# Rivet Blog

Rivet's engineering blog at [rivet.dev/blog](https://rivet.dev/blog). The team builds the [[toolbox/sandbox-agent-sdk]] — an open-source orchestrator for running AI coding agents inside microVMs. The blog writes from the same vantage: how the substrate (Docker Sandboxes, Firecracker, Cloud Hypervisor) actually works, with code listings and curl invocations rather than overviews.

The reverse-engineering writeup is the canonical post — the kind of thing that's useful exactly because Docker hasn't documented the API yet.

- [[rivet-docker-sandbox-microvm]] (2026-02-04) — Reverse-engineering Docker's undocumented `/vm` HTTP API; the post that pinned down the API surface for [[microvm-2026]]'s Docker Sandbox entry.

Rivet's earlier work (pre-Sandbox SDK pivot) was a multiplayer game backend. The blog name "Rivet" predates the sandbox focus.
