Pacta

Architecture Insights, Governance & Versioned Design

GitHub License

Warning: Experimental. Expect breaking changes until release 0.1.0

Pacta turns software architecture into versioned, queryable data — so teams can see, compare, and reason about architectural change over time, not just block violations.

pip install pacta

Pacta Demo

Supported languages:

Python
Java (coming soon)
Go (coming soon)
C# (coming soon)

Why?

Codebases rot. Architecture degrades through small changes no one tracks. Pacta turns architecture into something measurable, reviewable, and enforceable — catching drift early, not months later.

What it does

Architecture snapshots — version your architecture like code
History & trends — track how dependencies, coupling, and violations evolve over time
Diffs — compare architectural states like Git commits
Metrics & insights — nodes, edges, layers, instability, drift
Rules & governance — express architectural intent and enforce it incrementally
Baseline mode — govern change without being blocked by legacy debt

Think of Pacta like Git for architecture

Git	Pacta
`git add`	`pacta snapshot save` — capture an architectural snapshot
`git commit --verify`	`pacta check` — evaluate rules against a snapshot
`git commit`	`pacta scan` — snapshot + check in one step
`git log`	`pacta history` — timeline and trends of architectural states
`git diff`	`pacta diff` — compare two snapshots
branch protection	`rules.pacta.yml` — governance that prevents drift

See the Getting Started guide for a full walkthrough.
