Spec-Driven-Development vs AudioEye

Spec-Driven-Development focuses on preventing AI tool contradictions by generating three shared specification files (requirements.md, design.md, tasks.md) with traceable requirement IDs and acceptance criteria. It includes a conversational 4-question interview for greenfield projects and a retrofit mode for existing codebases. The skill auto-creates universal instruction blocks embedded into config files for Claude Code (CLAUDE.md), Cursor (.cursorrules), Windsurf (.windsurfrules), GitHub Copilot (.github/copilot-instructions.md), and Aider (.aider.conf.yml). This ensures all AI coding tools share the same context. In contrast, AudioEye provides automated accessibility scanning, AI-powered issue detection and remediation, screen reader simulation, color contrast analysis, and keyboard navigation testing. It offers human expert audits, VPAT/ACR documentation, continuous monitoring, and accessibility overlays. AudioEye integrates with CMS platforms like WordPress, Drupal, Shopify, and Salesforce, and includes legal support for ADA/WCAG compliance. The core difference: Spec-Driven-Development is a developer tool to improve AI code consistency; AudioEye is a compliance tool to fix accessibility issues.

Spec-Driven-Development is free and open-source under the MIT license, with no paid tiers. Users only need a Claude subscription, but the skill itself costs nothing. AudioEye uses a paid, custom pricing model typical of enterprise SaaS platforms. It likely charges based on website size, number of pages, and required support level. There is no free tier mentioned. For a team already using Claude Code, Cursor, Windsurf, Copilot, or Aider, Spec-Driven-Development adds zero cost. However, AudioEye's pricing can be substantial, often thousands per year for small sites and more for large enterprises. The choice is clear: free vs. proprietary paid.
