SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Perform 12-Factor App compliance analysis on any codebase. Use when evaluating application architecture, auditing SaaS applications, or reviewing cloud-native applications against the original 12-Factor methodology.

Core Features & Use Cases

  • Factor-by-factor checks: codebase, dependencies, config, backing services, build/run, processes, port binding, concurrency
  • Practical guidance and search patterns for each factor

Quick Start

Provide a root path to a codebase and run the analysis to generate an immediate report.

FAQPage Schema
How do I audit a codebase for 12-factor app compliance?

12-factor app compliance audits assess your codebase against the 12-factor methodology to ensure cloud-native readiness. The analysis scans factors like codebase management, dependencies, configuration handling, and backing services, then generates a structured report identifying gaps and remediation guidance for your architecture.

What is the 12-factor app methodology and why does it matter for cloud-native applications?

The 12-factor methodology is a set of best practices for building scalable, maintainable SaaS applications. It covers codebase organization, dependency declaration, configuration management, and process design. Following these factors ensures your application can deploy reliably across cloud environments and scale efficiently.

Can I check my application for 12-factor antipatterns during architecture review?

Yes. During architecture audits and SaaS reviews, you can scan your codebase to detect antipatterns across factors like port binding, concurrency models, and backing service configuration. The analysis flags violations and provides practical search patterns and remediation steps for each factor.

What does a 12-factor compliance report include?

The report assesses factor-by-factor compliance across codebase structure, dependencies, configuration, backing services, build and run separation, stateless processes, and port binding. It generates structured findings with detection results and practical guidance for addressing each compliance gap in your code and configuration.

Do I need special tools or dependencies to run a 12-factor audit?

No special dependencies are required. Provide your codebase root path and run the analysis. The audit scans your code, configuration files, and dependency declarations against the 12-factor factors, then generates an immediate compliance report with no additional setup.

When should I perform a 12-factor compliance check?

Run compliance checks during cloud-native deployment evaluations, SaaS application reviews, and architecture audits. It's particularly valuable when migrating to cloud platforms, refactoring monolithic applications, or validating that existing codebases follow distributed systems best practices.
