goose
goose is an Apache-2.0 open-source general agent under the Agentic AI Foundation, offering desktop, CLI, and API interfaces, multiple model providers, and MCP extensions for development and content tools.
Why use it
Beyond code edits, it can connect builds, analysis, documentation, and repetitive production tasks. Local execution, replaceable models, and custom extensions let indie teams reuse one agent framework across engineering, art pipelines, and pre-release checks with less dependence on one cloud vendor.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
MCP extensions and shell access amplify permission and supply-chain risk, so review every tool, isolate credentials, and retain human approval. The base software is free, but models, subscriptions, or remote services can cost money, and output and data terms vary by provider.
