Vercel Sandbox is now generally available — isolated Linux microVMs for AI agents via Firecracker with active-CPU pricing. Already powering BlackboxAI, Roocode, and v0. Supports clone/fork/resume via snapshotting. Direct competitor to E2B and Modal for the agent runtime layer.

Docker's formal entry into agent infrastructure isn't just another tool launch — it's a platform-level event that could reshape how agents are packaged and deployed. Docker Engineering released docker-agent, an official AI Agent Builder and Runtime written in Go, reaching 2,46...
In roughly eight weeks: omnigent-ai/omnigent (8,418 stars), vercel/eve (4,492), clawkwork/clawk (951, "give coding agents a disposable Linux VM, not your laptop"), tastyeffectco/sandboxd (885), BitMiracle-AI/Dormice (557, pitching "the SQLite of agent sandboxes," self-hosted,...
kvcache-ai/AgentENV shipped MIT-licensed on July 27. Each agent environment is a Firecracker microVM with its own Linux kernel, filesystem, and network namespace rather than a container, with overlaybd layered images sharing read-only base layers. Reported: sub-50ms boot/resum...
Firecracker + CoW mmap forking spawns KVM-isolated sandboxes in 0.79ms p50 with 265KB memory per instance — versus E2B's ~150ms and ~128MB. At this scale, sandboxed code execution becomes viable inside interactive agent loops where latency directly impacts UX. GitHub ---
Rohan Adwankar disassembled two hosted agent sandboxes. Claude Code runs Firecracker KVM guests on kernel 6.18.5-fc-v20 with a Rust/Tokio process_api binary as PID 1 instead of systemd, reaching init in about 430ms and full harness readiness in 6.4 seconds, with a 256GB writab...
Each project gets a throwaway VM where the agent has full tool access to Docker, git, compilers and package managers with no path back to the host (GitHub). coop setup installs Firecracker and a guest kernel on Linux; macOS goes through Lima via Homebrew. Usage is coop up then...
