Hanko vs Supabase

Supabase scores higher on the AgentReady, 74/100 against 48/100. They differ on 19 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Hanko. Hanko is an open-source authentication and user management platform for modern web and mobile apps.

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 Hanko is ahead

Hanko passes search discoverable, 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, free trial or free allowance, fast time to first request, copyable quickstart, official typescript sdk and official python sdk. Supabase misses those.

Finally, on operate, canonical workflow succeeds, structured, predictable output and observable execution. Supabase misses those.

Where Supabase is ahead

Supabase passes clear product positioning and mcp discoverable, and Hanko does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds understand: structured api reference and authentication documented. Hanko misses those.

And on adopt, cli available and mcp integration available. Hanko misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, no mandatory sales call, programmatic credential creation, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, 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 73. Hanko misses clear product positioning, mcp 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. Hanko 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. Supabase leads 63 to 50. Hanko misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available; 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 47. Hanko misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, 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.
