Technical Use Cases
1. Secure Code Execution for Coding Agents Deploy sandboxed microVMs as the execution backend for coding agents (e.g., Codex, Cursor, Devin). Each agent session gets an isolated Firecracker VM, preventing cross-session contamination and enabling safe arbitrary code execution.
2. Long-Running Agentic Workflows Use Pro or Enterprise tiers to run agent sessions up to 24 hours or multi-day. Leverage pause/resume and snapshot APIs to checkpoint agent state, enabling resilient, restartable pipelines without restarting from scratch.
3. Parallel Agent Execution at Scale Fork a base sandbox snapshot to instantiate hundreds or thousands of parallel agent instances from a consistent starting state. Enterprise tier supports tens of thousands of concurrent sandboxes for large-scale evaluation, simulation, or multi-agent systems.
4. MCP Tool Integration Connect agents to any of 200+ MCP servers through E2B's native MCP support, giving agents access to a broad ecosystem of tools within isolated, controlled environments.
5. BYOC Enterprise Deployments For organizations with strict data residency or compliance requirements, deploy E2B's runtime inside your own AWS, GCP, or Azure account. Combine with SOC 2 Type II and HIPAA compliance for regulated workloads.
6. Agent Framework Agnostic Compute Layer Use E2B as the compute substrate beneath any agent stack — OpenAI Agents SDK, Anthropic Claude, open-weight models — without being locked into a single provider's execution environment.
