Serverless sandboxes for AI agents. Every agent gets a persistent Space, and each command runs in a fresh microVM that exists only while it runs, billing only
About Shark Magic
Shark Magic provides serverless sandboxes designed for AI agents. Each agent gets a persistent Space to store its files and databases, while every command runs in a fresh Firecracker microVM that exists only while executing, eliminating billing for idle time and model thinking.
Two products serve different use cases: Shark API offers an HTTP API with Python and TypeScript SDKs for teams running agents in their own products (early access), while Shark devbox provides a CLI tool for coding agents to have their own computer. Commands bill at $0.12 per compute-hour, calculated per second only while running.
The platform includes features like content-addressed file storage, sleeping services that wake in milliseconds, fork capabilities for Spaces, and key isolation to keep API keys outside VMs. It integrates with popular frameworks including LangChain, LangGraph, smolagents, and Prefect, and works unmodified with Claude Code and Codex through a shell shim.

FAQ
- What is Shark Magic?
- Serverless sandboxes for AI agents. Every agent gets a persistent Space, and each command runs in a fresh Firecracker microVM that exists only while it runs, with billing only for those seconds.
- What's the difference between Shark API and Shark devbox?
- Shark API is for teams running agents in their own product with an HTTP API and Python and TypeScript SDKs in early access. Shark devbox gives coding agents their own computer through a CLI at $5/month with $5 of usage included, with commands billed at $0.12 per compute-hour only while they run.
- How is Shark different from a regular sandbox?
- A regular sandbox stays up and bills for the whole task, while Shark keeps the Space and runs a microVM only for each command at the size chosen. While the model thinks, no VM runs.
- What is a Space?
- The agent's persistent space for its files and databases, stored by content, with services that sleep between requests. A Space can be forked fast and read without booting a VM.
- How is that different from a regular sandbox?
- A regular sandbox stays up, and bills, for the whole task. Shark keeps the Space and runs a microVM only for each command, at the size you choose. While the model thinks, no VM runs.
