I’ve been using various contact managers but they all feel like sales tools, so I built Nametag to track the people I actually care about - friends, family, colleagues. It maps relationships, tracks birthdays, and visualizes your network as an interactive graph.

Self-hosting highlights:

• Docker Compose setup - PostgreSQL, Redis, Next.js app. One command to start
• No email service needed - Accounts auto-verify, works completely offline
• Unlimited contacts - No artificial limits (hosted version caps free tier at 50)
• Complete data ownership - Your relationship data stays on your infrastructure
• Optional email - Can configure Resend if you want birthday/reminder emails
• No phone-home - Runs entirely on your network if you want
• AGPL-3.0 licensed - Full source access

Features:

• Track people with flexible attributes (name, birthday, contact info, notes)
• Map relationships between people (family, friends, colleagues, custom types)
• Interactive D3.js network graph visualization
• Custom groups for organizing contacts
• Birthday reminders (if you configure email)
• Dark mode, i18n (English and Spanish for now, but more are coming)
• Mobile-responsive

Tech stack:

• Next.js 16 (TypeScript)
• PostgreSQL + Prisma ORM
• Redis for rate limiting
• D3.js for graph visualization
• Tailwind CSS

Quick start:

git clone https://github.com/mattogodoy/nametag
cd nametag
# Edit .env with your secrets
docker-compose up -d

Database migrations run automatically on first start.

Access at localhost:3000.

There’s also a hosted version at https://nametag.one/ if you don’t want to self-host (helps fund development).

Happy to answer questions about the setup, architecture, or deployment!
