# 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.

## Which one should you choose?

### Choose Flint if…

## Try Duelpilot with your own agent

Give your agent one line: [set up Duelpilot for my site using /agents.md](https://duelpilot.com/agents.md). It opens a workspace, installs and verifies the script, and drafts the first test; you approve what goes live.

## FAQ

### Is Flint an A/B testing tool?

Not primarily. Flint builds and publishes landing pages; its docs point to third-party tools for experiments. Duelpilot is an A/B testing tool and builds no pages.

### 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.
