Anvil is an open-source IDE that enables developers to run multiple AI coding agents in parallel, optimizing workflows and reducing context-switching to maximize productivity and minimize merge conflicts.
What is Anvil?
Anvil AI is a specialized open-source desktop integrated development environment (IDE) designed to streamline the management of multiple AI coding agents working in parallel. Developed to address the challenges faced by software engineers and developers who use AI agents like Claude, Anvil offers a unique architecture centered on isolated git worktrees and native markdown-based spec support. This approach prevents merge conflicts and aligns teams on project architecture before code execution. The platform integrates a terminal, file editor, and diff viewer into a unified interface, enhancing workflow optimization and business automation. Anvil’s REPL and orchestration features allow one AI agent to programmatically call others, enabling complex multi-phase task execution. By reducing manual overhead and human context-switching, Anvil transforms a single developer into an AI engineering team manager, significantly boosting SMB efficiency.
