Keitaro runs on your own server and ships with a built-in landing page editor, which makes it unusually self-contained for a self-hosted product - you can build, serve, and measure landers from inside the same tool. Its bot database refreshes on a two-week cycle, keeping junk click rates down without requiring manual configuration. The campaign rule engine supports multi-level traffic distribution across geos, devices, ISPs, and custom parameters.
The per-server license model is affordable for solo buyers but gets complicated when scaling across multiple server regions.
