Daytona Alternative: A Persistent, Always-On Sandbox for Your AI Coding Agent
Daytona grew up as infrastructure for developer environments and now leans into running AI-generated code, fast, programmatic sandboxes you drive through an SDK or platform. If you are operating that kind of platform, it is a capable tool.
xShellz Agent Shell answers a different, more personal question: "I use an AI coding agent, where do I let it actually run?"
Infrastructure vs. a box you own
Daytona is something you build on top of. Agent Shell is something you use directly: a cloud Linux box with root that you SSH into, that stays yours between sessions.
| Daytona | xShellz Agent Shell | |
|---|---|---|
| Model | Platform / SDK for sandboxes | A personal box you SSH into |
| Persistence | Task-oriented, ephemeral by default | Persistent home, always-on capable |
| Onboarding | Wire up the platform | Point your agent at it |
| Extras | none | turborg AI bots + borg CLI in the same account |
What you get with Agent Shell
- Root on a kernel-isolated box. Give an agent full control safely. It cannot escape to your machine or other users.
- Agent-neutral. Claude Code, Codex, Gemini CLI, borg, any MCP client, all connect over plain SSH. Nothing to integrate.
- Durable. Your
/homepersists; anxshellz.boxfile reproduces your setup on a fresh box. - Predictable cost. Flat monthly for always-on, plus a free pool of always-on hours to start. No surprise usage bill.
- A whole toolkit. The same account gives you turborg (an always-on AI bot for IRC, Discord, Telegram, Slack, and web chat) and borg, the command-line AI tool.
Which should you pick?
Running a fleet of sandboxes as part of a product you are shipping? Platform tooling like Daytona is built for that. Want your own always-on box to hand your coding agent, with your files kept and no SDK to wire up? That is Agent Shell.
