Duelpilot vs Kameleoon

Web and feature experimentation for mid-market and enterprise teams, plus PBX (prompt-based experimentation) that builds variants from a chat prompt, with an official MCP server. 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 Kameleoon an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Kameleoon 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 Kameleoon does well

PBX builds variants from a prompt on most websites (docs.kameleoon.com).
MCP with full lifecycle control for experiments and feature flags (docs.kameleoon.com/mcp/mcp-server).
Frequentist, sequential and Bayesian methods plus CUPED (docs.kameleoon.com).
A published self-serve entry price for PBX (kameleoon.com/plans).

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 Kameleoon if…

Choose Kameleoon if you want an established web and feature experimentation platform with prompt-based variant building, a choice of statistical methods and enterprise options.

Kameleoon website

Choose Duelpilot if…

Choose Duelpilot if you want your own agent to write the variants without prompt credits, at €49 per site flat instead of $495 per month, and with no agent able to start a test.

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.

Does Kameleoon charge for AI?

PBX plans include 30, 100 or 200 prompt credits per month, about three per experiment. Duelpilot sells no AI; it runs in your own agent.

How do the entry prices compare?

Kameleoon PBX Starter starts at $495/month for up to 10 experiments and 50,000 MTU. Duelpilot Pro is €49/month per site with unlimited tests.

Do both support sequential statistics?

Yes. Kameleoon offers sequential testing as one method; Duelpilot always uses always-valid sequential statistics (mSPRT).
