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.

Dev tools coming soon to @tanstack.com DB! The best client side state libs have brilliant dev tools, this is even more important for DB as you store so much state in it. The DB dev tools will give you full visibility of all collections and live queries. 🚀🎉

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. 🧵

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!

Not long now! lu.ma/sync-london Talks are shaping up great and we’re well past venue capacity. @yonz.bsky.social is airborne. @samwillis.uk has sorted out the pineapple cubes and cocktail sausages. If you’re in London on Tuesday and have been lurking so far, now’s your last chance!

Sync London · Luma

Interesting in building products on a local-first / sync engine architecture? Come along to the first Sync London, a meetup to learn and talk about better ways…

This is an incredibly niche take, even for my corner over here. It goes further, the iterate method computing a fixed point is referenced as "Limbo" in Inception. IYKYN 😂

Christopher Nolan's Inception is actually an allegory for Differential Dataflow 🤯 - Multidimensional Versioning = Nested Dream Timelines: as you iterate / move down you make a new timeline - Frontiers = Kick Timing: a reference point across all dimensions

I'm speaking about syncing Postgres into the client with @electric-sql.com at the SF Bay Area Postgres users groups tomorrow (Tuesday 10th June). Online from noon local time, live stream here: www.meetup.com/postgresql-1...

"Syncing Postgres into the Client" with James Arthur, Tue, Jun 10, 2025, 12:00 PM | Meetup

Join us virtually on Tuesday, June 10th for "Syncing Postgres into the Client" with James Arthur. Postgres has binary and logical replication for syncing data between repl

🧵 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.

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.

PGlite can now be used with any Postgres client, and pairs perfectly with AI app builders for vibe coding. Love that with @bolt.new *everything* runs in the browser - node, the dev server, and now even PGlite 🚀🤯 Awesome job by the team to get this out!

What to chat sync engines and how they can help you make better apps, particularly AI apps? We're hosting Sync London on July 1st, do sign up and come along. It will be a great evening! I'll be there ready to chat about @electric-sql.com, @pglite.dev and @tanstack.com DB.

Interested in building on sync? In London or SF? Come along to Sync London on July 1st lu.ma/sync-london -- we're co-organising with @anselm.io and @yonz.bsky.social, great speakers including @irltopper.bsky.social and @triggerdev.bsky.social

Really looking forward to @localfirstconf.com tomorrow. The world of software has changed more than we could have imagined since the conf a year ago. I'm excited to hear how everyone is thinking about local first software in this new AI world. 🚀🤖

Sam Willis@samwillis.uk · last yr.

GenAI enables me to try so many more of my ideas, even tools just for myself. It's also why local-first software is going to be massive - paired with AI code gen, anyone can build an app for themselves with no infra. Will be hot topic at @localfirstconf.com
