60%
“More than 60% lower customer latency for heavy Replicas workloads after moving to E2B.”

What happened
Replicas runs coding agents in the cloud for engineering teams, starting an agent from a Slack message, Linear ticket or GitHub pull request tag. Each agent runs in an E2B sandbox started from a snapshot of the customer's prepared workspace, so it can build, run services and return a pull request.
Summary written by usedby from the source page, in English. The figures are those of E2B and Replicas, not ours.
- Three weeks“Three weeks saved on sandbox debugging during the final stretch of YC and fundraising.”
- 20“More than 20 YC companies now run engineering work through Replicas.”
Replicas captures each customer's configured workspace as an E2B Snapshot, including the cloned repository, installed dependencies, and development setup. When somebody pings Replicas in Slack or assigns it a Linear ticket, Replicas starts a new sandbox from that snapshot.
Reliability is the only thing that matters, and lack of reliability was the main reason for churn at Replicas. You want to pick infrastructure that's never going to let you down, so you have time to work on the thing that matters most: the agent experience.
