How StackAI uses E2B

As published on e2b.dev, June 2026. Captured by usedby on Oct 6, 2026.

What happened

StackAI runs the code that its customers' and LLMs' agent workflows generate inside isolated E2B sandboxes. It uses them for custom Python and JavaScript code, computer use and RPA replays, and browser-based agent sessions for customers in regulated industries.

Summary written by usedby from the source page, in English. The figures are those of E2B and StackAI, not ours.

Custom Code. Users write and execute Python or JavaScript directly inside agent workflows through the Code Node. E2B handles the sandboxing, so every execution runs in a secure, isolated environment regardless of workflow complexity.

We built our own code sandbox VM, and it neither scaled well nor had all the features we needed. We couldn’t afford the time to take away from building revenue-generating features for 5-6 of our platform engineers to build and maintain the infrastructure
