BeMob is one of the few cloud trackers with a genuinely usable free tier - up to 100,000 events per month at no cost - which makes it a natural starting point for buyers who want real attribution data before committing to a paid platform. The interface is clean, setup time is low, and it covers the core workflow: click tracking, postback conversions, offer rotation, and basic reporting. Fraud filtering is included across all plans.
The free plan is limited on data retention and custom domains; power buyers will outgrow it quickly, though the paid tiers remain reasonably priced.
