Duelpilot vs Tailor

"Agentic growth" for websites: agents study visitors, ads and competitors, then build A/B tests, personalized pages and hosted landing pages, for performance marketers, growth 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 Tailor an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Tailor is priced by traffic (visitors or users); Duelpilot is flat per site, without AI credits.

source

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 Tailor does well

Targeting by campaign, keyword, UTM, traffic source, device and location, tied to ad accounts (tailorhq.ai/integrations/mcp).
MCP exposes the same tools as Tailor's own in-app agent, including previews and results (tailorhq.ai/integrations/mcp).
Results measured down to signups, pipeline and revenue; performance-based offer on first landing-page tests (tailorhq.ai).

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 Tailor if…

Choose Tailor if your traffic is mostly paid and you want landing pages personalized per campaign, keyword or account, with results tied to pipeline and revenue.

Tailor website

Choose Duelpilot if…

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 Tailor's MCP launch tests?

It can, if you allow it: Tailor says launch can be open to agents or reserved for humans. Duelpilot has no launch tool at all; launches come from a person or an owner's autopilot policy within guardrails.

Is Tailor's MCP on every plan?

MCP and API are listed from the Pro plan, which is custom-priced (checked 17 Oct 2026). Duelpilot's MCP is on every plan, including Starter (€9/month).

What drives Tailor's price?

Tailored page visitors and identified-visitor credits, from $250/month on Basic. Duelpilot is flat per site with no visitor meter (fair use applies).

Does Duelpilot personalize pages per ad campaign?

Duelpilot targets tests by URL, device, source/UTM, referrer and more, but it is an A/B testing tool, not a per-account personalization engine. For ad-to-page personalization Tailor is the more specialised tool.
