### Gemini-only stacks (1)

- [Indie SaaS (Gemini long-context)](https://aistack.sh/stack/indie-saas-gemini) — Different ergonomic from the Claude-led pair: instead of pasting individual files per turn, dump the entire repo into Gemini and let it reason across the whole graph. Claude takes over for tight, surgical edits; Gemini handles 'change auth across 14 files' moves.
