GrowthBook vs Split

GrowthBook scores higher on the AgentReady, 67/100 against 45/100. They differ on 9 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.

Split. Split is a feature management and experimentation platform that helps engineering teams move faster by creating, targeting, and managing feature flags at enterprise scale.

Where GrowthBook is ahead

GrowthBook passes llms-full.txt / full agent docs and mcp discoverable, and Split 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. Split misses it.

And on adopt, self-service signup, fast time to first request and mcp integration available. Split misses those.

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

Where Split is ahead

Split passes agent-compatible signup flow, and GrowthBook does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

What neither does

Both fail clear product positioning, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, 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 67. GrowthBook misses clear product positioning; Split misses clear product positioning, llms-full.txt / full agent docs, mcp discoverable.

Understand. GrowthBook leads 46 to 31. GrowthBook misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Split misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. GrowthBook leads 70 to 45. GrowthBook misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation; Split misses self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, 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; Split misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

GrowthBook does not publish a machine-readable starting price and has a free tier. Split does not publish one and has a free tier.
