Git-native history scanning
Walk first-parent history with gix (pure Rust). Store per-commit snapshots locally and reuse cache on repeated scans.
Open-source architecture analysis
See the structure
your repo hides
MorphArch scans Git history, builds dependency graphs, computes health scores, and helps you inspect structure, drift, and hotspots — all from a terminal UI designed for large codebases.

Capabilities
Everything you need to understand your architecture
MorphArch is designed for repeated local analysis — not a one-time graph dump, but an operational tool for ongoing architecture review.
⟡
Language-aware parsing
Extract dependency edges from Rust, TypeScript, JavaScript, Python, and Go with comment-safe fast paths and tree-sitter AST fallback.
◈
Scale-aware health scoring
Six-component 0–100 health score that adapts baselines for repository size. No false positives on large monorepos.
◎
Blast radius analysis
Inspect downstream impact for high-risk modules. See which changes are likely to ripple through the dependency graph.
▦
Cluster-first navigation
Start with a grouped map view. Drill into cluster details and then individual modules — never start with raw graph chaos.
⬡
AI architecture assistant
Ask natural language questions about health, coupling, hotspots, and blast radius. Works with OpenAI, Ollama, or any compatible API.
Health scoring
A 0–100 score built from six debt components
Each component is weighted, scale-aware, and configurable. The score adapts its baselines to your repository size.

Navigation model
Structure before raw detail
Large repositories are easier to review when you start at the cluster level. MorphArch keeps the raw graph available, but only surfaces it when you need it.
01
Map
Start with grouped clusters so large repositories are readable before looking at individual nodes.
02
Cluster details
Open a subsystem to inspect members, dependencies, and link pressure between clusters.
03
Inspect
Focus one module with a one-hop subgraph. See who depends on it, what it pulls in, and its blast radius.
AI Assistant
Ask your architecture questions in plain language
Press a in the TUI to open the AI panel. It uses the full architecture context — health scores, dependency edges, blast radius, churn hotspots, cycle groups — to answer your questions.

AI Assistant
You:What is the riskiest module?
AI:parser/resolver has the highest blast score (0.72) with 14 downstream dependents. It sits in a cycle with graph_builder and has instability I=0.89. Consider extracting the shared types into a leaf module to break the cycle and reduce ripple risk.

Built for people who care about architecture
Architects
Review boundaries, coupling, and structural pressure without manually reading a full dependency graph.
Tech Leads
Track drift over time, review what changed between commits, and identify parts of the repo that are becoming harder to change.
Developers
Answer practical questions — who depends on a module, what it pulls in, and what changes are likely to ripple outward.
