Agent0 alternative to Optimizely
Run A/B tests without the five-figure Optimizely contract.
Optimizely starts around $36k/year for mid-market. The A/B Test Setup skill designs the same experiments — hypothesis, sample size math, variant copy, tracking plan — for the cost of Agent0 Starter.

Why Agent0
You do not actually need a platform to run an A/B test. You need a rigorous design, clean instrumentation, and an honest read on the results. Optimizely bundles those into a product. Agent0 ships them as a skill your agents run, wired to whatever tracking stack you already have.
