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!

    Congratulations on the launch! Could this also be used as a genealogy tree? I’ve been wanting for a long time to create mine but the options I found were too expensive and I wasn’t up to create it from scratch (too long and not future proof).

      Thank you! Yes, I’ve thought about this and it’s in my roadmap to create an “export group as family tree to PDF” function. Would that be good enough for your needs?

      Ugh, also looking for a way to digitalize mine, but all tools I’ve found are either way too complex or lack critical functions, like e. g. supporting patchwork families/split-up parents which have new children.
