  description

  DemoAlias is a Chrome extension for sales demos, product walkthroughs, Loom
  recordings, and course screenshots — anywhere you need to record a real app
  without exposing real customer data, and where blur looks distracting.
  Click Replace once and every email, phone number, money amount, ID, token,
  company name, IP address, and credit card on the page is swapped for a
  consistent demo value. Sensitive values stay consistent across the session —
  the same real email always maps to the same demo email — so recordings look
  coherent end-to-end.
  Save a site once and the next visit auto-applies the mapping, including
  when you navigate inside SPAs (Notion, Linear, Gmail, etc).
  WHAT IT DETECTS
  • Email addresses
  • Phone numbers
  • Money amounts
  • IDs (cus_/sub_/acct_/etc Stripe-style prefixes)
  • API tokens (Stripe, GitHub-style)
  • Company names
  • IP addresses
  • Credit card numbers (Luhn-validated to avoid timestamp false positives)
  • Domains and URLs (opt-in — higher false-positive rate)
  TWO OUTPUT STYLES
  • Realistic — themed pool of ~20 entries per type ([email protected],
    $12,480.00, etc).
  • Masked — visually obvious placeholders (••••1@••••••.com, $••,••0.00).
  PRIVACY BY DESIGN
  • Runs entirely in your browser. Zero network calls.
  • Real sensitive values are never stored — only non-reversible hashes.
  • No analytics, no telemetry, no third-party scripts.
  KEYBOARD SHORTCUTS
  • Alt+Shift+D — open popup
  • Alt+Shift+R — toggle replace / restore on the current page
  INTERACT FROM THE PAGE
  Click a highlighted value on the page to exclude it from replacement
  (useful when a detector finds a false positive). Click again to re-include.
  Selections sync between page and popup.
  PER-SITE PERSISTENCE
  The Save button persists the current mapping and exclusions for the site so
  the next time you load it — even after a browser restart — DemoAlias
  applies it automatically. Forget reverses Save in one click.
  OPEN SOURCE
  Source code, issue tracker, and roadmap: https://github.com/flreey/demoalias

  Record SaaS demos without exposing real customer data — no blur, no manual edits.
  DemoAlias is a free, open-source Chrome extension that replaces every email,
  phone number, money amount, ID, token, IP, and credit card on the page with
  a consistent demo-safe value. One click. Zero network calls. Nothing leaves
  your browser.
  Built for sales engineers, product managers, course creators, support
  engineers, and anyone who records or screenshots real software for an
  audience that shouldn't see real customer data.
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  WHY DEMOALIAS INSTEAD OF BLUR
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Blur is ugly. It hides the layout your viewer is trying to learn. Manual
  edits don't scale across 12 dashboard rows. Screenshot tools forget what
  you blurred last time and you redo it for every recording.
  DemoAlias replaces values in place — same DOM, same layout, same vibe —
  and the same real value always maps to the same demo value across the
  session. Your recording looks coherent, your customers stay private.
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  HOW IT WORKS
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  1. Open any live SaaS page (Stripe, Linear, Notion, Salesforce, your
     own admin panel — anything).
  2. Press Alt+Shift+R, or click Replace in the popup.
  3. Every sensitive value is swapped in place. Record clean.
  Click Save on a site you record from regularly, and DemoAlias auto-applies
  on the next visit — including SPA route changes inside Notion, Linear,
  Gmail, and similar apps.
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  WHAT IT DETECTS
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  10 detector types out of the box:
  • Email addresses (modern TLDs included — .work, .chat, .me, .xyz)
  • Phone numbers (US, international, parenthesized, dashed)
  • Money amounts (USD, EUR, GBP, plus generic currency formats)
  • IDs with Stripe-style prefixes (cus_, sub_, acct_, in_, ch_, evt_)
  • API tokens (sk_live_, pk_live_, whsec_, ghp_ GitHub PATs)
  • Company names (against a curated dictionary)
  • IPv4 addresses
  • Credit card numbers (Luhn-validated to avoid timestamp false positives)
  • Domain names (opt-in)
  • Full URLs (opt-in)
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  TWO OUTPUT STYLES
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  Realistic — themed pool of ~20 believable values per type.
    [email protected] → [email protected]
    $128,400.00 → $42,180.00
  Masked — visually obvious placeholders for when "this is fake" matters.
    [email protected] → ••••1@••••••.com
    $128,400.00 → $••,••0.00
  Switch in the popup. Use Realistic for sales demos, Masked for compliance
  screenshots.
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  WHO USES IT
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  • Sales engineers recording Loom walkthroughs for prospects
  • Product managers presenting roadmap demos to leadership
  • Course creators recording SaaS tutorials for students
  • Support engineers sharing screenshots with vendors
  • Conference speakers showing real workflows on stage
  • Founders pitching investors over Zoom
  • DevRel and educators writing blog posts with screenshots
  • Anyone filing a bug report that includes a screenshot of a real account
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  PRIVACY BY DESIGN — NOT BY PROMISE
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  • Runs entirely in your browser. Zero fetch / XHR / WebSocket calls. Ever.
  • Real sensitive values are never stored. The Save mapping is keyed by
    a non-reversible hash, so even chrome.storage.local never holds the
    real value.
  • No analytics, no telemetry, no crash reporting, no fingerprinting.
  • No remote code loading. All logic ships in the extension package.
  • MIT licensed. Audit the source yourself.
  ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
  KEYBOARD-FIRST

  • Alt+Shift+D — open the popup
  • Alt+Shift+R — toggle replace / restore on the current page
  Customize these in chrome://extensions/shortcuts.
