Release Notes 2026.10.0

Since our last release notes we've shipped an AI app builder, a link shortener, private tunnels to your other clouds, monitoring and automatic restart for your servers, application logging, and a chat that can draw, write files, and keep working after you close the tab.

App Builder: describe it, and an AI agent builds it

App Builder turns a plain description into a working website. You tell an agent what you want, it writes a plan, and you watch it check off each step as it creates the files.

• Upload brand notes, copy, or specs, and the agent works from them.
• Preview the result right in the dashboard at desktop, tablet, and phone widths. The preview is sealed off from the network and from your account, so nothing the code does can reach either.
• Put several agents on the job at once, each on the model you pick, and let an agent bring in helpers for bigger pieces of the work. You see what every agent spends while it works.
• Edit the code yourself in the built-in editor, with syntax colors, files, and folders. Create, rename, and delete anything.
• Every change, the agent's or yours, lands in a history with a diff per file, and any of it can be undone.
• Download the whole app as a zip whenever you like.

Each step an agent takes is billed as AI usage at the model's token rate. App Builder writes the site and stops there: it doesn't run server code or publish anything for you. Download the files and put them on a Spark server or any host you like.

Link Shortener

Short links now live on Carpathian. Shorten any URL on cpthn.ai, or put your links on your own domain once you verify you own it with a DNS record, and track how many times each link gets clicked.

• Any public file in Object Storage gets a Copy short URL action.
• One flat monthly price for the service, with each custom domain added on top. Links on cpthn.ai cost nothing extra.

Private Link: connect your other cloud

Private Link joins a Carpathian VLAN to a network you run somewhere else, like a VPC in another cloud, over an encrypted WireGuard tunnel. Servers on both sides reach each other by private address, and neither side becomes reachable from the internet. Your side needs a public address for the tunnel to dial; ours doesn't listen for anything.

Spark Servers

• Each server now shows its CPU, memory, network, and disk history over the last hour, day, or week, along with its uptime.
• If a server stops due to errors, you get a notice. Turn on automatic restart and it comes back on its own.
