Duelpilot vs Mida

A lightweight A/B testing and feature-flag tool with AI variant generation (MidaGX) and an MCP server, for SMB 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 Mida an agent can start tests itself, in Duelpilot a person approves (or an owner's autopilot policy, within guardrails). Mida 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 Mida does well

Free Sandbox plan with 100,000 MTU and 3 live tests (mida.so/pricing).
MCP with 59 tools covering the whole loop: create, preview, launch, results and serving the winner (mida.so/mcp).
Bayesian, frequentist or sequential analysis (mida.so/changelog).
Feature flags with server-side and mobile SDKs (mida.so/changelog).

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 Mida if…

Choose Mida if you want a light script, a generous free tier, feature flags with mobile SDKs and an MCP that can take a test all the way from draft to serving the winner.

Mida website

Choose Duelpilot if…

Choose Duelpilot if you want real-browser site checks (including a click-through interaction check) before anything can go live, a person approving every launch, and €49 per site flat instead of $224 per month.

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 Mida's MCP launch tests?

Yes. Tests start as drafts, and launching and serving the winner are MCP actions (checked 17 Oct 2026). Duelpilot's MCP cannot launch or ship.

Do both have a free plan?

Mida does: Sandbox includes 100,000 MTU and 3 live tests with 30 AI credits. Duelpilot has no free plan; your first test is free on every plan and Starter (one site, one live test) is €9/month, with no AI credits needed because AI runs in your agent.

Which has better statistics?

Both offer sequential analysis. Mida lets you choose Bayesian, frequentist or sequential; Duelpilot always uses mSPRT with Holm correction, SRM checks and guardrails.

How do paid prices compare?

Mida Growth is $224/month billed annually; Duelpilot Pro is €49/month (€39 yearly) per site.
