GrowthBook vs Heap

GrowthBook scores higher on the AgentReady, 67/100 against 42/100. They differ on 11 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

GrowthBook. The warehouse-native platform used by modern product teams for experimentation, feature flags, and product analytics.

Heap. Heap is a digital analytics platform that automatically captures every user interaction to help companies understand customers' end-to-end journeys, improve conversion and activation, increase retention, and deliver great user experiences.

Where GrowthBook is ahead

GrowthBook passes public docs discoverable, llms.txt published, llms-full.txt / full agent docs and mcp discoverable, and Heap 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 and authentication documented. Heap misses those.

And on adopt, cli available and mcp integration available. Heap misses those.

Finally, on operate, structured, predictable output and agent compatibility verified. Heap misses those.

Where Heap is ahead

Heap passes clear product positioning, and GrowthBook does not. That is discover, whether an agent can find the product at all without being told it exists.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. 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. GrowthBook leads 87 to 60. GrowthBook misses clear product positioning; Heap misses public docs discoverable, llms.txt published, llms-full.txt / full agent docs, mcp discoverable.

Understand. GrowthBook leads 46 to 23. GrowthBook misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Heap misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. GrowthBook leads 70 to 50. GrowthBook misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Heap misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available.

Operate is whether an agent can run against it in production and recover when a call fails. GrowthBook leads 65 to 35. GrowthBook misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Heap misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.
