Big shift No browser WebContainer path anymore. The product is now built around server microVM execution, with per-chat sandbox sessions so follow-up runs can inspect files, patch code, rerun, test commands, and keep iterating in the same workspace.

6/ 成本对比：自建 sandbox vs 托管方案 自己搭 Firecracker microVM： - 运维成本：需要专人管理镜像更新、安全补丁、资源调度 - 启动延迟：30-60 秒冷启动 - 规模瓶颈：千级别 sandbox 就需要 dedicated 团队 用托管方案（Ona/E2B/Modal）： - 按 usage 付费，从几百到几千个 sandbox 线性扩展 - 启动延迟：秒级别 - 安全性：provider 负责隔离和审计 对大多数 builder 来说，托管方案是更优解。

AIエージェントを「使ってみた」段階から「不特定多数に解放する」段階に移すと、サンドボックス設計が事業の生命線になる。3〜5年後、エージェント運用の競争力はモデル選定ではなく隔離アーキテクチャで決まると見ている。 📌 ポイント - session単位でmicroVMを立てる構成が標準化し、テナント分離は「VM同等の境界」が最低ラインになる - Read/Write系はプロセス内で閉じるが、Bashを開けた瞬間に境界が崩れる。allow設計が運用品質を左右する - 建築・リフォーム業界の現場AIも同じ構図。図面・見積・顧客データを扱う以上、隔離設計を前提

finally got docker running in a microvm in a single command. our @microsandbox cli api is really coming nicely together. this example creates a microvm with 2gb memory limit, a mounted disk image to store docker containers and a script to start the docker daemon. once in the vm, you can run docker commands: docker run -it --rm ubuntu

Designed the architecture for Runix A microVM-powered sandbox platform that lets developers and AI agents spin up isolated runtime environments on demand. SDK → API → Scheduler → Host Agent → Firecracker Runtime → Sandbox Agent #rustlang #firecracker #microvm #opensource

というか，数百程度のサンドボックスだったら，今はローカルにある自分のDGX Sparkクラスタで，自分の作ったmicroVMフレームワークを使うよ．電気代だけだし．

How do you deploy AI agents for financial institutions without compromising on security, isolation, or scale? Rogo powers complex research, analysis, and deal workflows for leading financial firms, supporting complex tasks across tens of thousands of concurrent users. To meet the diverse needs of financial teams, Rogo relies on both specialist and general-purpose agents that can adapt to a wide range of workflows. With Claude Managed Agents and self-hosted sandboxes, Rogo gets the orchestration and post-training capabilities needed to design these agent systems, while E2B provides the execution layer underneath. Every piece of code generated by an agent runs inside its own E2B sandbox with full auditability and traceability. Each sandbox is powered by an isolated microVM, providing the kernel-level isolation critical for Rogo's customers. The result is a seamless agent experience backed by the security, reliability, and compliance requirements that financial institutions demand.

we do support firecracker microvm with docker daemon inside if you need to run docker compose integration test with Bazel (we have a few users with tons of those)

Learn how to deploy the Pi coding agent within a secure, isolated microVM using the Docker Sandbox (sbx) CLI. The process emphasizes security and privacy, specifically by utilizing a host-side proxy that allows the agent to use Anthropic API. youtu.be/P7AZ-iDbIoc?si=Pdwj…

What is a Linux bridge network? 🧐 Tech has been gradually moving from Docker containers to Kubernetes pods to microVM sandboxes, but bridge networks remain the dominant way to interconnect multiple "units of compute" running on a single host. Dive in: labs.iximiuz.com/tutorials/c…

The gains not just real - they are rather fascinating. This is the drop that happened when I moved the sshd in the microVM to VSOCK.

Docker's sbx allows to run AI coding agents inside a microVM with its own kernel, an outbound proxy, and credentials held on the host. That makes --dangerously-skip-permissions safer to use.

Frankly, Docker jumps through too many hoops. It hurts me to think every time about veth - and I spent quite some time figuring it out. The newer solutions have been cleaner. And I irrationally like microvm.

7/9 New entry: Cloudflare Sandboxes (GA April 2026, @Cloudflare). Fingerprint: "4/4/4/2/4/-/1" L1:4 Firecracker microVM per sandbox. L4:2/G:3 programmable egress proxy with default-deny opt-in (enableInternet=false). L5:4 Worker-proxy credential injection. Real secrets never enter the sandbox.

Yeah, sadly, firecracker is not a user solution. It's only reasonable for a compute provider. You can only be sold microVMs, you can't bring your own microVM solution. It's a sad, sad world, because I love virtualization and wish I could just use whatever virt technology I like
