| An agent can launch tests without a person | No — A person approves every launch; an owner can switch on an autopilot policy with guardrails, never an agent.

| Server-side / code experiments | Yes — Code plan only: your agent builds the arms in your repo behind Duelpilot flags. [source](https://duelpilot.com/agents.md) | Yes — Feature Experiment with SDKs and flags. [source](https://amplitude.com/pricing) |
| Sequential (peek-safe) statistics | Yes — mSPRT: always-valid p-values, safe to check daily. [source](https://duelpilot.com/index.md) | Yes — mSPRT sequential testing is the default. [source](https://amplitude.com/docs/feature-experiment/under-the-hood/experiment-sequential-testing) |
| Charges for AI usage / credits | No — The AI runs in your own agent's subscription. [source](https://duelpilot.com/pricing.md) | No — AI Agents and MCP included on all plans; agent-analytics sessions are capped per plan. [source](https://amplitude.com/pricing) |
| Free plan | No — No free plan; your first test is free on every plan, Starter from €9/month. [source](https://duelpilot.com/pricing.md) | Partly — Free plan exists, but with 1 active experiment per type and no experiment results on Free or Plus. [source](https://amplitude.com/pricing) |

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 Amplitude Experiment does well

- Experiments and product analytics in one place (amplitude.com/pricing).
- Sequential testing (mSPRT) by default, with T-test and CUPED options (amplitude.com/docs).
- Hosted MCP server with experiment and flag tools; AI Agents and MCP on all plans (amplitude.com/docs/amplitude-ai/amplitude-mcp).

## 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 Amplitude Experiment if…

Choose Amplitude Experiment if you already use Amplitude for product analytics and want experiments, flags and analysis in the same platform.

## 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

### Does Amplitude's free plan include experiment results?

No. Amplitude's pricing page lists experiment results only on custom Growth and Enterprise plans (checked 17 Oct 2026). Duelpilot shows results on every plan, from Starter at €9/month.

### Do both use sequential statistics?

Yes. Amplitude defaults to mSPRT; Duelpilot also uses mSPRT, plus Holm correction, SRM checks and guardrails.

### Can I use Duelpilot with Amplitude?

Yes. Duelpilot sends variant exposure events to Amplitude, so you can analyse tests in Amplitude too.
