garrytan/gstack

Choose this fork if you are committing to Google Antigravity and want a gstack-like workflow pack adapted for it. Choose upstream if you want the fuller, faster-moving, broader Claude Code implementation with more complete tool coverage.

Choose this fork if you want gstack adapted specifically for C++ work and integration-heavy automation. Choose upstream if you want the broader, more current, general-purpose Claude Code workflow with the latest skills and fixes.

Choose this fork if OpenCode compatibility matters more than upstream freshness. Skip it if you want the newest gstack skills, fixes, and Claude Code-native workflows.

Prefer upstream if you want the most complete and current gstack. Prefer this fork only if you specifically want a slimmer, older subset and do not need the newest specialist workflows.

Choose this fork if you want a smaller Antigravity-focused version of gstack and do not need the newest upstream capabilities. Stick with upstream if you want the full, actively evolving 23-tool workflow system and fewer compatibility risks.

Choose this fork if you want a pared-down gstack baseline and can accept lag versus upstream. Choose upstream if you want the latest tools, security fixes, and the full specialist workflow set.

Choose this fork only if you intentionally want a slimmer, older variant of gstack. Otherwise, upstream is the better default because it is much more feature-complete and actively moving, while this fork looks like a lagging snapshot with no clear added capabilities.

Choose the upstream if you want the full, actively evolving gstack. Choose this fork only if you specifically want a slimmer 15-tool setup and can accept being 32 commits behind with missing recent capabilities.

Prefer upstream unless you need a pinned snapshot. This fork does not add visible capability, and it is materially behind on skills, compatibility, and security/workflow fixes.
