Everything You Need for
Secure Code Execution

From AI agent orchestration to enterprise CI/CD pipelines, Vibe Engine provides the foundational infrastructure for running untrusted code at scale.

🔒

Firecracker MicroVMs

Each sandbox runs in its own Firecracker microVM with hardware-level isolation. Sub-millisecond startup, zero blast radius. The same technology that powers AWS Lambda and Fly.io.

Zero Cold Starts

Pre-warmed VM pools and snapshot-based restoration ensure your sandboxes are ready in under 500ms. No waiting, no queuing — instant execution for latency-sensitive AI workflows.

🌐

Full Network Access

Sandboxes get outbound internet access by default with configurable network policies. Install packages, call APIs, scrape websites — all within an isolated, monitored environment.

📦

Custom Templates

Start from pre-built images (Python 3.12, Node 20, Go 1.22, Rust, Java 21) or bring your own Dockerfile. Pin dependencies, pre-install libraries, and configure environments exactly how you need.

📈

Elastic Scaling

Scale from 1 to 10,000+ concurrent sandboxes automatically. Per-second billing, no reserved instances. Our orchestrator intelligently distributes workloads across our 6 generally available regions.

🔄

Real-time Streaming

Stream stdout/stderr in real-time via WebSocket or SSE. Get line-by-line output from long-running processes, interactive debugging sessions, and AI agent execution traces.

🗄️

Persistent Volumes

Attach durable storage volumes to sandboxes for stateful workflows. Snapshot, restore, and share filesystems across sandbox instances with sub-second mount times.

🔍

Full Observability

Built-in metrics, logs, and traces for every sandbox execution. OpenTelemetry-compatible. Dashboards, alerts, and audit trails for compliance-ready enterprise deployments.

🤖

AI Agent SDK

First-class integrations for LangChain, CrewAI, AutoGen, and OpenAI Assistants. Let your AI agents safely execute code, install packages, and interact with the filesystem.

Built for Enterprise-Grade Workloads

A multi-layered architecture designed for security, performance, and reliability at scale.

  • Hardware-level isolation — each sandbox is a dedicated microVM, not a container. No shared kernel, no escape vectors.
  • Multi-region deployment — run sandboxes closest to your users across 12 PoPs in US, EU, APAC, and Singapore.
  • Snapshot & restore — freeze sandbox state to persistent storage and restore in <200ms. Perfect for long-running AI agent sessions.
  • Network micro-segmentation — granular egress policies per sandbox. Allow, deny, or audit outbound traffic at the domain and port level.
  • Automatic resource limits — CPU, memory, disk, and network bandwidth caps per sandbox. No runaway processes, no noisy neighbors.
  • SOC 2 Type II & GDPR ready — audit-logged API access, encrypted volumes, data residency controls, and 90-day log retention.
