That's 168ms -> 1.6ms! and we have a lot of good ideas how to make it even faster.
We've just delivered a 100x write performance bump with our latest release of Electric. How? We threw away our storage engine and built a new one designed for sync 🧵

Electric 1.1: new storage engine with 100x faster writes | ElectricSQL
How we built a new storage engine for Electric, why we did it now, and how it delivers lower latency, higher throughput, and zero‑downtime deploys.

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.

"plain HTTP, and a Postgres DB". Really nice example of how @electric-sql.com is really easy to integrate into your app.
I made this example of integrating BlockNote with Electric SQL today: github.com/TypeCellOS/b...
It shows the integration between Electric SQL, BlockNote & Y.js enabling collaborative editing using plain HTTP, and a Postgres DB.

PGlite (WASM Postgres) now gets over 1 million downloads a week! 🤯🚀
Absolutely incredible to see how people have embraced what we have built.
Awesome work by the team!

I've been working on a new Y.js synchronization server for the past few weeks now.
Today, I've hit a milestone for it, multiple clients synchronizing their documents & cursor updates!
I threw together a demo with blocknote.js.org and it works!

When you're vibe-coding, you don't want to think about infra. You want to stay in the zone, iterating and expressing yourself.
That means having a database inside your sandbox. No glue, no friction, no external services, no free-tier limits. Forkable, disposable, unlimited and zero cost.

🧵 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.

Sync allows building APIs with minimal contracts. Why does it matter? As AI accelerates software development beyond human speed, your APIs must evolve in seconds, not days. Only sync engines give you that flexibility.
We've recently launched Electric Cloud BETA. It's never been easier to try sync.

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.

Building AI apps? You need sync | ElectricSQL
AI apps are collaborative. Building them requires solving resumeability, interruptability, multi‑tab, multi‑device and multi‑user.

Had a great time last night.
- Many familiar faces, but a lot more newcomers
- people are exploring local first tech to solve problems they have
- with interests ranging low-level optimizations, to high-performance state management, this is a very rich and diverse community!

Looking forward for the 2nd local-first meetup in Berlin tonight. We have fantastic talks lined up including the authors of Yjs, ElectricSQL and Jazz.
Due to the surprising demand, we've upgraded the venue to provide extra space for additional guests.
