Otto Stack

Otto Stack is the entry point to Otto. It assesses your current tech stack against a curated, versioned registry of approved technologies, then provides specific recommendations to modernize and standardize your projects.

What Otto Stack Does

• Stack Assessment — Scans your project's dependencies, frameworks, and configurations. Identifies outdated versions, deprecated libraries, and non-standard patterns.
• Scaffolding — Generates new projects using approved stacks with best-practice configurations already in place.
• Conversion — Guides migration from legacy or non-approved stacks to approved alternatives, including CMS-to-code conversions.
• Continuous Modernization — Monitors your stack over time and alerts you when dependencies need updating or new best practices emerge.

The Stack Registry

At the core of Otto Stack is a curated registry of approved technologies. This is not just a list of frameworks — it includes specific version ranges, configuration standards, and validation criteria. The registry is continuously updated, and old vulnerable stacks are removed.

Categories in the registry include frontend frameworks, backend frameworks, databases, ORMs, authentication libraries, CSS approaches, testing frameworks, CI/CD tools, and more.

How an Assessment Works

1. Otto reads your project's configuration files (package.json, Dockerfile, CI configs, etc.)
2. Each dependency and configuration is checked against the registry
3. A scorecard is generated showing what is compliant, what needs updating, and what should be replaced
4. Specific remediation steps are provided for each finding

Free Scorecard

Every project gets a free stack scorecard — no subscription required. The scorecard shows your overall stack health and highlights the top issues. Full remediation details and ongoing monitoring require an Otto Stack subscription.
