## What it is
Codapi is a lightweight Go-based sandbox server that executes code snippets in isolated Docker containers via an HTTP API, paired with a JavaScript widget for embedding interactive code examples. It lets documentation authors, course creators, and bloggers turn static code snippets into runnable playgrounds supporting 40+ languages, databases, and tools.

## Use cases
- embed runnable code examples in product documentation
- add interactive exercises to an online course
- let readers run code snippets in blog posts
- try out programming languages and databases in a safe sandbox
- self-host a code execution API for internal tools
- build custom playgrounds for any Docker-runnable software

## When to choose
- you write technical documentation or tutorials and want interactive examples
- you need sandboxed code execution across many languages via a simple API
- you want a self-hosted, open-source alternative to hosted playground services
- you need custom sandboxes built from your own Docker images

## When to avoid
- you need a full online IDE or persistent development environment
- you require high-throughput code execution with strict latency guarantees
- you cannot run Docker/Podman and need only in-browser execution for niche languages
- you need sandboxing with access to sensitive data (not recommended by the project)

## Facets
- artifact type: service
- maturity: active
- function: http-server, sdk, developer-tools, security
