Been working on PgBeam, a PostgreSQL proxy that pools connections and caches queries across multiple regions.
Any driver, any ORM, just swap the connection string. Live benchmark running real queries from 20 regions: pgbeam.com/launch

We needed a storage layer that can scale to a huge number of volumes (think millions) for our Postgres platform.
Most of the existing storage systems are optimized for a few volumes with really high performance. But we needed the opposite: a very large number of mostly idle volumes.
So we wrote our own.
It’s called Xatastor and it enables Postgres-per-tenant use cases, “ephemeral” dbs for agents, free tiers, etc. Supports copy-on-write snapshots, clones, and thin provisioning.
It’s based on ZFS and NVMe-oF as key technologies. Link with all the details in the first reply.

The future of databases in the post-AI age. At @xata we believe in this vision and can't wait to share more on how Copy on Write unlocks agentic workflows with production-like data at minimal cost.
Meet the new Netlify Database.
Fully managed Postgres, built into the platform. Every agent run automatically gets its own database branch.
Here's why that matters. 🧵

Xata is now open source. Apache 2.0.
Postgres platform with Copy-on-write branching at the storage layer. Copy a TB-sized database in seconds. Inactive copies scale to zero automatically. 100% vanilla Postgres.
Two use cases driving this:
• Preview and testing environments with real production data
• Platforms provisioning per-user Postgres at scale
Built on CloudNativePG + OpenEBS. Runs on Kubernetes.
What's in the release:
• SQL gateway, responsible for routing, IP filtering, waking up scaled-to-zero clusters, serving the serverless driver over HTTP / websockets, etc.
• Branch operator managing all resources related to a branch.
• Clusters and projects services for the control-plane and REST APIs
• Auth service, based on Keycloack for API keys
• CLI that makes use of the REST API
• Scale-to-zero CNPG plugin for automatically hibernating branches on inactivity
This is the first of several announcements. More next week.
"Deploy globally" is a lie when your database is in us-east-1.
The next big infrastructure unlock isn't faster compute. It's making the data layer invisible.
Curious if @rauchg and @cramforce see this the same way.

Weekend idea shipped to upstream open source project in less than 24 hours, we're cooking!
Thanks @ctatedev for the awesome @vercel labs projects! This is just the beginning, let's see where we can take this 🫡
Weekend project: terminal renderer for @vercel json-render using ink.
Same JSON spec that drives web UIs now renders fully interactive terminal apps: text inputs, selects, markdown, tables, and more.
The spec patches in real-time as the model generates, so you can see components stream progressively instead of waiting for the full response from the LLM.

I don’t think AI is lowering the barrier to entry as much as it is giving the very smartest people an even more enormous advantage.
Has anyone successfully used @vercel @v0 with applications that use @better_auth?
With all environment variables set, origins+cors configured, when trying to sign-in server logs show 200 requests but the sandbox proxy returns a 500 to the browser...
Scope creep feels different with AI nowadays, it's cheaper to build the products that you've dreamed of with the quality you always wanted them to be!

don't call it vibe coding - that's associated with yolo i smash head on keyboard, not thinking, engineering, building, testing, debugging, iterating.
agentic engineering, or just...coding. We move faster, but it's still hard.
This is huge!
Vercel Sandboxes now support filesystem snapshots.
Capture complete state with 𝚜𝚊𝚗𝚍𝚋𝚘𝚡.𝚜𝚗𝚊𝚙𝚜𝚑𝚘𝚝() to skip repeatedly slow setup steps like git clone and dependency installation.

@Correos Os ha expirado el certificado de la API de modify.correos.es y no funciona, para que se lo digáis a un ingeniero y ya de paso que ponga unos tests E2E 🫠
@MatthewStanciu @pranavkarthik__ I wonder if vercel.ts opens the door for pre-deployment hooks. Have you thought of adding async primitives to it?
