Era – Open-source local sandbox for AI agents

In plain words

Era is an open-source sandbox tool that isolates AI-generated code using microVM-based technology and hardware-level security. It is designed for developers running AI agents locally who need protection against malicious code execution. Era provides isolation stronger than traditional containers, preventing compromised AI agents from affecting the host system.

From the sources

Open source local sandboxing for running AI generated code. - BinSquare/ERA

Run untrusted or AI-generated code locally with the security guarantees of microVM and ease of use from containers. There's a managed cloud layer through cloudflare, globally deployed Worker/API, jump to cloudflare/README.md . This project is early stage, experimental. We will be changing and breaking things temporarily as we port towards rust. Expect bugs, please report them. # 1. install the tap brew tap binsquare/era-agent-cli brew tap slp/krun # 2. install era agent brew install binsquare/era-agent-cli/era-agent # 3. install dependencies brew install krunvm buildah # 4. verify the CLI is on PATH agent vm exec --help # 4. follow platform-specific setup (see below) option 2: from source #…from github.com

In the maker’s words, at launch

Just watched this video by ThePrimeagen (https://www.youtube.com/watch?v=efwDZw7l2Nk) about attackers jailbreaking Claude to run cyber attacks. The core issue: AI agents need isolation. We built ERA to fix this – local microVM-based sandboxing for AI-generated code with hardware-level security. Think…

  AI changed the way we code, but we're still using the old processes, and we've become the bottleneck, the AI is waiting for us - to reply, to open our laptops, to review the code, and so on. We're building the future of AI software development. The agents are autonomous, they run in sandboxes, automatically fix the pipelines, and deliver you the final, working code. You can use live preview to see the changes they made. Working across multiple repositories, all within the same session. This is the future - you don't need an IDE, and you don't have to run anything locally.

  hi guys. been working on something i think is fundamentally missing in today's workflow with ai agents. vcs. i find myself struggling with questions that agents can't answer like "why did you do it?", "when did u delete this folder? why?", etc. or trying to /rewind (after a /compact...) or basically `bisect` to find when and why something was done by the agent in the current / previous session. just like git did for code, i think we are the same core capabilities with ai agents so... i developed an open source solution for that (currently supporting claude code) would love to…

  Agent-of-empires: OpenCode and Claude Code session managerJan 2026 · github.com · ▲118

  Hi! I’m Nathan: an ML Engineer at Mozilla.ai: I built agent-of-empires (aoe): a CLI application to help you manage all of your running Claude Code/Opencode sessions and know when they are waiting for you. - Written in rust and relies on tmux for security and reliability - Monitors state of cli sessions to tell you when an agent is running vs idle vs waiting for your input - Manage sessions by naming them, grouping them, configuring profiles for various settings I'm passionate about getting self-hosted open-weight LLMs to be valid options to compete with proprietary closed models. One…

  Sandbox AI-app lifecycle, from build to runJun 2026 · capakit.com · ▲6

  Hi HN, This is a project I've been working on since the beginning of 2025 full time, without funding. Coding agents have fundamentally changed the way we write software. When you let an agent write code, pull dependencies, and run scripts, you are delegating trust while still keeping the responsibility. You shouldn't have to choose between moving fast with agents and maintaining basic control over your host machine. Normally, we just inspect the final result, treating the app like a black box. Most security tools only sandbox the app runtime and ignore the build phase. CapaKit is my attempt…
