Convex vs Neon

Neon scores higher on the AgentReady, 90/100 against 61/100. They differ on 15 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

Convex. The reactive backend platform that keeps up with you and your agents.

Neon. The backend for apps and agents, built to scale on Lakebase Postgres.

Where Convex is ahead

Convex passes search discoverable and public docs discoverable, and Neon does not. That is discover, whether an agent can find the product at all without being told it exists.

It also holds adopt: no mandatory sales call, free trial or free allowance, fast time to first request, copyable quickstart, official typescript sdk and official python sdk. Neon misses those.

And on operate, canonical workflow succeeds, retry behavior documented and observable execution. Neon misses those.

Where Neon is ahead

Neon passes mcp discoverable, and Convex 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. Convex misses those.

And on adopt, mcp integration available. Convex misses it.

What neither does

Both fail openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable. 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. Neon leads 100 to 87. Convex misses mcp discoverable; Neon misses search discoverable, public docs discoverable.

Understand is whether an agent can read the docs and work out how the API behaves before calling it. Neon leads 83 to 23. Convex misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Neon misses openapi / spec quality, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Neon leads 100 to 76. Convex misses programmatic credential creation, mcp integration available; Neon misses 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. Neon leads 78 to 59. Convex misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable; Neon misses canonical workflow succeeds, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution.

Pricing

Convex starts at $0/mo and has a free tier. Neon does not publish one.

Signal by signal

Which to pick

Convex clears more of the signals an agent needs, so it is the safer default for unattended use. Full profiles: Convex and Neon. Alternatives to each: Convex, Neon.
