pagent review (2026): features, pros and cons, and what to check before you buy
An AI agent that proposes A/B test hypotheses, builds the variants in your site's design and runs them on your live site with human approval.
Our take for buyers
pagent fits e-commerce teams, CRO teams and agencies that want an AI agent to do the hypothesis and build work for A/B tests. It starts from your URL, proposes hypotheses, builds real-code variants in your brand's style and runs them on your live site through one script snippet. People approve each test by chat or email, or switch on autopilot, and results use Bayesian statistics with a recommended next step.
It runs alongside Optimizely, Kameleoon, VWO and AB Tasty rather than replacing them, and a hosted MCP server lets Claude, ChatGPT and coding agents read results and start tests. Pricing is a custom quote, based on monthly unique users, with a free trial available. There is no G2 rating yet and no formal security certification such as SOC 2, so ask for the DPA and security documentation before customer data flows in.
Pros
- Covers the loop from hypothesis to built variant, not only the testing engine.
- Every test needs human approval unless autopilot is switched on.
- Bayesian results with a plain recommended next step.
Cons
- No public list price, quote based on monthly unique users.
- No G2 rating yet, so little independent review data.
- No formal security certifications such as SOC 2 yet.
- Best for
- E-commerce and CRO teams with more test ideas than developer time.
- Starting price
- Custom quote, based on monthly unique users
