Find dead links, missing #anchors, and bot-wall false positives. Scans run locally in your browser. Privacy-first broken link checks for modern sites. BrokenBuster helps SEO teams, documentation teams, and developers find broken links on modern pages without sending URLs to a server. Scan the current page from your browser, catch dead URLs and missing #anchor targets, separate real failures from bot-protection false positives, and export a clean report when you are done. BrokenBuster is built for real-world page QA, not just basic 404 checks. It audits links and assets directly on the page you are reviewing, keeps progress visible in the side panel, and gives actionable status labels so your team can decide what to fix now versus what to re-verify. Why teams use BrokenBuster Missing #anchor detection: Find links like page.html#pricing where the page loads but the target anchor was removed or renamed. Bot-wall false-positive handling: Identify Cloudflare, Akamai, and Imperva-style protection responses so blocked checks are not confused with confirmed broken links. Local-first privacy: Link checks run from your browser. BrokenBuster does not send page URLs, staging links, or scan results to a backend. Side panel review: Keep scan results visible while you inspect the page and focus individual links. CSV and HTML export: Save a local report for QA notes, SEO audits, or client handoff. Page-aware result context: Understand where each link came from (navigation, main content, sidebar, footer) to prioritize fixes faster. Streaming scan progress: Results appear as checks complete so you can start triaging before the full scan finishes. Quick-start scan presets: Use SEO Audit, Docs Audit, or Staging QA presets to reduce setup time and focus on the right link scope. Per-link fix workflow: Open one result at a time, inspect reason details, copy replacements, and review archive snapshots. Local cache and ignore controls: Speed up repeat scans and suppress known false positives with exact/domain/regex rules. Keyboard-accessible workflow: Navigate and review results quickly without leaving your current page context. What BrokenBuster checks Standard page links (a[href]) Image assets (img[src]) Script assets (script[src]) Stylesheet links (link[rel="stylesheet"]) Status meanings you can trust Broken: The URL failed, timed out, or an expected #anchor target is missing. Redirect: The URL resolves, but forwards users to another destination. Bot blocked: A protection layer likely blocked the request, so it is not treated as a confirmed broken link. Slow: The URL responded, but performance was slower than the expected threshold. Best for Technical SEO audits: Check page-level link health, redirects, dead URLs, and assets. Documentation QA: Validate internal documentation links and in-page anchors before release. Private staging checks: Audit links on staging, preview, and internal pages without a hosted scanner. BrokenBuster is intentionally local-first. There are no accounts, no analytics, no backend link checks, and no hosted reports. Changelog (v1.5.0) Improved bot-wall classification to reduce false positives on healthy CDN-backed responses. Improved fragment (#anchor) validation for quoted, unquoted, encoded, and HTML-entity cases. Added clearer scan-state handling so restored results are labeled as Last scan. Improved report export table consistency (status/code columns aligned with data). Improved reviewer and security posture by removing unnecessary request-modification permission usage. Improved reliability by removing browser API dependency patterns that can cause compatibility edge cases. Continued UI onboarding improvements from Week 2 work: Preset-driven quick start (SEO, Docs, Staging) Inline status explanation helper Clearer side panel CTA
