Micro VM.
Macro Power.
Sub-90ms cold boot. Firecracker microVMs with hardware-level isolation.
E2B-compatible SDKs. 100% EU hosted.
Built for speed.
Lelantos is an E2B-compatible sandbox platform for AI Agents, beautifully isolated on Firecracker microVMs. Bringing hardware-level security with sub-90ms boot, EU data residency, and per-second billing — works seamlessly with any LLM framework, AI agent, or automation pipeline.
* The Creation of Adam, Michelangelo, c. 1512Built for AI agents, LLM training, and MCPs.
Secure, isolated compute for any AI workflow. Hardware-level isolation with Firecracker microVMs — not Docker, not containers.
ExploreAutonomous Research
Let agents browse, scrape, and synthesize — running hours-long research tasks inside isolated VMs with full filesystem persistence.
Data Exploration
Spin up secure sandboxes to run Pandas, plot charts, and analyze sensitive datasets without exposing your infrastructure.
Code Execution
Execute untrusted code with hardware-level isolation. Full I/O, internet access, and terminal — auto-cleaned on exit.
Rapid Prototyping
AI generates the app, the sandbox runs it live. Ship MVPs and creative tools with any language or framework.
Batch Evaluation
Spawn thousands of parallel sandboxes for reward function evaluation, test suites, or large-scale simulations.
Browser Automation
Give your LLM a full Chromium environment. Automate web tasks, fill forms, take screenshots — all sandboxed.
