Supabase vs turbopuffer

Supabase scores higher on the AgentReady, 74/100 against 53/100. They differ on 18 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.

turbopuffer. turbopuffer is a fast, object-storage native search engine providing vector and full-text search built on object storage.

Where Supabase is ahead

Supabase passes mcp discoverable, and turbopuffer 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. turbopuffer misses those.

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

Where turbopuffer is ahead

turbopuffer passes search discoverable 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, 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.

What neither does

Both fail clear canonical domain, openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, 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 80. Supabase misses search discoverable, clear canonical domain, public docs discoverable; turbopuffer misses clear canonical domain, mcp 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. Supabase misses openapi / spec quality, pricing understandable, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; turbopuffer misses structured api reference, openapi / spec quality, authentication documented, 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; turbopuffer misses agent-compatible signup flow, programmatic credential creation, cli available, mcp integration available.

Operate. Supabase leads 67 to 47. 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; turbopuffer misses machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing
