Building Agents & composable sync primitives @ElectricSQL.
Sync Engines, Durable Streams & AI.
Started co-creator of @tan_stack DB.

My overriding thought going into 2026:
Problems you thought were out of reach no longer are.
Pick a problem 100x harder than you thought possible to tackle alone, and run with it.
Start now. AI will catch up and make it possible.

A company just rolled out TanStack DB with offline transactions to 660k users of their mobile app!

[Sam Willis @samwillis]

"Most people see empty UI as a bug and immediately reach for a spinner. I see it as feedback."
"If part of the page pops in after navigation, that's the app telling me I forgot to preload something."
Love this framing!
A spinner is an anti-pattern, preloading (sync) is the fix.

🔖 we’ve spent years building better loading states, is it time to take a step back?

More convergences on the same ideas behind Electric Agents

"Session: Durable identity. Append-only event log"
"Make the agent multiplayer by construction"

[James Arthur @thruflo]

This.

Proud to be supporting superset on Electric Cloud!

[Kiet @FlyaKiet]

Introducing: Our users @superset_sh

[Kyle Mathews @kylemathews]

A big customer just finished a 100% rollout on Electric Cloud. Never an easy task!

[Sam Willis @samwillis]

@BenjDicken This chap has already done it!

Passes 96% of the test suite.

If you want to run 100k concurrent agents... you're not going to want run them in sandboxes.

(hint, check out Electric Agents)

[Sam Willis @samwillis]

Two new little features dropped in @tan_stack DB yesterday:
- unionAll() for constructing a live query that is a union of other queries or collections.
- caseWhen() for building queries that have conditions in them.
Both enable a bunch of exciting things 🎉🚀

i think this stack has won the localfirst battle btw. maybe more chapters to this story but i think this is it if you are building fast apps fast

Agent context needs stored somewhere hence logs and databases

Online agents that react to systems and each other need reactive contect hence sync

[James Arthur @thruflo]

Reactive context.

PGlite just passed 8 million downloads per week.

A database == query engine + page manager + write ahead log.
AI runtimes have a lot to lean from what's been built before.
When you introduce a durable, observable, serverless, write ahead log to your agents, you get distributed coordination.
Electric Agents gives you this!

Agent Runtime == model + harness + durable streams

In the next version of Electric Agents:

You can directly run agents from the CLI or from a TS API

electric agents run <type> [id] [message]

e.g. in CI when a new issue is created — `electric agents run horton "triage this issue"`

[Kyle Mathews @kylemathews]

It's a lot easier to build a coding harness then people think. 2 days in I'd say we're at ~60% of Claude Code / Codex / Open Code.

Models do most of the work. And @DurableStreams and TanStack DB make quick work of building an amazing app around the coding agent.
