StackAI and E2B have partnered to bring secure, isolated code execution to enterprise AI agents in regulated industries.

The partnership now powers three core capabilities on the StackAI platform. Custom Code lets users execute Python or JavaScript inside agent workflows, with every run automatically sandboxed. Computer Use and RPA replays recorded desktop sessions inside E2B sandboxes so agents can operate enterprise software securely and reliably. Browser Use keeps web navigation and scraping sessions fully isolated.

"With E2B, it's really easy to provision sandboxes. They're secure by default, highly capable, and very performant," says JJ Miller, Senior Product Manager. "Sandboxes are a key primitive for agents going forward. For us to keep growing as a company, we need a partner that can grow with us. We're happy to have found one in E2B."

The collaboration scaled quickly, going from a few sandboxes during evaluation to hundreds of thousands in production. And it's set to deepen, according to JJ: "Sandboxes are a key primitive for agents going forward. For us to keep growing as a company, we need a partner that can grow with us—we’re happy to have found one in E2B."
