What E2B does
E2B runs secure, isolated Firecracker microVM sandboxes where AI agents execute code, use a shell, filesystem and browser, and run background jobs or RL rollouts. Developers control the sandbox lifecycle, network, storage and metrics through an SDK, in E2B's cloud or in their own AWS, GCP or Azure account. It is used by AI startups, model labs and enterprises building coding, data and computer-use agents.

LindyVendor case studyPublished May 19, 2025We 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 infrastructureYou are super reliable. There’s only been one outage I can think of in the past two years. You’re doing a really good job at reliability and support, and the product is really good. Just keep doing the exact same thing you’re doing.Before you buy E2B

How does usedby know who uses E2B?
Each company is linked to a public page that names it: E2B's customer page, a published case study, a press release or a job post. We save each page with a dated capture and check it again on each run. A company leaves the list only after three checks in a row that no longer find it, and at least 14 days after it was last seen. A company with a published case study or quote is never removed automatically.
What do confirmed, observed and signal mean?
Confirmed (15): a case study, a named quote or a press release. Observed (8): E2B shows the company on its own pages, for example a logo wall. Signal (0): a job post shows the company’s employees use E2B, the weakest proof. Every level counts as a customer, and each line shows its level.
How current is this list?
The most recent check was on October 6, 2026, and 23 of 23 companies on this list have been checked so far.
