Duelpilot vs Webflow Optimize

AI-assisted A/B testing and personalization (formerly Intellimize), sold as a Webflow add-on and also usable on non-Webflow sites via a script, for marketing teams. Duelpilot is A/B testing run by your own AI agent over MCP, with a person approving every launch. Webflow Optimize's agent access is limited (Webflow's MCP can read Optimize experiments and results (announced 15 Oct 2026); no write access). Webflow Optimize is priced by traffic (visitors or users); Duelpilot is flat per site, without AI credits.

Prices as published by each vendor on the date checked, excluding VAT. Duelpilot has no visitor meters and no AI credits: the AI runs in your own agent's subscription.

What Webflow Optimize does well

AI Optimize serves the best variation per visitor in real time (webflow.com/feature/optimize).
Firmographic targeting with Demandbase and 6sense (webflow.com/feature/optimize).
Native to Webflow, and usable on other sites via a JavaScript snippet (webflow.com/feature/optimize).

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.
