Runtime
Run sandboxed AI coding agents safely across your entire team.
Quick answer
Runtime — Run sandboxed AI coding agents safely across your entire team. It's freemium. Best for running AI-generated scripts in a safe, isolated environment before deploying to production.
Runtime is an AI-powered developer platform that provides sandboxed coding agents designed to help every member of a software team write, run, and iterate on code safely and efficiently. Rather than exposing production environments to unpredictable AI-generated code, Runtime wraps each coding agent in an isolated sandbox, so experiments, scripts, and automated tasks stay contained and risk-free. The platform is built for engineering teams of all sizes, from solo developers who want a safe scratchpad for AI-assisted coding to larger organizations that need collaborative, controlled environments where multiple team members can work with AI agents simultaneously. What makes Runtime particularly compelling is its focus on accessibility: you do not need to be a senior engineer to benefit from its capabilities, since the sandboxed approach removes the fear of breaking things while still delivering powerful code execution. Runtime bridges the gap between raw AI coding power and practical, everyday team use by combining automation, safety, and ease of use in a single developer-focused workspace.
Key features
- Isolated sandboxed environments for AI coding agents
- Team-wide access so every member can run coding agents
- Safe code execution without risk to production systems
- Collaborative workspace for running and iterating on AI-generated code
Pros & cons
- +Sandboxed environments make AI-assisted coding safe for the entire team
- +Accessible design lowers the barrier for non-engineers to use coding agents
- +Reduces risk of accidental damage to production code or infrastructure
- −Relatively new platform so documentation and community resources may be limited
- −Sandbox limitations could restrict more advanced or resource-intensive coding tasks

Frequently asked questions
Is Runtime free?
Runtime offers a free tier that gives users access to sandboxed coding agents with limited usage. For teams that need more capacity or additional features, paid plans are available.
What is Runtime best used for?
Runtime is best used for running AI coding agents in safe, sandboxed environments. It is ideal for teams that want to automate development tasks, experiment with AI-generated code, or give non-engineers access to coding tools without risking production systems.
What are the best alternatives to Runtime?
Alternatives to Runtime include E2B (which also provides sandboxed code execution for AI agents), Replit (a collaborative browser-based coding environment), GitHub Codespaces (cloud-hosted dev environments), and Daytona (secure development environment management).
Is Runtime safe to use?
Yes, safety is a core design principle of Runtime. Every coding agent runs inside an isolated sandbox, which means AI-generated code cannot affect your production systems or other team members' environments. This containment makes it significantly safer than running AI agents directly on local or production infrastructure.
How much does Runtime cost?
Runtime has a free tier available for individuals or small teams getting started. Paid plans are estimated to start around $20 per month, with enterprise pricing available for larger organizations that require custom capacity or dedicated support.
