Incremental engine for long horizon agents 🌟 Star if you like it!

Codebase intelligence for TypeScript and JavaScript. Free static analysis of code and styles: unused code, duplication, circular deps, complexity hotspots, architecture boundaries, design-system drift. Optional paid runtime layer (Fallow Runtime): hot-path review and cold-path deletion evidence from real production traffic.

Enterprise-grade (40m+ LOC) codebase intelligence, zero-setup, local & private Plugin/Skill/Extension or MCP: hybrid semantic search, polyglot dependency graphs, symbol-level impact analysis & call-flow, interactive HTML viewer, cross-project & branch-aware search, DB/API/infra knowledge. 61% less tokens, 84% fewer calls, 37x faster. Cloud in beta.

Persistent Intelligence Infrastructure for AI Agents

AI-native codebase intelligence skills — generate persistent .nexus-map/ knowledge bases and instantly query file structure, dependency graphs, and change impact. Built for Copilot, Cursor, and any tool-calling LLM. 面向 AI 编程助手的代码库感知技能——生成持久化知识图谱，精准查询文件结构、依赖关系与改动影响半径。

Agent skills for fallow, codebase intelligence for TypeScript and JavaScript. Teaches AI agents how to find unused code, duplication, circular deps, complexity hotspots, architecture drift, design-system drift, and (with Fallow Runtime) hot-path and cold-path evidence. Works with Claude Code, Cursor, Codex, Gemini CLI, and 30+ agents.

Structural intelligence for AI coding tools. Gives AI architectural context, blast radius analysis, domains, routes, and codebase impact awareness.

🌼 AI stack centered on an agent hypervisor. Automates tasks, runs graph-powered docs and Q&A, and searches across all your connected tools. Access it from browser, terminal, or API.

Local code intelligence. parse, index, and query any codebase with sub-200ms retrieval. Runs entirely on your machine.

Agent-facing Bicameral MCP tools for ingest, preflight, binding, and review commands

Structural Memory Protocol (SMP) — live structural code graph for scalable, safe AI agents.

Pi extension that brings Fallow codebase intelligence into Pi as an agent tool and slash command.

CLI-first TypeScript codebase analysis with hotspots, impact, dead-export detection, and architecture metrics. Includes optional MCP server for AI agents.

Documentation for fallow, codebase intelligence for TypeScript and JavaScript. docs.fallow.tools

Stop blind AI edits. Give agents callers, tests, routes, and blast radius before they change code.

A codebase intelligence substrate for architecture-aware agents, repository governance, and explainable software context.
