goose

Block quietly built an open-source dev agent that actually does the work instead of just suggesting it, and the numbers don't lie — 35.9k stars on GitHub is the kind of organic traction that happens when a tool genuinely works. What's clever here is that Goose pairs with literally any LLM, runs as a desktop app or CLI, and its MCP server integration means you can plug it into your existing stack without locking yourself into someone's ecosystem. It's Apache-2.0 licensed, so there's no catch, and the multi-model configuration lets you optimize for speed or quality depending on what you're building — which is a real quality-of-life win for developers managing complex pipelines. If you're still manually triaging code suggestions while an agent could be scaffolding entire features for you, that's the kind of workflow friction that nobody should be tolerating in 2025.
