# Software Planning Comparisons

> Use evidence-backed comparisons to choose between planning frameworks and document formats without rankings or unsupported quality claims.

These comparisons answer a concrete choice using official repositories or documentation captured on July 18, 2026. They compare artifact models and workflows, not popularity or a universal “best” method.

<CardGroup cols={2}>
  <Card title="Superpowers vs GSD" icon="code-compare" href="/compare/superpowers-vs-gsd">Choose between a defined design-to-execution method and a durable project-state system.</Card>
  <Card title="GitHub Spec Kit vs Kiro Specs" icon="code-compare" href="/compare/github-spec-kit-vs-kiro-specs">Choose between an open feature directory and an integrated three-file spec workflow.</Card>
  <Card title="ADR vs RFC vs technical specification" icon="file-circle-question" href="/compare/adr-vs-rfc-vs-technical-specification">Choose the document that matches the decision, discussion, or maintained contract.</Card>
  <Card title="PRD vs technical specification vs implementation plan" icon="layer-group" href="/compare/prd-vs-technical-specification-vs-implementation-plan">Use this supporting guide to separate product intent, maintained technical design, and the current execution sequence.</Card>
</CardGroup>

Each page states its sources, observed differences, and the decision each format supports. A source change can invalidate a comparison, so the capture date is part of the evidence.
