The Complete AI Development System
Two products that work together: Lattice Project Builder for new project blueprints, and Lattice Core for guardrails inside existing repos.
Lattice Project Builder
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 Project Builder Works
PROJECT_GUIDE.md
Complete architecture document with milestones, requirements, and technical decisions.
CI/CD Workflow Automation
GitHub Actions workflow that runs verify on every push. Quality gates from day one.
Custom Bootstrap Command
A single npx command that sets up your entire project with all configurations.
Basic Planning Mode
Fast single-pass generation. Great for straightforward projects.
Pro Planning Mode
Multi-model AI deliberation. Deeper analysis for complex projects.
Includes Lattice Core
Every Project Builder project includes full Lattice Core setup with guardrails and verification.
Lattice Core
Free ForeverAdd AI guardrails to any existing project. One command generates AGENTS.md, editor-specific rules, verification commands, and repo safety workflows that keep your AI assistant up to date.
Run in any project directory. Lattice Core auto-detects your stack.
One Setup Command
Run `npx latticeai` to detect your stack and apply AGENTS.md, Cursor rules, Claude settings, Copilot instructions, and Codex guidance.
AI Editor Support
Generates .cursor rules, AGENTS.md, docs/rules/codex.md, CLAUDE.md, .claude/settings.json, and GitHub Copilot instruction files so Cursor, Claude Code, GitHub Copilot, and Codex run with aligned guardrails.
Version-Aware Rules
Injects your exact stack versions into AI context. Prevents AI from using outdated APIs.
Verify Command
Run `npx latticeai verify` or `npm run verify` for the standard quality loop. 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`, `npx latticeai drift`, or `npx latticeai doctor --agents` to review project health, compliance score, and generated 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.

Frequently Asked Questions
What's the difference between Lattice Core and Lattice Project Builder?
Core is free and hardens existing projects with AGENTS.md, editor-specific rules, verification, drift detection, and security workflows. Project Builder is paid and generates complete project plans for new projects. Project Builder includes Core automatically, so you get both when you use Project Builder.
Do I need both Core and Project Builder?
No. If you have an existing project, use Core (free). If you're starting a new project, use Project Builder (paid, includes Core). You can't use Project Builder 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. Project Builder 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, Next.js Landing, Next.js + tRPC, and Expo + Supabase. Use them with `npx latticeai setup --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 Project Builder (project planning).
What AI editors does Lattice support?
Core supports Cursor, Claude Code, GitHub Copilot, and Codex by generating both human-readable and structured guardrails (.cursor/rules.md, .cursor/rules/lattice-core.mdc, AGENTS.md, docs/rules/codex.md, CLAUDE.md, .claude/settings.json, .github/copilot-instructions.md, and .github/instructions/lattice-core.instructions.md).
