SkipLink: Bypass ad-driven URL shorteners in one click

We've all been there: someone sends you adf.ly/xyz or earn4link.in/FLf1Y1,
and instead of a link you get a 5-second countdown, a popup asking you to
enable notifications, and a fake "Top 10 hospitals" article stuffed with ads —
before you reach the actual destination. That's the "shorten-and-earn"
business model: the person who made the link gets paid per click, and you
pay with your time.

SkipLink is a free, open-source tool that unwraps those links straight to
the real destination. No ads rendered, no timers, no fake pages.

What SkipLink does

Follows HTTP redirect chains and interstitial pages — a shortener pointing at another shortener keeps resolving.
Recognizes 1,537 shortener domains out of the box.
Decodes the usual tricks shortener pages use to hide the real link.
Detects the walls it can't climb — Google reCAPTCHA gates, safelink verification pages, and ad-farm "money pages" — and says so honestly, instead of guessing.
Ships as a one-click GUI, a CLI, and prebuilt executables for Windows + Linux.

How the engine works

The core is 100% Python standard library — zero dependencies.

1. Follow redirects manually

SkipLink sends one HTTP request with a real-browser User-Agent (cookies kept
across hops), but does not follow redirects automatically:

status, resp_headers, body = _fetch(opener, current, timeout, headers)
location = resp_headers.get("Location")
if status in {300, 301, 302, 303, 307, 308} and location:
    current = urljoin(current, _clean_url(location))

2. Extract the destination from interstitial pages

If the response is an HTML/JSON page instead of a redirect, the engine scans it
for the embedded destination. It handles, among others:

<meta http-equiv="refresh">
location.href = "..." / window.open("...")
var link = "..." / var url = "..."
atob("...") (base64) and unescape("...")
Skip/continue button anchors, data-* attributes, iframes
JSON APIs ({"destination": "..."})
A bare URL in a plain-text response

Every extracted candidate is filtered against a blocklist of ad/tracker CDNs
(doubleclick, taboola, adsterra, ...) so ads are never followed.

3. Stop at the real destination — or report the wall

The resolver stops when a page has no further redirect and no embedded link.
Then it classifies what that page is:

Captcha gate — Google reCAPTCHA / "human verification" → can't be auto-bypassed; only a real human in a real browser gets the link.
Safelink gate — wp-safelink "click to continue" locks.
Money page — a big filler article whose only purpose is showing ads, with no real off-site content links.

result["protection"] = detect_protection(text, current)
result["note"] = protection_note(result["protection"])

Optional: real-browser mode

Some hardened shorteners only reveal the destination when JavaScript runs.
SkipLink can drive a headless Chromium via Playwright, wait out countdowns,
and auto-click skip/continue/get-link buttons:

pip install -r requirements-browser.txt
playwright install chromium
skiplink -b "https://ouo.io/xyz"

Using it

CLI

python main.py "https://adf.ly/AbCdEf"          # one link
python main.py -f links.txt                     # a file of links
python main.py -j url1 url2                     # JSON output for scripting
python main.py -b "https://ouo.io/xyz"          # browser mode

As a library

from skiplink import resolve

result = resolve("https://adf.ly/AbCdEf")
print(result["final"])   # the destination URL
if result["note"]:
    print("NOTE:", result["note"])  # e.g. "Captcha-gated ..."

GUI

python gui.py   # or double-click the prebuilt app

Paste a link, press Enter, and the chain is resolved in seconds.
