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.

It's super easy to take your existing SQL queries in Next.js and make them update *live* with @neondatabase Realtime!
It's only a few new lines of code 🤯

Shipping so fast! Love the excitement around it 🥳
Reactive live queries straight from Postgres to your mobile app!
The @neondatabase Realtime client now supports React Native and @expo 🎉🚀

@neondatabase Realtime v0.1.2 now supports React Native! 🎉
One todo app, running on native and web. Make a change in either and watch it sync to the other 👇

There is a bunch of "TypeScript compiled to native" projects about, but this is the OG and the one to watch!
Oh, and it's not just TypeScript, it's all of JavaScript!

This is such an awsome overview of @neondatabase Realtime, and how you can build advanced multi-user/agent systems on it with @mastra.
Perfect pairing! 🚀🥳

Want your UI to automatically update when your data changes? Just write to Postgres.
Neon Realtime composes beautifully with Mastra 🫶

Any SQL query, reactively kept up to date on front end.
And is so so simple to use, even and agent can do it!

Six years ago I was building an app, and thought "wouldn't it be so much easer if we could just subscribe to a query on the front end".
That started my journey through Local First, lead to joining @ElectricSQL, where we built multiple Sync Engines, PGlite and @tan_stack DB.
We finally achieved that goal with @neondatabase Realtime.
Perfect thing for a side project, give it a go!

Playing around with Neon Realtime + @tan_stack DB. Even the background is synced 🌴😎

With @neondatabase Realtime you can take almost any sql query and make it reactive on the front end.
And it only takes a few lines of code!
Any change in Postgres is immediately reflected on the front end.
I’m so very excited that Neon Realtime is out! 🚀🎉
Live reactive SQL queries, straight from Postgres
Subscribe to ANY query from the front end, and it will been updated in realtime.
To do this we built a brand new sync/query engine, running inside Postgres.
For anyone who’s worked on a sync engine, being inside Postgres is a bit like being in a sweet shop, it’s all we ever wanted! Everything we could possible need is just there and ready to use.
We’re going to be writing more about how we built it in the coming weeks, but want to say I’m indelibly proud of what the team have achieved, it’s very VERY cool.
I’m looking forward to seeing how our users get on with it!
If you have any questions, give me a shout!

Neon realtime engine runs in a shallow read replica. Only lakebase architecture has severless read replicas that can run such an engine
Let's get one thing straight, the Tesla Roadster isn't a flying car.
It's a jumping car.
And it's awsome!
I have extreme admiration for the team working on it. What an incredible job for those luckily bunch!
