| Tagline | VS Code fork that made AI coding actually work. | An open-source, MCP-native knowledge graph engine that gives AI coding agents (Cursor, Claude Code, Windsurf) genuine structural awareness of your codebase before they touch a single line. | Spreadsheets with AI + live integrations baked in. | French alternative. Fast, European, privacy-focused. |

| Best for | Developers. Non-developers who want to ship working code. | Developers working in large or unfamiliar codebases who want their AI coding agent to stop making confident, structurally blind edits — especially Claude Code power users. | Ops teams, marketers, anyone building dashboards from multiple sources. | European users with data residency needs. Fans of open-weight models. |

| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | GitNexus solves a real and underappreciated problem: AI coding agents are syntactically fluent but architecturally blind, and plugging a pre-computed knowledge graph into the MCP layer is the right fix. 28k GitHub stars in days suggests the pain is widely felt — just go in knowing it's a community project, not a polished product. (Verdict pending Phi's full review.) | A-tier. The most interesting spreadsheet in years. Great for ops dashboards. | B-tier overall, A-tier if GDPR/data residency matters. Solid backup option. |
