s2.dev

added some really nice real-time metrics to our dashboard, thanks to @s2_streamstore previously, we kept everything in elasticsearch which was also a lot harder to setup for new data streams the stream is such a nice DX primitive - instead of adding elastic indices/queries for every part of our backend, we just emit streams instead it's so elegant

"So we decided to also write every event to a durable log (a service called S2) as it happens. The browser disappears, but its timeline doesn't."

@xmlking @mwylde @CloudflareDev @ArroyoSystems thanks for the shoutout @mwylde! @xmlking an OSS version of S2 called s2-lite is also available, github.com/s2-streamstore…

@mwylde @CloudflareDev @ArroyoSystems @s2_streamstore Thanks for sharing. Globally addressable , repayable, resumable sounds interesting. Hope it low TCO like S3

The @CloudflareDev Data Platform is going GA next month, seems like a good time to mention that I'm hiring across the Data Platform teams. If you've built databases/streaming engines/query engines/other high-scale data infra, I'd love to chat!

we just released opbox.dev, which is a fun way to add real-time sync to regular ol' textfiles on disk youtube.com/watch?v=ewhPus…

Seems like Local AI is getting more and more relevant, so I wrote about it! s2.dev/blog/local-ai

If you have wondered whether to use the s2.dev cloud service, or self-host s2-lite (github.com/s2-streamstore…) – #cloud-service-comparison" target="_blank" rel="nofollow noopener">s2.dev/docs/s2-lite#c…

every day the @runpentagon desktop experience gets faster and more reliable shoutout @s2_streamstore for helping our multiplayer agent-to-agent communication cook

turns out "one stream per session" is not just for agents. it works for browser sessions too. built RePlaya, a self-hosted session replay tool where each visit is just an @s2_streamstore stream you can play back or tail live. recording = append playback = read live replay = tail

Streams as a cloud storage primitive, now in more places. S2 is the serverless API for unlimited, durable, real-time streams. Today, we're adding US West and EU North as new basin locations. s2.dev/blog/locations…

@tonboio good to know of the catch-up breakage, we'll investigate and fix! s2-lite is much younger than the cloud service, it's the same API but different backends

Hey @s2_streamstore, when's the multi-node version of open-source S2 shipping? Asking for a friend who wants quorum durability + self-hosting. (Ursula benchmarks 18× vs S2 Lite, but single-process isn't a fair fight. Would love a real one. 😉)

Just open-sourced Ursula: an HTTP event streams server. Built on @ElectricSQL's Durable Streams Protocol, Ursula keeps a combo we have not seen elsewhere: { Apache 2.0, quorum-replicated, sub-50ms p99, S3 economics }. github.com/tonbo-io/ursula

@tonboio congrats on launching. multi-node s2-lite is not on the current roadmap :) for elastic scalability we recommend the managed service s2.dev

You can plug @s2_streamstore into your anthropic sdk based chat app and make your chats durable!

Streaming shouldn’t break when connections do. Meet Durable Global Streams, like Kafka and S3 combined into severless storage for streams: @s2_streamstore → Replayable → Resumable → Globally available, backed by Tigris storage Built for real-time apps, AI agents, and anything that can’t afford to lose data. Back S2 with Tigris 👇

oh and tanstack ai too!

S2 now supports client-supplied encryption keys for durable streams. Bring your own per-request key, keep key material out of S2 storage and logs, and let S2 handle request-time encryption behind the stream API.

Claude makes for a great curl console. No MCP needed 😅 Here's a prompt to get you started with @s2_streamstore (sign up and get an access token first, see env var reference) ``` Refer to s2.dev/docs/llms.txt and use S2_ACCESS_TOKEN env as bearer token. Create a basin called something unique with stream auto-creation enabled on read or append, and delete empty streams after 1h. Start an SSE read and append a "hello world" record, let me know if it comes through. ```

@garrytan put a @runpentagon gstack team on this - here's a skill to set up private group chats for agents built on top of @s2_streamstore: shoutout @sgbalogh0 for a great coffee chat the other day that put s2 top of mind github.com/arlington-labs…
