We are at an epoch moment with AI, everything is changing, and the abstractions we build on are chaining to enable it.
Sync is that abstraction, and this conference is going to be one that is remembered as instrumental.

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 🧵

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. 🧵

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!

Interesting in building products on a local-first / sync engine architecture?

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.

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

🧵 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.

Here's my @localfirstconf.com talk introducing @tanstack.com DB, hexdocs.pm/phoenix_sync, syncconf.dev and arguing that Sync is the key to mainstream adoption of #local-first.

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.
