What AB Tasty does well

Bayesian engine with revenue analysis, plus an optional frequentist mode (docs.abtasty.com).
Web experimentation and feature experimentation (formerly Flagship) (docs.abtasty.com).
Strong in European retail and e-commerce (wingify.com/news/vwo-and-ab-tasty-combine).

What Duelpilot does well

Your own agent does the research, design, checks and monitoring over MCP (48 tools); no AI bill from Duelpilot.
A person approves every launch: no MCP tool can approve, launch, pick a winner or ship.
Always-valid sequential statistics (mSPRT) with Holm correction, sample-ratio-mismatch checks and guardrail metrics.
Every variant gets a preview link and a site check on phone, tablet and desktop before anyone can approve it.
Flat price per site, published, from €9/month, and your first test is free on every plan; no visitor meters.

Where Duelpilot falls short

You need an AI agent that speaks MCP; without one there is no visual editor to build variants by hand.
No heatmaps or session recordings: Duelpilot counts results and sends variants to your own analytics.
A young product (2026): fewer integrations and a shorter track record than established tools.
