Do the people shaping Goose know how to drive it? Alex and Spencer usually build Goose. Now they’re stepping into the prompt arena to build with it in under 10 minutes. Who will guide Goose to the better build? 📆 June 24 at 10am PT/1pm ET 📺 linktr.ee/blockopensource

“Something like Goose had to exist.” According to @solomonstre (co-founder of Docker and Dagger), Goose stands out in a sea of AI tools with no strings attached. It’s open source, decoupled, and built for developers. 🎥 Full video in the thread

What if every idea had its own sandbox? Mic Neale’s using Dagger's Container Use MCP server with Goose to build isolated dev environments for safe testing, fast refactors, and side-by-side experiments. https://block.github.io/goose/blog/2025/06/19/isolated-development-environments

Goose is open source, local, and designed to speed up how you build. Join us in Toronto, where W. Ian Douglas will be your guide to getting started. 📍 Toronto, Canada 📅 June 24 at 6pm ET 🔗
