From repo URL to productive in minutes

Hootly reads the repo like a senior engineer — architecture first, then files, then the full picture.

Architecture Overview
Paste any repo URL and get the full architecture — tech stack, entry points, key directories, and how everything connects.
Key Files Ranked
Every source file is read and ranked by importance, weighted by how many other files import it. Know exactly where to start.
Interactive Dependency Graph
D3 force graph of real import connections. Color by language or directory. Click any node to highlight its links.
Suggested Reading Order
A step-by-step path through the codebase — tailored to the framework, architecture, and key files. Skip the guesswork.
AI Onboarding Guide
A full markdown guide covering project purpose, key workflows, how auth / routing / DB work, and where to start coding.
Codebase Health Report
Get an A-F health grade with scores for modularity, test coverage, documentation, and more. Share professional assessment reports.
Export & Share
Download the full analysis as Markdown, print to PDF, or share a public link in one click.
README Health Badge
Add a live health-grade badge to your README. Shows at a glance that the codebase is well-maintained.
Team Dashboard
Share analyses across your team. Everyone sees the same onboarding guides, health scores, and dependency graphs.
Use cases

Who uses Hootly

Teams, managers, investors, maintainers, and freelancers — anyone who needs to understand a codebase fast.

Onboard new engineers
New hire starts Monday. Paste the repo URL, share the onboarding guide. They're reading code by lunch, not hunting for the entry point.
Audit code health
Get an architecture health score across your repos. Spot structural debt, missing tests, and documentation gaps before they become problems.
Technical due diligence
Evaluating an acquisition or investment? Get the full architecture breakdown, health grade, and risk areas in minutes — not weeks.
Help contributors onboard
Add a health badge and onboarding guide to your open source project. New contributors understand the architecture before writing their first PR.
Ramp up on client codebases
Freelancers and consultants: paste the repo URL, read the guide, start billing for real work — not orientation.
