Duelpilot vs Optibase

No-code A/B testing focused on Webflow (with a script for other builders), plus heatmaps, recordings and personalization, for Webflow teams and small marketing sites. Duelpilot is A/B testing run by your own AI agent over MCP, with a person approving every launch. Optibase's agent access is limited (MCP on all plans, but read-only). Optibase 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 Optibase does well

Native Webflow app plus a script for other builders (optibase.io).
Free plan with 10k tested users (optibase.io/pricing).
Heatmaps, recordings and personalization in the same tool (optibase.io).

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?

Optibase website

Choose Duelpilot if…

Choose Duelpilot if you want your agent to do more than read results: research, design 2–4 variants, run real-browser site checks and monitor, on Webflow or any other site.

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 my agent create Optibase tests?

No, Optibase's MCP is read-only (checked 17 Oct 2026). Duelpilot's agent can design and submit tests; a person approves them.

Do both have a free plan?

Optibase does: Free covers 10k tested users and one active test. Duelpilot has no free plan; your first test is free on every plan and Starter (one site, one live test) is €9/month.

Does Duelpilot have heatmaps?

No. Duelpilot deliberately records no visitors; pair it with Clarity or Hotjar, which it sends variant events to.
