Why bit?

It is feature-complete by design. Its strength lies in simplicity, a reliable URL shortener without unnecessary bloat. Bug fixes will continue, but new features aren't planned.

• 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.
• Flexible request forwarding system passes client context to destinations via standard X-Forwarded-For and User-Agent headers, enabling advanced tracking and integration capabilities when needed.
• Multiple users are supported via API key authentication. Create, list and delete via the CLI.
