The bottom line
VWO is a mature, full-featured platform with heatmaps, recordings, and personalization — capabilities that Otter A/B doesn't offer. If you need a complete optimization suite, VWO is a strong choice.
Where Otter A/B wins is simplicity and cost. VWO's MTU-based pricing means costs scale with your traffic — third-party estimates put the Growth plan at $200+/mo, with Pro and Enterprise tiers climbing significantly from there. Exact pricing isn't publicly listed. Otter A/B publishes all pricing and charges a flat rate per project.
For teams that need focused A/B testing without the overhead of a full optimization suite, Otter A/B offers a faster, simpler, and more affordable path.
