This one found us on its own. Sundaram built an AI coding assistant in Node.js and TypeScript with the Anthropic SDK: it writes, runs, and exports code in Python, JS, TS, and Bash inside a Tensorlake sandbox, with a web UI that streams the agent's thoughts and tool output as it works. The demo is 53 seconds; the code is public if you want to see how the agent loop is wired.

We didn’t write this one — it’s Sundaram Kumar Jha’s piece, published on X. The note above is ours; the full article is theirs.

Tensorlake Sandboxes as the runtime for Claude Managed Agents.Run Claude Managed Agents on Tensorlake Sandboxes: you keep the control of self-hosting, and drop the always-on box. The short version — the server goes away.

Firecracker disk snapshots in O(changed bytes), not O(disk size)We added copy-on-write image layering inside Firecracker's block device, and the disk got faster, not slower. Snapshots pause the VM for tens of milliseconds and cost only what changed, so a running Postgres barely notices them, at any disk size.
