Adobe alternatives
The highest-scoring alternative to Adobe is Vellum at 88/100 on the AgentReady, against 51/100 for Adobe.
All scored in Agent Frameworks & Runtimes.
What Vellum does that Adobe does not
Vellum passes public docs discoverable, llms.txt published, openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, structured, predictable output, machine-readable errors, retry behavior documented, and Adobe 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
Adobe fails public docs discoverable, llms.txt published, openapi / spec quality, authentication documented, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, no mandatory sales call, agent-compatible signup flow, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, 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.
