Convex vs Electric Sql

Convex scores higher on the AgentReady, 61/100 against 42/100. They differ on 7 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.

Electric Sql. Electric is an agent platform built on sync, providing managed agents, streams, and a sync engine for building multi-agent systems and local-first apps.

Where Convex is ahead

Convex passes clear canonical domain and clear product positioning, and Electric Sql 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 and agent-compatible signup flow. Electric Sql misses those.

And on operate, retry behavior documented, observable execution and agent compatibility verified. Electric Sql misses those.

What neither does

Both fail mcp discoverable, structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, programmatic credential creation, mcp integration available, 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. Convex leads 87 to 67. Convex misses mcp discoverable; Electric Sql misses clear canonical domain, clear product positioning, mcp discoverable.

Understand. Both sit at 23/100 here. Convex misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented; Electric Sql misses structured api reference, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented.

Adopt. Convex leads 76 to 55. Convex misses programmatic credential creation, mcp integration available; Electric Sql 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. Convex leads 59 to 24. Convex misses structured, predictable output, machine-readable errors, idempotency support, rate-limit behavior predictable; Electric Sql misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified.

Pricing

Convex starts at $0/mo and has a free tier. Electric Sql starts at $1 per 1M writes and has a free tier.

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 Electric Sql. Alternatives to each: Convex, Electric Sql.
