Give every agent in Herdr its own Vercel Sandbox
↗
A new Herdr plugin lets terminal coding agents run in isolated Vercel Sandboxes, keeping all agent activity off the local machine while returning changes as reviewable Git patches.
Running multiple AI coding agents simultaneously no longer risks local filesystem corruption or resource contention, since each agent operates in its own sandboxed environment. The JSON-based interface and Git patch workflow make it feasible to orchestrate agents programmatically while maintaining human control over what gets applied.

Each agent runs inside an isolated Vercel Sandbox rather than on the local machine, with changes returned as Git patches the user chooses to apply.
All plugin actions return JSON, enabling scripts or other agents to start, inspect, and apply changes from sandboxed agents programmatically.
Verified agents include Claude Code (2.1.220), Codex (0.146.0), and OpenCode (1.18.9), with usage billed at standard Sandbox rates.
