Categories

Packages are organized into 7 categories:

• Cryptography — Hashing, encryption, signatures, and crypto primitives
• Data Structures — Trees, arrays, sets, and other data structures
• Math — Mathematical operations, number theory, and field arithmetic
• Utilities — General-purpose helper libraries and tools
• Zero Knowledge — ZK proof helpers, verifiers, and proof-system utilities
• Circuits — Reusable circuit components and gadgets
• Standards — Implementations of standards (EIP, BIP, RFC, etc.)

CLI Tool

Install the CLI to manage packages directly in your Noir projects:

cargo install nargo-add

Commands:

# Add a package (updates Nargo.toml automatically)
nargo add package-name

# Remove a package
nargo remove package-name

# Remove multiple packages
nargo remove pkg-one pkg-two

# Remove and clean cached source files
nargo remove package-name --clean

See cli-tool/README.md for full CLI documentation.

Local Development

Requirements: Rust, Node.js, PostgreSQL (or a Supabase project)

Backend:

cd server
cp .env.example .env   # fill in DATABASE_URL and GITHUB_TOKEN
cargo run
# Runs on http://localhost:3001

Frontend:

cd frontend
npm install
npm run dev
# Runs on http://localhost:3000

Both must run simultaneously. The frontend proxies /api/* to the backend automatically.

Run migrations:

cd server
sqlx migrate run

Tech Stack

• Backend: Rust + Axum + SQLx + PostgreSQL
• Frontend: Next.js 16 + Tailwind CSS
• Database: Supabase (PostgreSQL) with pg_trgm indexes for fast search
• Hosting: Railway (backend) + Vercel (frontend)
