Amplitude vs Plausible

Amplitude scores higher on the AgentReady, 83/100 against 48/100. They differ on 23 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Amplitude. Amplitude is a product analytics platform that helps teams understand user behavior, run experiments, and build better products.

Plausible. Plausible Analytics is a simple, privacy-friendly alternative to Google Analytics.

Where Amplitude is ahead

Amplitude passes llms.txt published, llms-full.txt / full agent docs and mcp discoverable, and Plausible does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented and limits / constraints documented. Plausible misses those.

And on adopt, programmatic credential creation, copyable quickstart, official python sdk, cli available and mcp integration available. Plausible misses those.

Finally, on operate, structured, predictable output, machine-readable errors, rate-limit behavior predictable and agent compatibility verified. Plausible misses those.

Where Plausible is ahead

Plausible passes search discoverable, and Amplitude does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: pricing understandable. Amplitude misses it.

And on adopt, self-service signup, no mandatory sales call and free trial or free allowance. Amplitude misses those.

What neither does

Both fail fast time to first request, retry behavior documented, idempotency support. If your agent needs any of those, you will be building it yourself either way.

Score, pillar by pillar

The AgentReady splits into four pillars, scored separately, because a product can be easy to find and still impossible to adopt.

Discover. Amplitude leads 87 to 73. Amplitude misses search discoverable; Plausible misses llms.txt published, llms-full.txt / full agent docs, mcp discoverable.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Amplitude leads 92 to 31. Amplitude misses pricing understandable; Plausible misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Amplitude leads 65 to 52. Amplitude misses self-service signup, no mandatory sales call, free trial or free allowance, fast time to first request; Plausible misses programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, cli available, mcp integration available.

Operate. Amplitude leads 88 to 35. Amplitude misses retry behavior documented, idempotency support; Plausible misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Amplitude does not publish a machine-readable starting price. Plausible starts at $9/mo with no free tier.

Signal by signal

Which to pick

Amplitude clears more of the signals an agent needs, so it is the safer default for unattended use. Full profiles: Amplitude and Plausible. Alternatives to each: Amplitude, Plausible.
