Free Stack Review

Get an instant health check on any project — no account, no credit card, no strings attached. Otto scans your project metadata and returns a scorecard showing where you stand against industry best practices.

What Otto Scans

The free review collects metadata only — it never reads your source code. Specifically, Otto looks at:

• Package manifests and dependency lists (package.json, requirements.txt, pom.xml, etc.)
• Configuration file presence (linting, testing, CI/CD, Docker, monitoring)
• File type distribution (languages, frameworks detected)
• Git configuration and branch structure
• Security tooling presence (scanning, secrets detection, dependency audit)

What Your Source Code Never Leaves Your Machine

Otto's architecture is designed around a simple principle: your code stays on your machine. The extension sends only the metadata listed above to the Otto cloud server. The server runs assessment logic and returns computed results. No source code, no business logic, no proprietary content is ever transmitted.

Reading Your Scorecard

Your scorecard includes an overall score (0–100), a letter grade, and findings organized by severity:

Free vs. Paid

The free review shows you what's wrong — your score, grade, and findings. A paid subscription unlocks the how to fix it — detailed remediation plans, automated setup agents, ongoing monitoring, and continuous modernization. Think of the free review as the diagnostic; the subscription is the treatment plan.

Why Otto Teaches

Every finding in your scorecard explains why it matters, not just what to fix. Otto references the industry standard behind each recommendation (OWASP, DORA, 12-Factor, etc.) so your team learns current best practices through using Otto. Whether you subscribe or not, the free review is a learning tool.
