Bit

Features

• Minimal tracking setup: Country, browser, OS, referer. No cookies or persistent tracking mechanisms are used beyond what's available from a basic client's request.
• Includes X-Forwarded-For header.
• Multiple users are supported via API key authentication. Create, list and delete keys via the CLI.
• Easy to extend, Ruby on Rails inspired setup.
• Auto update UA regexes and GeoLite2 database.

Why bit?

Fast: 11k req/sec, latency 11ms, 40MiB avg memory usage (100k requests using 125 connections, benchmark).

Lightweight: Minimal dependencies, image size under 20 MiB, memory usage under 60 MiB at peak.

Self-hosted: Dokku, Docker Compose.

Production ready: Feature-complete by design, simple and reliable without unnecessary bloat. Bug fixes will continue, but new features aren't planned.

Dokku

• Dockerfile

FROM sjdonado/bit

• Over ssh

dokku apps:create bit

dokku domains:set bit bit.yourdomain.com
dokku letsencrypt:enable bit

dokku storage:ensure-directory bit-sqlite
dokku storage:mount bit /var/lib/dokku/data/storage/bit-sqlite:/usr/src/app/sqlite/

Dokku (subnetwork)

Recommended for lower latency communication (no host network traversal)

  dokku network:create bit-net
  dokku network:set bit attach-post-create bit-net
  dokku network:set myapp attach-post-create bit-net
