AGPL-3.0 · Open Source · Self-hostable
Understand any codebase
in seconds.
Paste a GitHub repo URL to instantly explore its dependency graph, git intelligence, hotspots, ownership, and more.
One engine, three interfaces
Install once. Choose the interface that fits your workflow — or use all three. They share the same data, the same intelligence, the same stores.
CLI
For the solo developer
pip install repowise. Run init, update, search, dead-code, and 10 more commands. Works fully offline with Ollama. Your code never leaves your machine.
MCP Server
For AI-native workflows
8 tools that plug into Claude Code, Cursor, or Cline. Your AI agent calls get_context() instead of reading 40 files. Config auto-generated after repowise init.
Web UI
For the whole team
Browse the wiki, explore the dependency graph in D3, view hotspot tables, track doc freshness, and chat with your codebase. All served from repowise serve.
Most tools answer one question.
repowise answers four.
Graph structure, git history, generated documentation, and architectural decisions — four layers that compound into genuine codebase understanding.
Every dependency, ranked and traced
repowise parses your codebase into a directed dependency graph using tree-sitter ASTs across 10 languages. PageRank identifies your most critical symbols. Community detection discovers logical modules even when directory structure doesn't reflect them.
- 6,284+ nodes with PageRank, betweenness centrality, SCC detection
- Edge types: imports, calls, inherits, implements, co-changes
- Topological sort drives generation order — bottom-up, always
- Scales to 30K+ nodes with automatic SQLite-backed graph
History that writes the documentation
GitIndexer mines your commit history to classify files as hotspots or stable, compute ownership, extract significant commit messages, and discover co-change partners. These signals flow into generation prompts, so your wiki explains why code was written — not just what it does.
- Hotspot detection: top 25% churn + complexity files flagged
- Co-change partners: files that change together without imports
- Ownership from git blame — primary owner + top 3 contributors
- Significant commits filtered and included in generation prompts
Wiki pages that stay fresh
Each wiki page is generated with 9 layers of context: source code, symbol signatures, graph metrics, git history, import summaries, RAG context, co-change docs, dead code findings, and reverse imports. Confidence scores decay when source changes — stale pages auto-regenerate.
- Confidence scoring: 0.0–1.0 with git-informed decay modifiers
- RAG context via LanceDB or pgvector — each page knows its imports
- 9-level hierarchical generation: symbols → files → modules → repo
- Resumable jobs — crash-safe, idempotent, checkpoint after every page
The why behind your architecture
Decisions are extracted from four sources: inline markers (# WHY:, # DECISION:, # TRADEOFF:), git archaeology, README/docs mining, and manual CLI capture. Each decision tracks staleness — when affected files change, the decision is flagged for review.
- 4 capture sources with confidence: inline (0.95), git (0.70–0.85), docs (0.60), CLI (1.00)
- Staleness tracking — decisions age when governed files get commits
- Health dashboard: stale decisions, ungoverned hotspots, proposed reviews
- MCP tool get_why() searches decisions before you change anything
The full picture, side by side
Most tools solve one slice of the problem. repowise is the only open-source platform that combines auto-generated documentation, git intelligence, decision records, and MCP tools in a single self-hostable package.
