Supabase vs SuperTokens

Supabase scores higher on the AgentReady, 74/100 against 54/100. They differ on 11 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

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.

SuperTokens. Open source user authentication platform that helps developers build fast, maintain control, and reduce costs.

Where Supabase is ahead

Supabase passes structured api reference, and SuperTokens does not. That is understand, whether an agent can read the docs and work out how the API behaves before calling it.

Where SuperTokens is ahead

SuperTokens 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, no mandatory sales call, free trial or free allowance, copyable quickstart, official typescript sdk and official python sdk. Supabase misses those.

Finally, on operate, canonical workflow succeeds. Supabase misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, self-service signup, programmatic credential creation, fast time to first request, 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. Both sit at 100/100 here. Supabase misses search discoverable, clear canonical domain, public docs discoverable; SuperTokens misses nothing.

Understand. Supabase leads 67 to 31. Supabase misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; SuperTokens misses structured api reference, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Supabase leads 63 to 60. 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; SuperTokens misses self-service signup, agent-compatible signup flow, programmatic credential creation, fast time to first request.

Operate is whether an agent can run against it in production and recover when a call fails. Supabase leads 67 to 24. 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; SuperTokens misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.

Pricing

Supabase does not publish a machine-readable starting price. SuperTokens starts at $0.02/MAU and has a free tier.
