# Amp > Agentic coding tool built by Sourcegraph that provides autonomous reasoning, comprehensive code editing, and complex task execution in VS Code, Cursor, Windsurf, and CLI. Amp is an advanced agentic coding tool built by Sourcegraph that maximizes what's possible with today's frontier models. It features autonomous reasoning, comprehensive code editing, and complex task execution capabilities. Available as VS Code extension (compatible with Cursor, Windsurf, and VSCodium) and as a command-line tool. Amp uses Claude Sonnet 4 for most tasks with up to 432,000 tokens of context. It supports thread sharing for team collaboration, subagents for complex tasks, and includes Amp Tab completion engine. The tool can run commands, edit files, understand code, and execute multi-step workflows autonomously. It features prepaid credit system with no model selectors - always uses the best available models. ## Features - AI-powered code generation and editing - Claude Sonnet 4 integration with 432k token context - VS Code, Cursor, and Windsurf extension - Command-line interface (CLI) - Thread sharing and team collaboration - Autonomous task execution and reasoning - Subagents for complex multi-step tasks - Amp Tab completion engine - File editing and code review - Terminal command execution - AGENTS.md guidance files - Image upload and analysis - Extended thinking capabilities - Multiplayer collaboration - Context management and thread compaction - MCP (Model Context Protocol) support - Oracle integration for complex reasoning - JetBrains IDE support - Built-in permissions system - Secret redaction for security ## Integrations VS Code, Cursor, Windsurf, VSCodium, Anthropic Claude, OpenAI, JetBrains IDEs, Google Cloud Vertex AI, Amazon Bedrock, Fireworks, Baseten, GitHub, GitLab, MCP servers, Playwright, Linear, Semgrep ## Platforms WEB, VSC_EXTENSION, API, JETBRAINS_PLUGIN ## Pricing Subscription-based ## Version 0.0.1756238480-g6dfbfa ## Links - Website: https://ampcode.com/ - Documentation: https://ampcode.com/manual - EveryDev.ai: https://www.everydev.ai/tools/amp
