Block has released Goose, an open-source AI coding agent that performs the same tasks as Anthropic's Claude Code—for free. While Claude Code charges between $20 and $200 per month depending on usage, Goose offers equivalent functionality without any subscription cost.
The launch arrives at a charged moment for AI coding tools. Claude Code, released in May 2025, quickly became the most widely used terminal-based AI coding assistant, with approximately 95% of engineers now using AI weekly. However, the pricing has sparked backlash among developers who see the subscription as unnecessary overhead.
What Goose Offers
Goose operates as an autonomous "coding worker" that handles debugging, testing, bug fixes, and full code migrations without requiring constant user input. Unlike Claude Code, which locks users into Anthropic's models, Goose is model-agnostic—it supports Claude, GPT-5, and local LLMs through MCP (Model Context Protocol) servers.
The tool integrates with over 3,000 tools via MCP servers and includes features like "recipes" for workflow automation and "goosehints" for storing project preferences. Users report saving 8-10 hours weekly on development tasks.
Key Differences
- Pricing: Goose is completely free and open-source. Claude Code costs $20-$200/month.
- Model Support: Goose supports multiple models; Claude Code uses Anthropic models only.
- Deployment: Goose runs locally on your machine with no vendor lock-in.
- Customization: Goose offers recipes and sub-agents for parallel task execution.
Block has positioned Goose as a direct challenger to not only Claude Code but also GitHub Copilot and other commercial AI coding assistants. The company plans to expand capabilities with specialized agents like "Goose-SWE-Agent" for software engineering tasks throughout 2026.
