Online Extension Checker

The Online Extension Checker analyzes a target extension’s manifest.json, declared permissions, and host patterns to determine readiness for release and compliance with browser policies. It conceptually treats the manifest as a contract between the extension and the browser, verifying that requested permissions align with claimed functionality and that host_matches are appropriately scoped. This yields a deterministic risk assessment and an audit-ready report. Users such as QA engineers, security auditors, and developers gain clarity on permission scopes, deprecated APIs, and potential policy violations. Unique value lies in its focused, repeatable checks that support both quality assurance and SEO-related risk analysis, without requiring a full runtime test.
Core features include manifest parsing, permission-risk scoring, host-pattern validation, and a browser-compatibility signal. The tool outputs a structured result with a summary, detailed findings, and remediation guidance. Typical use cases involve pre-release validation, security reviews for extension-based site enhancements, and compliance checks during SEO audits where extension behavior could impact site integrity or user experience. The approach emphasizes transparency, reproducibility, and exportable artifacts for stakeholder review.
This tool benefits product teams, security teams, and developers who need objective, documentable evidence of extension readiness. It helps reduce release risk, improve stakeholder confidence, and support governance processes by providing clear, actionable insights and standardized reports.
