Core features
CodeSandbox offers isolated cloud development environments for coding, collaboration and shipping projects of any size from any device. Environments run separately so untrusted code stays contained, while many sandboxes operate in parallel without interference. Infrastructure provisions, manages and decommissions virtual machines at scale, with fast creation, cloning and snapshot restoration. Sandboxes hibernate after inactivity and resume later without loss, and controls adjust hibernation timing. Uses include AI agents, development at scale, code interpretation, evaluations and repeated test runs.
How CodeSandbox compares
Frequently asked questions
What is CodeSandbox?+
CodeSandbox provides a cloud development platform for coding, collaborating and shipping projects from any device. It focuses on isolated sandboxes that run code separately for safety and parallel work.
What does CodeSandbox sell or provide?+
CodeSandbox creates isolated development environments that execute many types of code without affecting host systems. Teams use the environments for parallel development, testing and evaluation across developers or students.
How does CodeSandbox support AI agents?+
CodeSandbox supports AI agents that resolve prompts, run autonomously and operate in parallel without interference. Forking also allows different agents to run side by side for direct evaluation.
How does CodeSandbox handle speed and resuming work?+
CodeSandbox uses microVM infrastructure to spin up, clone and restore environments and snapshots. Hibernated sandboxes resume later without loss, while controls manage inactivity before hibernation starts.
