warning, confirm, or hard block).

Workspace
Open multiple sessions as tabs and switch between them. Split-pane via right-click context menu. Pin important messages with bookmarks — jump between them per-session or browse the global bookmarks view. Per-project tab state persists across navigation.
Press ? for keyboard shortcuts, Ctrl+K for the command palette.

Themes & Settings
23 base16 themes (12 dark, 11 light) with OKLCH color space. Configure MCP servers, environment variables, rules, permissions, and Claude settings through the UI.

Infrastructure
- Mesh networking — Connect multiple machines with automatic discovery and session proxying
- MCP servers — Add, edit, and remove at global or project level
- Skill marketplace — Search and install from skills.sh
- Memory management — View and edit Claude's project memories
Mobile
Responsive design with touch targets, swipe-to-open sidebar, and optimized layouts.
Architecture
Bun monorepo with three packages:
| Package | Stack |
|---|---|
shared/ |
TypeScript types, message protocol, constants |
server/ |
Bun WebSocket server, analytics engine, mesh networking |
client/ |
React 19, Vite, Tailwind, daisyUI, 23 themes |
Communication via typed WebSocket messages. Sessions managed through the Claude Agent SDK. Client state via Tanstack Store + Router.
Security
| Feature | Detail |
|---|---|
| Authentication | Passphrase with scrypt hashing, 24-hour token expiration |
| Rate limiting | 100 messages per 10-second window per client |
| Attachments | 10MB upload limit |
| Bash commands | cd boundary-checked against project directory |
| Mesh pairing | Tokens expire after 5 minutes |
| Shutdown | Graceful drain of active streams |
Testing
bun run dev # start server
bunx playwright test # run testsPlaywright suite covers onboarding, session flow, keyboard shortcuts, accessibility, message actions, and session previews.
