Duelpilot vs ABConvert

A Shopify A/B testing app for price, shipping, theme, template, URL, offer and checkout tests, with a beta MCP server, for Shopify merchants. Duelpilot is A/B testing run by your own AI agent over MCP, with a person approving every launch. ABConvert's agent access is limited (In beta, opt-in via support, Growth plan and above). The biggest difference is who launches: in ABConvert an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). ABConvert is priced by usage; 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 ABConvert does well

Seven Shopify test types including price, shipping and checkout (Shopify Plus) (docs.abconvert.io/mcp/overview).
MCP with 33 tools; the API token cannot delete tests (docs.abconvert.io/mcp/tools).
Overage charged per test order rather than whole-store volume (abconvert.io/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.

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.

Questions

Can Claude launch an ABConvert test?

Yes, its MCP tools include launch, pause, resume and end (beta). Duelpilot's MCP has no launch tool by design.

Does Duelpilot work on Shopify?

Yes, as a script tag on the theme; it changes what the browser shows. Price and checkout logic tests need a Shopify app like ABConvert, or Duelpilot's Code plan in your own code.

Which is cheaper?

ABConvert starts at $99/month with test-order limits; Duelpilot starts at €9/month (Starter, first test free) and is €49/month on Pro, flat per site.
