Side Link Preview

Side Link Preview turns Chrome's Side Panel into a split-view reading surface. Qualifying links — same-tab clicks and new-tab links by default — open on the right, side-by-side with the page you came from. No tab explosion, no context switch, no extra browser. Independent open-source project; not affiliated with any browser vendor. WHAT IT DOES • Click qualifying outgoing links → they open in Chrome's Side Panel • Follow links inside the panel — it refreshes in place without piling up tabs • Hold ⌘ / Ctrl / Shift / Alt while clicking to fall back to a real new tab KEY FEATURES • Mini browser in the panel: address bar, Back / Forward / Refresh, Open in main tab, per-site zoom • Auto-retry once on embed failures, then a diagnostic card with likely causes and technical details • Toolbar shortcut: "Don't use side panel on this site" (blacklist mode) — no Settings required • Per-domain blacklist or whitelist with **separate saved lists**, path-prefix rules and wildcards • Link scope: all qualifying links (default) or new-tab links only • Open trigger: left click (default) or middle click; optional hover preview with delay (independent of click mode) • Smart link filtering: downloads, login/checkout paths, IP addresses, mixed content, and more stay native • Right-click "Open link in Side Panel" and Alt+Shift+P to preview the current tab • Automatic light / dark theme; UI in nine languages (follows your browser on first install) • Works on many iframe-blocking sites via a tightly scoped Side-Panel-only response-header rule SECURITY & PRIVACY BY DEFAULT • 125+ sensitive hosts excluded from script injection: sign-in, SSO, banking, webmail, video calls, streaming, cloud consoles, crypto, government TLDs, and more (see manifest) • Also skips IP addresses, localhost, and corporate `.local` / `.internal` / `.corp` domains • Checkout, payment, and OAuth paths are never routed through the panel • No analytics, no tracking, no telemetry, no remote config — settings sync via Chrome only • Header rewriting applies only to iframe requests initiated by this extension's Side Panel • Full policy: https://github.com/ds009/side-link-preview/blob/main/PRIVACY.md WHO IT'S FOR • Anyone who wants split-view, side-by-side reading on stock Chrome • Researchers, students and lawyers who read a long article while opening many sub-links • Engineers who follow link chains across docs, pull requests and Q&A sites without piling up tabs • Readers who prefer their original page to stay visible while skimming a referenced source REQUIREMENTS Chrome 119 or later (Side Panel API). Also works on Microsoft Edge 119+. OPEN SOURCE MIT-licensed.
