The Complete AI Development System
Two products that work together: Lattice Core for guardrails, Lattice Architect for project planning.
Lattice Core
Free ForeverAdd AI guardrails to any existing project. One command generates version-aware rules, verification scripts, and keeps your AI assistant up to date.
Run in any project directory. Lattice Core auto-detects your stack.
One-Command Setup
Run `npx latticeai` to detect your stack and generate version-aware rules for Cursor and Claude Code.
AI Editor Support
Generates .cursor/rules.md for Cursor and CLAUDE.md for Claude Code. Both stay in sync.
Version-Aware Rules
Injects your exact stack versions into AI context. Prevents AI from using outdated APIs.
Verify Command
Run `npm run verify` for fast lint + typecheck. Add `--full` for complete validation.
Watch Mode
Run `npm run verify -- --watch` to continuously check your code as you make changes.
Status & Drift Detection
Run `npx latticeai status` to view project health, compliance score, and file drift.
Cross-Platform
Works on Windows, macOS, and Linux. Tested across all platforms in CI.
Auto-Update Rules
Run `npx latticeai update` to refresh rules while preserving your customizations.
Prompt Templates
Get 6 AI playbooks: feature, bugfix, refactor, test, polish, and security.
Lattice Architect
Paid PlansStart new projects in minutes, not hours. Describe what you're building, get a complete plan with PROJECT_GUIDE.md, tech stack, CI/CD workflows, and a custom setup command.
How Lattice Architect Works

Frequently Asked Questions
What's the difference between Lattice Core and Lattice Architect?
Core is free and adds AI guardrails to existing projects. Architect is paid and generates complete project plans for new projects. Architect includes Core automatically, so you get both when you use Architect.
Do I need both Core and Architect?
No. If you have an existing project, use Core (free). If you're starting a new project, use Architect (paid, includes Core). You can't use Architect on existing projects—it generates everything from scratch.
What tech stacks does Lattice support?
Core works with any JavaScript/TypeScript project: Next.js, React, Vue, Node.js, Expo, React Native, and more. Architect can generate projects for web (Next.js), mobile (Expo), and API projects.
How do the production-ready bundles work?
Bundles are pre-configured, version-pinned stacks (like Next.js SaaS, Expo Mobile). Use them with `npx latticeai --bundle <id>`. They're tested and production-ready out of the box.
Can I use Lattice Core without an account?
Yes! Core works entirely locally with no account required. Just run `npx latticeai` in your project. You only need an account for Architect (project planning).
What AI editors does Lattice support?
Core generates rules for Cursor (.cursor/rules.md) and Claude Code (CLAUDE.md). Both files stay in sync and are updated together when you run `npx latticeai update`.
