Duelpilot vs VWO (Wingify)

Wingify, formed when VWO and AB Tasty combined in January 2026, is an experimentation, personalization and behavior-analytics suite for marketing, CRO and product teams. Duelpilot is A/B testing run by your own AI agent over MCP, with a person approving every launch. Both can be used by an AI agent over MCP. The biggest difference is who launches: in VWO (Wingify) an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). VWO (Wingify) doesn't publish its prices; Duelpilot is a flat, published price per site, with your first test free on every plan.

What VWO (Wingify) does well

  • Broad suite: web testing, feature experimentation, personalization and behavior analytics (wingify.com/pricing).
  • Two official MCP servers: one for web testing (A/B and split URL) and one for feature flags (help.wingify.com, developers.wingify.com).
  • Bayesian reporting with an option for sequential testing (wingify.com/pricing).
  • AI Autopilot can act on live tests within configured guardrails (Wingz Advanced) (wingify.com/pricing).

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.

Choose VWO/Wingify if you want one enterprise suite for testing, personalization, heatmaps, recordings and surveys, with a large vendor behind it and AI that can act within guardrails.

How Duelpilot works

Try Duelpilot with your own agent

Give your agent one line: set up Duelpilot for my site using /agents.md. It opens a workspace, installs and verifies the script, and drafts the first test; you approve what goes live. Try your first test free or see pricing.
