# 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.

### 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.

## FAQ

### Can an agent start a Kameleoon experiment?

Yes. Kameleoon's MCP tool experiment\_lifecycle\_update can start experiments; only stop and delete need a confirmation (checked 17 Oct 2026). Duelpilot has no launch tool.

### 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).
