Open-source runtime for executing AI-generated code in secure cloud sandboxes.
E2B is an open-source runtime for executing AI-generated code in secure cloud sandboxes. Made for agentic & AI use cases. We built E2B with the next generation of developers in mind — software engineering AI agents. Sandboxes are powered by Firecracker microVM, a VM made for running untrusted code. The E2B Sandboxes in the same region as the client start in less than 200 ms. Each E2B sandbox can run up to 24 hours. Deploy E2B in your AWS, or GCP account and run sandboxes in your VPC.
AI Agent Server for the Enterprise
Add your AI agent to our curated directory
Handle multi-step workflows autonomously
Example
Schedule meeting → Find time → Send invite → Confirm attendees
Save 5-10 hours/week on routine coordination tasks
Gather data from multiple sources and summarize
Example
Research competitor pricing across 5 websites, create comparison table
Reduce research time from hours to minutes
Analyze options and recommend actions
Example
Review 20 vendor proposals, score against criteria, rank top 3
Make data-driven decisions faster
AI agents combine large language models with tools, memory, and decision-making logic to autonomously complete multi-step tasks without constant human guidance.
Large language model for reasoning and decision-making
Understand tasks, plan steps, generate responses
APIs, databases, external services the agent can call
Take actions beyond text generation (search, compute, write files)
Short-term (conversation) and long-term (persistent) memory
Maintain context across interactions and learn from past actions
Decision engine for choosing next action
Plan multi-step workflows and handle errors/edge cases

E2B reduced evaluation time — saves/upvotes on explainx.ai correlated with fewer surprises in the trial.
Solid agent profile: E2B links out cleanly and the on-site reviews add signal beyond marketing copy.
E2B has been stable for production-ish demos; the explainx.ai page was a useful single link to share internally.
