Supabase vs Unkey

Supabase scores higher on the AgentReady, 74/100 against 56/100. They differ on 16 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.

Unkey. Unkey is a developer platform for modern APIs that unifies infrastructure, allowing developers to deploy APIs instantly, route traffic through global gateways, and understand usage in one place.

Where Supabase is ahead

Supabase passes llms-full.txt / full agent docs and mcp discoverable, and Unkey does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: mcp integration available. Unkey misses it.

Where Unkey is ahead

Unkey 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 and limits / constraints documented. Supabase misses those.

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 and observable execution. Supabase misses those.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, no mandatory sales call, programmatic credential creation, structured, predictable output, 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 80. Supabase misses search discoverable, clear canonical domain, public docs discoverable; Unkey misses llms-full.txt / full agent docs, mcp discoverable.

Understand. Supabase leads 67 to 54. Supabase misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Unkey misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented.

Adopt. Supabase leads 63 to 55. 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; Unkey misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, mcp integration available.

Operate is whether an agent can run against it in production and recover when a call fails. Supabase leads 67 to 35. 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; Unkey misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

Supabase does not publish a machine-readable starting price. Unkey starts at $5/mo and has a free tier.
