CockroachDB vs Supabase
Supabase scores higher on the AgentReady, 74/100 against 51/100. They differ on 12 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.
What each one is
CockroachDB. CockroachDB is a cloud-agnostic, PostgreSQL compatible database built for modern applications delivering unmatched uptime, scale and compliance anywhere in the world.
Supabase. Supabase is an open-source Firebase alternative that provides a complete backend platform built on top of Postgres, offering database, authentication, storage, realtime, edge functions, and vector capabilities.
Where CockroachDB is ahead
CockroachDB passes clear canonical domain and public docs discoverable, and Supabase does not. That is discover, whether an agent can find the product at all without being told it exists.
It also holds understand: pricing understandable. Supabase misses it.
And on adopt, self-service signup, no mandatory sales call, free trial or free allowance, fast time to first request, copyable quickstart and official typescript sdk. Supabase misses those.
Finally, on operate, canonical workflow succeeds. Supabase misses it.
Where Supabase is ahead
Supabase passes structured api reference and authentication documented, and CockroachDB does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.
What neither does
Both fail search discoverable, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, official python sdk, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified. 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. Supabase leads 100 to 87. CockroachDB misses search discoverable; Supabase misses search discoverable, clear canonical domain, public docs discoverable.
Understand is whether an agent can read the docs and work out how the API behaves before calling it. Supabase leads 67 to 23. CockroachDB misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Supabase misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.
Adopt. CockroachDB leads 71 to 63. CockroachDB misses agent-compatible signup flow, programmatic credential creation, official python sdk; Supabase misses self-service signup, no mandatory sales call, programmatic credential creation, free trial or free allowance, fast time to first request, copyable quickstart, official typescript sdk, official python sdk.
Operate. Supabase leads 67 to 24. CockroachDB misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; Supabase misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.
Pricing
