How to build agentic systems on real-time sync.
Agentic AI, beneath all the hype, is actually just normal software. You can build agentic systems with a database, standard web tooling and real-time sync.

That's 168ms -> 1.6ms! and we have a lot of good ideas how to make it even faster.

ElectricSQL recently completed a 120-day reliability sprint. Our one goal: make our sync engine so boring-reliable you stop thinking about it and just build.
We chased every incident, fixed every user-reported bug, and made unglamorous work our priority. 🧵

🧵 More play less infra => vibe coding with the database inside the sandbox.
Apps built with AI app builders like @bolt.new usually need to connect to a database to actually work. With @pglite.dev you can have the database inside the sandbox, so you can vibe code without even thinking about infra.

AI apps are inherently collaborative between users and agents. You can't just have the agent state in the cloud. You need to keep the users in the loop.
That means you need to build them on sync.
