Lattice

4-6 hours~5 minutes

From Idea to Ready-to-Code
in Minutes, Not Hours

Lattice gives Cursor, Claude Code, GitHub Copilot, and Codex a shared blueprint before the code starts. Describe what you are building and get your plan, stack decisions, PROJECT_GUIDE.md, CI/CD, and AI guardrails in about 5 minutes. Lattice Core is free forever, and Lattice Project Builder is paid.

This sample is a real Project Builder-style guide for a scheduling SaaS. It shows the architecture decisions, milestones, guardrails, and verification contract that keep coding agents on the same plan.

# Product Goal
Launch a multi-tenant scheduling SaaS for service teams.

## Locked Stack
- Next.js 16 App Router + TypeScript strict
- Supabase Auth + PostgreSQL with RLS
- Stripe subscriptions with webhook reconciliation
- Jest + React Testing Library

## Non-Negotiable Guardrails
1. Never expose service-role credentials to the browser.
2. Verify Stripe webhook signatures before processing events.
3. Run lint, typecheck, tests, and production build before release.

## Milestone 1: Trusted Foundation
- Create auth boundaries and tenant-aware database policies
- Add subscription state reconciliation
- Ship a tested booking workflow

Have an Existing Project?

Use Lattice Core to add AI guardrails to what you already have. One command generates modern agent instructions, verification commands, and repo safety workflows that keep Cursor, Claude Code, GitHub Copilot, and Codex aligned with your real stack.

  • One setup command
  • AGENTS.md + skills + editor rules
  • Verify, watch, drift, security
  • Works with Cursor, Claude Code, GitHub Copilot, and Codex

How It Works

Three steps. Five minutes. Ready to code.

1

Describe in Project Builder

Fill out one form in Lattice Project Builder: what you're building, project type, key decisions (auth, database, UI style).

~ 2-3 minutes
2

AI Builds the Plan + Guardrails

Lattice AI creates your PROJECT_GUIDE.md, stack plan, AI rules, CI workflows, and guardrails. Supported combinations also get scaffolded setup files.

~ 15-90 seconds
3

Run One Command

Copy your custom command and run it in terminal. Lattice applies the guide, rules, config, and any scaffolded files included for your stack.

Without Lattice, you...

  • Guess at tech stack compatibility
  • Manually configure linting, TypeScript, CI
  • Write custom rules for your AI assistant
  • Hope you got the architecture right

With Lattice, you...

  • Fill out one form (what you're building)
  • Get your complete project plan
  • Paste one command
  • Start coding with AI that knows exactly what to build

Early Builder Feedback

"I used to spend my entire first day just setting up the project. Now I describe what I'm building in Project Builder, run a command, and I'm coding in under 10 minutes. The AI rules Lattice Core generates are exactly what I would have written myself - except I didn't have to."

"The Pro Planning mode is insane. I described a mobile app idea, and Project Builder came back with a full architecture, milestone breakdown, and even caught edge cases I hadn't thought of. Worth every penny for the time it saves."

Frequently Asked Questions

What is Lattice?

Lattice has two products: Lattice Project Builder for new projects and Lattice Core for existing repos. Project Builder creates a shared blueprint, AI guardrails, CI/CD, and setup packages for supported stacks. Core adds version-aware guardrails and verification to repos you already have.

How long does Lattice take to scaffold a project?

Lattice takes about 5 minutes total: 2-3 minutes to fill out the project form, 15-90 seconds for AI generation, and 30 seconds to paste and run the setup command. Manual project setup typically takes 4-6 hours.

Is Lattice Core really free?

Yes. Lattice Core is free forever. It's a CLI tool you install via npx that adds version-aware guardrails, AGENTS.md, Cursor rules, Claude rules and skills, portable Agent Skills, MCP templates, verification commands, and repo safety workflows to any existing project. Lattice Project Builder, which generates full project plans from scratch, requires a paid subscription.

What AI coding assistants does Lattice support?

Lattice generates custom rules and guardrails for Cursor, Claude Code, GitHub Copilot, and Codex. It can also scaffold projects for Next.js, Expo, and Node.js tech stacks.

What does Lattice Project Builder generate?

Lattice Project Builder generates a PROJECT_GUIDE.md with architecture decisions and milestones, a version-locked compatible tech stack plan, custom AI rules for Cursor, Claude Code, GitHub Copilot, and Codex, GitHub Actions CI/CD workflows, and a single npx setup command. Supported stack combinations also get scaffolded files, while unsupported providers come with setup notes instead of silent substitutions.

Who is Lattice built for?

Lattice is built for solo founders, indie developers, and CS students who use AI coding assistants like Cursor, Claude Code, GitHub Copilot, or Codex. It's especially useful for developers who spend too much time on project setup instead of building.
