graphify

Graphify-Labs/graphify · ★ 127.9K

Graphify turns a whole codebase — plus its docs, SQL schemas, configs, and PDFs — into a queryable knowledge graph you traverse instead of grepping files.

+154

Understand-Anything

Egonex-AI/Understand-Anything · ★ 86.8K

Understand Anything analyzes your codebase (or a knowledge-base/wiki) with a multi-agent pipeline and turns it into an interactive knowledge graph of every file, function, class and dependency, which you can explore in a visual dashboard.

+103

TencentDB-Agent-Memory

TencentCloud/TencentDB-Agent-Memory · ★ 29.5K

A team-level memory hub for AI agents. It turns conversations, docs, and code into four reusable memory assets — Chat Memory, Skills, Wiki, and CodeGraph — that agents across a team can share, govern, and equip.

+78

Trail-Code

trailhq/Trail-Code · ★ 10.3K

Graft maps your codebase into linked markdown files — one node per system, API, or concept — and feeds the matching nodes to coding agents like Claude Code, Cursor, Codex, and Gemini, so they stop re-exploring the repo on every task and run faster, cheaper, and more accurately.
