Crawlbase vs Uploadthing

Crawlbase scores higher on the AgentReady, 68/100 against 40/100. They differ on 13 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Crawlbase. Crawlbase provides web crawling, scraping, and parsing APIs at scale.

Uploadthing. UploadThing is a file upload service for developers, positioned as an easier and safer alternative to AWS S3.

Where Crawlbase is ahead

Crawlbase passes clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable and machine-readable metadata, and Uploadthing does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: limits / constraints documented. Uploadthing misses it.

And on adopt, agent-compatible signup flow, official python sdk, cli available and mcp integration available. Uploadthing misses those.

Finally, on operate, observable execution and agent compatibility verified. Uploadthing misses those.

Where Uploadthing is ahead

Uploadthing passes structured, predictable output, and Crawlbase does not. That is operate, whether an agent can run against it in production and recover when a call fails.

What neither does

Both fail structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes 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 is whether an agent can find the product at all without being told it exists. Crawlbase leads 100 to 53. Crawlbase misses nothing; Uploadthing misses clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata.

Understand. Crawlbase leads 38 to 31. Crawlbase misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented; Uploadthing misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Crawlbase leads 81 to 40. Crawlbase misses no mandatory sales call, programmatic credential creation; Uploadthing misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, official python sdk, cli available, mcp integration available.

Operate. Crawlbase leads 53 to 35. Crawlbase misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable; Uploadthing misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.

Pricing

Crawlbase does not publish a machine-readable starting price and has a free tier. Uploadthing starts at $0/month and has a free tier.
