anything | tsf Launching tail.surf: live gists for terminals, apps, and agents. Pipe any output into tsf and get a stable URL. Follow live, scrub back in time, or replay the full history.
You can now use S2 as a backend for Mastra Durable Agents! The @ s2-dev/mastra-pubsub adapter maps each durable topic to an S2 stream, with live delivery, replay after refreshes or process restarts, and distributed leases for coordinating thread ownership across processes.
shikhar@schmizz.net · last mo.What if your brain could be a pet? @anthropic.com have shared the benefits of decoupling the brain from its hands. We have also written about using a stream per agent session as a WAL and what that unlocks. If it seems complicated, it is. And durable execution frameworks are far too intrusive.
S2 source and sink plugins are now available for Streamling. Read durable S2 streams into Arrow batches, or write Streamling output back to S2. ClickHouse ingestion, Postgres CDC, and a full Postgres → S2 → ClickHouse example: s2.dev/docs/integr...
we just released opbox.dev, which is a fun way to bring real-time sync to directories of plain textfiles (markdown, code, what have you..) on disk youtube.com/watch?v=ewhP...
opbox
opbox is an experimental open-source daemon that syncs directories of plain text files between machines in real time — CRDT merges, any editor, end-to-end encrypted, offline-friendly.

turns out "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.dev stream you can play back or tail live. recording = append playback = read live replay = tail github.com/s2-streamsto...
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/locatio...
Two new locations for your streams: US West and EU North
S2 introduces location as a first-class construct, with two new ones to choose from: western US and northern Europe.

@s2.dev 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. s2.dev/blog/encrypt...
Your data, your keys
S2 now supports client-supplied encryption keys for durable streams, giving teams control over key material without changing record APIs.

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
General availability & our seed round
S2 is now GA. Plus, $3.85M in seed funding led by Accel.

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 🧵
S2 is now SOC 2 Type II compliant! We are committed to continuously improving our security posture.
We are at SyncConf SF! Find us or DM if you wanna chat streams (or logs if you prefer!)
👀 "This is the home of s2-lite — an open source, self-hostable implementation of the S2 API for durable streams. It will be backed by SlateDB, and it is currently in development."

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
