Duelpilot vs Flint

A managed landing-page platform (ad, ABM and GEO pages) that Claude can drive over MCP to create, edit and publish pages, for B2B marketing and growth teams. 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 Flint an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Flint is priced quote only; Duelpilot is flat per site, without AI credits.

What Flint does well

Claude can create, edit and publish pages through a 4-tool MCP server (run_background_agent, check_background_agent_status, list_sites, publish_site) (flint.com/docs/claude-mcp).
Bulk and personalized pages from lists such as Clay or Airtable (flint.com/product/flint-mcp).
Pages match your brand by capturing your site's design system (flint.com/product).

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.

Flint website

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 Claude publish with Flint?

Yes: Flint's MCP has a publish_site tool. In Duelpilot no agent can launch or ship; agents propose and people approve.

Can I A/B test Flint pages with Duelpilot?

Yes, if you can add Duelpilot's script tag to the page; Duelpilot works on any page a browser renders.
