Every major AI platform has now shipped managed agents. On the same sandbox-based architecture.

That architecture is wrong. Managed agents don't belong in sandboxes. They belong in functions 🧵👇

Introducing Electric Agents!

Agents are not compute. Agents are data. Multi-agent is a sync problem. Electric Agents is the first agent platform built on sync.

Use it to build scalable, collaborative, long-lived multi-agent systems: 🧵👇

🚀@Tan_Stack DB taking off.

That's 100k growth in a week.

Can Doom run on @DurableStreams? Absolutely!

The result: live streaming, rewinding, and forking — branch from any point and you're instantly back in the game!

[Electric @ElectricSQL]

Agent sessions shouldn’t be linear.
To rewind, explore alternatives, and fan out in parallel, they need a data primitive with branching.
Fork is now live for Durable Streams: branch any stream at any point with a single API call.

Yjs is the #1 library for collaborative editing on the web. Today we're announcing built-in Yjs support for @DurableStreams. Use it to add multi-user and multi-agent collaboration to your AI apps and agentic systems.

Reads are free. Unlimited. Forever.
Electric Cloud pricing is live — pay only for writes & retention.
Two primitives: Durable Streams (AI, multi-agent, real-time) and Postgres Sync (the magic behind fast apps).

StreamDB - a reactive database in a Durable Stream. Designed for AI apps and agentic session state.

You give it a Standard Schema. You get type-safe, multiplexed data sync into @tan_stack DB.

@samwillis and I have been cooking on this for a while. You can now write hierarchical queries to sync relational data and persist collections to SQLite. This unlocks local-first apps when combined with @tanstack/offline-transactions 🤓🔥

[Sam Willis @samwillis]

Two key things I've wanted to add to @tan_stack DB since the beginning are now here:
🌴 Hierarchical live queries that project to the shape of your UI, no more n+1. GraphQL without the infra.
💾 Persistence *on all platforms* via sqlite.
Go try it!🚀🥳

[Kevin De Porre @KevinDP55]

Been waiting for PostGIS support in PGlite for quite a while, very happy to see it become a reality. This unlocks so many apps! 🐘

[Electric @ElectricSQL]

PGlite v0.4 is out 🚀
PostGIS, connection multiplexing, and a major architecture refactor - bringing embedded Postgres closer to native.
Now at 13M+ weekly downloads and showing up everywhere from CI to browser-based dev environments.

Announcing Durable Transports for your AI SDK!

Multi-user, multi-agent collaboration for your @tan_stack AI and @aisdk apps.

Built on @DurableStreams. With turnkey hosting on @ElectricSQL Cloud. Links in the 🧵

[Sam Willis @samwillis]

So awesome - @prisma Studio is now built on @tan_stack DB 🔥

[Electric @ElectricSQL]

We've shipped Agent SKILLs for the Electric & Durable Streams clients & TanStack DB!

The vibe coding experience is night and day better — you can now one-shot complex apps w/o any errors!

[Local-First Conf @localfirstconf]

Local-First Conf 2026 tickets are now on sale.

July 12–14 · Berlin · 350 people · single track

This year's theme: user empowerment in an age of fluid software. We're going beyond CRDTs to explore malleable software, peer-to-peer, self-sovereign identity, open-weight models, ATproto, and much more.

If you're building for user agency, this is your conference. CFP is open. We want YOUR talk. 👇https://t.co/Lwu3LVMznj

1/ A law from computer science — published in 1967 — explains why some teams get 10x from AI agents and others plateau at 2x. It has nothing to do with Codex vs. Claude.

[Kevin De Porre @KevinDP55]

@DominikTornow How do you know your slop is correct in the first place? Formally verifying slop may well be harder than formally verifying a well written implementation.

[Electric @ElectricSQL]

1/Hosted durable streams is live on Electric Cloud!

Persistent, resumable event streams over HTTP. Reads served from CDN, tested to 1M concurrent connections. 240K writes/second. 5M writes/month free.

[Sam Willis @samwillis]

You can build difficult things with LLMs now!
In 2022, I described a "real-time collaborative parametric CAD app" on Hacker News, thinking it was out of reach
I just built one over the holidays!
I've written up my experience, part 1 out now - link in 🧵

Introducing Durable Sessions — the key pattern for collaborative AI.

As the world moves to getting things done through agents, the winners are going to be the products that combine AI with collaboration. Building AI apps on a Durable Session pattern is the best way to do that.

The post linked in the 🧵below shows how you can build Durable Sessions into your existing stack, schema and AI SDK using Durable Streams from @ElectricSQL and @TanStack DB.
