⚡ Core Capabilities

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 12 global 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.

  • ✓
    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.

❓ FAQ

Frequently Asked Questions

What is Vibe Engine? +

Vibe Engine is an enterprise-grade cloud platform that provides isolated coding sandboxes powered by Firecracker microVMs. It enables AI agents, development teams, and CI/CD pipelines to execute code in secure, ephemeral environments with sub-500ms launch times.

How does Firecracker isolation differ from containers? +

Containers share the host kernel, which creates potential escape vectors. Firecracker microVMs provide hardware-level isolation with a dedicated kernel per sandbox. Each VM has its own memory space, network stack, and filesystem — eliminating shared-state risks entirely.

What programming languages and runtimes are supported? +

Vibe Engine supports Python 3.12, Node.js 20 LTS, Go 1.22, Rust, and Java 21 out of the box. You can also bring your own Dockerfile to create custom templates with any language or runtime your workload requires.

Can I install packages inside a sandbox? +

Yes. Sandboxes have full outbound internet access by default (configurable via network policies). You can run pip install, npm install, or any package manager. Installed packages persist for the sandbox lifetime, and you can snapshot the state for later reuse.

How fast can a sandbox launch? +

From API call to a fully ready sandbox, typical launch time is under 500ms. We maintain pre-warmed VM pools and use snapshot-based restoration to eliminate cold starts for common templates.

What AI frameworks integrate with Vibe Engine? +

Vibe Engine has native integrations for LangChain, OpenAI Assistants, CrewAI, AutoGen, and Claude MCP. Our Python and JavaScript SDKs make it straightforward to add sandbox execution to any agent framework.

Is my data encrypted? +

All data is encrypted with AES-256 at rest and TLS 1.3 in transit. Persistent volumes and snapshots use customer-managed encryption keys. We do not access or inspect sandbox contents.

What compliance certifications does Vibe Engine hold? +

We are working toward SOC 2 Type II certification and are GDPR-ready with data residency controls, DPA availability, and right-to-erasure support. HIPAA-ready configurations are available for healthcare workloads on request.

How does pricing work? +

Vibe Engine uses per-second billing based on the compute resources allocated to each sandbox (CPU, memory, disk). There are no reserved instances or upfront commitments. Contact our sales team for volume pricing and enterprise agreements.

Where are sandboxes hosted? +

We operate across 12 global regions including US (East & West), EU (Frankfurt, London), and APAC (Singapore, Tokyo, Sydney). Enterprise customers can request dedicated infrastructure in specific regions for data residency requirements.

Can I self-host Vibe Engine? +

Vibe Engine is currently offered as a managed cloud service. For enterprise customers with strict data sovereignty requirements, we offer dedicated single-tenant deployments within your preferred cloud provider. Contact our enterprise team for details.

How do I get started? +

Book a demo with our team to discuss your requirements and get access to the platform. We will set up a dedicated workspace, provide API keys, and walk you through your first sandbox deployment. Our documentation at docs.vibengine.cloud covers SDK setup, templates, and API reference.
