E2B

E2B provides open-source, secure sandbox environments and virtual computers equipped with real-world tools specifically for AI agents and LLMs. The platform is designed to let developers safely run code, conduct deep research, analyze data, and power automated systems and agentic workflows. It is utilized by enterprises and developer platforms to run frontier agentic workflows.

• Run code safely inside secure, isolated sandbox environments
• Support for deep research agents to conduct time-consuming research on large datasets
• AI data analysis and visualization capabilities to explore data and generate charts
• Customizable Sandbox CPU and RAM options
• Configurable sandbox session lengths ranging up to 1 hour on Hobby and up to 24 hours on Pro
• Concurrent sandbox management supporting up to 20 concurrent sandboxes on Hobby, 100 on Pro, and up to 1,100 with extra concurrency purchases

Pros

• Provides enterprise-grade security and data protection for running AI agent code and workflows
• Offers flexible pricing with a free tier that includes initial credits and no credit card required
• Scales concurrency limits to accommodate up to 1,100 running sandboxes for heavier workloads
• Open-source nature provides transparency and community support for developers

Cons

• Hobby tier limits sandbox session length to a maximum of 1 hour
• Hobby tier restricts concurrency to 20 concurrently running sandboxes
• Pro tier requires a monthly subscription fee of $150 plus separate usage costs
• Custom enterprise solutions require contacting sales rather than self-service setup

E2B fits developers and organizations building automated systems, reinforcement learning routines, computer use agents, background agents, and secure Model Context Protocols (MCPs). It is well-suited for engineering teams at startups and enterprises needing isolated environments for LLMs. It is a poor fit for teams not utilizing AI agents or those requiring purely local execution without cloud-based sandboxes.

E2B operates on a freemium model with separate usage costs calculated per second of a running sandbox. The Hobby tier is free with no credit card required, including a one-time $100 of usage in credits, community support, up to 1-hour sandbox session lengths, up to 20 concurrently running sandboxes, and 10 GiB of storage. The Pro tier costs $150 per month plus usage costs, offering everything in Hobby plus customizable Sandbox CPU and RAM, up to 24-hour sandbox session lengths, up to 100 concurrently running sandboxes with the ability to purchase extra concurrency up to 1,100, and 20 GiB of storage. The Ultimate Enterprise tier offers a custom solution with special pricing available by contacting the company. Usage costs scale per second based on vCPU and memory configurations, with CPU rates starting at $0.000014 per second for 1 vCPU up to $0.000112 per second for 8 vCPUs, and memory c

Unlike general cloud hosting or standard virtual machines, E2B is purpose-built specifically for AI agents and LLMs with secure, isolated sandboxes and real-world tools. It allows autonomous systems to safely execute code and perform data analysis without risking host infrastructure. The platform pairs open-source accessibility with enterprise-grade scaling relied upon by major developer platforms and AI applications.

E2B is worth trying for developers and enterprises building agentic workflows who require secure, isolated sandboxes with flexible infrastructure limits. The platform provides a free Hobby tier with a one-time $100 usage credit, allowing users to test features without committing to a paid plan. However, teams should review the per-second usage costs and concurrency limits before scaling automated systems.
