Introduction

Welcome to Amplify : a free, open-source AI coding assistant you can self-host. It runs entirely in your browser using a WebContainer-based sandbox, connects to 22+ LLM providers, and lets you extend the AI with built-in skills and MCP servers.

What is Amplify?

Amplify is an AI-powered coding assistant that gives you a full development environment inside your browser — a code editor, terminal, file explorer, and live preview — all connected to an AI that can read files, write code, search the web, and execute commands.

Built on the Open_Claude open-source project, Amplify uses a Remix-based frontend (SvelteKit-compatible architecture) with the Vercel AI SDK v7 for LLM communication, WebContainers for browser-native sandboxing, and a sophisticated planning engine for multi-step code generation.

Self-hosted by default

Amplify is designed to be self-hosted. You own your data, your runtime, and your configuration. No third-party service has access to your code or AI conversations. All data persists in IndexedDB on your own machine.

Goals and philosophy

Amplify was built with three core principles:

  1. Open_source_forever : MIT licensed, no hidden restrictions, community-driven development
  2. Self-hosted by default : your code stays on your machine; no vendor cloud storage
  3. Extensible by design : 22+ LLM providers, 8 skills, MCP servers, custom providers

The project believes that AI coding tools should not lock you into a single provider or platform. You should be able to swap between OpenAI, Anthropic, Google, Ollama, or any OpenAI-compatible endpoint without changing your workflow.
