Everything you need,
nothing you don't.
From simple link shortening to enterprise analytics — C3.lt scales with you.
Smart Short Links
Branded short links with custom slugs and AI harm-classification on every URL. Add expiration dates and click limits on Pro.
Geo & Device Routing
Automatically route iPhone users to the App Store, Android users to Play Store, and visitors from specific countries to localized pages.
A/B Testing
Split one short link across multiple destinations, weighted-randomly per click. See which variant converts — then ship the winner.
Branded Interstitials
A full-page splash with your headline, logo, and a short countdown before the redirect. Turn a bare link into a branded moment.
Password-Protected Links
Gate sensitive short links and bio pages behind a password. PBKDF2 hashing with timing-safe comparison.
Bio Pages
Link-in-bio pages with 7 themes, sections to group links, scheduled activation/expiry, and per-link analytics.
Featured Hero Cards
Pin a launch as a larger hero card above the rest of the link grid. OG-image thumbnails auto-fetched from the destination.
Embedded Media
YouTube, Vimeo, Spotify, and SoundCloud links render as inline players on your bio page — not just buttons.
Tip Jar Cards
Ko-fi, Buy Me a Coffee, Stripe Payment Links, PayPal.me, Patreon, and more — render as accent-bordered tip cards. Money goes straight to you.
Custom CSS & JS
Full design control on Business. Override any styling token with live preview, and run sandboxed JS (GTM, analytics tags) in a null-origin iframe.
Theme Marketplace
Publish a bio-page theme for others to use, or apply a community theme to your own page in one click. Business plan.
Email Subscribers
Visitors sign up via the bio-page form; one-click unsubscribe; CSV export. Pro/Business only.
Broadcast Emails
Send a one-shot email to your entire subscriber list from the dashboard. HMAC-signed unsubscribe per recipient.
Retargeting Pixels
Drop Meta, Google Ads, and TikTok pixels on any link. Build retargeting audiences from clicks without owning the destination.
Conversion Goals
Define goals, drop a 1×1 pixel on your thank-you page, and see conversion rate per link. Best-effort cookie attribution.
Analytics Dashboard
Clicks by country, device, browser, and referrer. Per-link drill-down with sparklines. Up to 365 days retention.
AI Insights
Weekly AI-generated readouts of your click activity — what spiked, where traffic came from, what to do next. Pro & Business.
Link Health Checks
A weekly crawl pings every destination and flags dead, slow, or unexpectedly-redirecting links in your dashboard. Pro & Business.
CSV Export & Webhooks
Export any analytics view as CSV on Pro. On Business, pipe live click events into your own systems via HMAC-signed outbound webhooks.
Two-Factor Auth
TOTP via any authenticator app (Google Authenticator, 1Password, Authy). Backup codes for account recovery.
Abuse Protection
AI URL classification, public report flow, and admin review queue. Bad actors suspended fast — your reputation stays clean.
QR Codes
Customizable QR codes for any short link. Choose colors, rounded corners, download as SVG for print. Up to 50 on Pro.

Full REST surface with SHA-256 hashed Bearer tokens. Create links, query analytics, manage profiles programmatically.
