Duelpilot vs Convert
Convert Experiences: A/B, multivariate, split-URL and full-stack testing with published prices and an official MCP server, for CRO teams and agencies. 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 Convert an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Convert is priced by traffic (visitors or users); Duelpilot is flat per site, without AI credits.

What Convert does well
- Three statistics engines (fixed-horizon frequentist, sequential, Bayesian), switchable on a running test (convert.com/features).
- Published prices and no features sold as separate modules (convert.com/pricing).
- Official MCP server on all paid plans, read-only by default, with drafts, confirmations and an approval-request namespace (convert.com/mcp-server).
- Client-side and full-stack testing with six SDKs (convert.com/features).
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.
Which one should you choose?
Choose Convert if…
Choose Convert if you run a CRO programme or agency that wants a full visual editor, multivariate and full-stack tests, a choice of statistics engines and a mature, privacy-minded vendor with published prices.
Choose Duelpilot if…
Choose Duelpilot if you would rather have your own agent do the research, design and site checks than work in a visual editor, at €49 per site per month flat instead of a tested-user meter, with your first test free on every plan.
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
How many tools does Convert's MCP have?
Convert describes 16 top-level tools with 113 callable actions when full access is enabled; by default the local server starts in read-only reporting mode (checked 17 Oct 2026).
Can an agent launch a Convert test?
Only with full access and with explicit confirmation for activating or pausing; new work starts as a draft. In Duelpilot no agent can launch at all; a person approves, or an owner's autopilot policy within guardrails.
Are both tools' statistics safe to peek at?
Convert offers a sequential engine as one of three options; Duelpilot always uses an always-valid sequential test (mSPRT) with Holm correction and SRM checks.
How do the prices compare?
Convert Growth is $399/month ($299 billed annually) for 100K tested users. Duelpilot Pro is €49/month (€39 yearly) per site with no visitor meter (fair use 2M pageviews).
