Electric Sql vs Powersync

Powersync scores higher on the AgentReady, 50/100 against 42/100. They differ on 8 of the 41 signals. Which ones decides whether an agent can adopt them without a person watching.

What each one is

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.

Powersync. PowerSync is a sync engine that consists of two components: a service that enables high-scalability partial data syncing and a set of client SDKs that manage client-side persistence, consistency, reactivity and syncing write operations back.

Where Electric Sql is ahead

Electric Sql passes fast time to first request, copyable quickstart and official python sdk, and Powersync does not. That is adopt, whether an agent can get a key and make its first successful call without a human in the loop.

Where Powersync is ahead

Powersync 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, observable execution. Electric Sql misses it.

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, 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 is whether an agent can find the product at all without being told it exists. Powersync leads 87 to 67. Electric Sql misses clear canonical domain, clear product positioning, mcp discoverable; Powersync misses mcp discoverable.

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

Adopt. Both sit at 55/100 here. Electric Sql misses no mandatory sales call, agent-compatible signup flow, programmatic credential creation, mcp integration available; Powersync misses programmatic credential creation, fast time to first request, copyable quickstart, official python sdk, mcp integration available.

Operate. Powersync leads 35 to 24. Electric Sql misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution, agent compatibility verified; Powersync misses structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, agent compatibility verified.

Pricing

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