Open Agents

Open Agents is a cloud platform for running autonomous coding agents. A user describes what to build and an agent works through it in its own sandbox with filesystem, network and runtime access, using built in tools for file operations, search, shell commands and task delegation. Explorer and executor subagents can work in parallel. Each session runs in an isolated Vercel sandbox on its own git branch, and work is committed and pushed automatically so nothing is lost when the sandbox expires. Environments hibernate on inactivity and restore quickly, and filesystem state can be snapshotted and restored. Agent loops run as durable workflows that checkpoint progress, retry on failure and let a client reconnect to a running job. After a run finishes, the platform records usage, caches diffs and commits the result. The stack is built on Vercel's AI SDK, AI Gateway, Sandbox and Workflow SDK, with multi model support through the gateway. The demo interface shows sessions running Claude models. Sign in is through a Vercel account, and the site labels the project open source. The site does not publish plans or prices. The only cost figure shown is an illustrative sandbox cost inside the interface mockup, which is not a pricing statement.
