oh and tanstack ai too!

Make your aisdk chat app crash proof by using s2.dev as the persistence layer behind useChat!

Sorry folks, if you are going to video conference over a database, it better be a Stream Store. s2.dev/blog/video-c...

There's two new ways to manage S2 as code! The Terraform provider lets you manage resources with full lifecycle support. Available on the Terraform Registry at s2-streamstore/s2. Or you can use the CLI by `s2 apply` which takes a declarative JSON spec and creates/reconfigures specified resources.

The s2.dev dashboard now has a Data Plane studio to make it convenient to work with streams. You can: -Do one-shot reads, live tail from any stream, start from an offset, seq no., or timestamp -Append records in multiple modes -Run stream commands -Inspect records with command record aware rendering

The S2 cloud service is now GA! We also raised a $3.85M seed round led by Accel with participation from Y Combinator, and other funds and angels like @t3.gg @chris.blue @fulmicoton.bsky.social s2.dev/blog/ga

It was fun to run multi-agent research cohorts and have them connect over durable streams, making infinitely many reasoning topologies possible!

Curious about the architecture of S2? This is how we cook infinite durable streams for you.

just got finished no-lifing on building a TUI for s2, wdyt?

s2-lite is here – an open source @s2.dev Stream Store! It's a single binary you can run anywhere. Powered by SlateDB, so you can point it at an object storage bucket for durable streams with real-time reads. github.com/s2-streamsto...

Thankful to the @s2.dev team for all the progress we made this year! Really excited for 2026. Some highlights 🧵

had a fun time chasing an issue that adding RUST_BACKTRACE=full just OOMKilled one of our pods

just tried out the real-time TodoMVC example with @livestore.dev + @s2.dev as the durable sync provider, and honestly its crazy how fast it is! local SQLite, works offline, real-time updates and no complex setup, just works

Excited to share y-s2, an open-source serverless backend for real-time collaborative applications using Yjs and @s2.dev!

After a bout of hallucination, I had GPT5 generate some backronyms for itself: - Generally Pretends Truthfully - Gullible People’s Trick - Greatly Pretends Things - Generated, Probably Twisted - Guessing, Passing, Tricking - Good at Pretending Truths - Generally Produces Tall-tales

I wrote a bit about how we verify linearizability of @s2.dev using Porcupine! s2.dev/blog/lineari...

s2.dev got a refresh ✨

Our Star Wars quickstart got good feedback, and now you can view the stream from the dashboard too 🫣 This comes in real handy for live debugging and observability — especially in systems built around agentic workflows, microservices, or event sourcing using @s2.dev

@s2.dev can now automatically delete streams where all records have fallen out of retention or it was never written to, based on a configurable time threshold. The option is called "delete-on-empty" and you can set it up on the default stream configuration for your basin from the dashboard or CLI!

Agents need granular streams. And yes, @s2.dev fits the bill nicely! s2.dev/blog/agent-s...

Super cool XTDB plugin from @chuck.cassel.dev, which implements the write-ahead log using @s2.dev streams: github.com/chucklehead-...

Change data capture from Postgres is simple with the right tools. We collaborated with sequinstream.com on an integration so you can use @s2.dev to ship real-time features faster!

Had a lot of fun with this 😄 – a multiplayer, "instant re-playable" pseudoterminal that uses @s2.dev streams as a transport instead of SSH: s2.dev/blog/s2-term

You can now safely share @s2.dev streams directly with end clients like browsers, apps, or agents! No proxying required. Check it out, s2.dev/blog/access-...

Kind words from Chris about S2! I felt strongly that we needed to not hitch our wagon to Kafka. It is not even a priority for us, for now. This may seem like a strange analogy... but if Kafka is OLAP, we want to be OLTP. See this demo to understand what I mean: s2.dev/docs/integra...

We were inspired by Vercel's take on resumable streams in the Chat SDK, and thought — what if we took it a step further with S2? With the @s2-dev/resumable-stream npm package, you can use S2 as the backend for stream resumption in AI chat applications.

S2 is starting to do some really interesting stuff…

S2 now supports timestamps! 🕰️ How we made streams understand time: s2.dev/blog/timesta...

Adding a familiar tail command to the @s2.dev CLI felt natural! Some folks have compared Stream Store to a "serverless named pipe." It's an intuitive analogy, and here are some ways S2 is so much more: - Record-oriented - Durable on object storage - Built-in concurrency control

Create streams on the fly with ease. Just turn on this setting for your basin. @s2.dev

I blogged about our DST journey with @s2.dev s2.dev/blog/dst

The S2 CLI makes it super easy to manage basins and streams - but now you can also do a lot from within the dashboard! @s2.dev

just added an Accessibility page talking about what Wizard Zines has been doing to make things more accessible for screen reader users wizardzines.com/accessibility/

Just watched @sbalogh.bsky.social HYTRADBOI talk and I love the idea behind @s2.dev: using a stream as your database ✨ The simplicity of the API/concepts is going to make it accessible to teams who'd otherwise have to reach for ~kafka to get a similar architecture www.hytradboi.com/2025/f2cc03c...

Bytewax connector for @s2.dev is out now! bytewax.io/blog/s2-conn...

I have a talk about S2 at HYTRADBOI this friday! www.hytradboi.com/2025/

Talk 24: "Serverless primitives for the shared log architecture" by Stephen Balogh (@sbalogh.bsky.social)

S2 now has an official Java SDK! github.com/s2-streamsto...

Is Kafka a log? No Is a Kafka topic a log? No, the topic-partition is the log. A Kinesis stream is not a log either. The stream-shard is. S2 does not bury the core abstraction everyone can get behind. An S2 stream is a log.

📣 Today on the blog, check out this awesome case study with @s2.dev sharing some of their successes with Polar Signals Cloud (spoiler, they're huge!) 🧊 www.polarsignals.com/blog/posts/2...

On a more personal level, we are honoured that we got to work with @schmizz.net and the rest of the @s2.dev team ahead of their launch and managed to play a small role in their really awesome product!

I absolutely love seeing our customers use our product to make theirs better! Check out our block to learn how @s2.dev did just that

Really excited to announce @s2.dev components for Bento 🎉 You can now integrate S2 streams as inputs and outputs in your pipelines. Get started: s2.dev/docs/integra...

You can easily power your next IoT project's data streaming pipeline with S2, and I wrote a blogpost showing exactly how you can do it! s2.dev/blog/iot

Love how @s2.dev guides you through reproducing ASCII Star Wars in your terminal. It's a fun, clear and engaging quickstart example. Well played.

Hey Gophers! Got some great news for you. @s2.dev now has an official SDK for Go 🎉 Checkout the repo at github.com/s2-streamsto...

If you are using AWS S3 SDK for Rust on Graviton, you should enable the 'asm' feature on the sha2 lib transitive dep explicitly. Otherwise, it will not end up using hardware acceleration. Huge CPU drop for one of our services. Identified this issue using @polarsignals.com

Wrote a post exploring how replicated databases can be built on top of an @s2.dev stream by using it as a write-ahead log (also shows off the official S2 rust sdk!) s2.dev/blog/kv-store

This looks very cool: S2: Streams as a cloud storage primitive
