Split alternatives
The highest-scoring alternative to Split is GrowthBook at 67/100 on the AgentReady, against 45/100 for Split.
All scored in Feature Flags.
What GrowthBook does that Split does not
GrowthBook passes llms-full.txt / full agent docs, mcp discoverable, structured api reference, self-service signup, fast time to first request, mcp integration available, structured, predictable output, agent compatibility verified, and Split fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
Split fails clear product positioning, llms-full.txt / full agent docs, mcp discoverable, structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, programmatic credential creation, fast time to first request, mcp integration available, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Split loses the points
| Pillar | Split | What it measures |
|---|---|---|
| Discover | 67 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 31 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 45 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 35 | Rate-limit headers, errors, status, and behaviour under load. |
Split is weakest on understand at 31/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, Split may still be the right pick.
What an agent runs into with Split
These are the findings from the last audit on 2026-08-23. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Make signup self-serve; an agent cannot sit through a sales call.
- Ship an MCP server so agents can call you as a tool.
- Publish MCP install instructions so agents can discover the server.
- Publish an OpenAPI spec so agents can generate a client.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
