Capabilities

Powerful Features Built for Integration

Run and compile code directly inside your website with ready-made widgets and developer-friendly layouts.

Online Run Environment

Give users the fully responsive coding sandbox with real-time terminal input support for seamless execution.

Multi-Language Support

Our sandbox backend executes script blocks for 34 languages including Python, C++, Java, and Go.

Real-Time Streams

Low-latency WebSocket connections stream outputs, syntax warnings, and compile results back instantly.

Layout Studio Customizer

Design beautiful compiler templates to perfectly match your brand's aesthetics without complex code configurations.

Technical Writers Ready

Double reader engagement rate by embedding interactive compiler sandboxes directly inside documentation and blogs.

Domain-Locked HMAC Security

Protect your container runs and credits with secure backend HMAC signatures and domain locking configurations.

AI Sandboxes & MCP Platform

Connect LLMs and AI autonomous agents directly to secure execution workspaces. Use Server-Sent Events (SSE) to let models read, write, and execute code within completely isolated sandbox containers.

Two Paths to Quick Integration

Choose between an ultra-lightweight client-side JS SDK or configure low-latency WebSocket TCP connections.

1

Add JavaScript SDK

Paste a generated Embedenv script tag inside your page's head container; set the data-key parameter to authenticate.

2

Tag Code Containers

Wrap standard code snippets using classes like 'embed-code-block'. Designate run languages via data attributes.

3

Execute & Run Code

The compiler loader intercepts a container, initializes secure sandboxes, and streams an execution feeds instantly.

Plans

Simple Credits-Based Pricing

Only pay when users execute code. Loading scripts, embedding elements, and styling layouts are always 100% free.
