1. E2B
Open-source, secure environment with real-world tools for enterprise-grade agents.
What sets it apart: Purpose-built sandboxed execution for AI-generated code with sub-second startup — vs generic containers which require more setup and have slower cold starts
Best for: Running untrusted AI-generated code safely; Building code execution features into AI applications
2. OpenSandbox
Secure, Fast, and Extensible Sandbox runtime for AI agents.
What sets it apart: Provides high-performance Firecracker-based sandboxes with pause/resume capabilities and unified API for both local Docker and Kubernetes deployments.
Best for: Running coding agents in isolated environments; Deploying browser-based AI agents securely; Scaling agent execution on Kubernetes infrastructure
3. Daytona
Daytona is a Secure and Elastic Infrastructure for Running AI-Generated Code
What sets it apart: Provides full composable computers with complete isolation that spin up in under 90ms for AI agent workflows.
Best for: running AI-generated code securely; building agent workflows; maintaining persistent agent environments
4. e2b
Python & JS/TS SDK for running AI-generated code/code interpreting in your AI app
What sets it apart: Purpose-built cloud infrastructure for AI-generated code execution — secure sandboxes designed specifically for LLM output, not repurposed containers
Best for: AI apps needing safe code execution from LLM outputs; Building AI coding assistants with runnable code; Data analysis agents that generate and run Python
5. Steel
🔥 Open Source Browser API for AI Agents & Apps. Steel Browser is a batteries-included browser sandbox that lets you automate the web without worrying about infrastructure.
What sets it apart: Purpose-built browser infrastructure for AI agents — combines session management, stealth, proxy rotation, and Puppeteer/Playwright compatibility in one API
Best for: AI agents needing real web browsing capabilities; Web scraping with anti-detection requirements; Browser automation tools needing managed sessions
6. BrowserOS
🌐 The open-source Agentic browser; alternative to ChatGPT Atlas, Perplexity Comet, Dia.
What sets it apart: Agents work with real user logins in a dedicated browser environment rather than headless sandboxes.
Best for: Automating logged-in web tasks (social media, email, CRM); Running multiple agents simultaneously; Privacy-focused local agent execution
7. herdr
the runtime your coding agents live on
What sets it apart: Provides a persistent runtime environment specifically optimized for coding agents that can survive client disconnections and machine restarts.
Best for: Developers building coding agents; Teams running multiple AI coding assistants; Managing persistent agent sessions across machines
8. teable
✨ AI Spreadsheet for Business
What sets it apart: Combines a full PostgreSQL database platform with isolated AI agent sandboxes and no-code app building in one self-hostable environment.
Best for: Business teams building internal AI tools; Creating data-driven AI workflows; Deploying AI agents in controlled environments
