Crawlbase alternatives
The highest-scoring alternative to Crawlbase is Kernel at 89/100 on the AgentReady, against 68/100 for Crawlbase.
All scored in Proxy Infrastructure.
What Kernel does that Crawlbase does not
Kernel passes structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, programmatic credential creation, structured, predictable output, machine-readable errors, retry behavior documented, rate-limit behavior predictable, and Crawlbase 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
Crawlbase fails structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where Crawlbase loses the points
| Pillar | Crawlbase | What it measures |
|---|---|---|
| Discover | 100 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 38 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 81 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 53 | Rate-limit headers, errors, status, and behaviour under load. |
Crawlbase is weakest on understand at 38/100. 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, Crawlbase may still be the right pick.
What an agent runs into with Crawlbase
These are the findings from the last audit on 2026-09-01. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- 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.
- Add request examples to your API reference.
- Add response examples to your API reference.
- Support an Idempotency-Key so retries are safe.
