What Cloudflare does that Uploadthing does not
Cloudflare passes clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata, structured api reference, cli available, mcp integration available, agent compatibility verified, and Uploadthing 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
Uploadthing fails clear product positioning, llms.txt published, llms-full.txt / full agent docs, mcp discoverable, machine-readable metadata, structured api reference, 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, official python sdk, cli available, mcp integration available, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
