Case Study: Anything scales to 1M+ users with E2B's cloud sandboxes

Anything powers app generation for 1M+ users with E2B

The customer Anything, a platform enabling users to build apps without code, faced the challenge of providing its AI agents with a complete development environment that could instantly scale for its over one million users. Their infrastructure needed to spin up thousands of isolated, real developer workstations on demand to handle unpredictable, viral growth without introducing latency, a task they initially considered building in-house.

The vendor E2B provided its solution, giving each user session a lightweight MicroVM that behaves like a real Linux computer. This allowed Anything's agents to use standard development tools and package managers. The results included support for thousands of concurrent sandboxes and over one million users, while saving the company an estimated 2-3 senior infrastructure engineers over several months.
