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!
