How to use ilync
Shorten links, share QR codes, publish a link-in-bio page, and check URLs for safety — no coding required. Everything here is easy to use.
Welcome
ilync turns a long web address into a short link you can paste anywhere. Visitors who open the short link are sent to the original page. You can also make QR codes, protect a link with a passcode, and publish one page that holds all your profiles.
Short links
Paste a URL, get a short one. Optional custom ending, expiry, and passcode.
QR & barcodes
Turn any text or URL into a scannable code you can download.
Link in bio
One public page at /@you with socials and buttons.
Safety check
Score any URL before you share or shorten it.
Create an account
You can shorten links without signing in. An account unlocks custom codes, passcodes, your dashboard, a bio page, custom domains, and higher limits.
- Open Account.
- Choose Google, or sign up with name, email, and password.
- Email/password accounts get a verification link. You can keep using ilync before you click it — the dashboard banner lets you resend.

Shorten a link
- Go to the home page and paste a long URL.
- Leave Auto selected unless you want a custom ending.
- Optionally pick how long the link should last: Never, 1 hour, 1 day, 7 days, or 30 days.
- Signed in? You can add a passcode so visitors must type it before the page opens.
- Submit. Copy the short link, open stats, or make a QR / barcode.
Links you create while signed out may appear in Recently shortened. Links you create while signed in stay off that list unless you choose to list them later.
Custom codes
A custom code is the ending you choose, like ilync.dev/launch. Sign in, switch to Custom URL, and type 3–32 letters or numbers. Some names are reserved (account, docs, and similar). If it’s taken, pick another.
Expiration
After the time you chose, the short link stops working and visitors see an expired page. Expired links leave the public feed automatically. Choose Never if it should stay live.
Passcodes
A passcode is a shared secret. Anyone with the URL sees a lock screen; only people who know the passcode are redirected. Set one when you shorten (signed in) or later from My links → Edit.
- At least 4 characters. It cannot be read back after you save.
- Wrong guesses are limited to 10 tries every 5 minutes per visitor.
- A correct entry is remembered for 30 minutes in that browser.
- Passcode links stay out of the public feed.
Edit, schedule, and notes
Open My links and tap Edit on a link you created while signed in.
Destination
Point the same short URL at a new page.
Schedule
Pick a go-live date. Until then, visitors see a scheduled page.
Note
A private reminder (up to 500 characters). Searchable. Visitors never see it.
List in feed
Show or hide the link in Recently shortened. Passcode links stay hidden.
Opening a short link
Most of the time the visitor is sent on immediately. Sometimes they see a message instead:
| Situation | What they see |
|---|---|
| Unknown code | Not found |
| Expired | This link has expired |
| Scheduled | This link is scheduled, with the go-live time |
| Passcode | A lock screen asking for the passcode |
| Destination turned risky | A warning, or a hard block if it’s severely dangerous |
Click stats
Every short link has a stats page at ilync.dev/yourcode/stats. Open it from the shorten result or from My links. Anyone with the stats URL can view it (except private API links).
You’ll see total clicks, a date range (24 hours to all time), a chart, breakdowns by device and country, and recent activity. Clicks are recorded without slowing the redirect.
My links
Signed-in links live on your account under My links. Search by code, destination, or note. Filter All / Active / Expired / Scheduled / Archived. Seven per page.
QR codes & barcodes
After you shorten, tap QR code or Barcode — or open the playground. Encode any URL or text, restyle colors, and download PNG or SVG.
| Format | Best for |
|---|---|
| QR | Any text or URL. Optional logo in the center. |
| Code 128 | Almost any ASCII — URLs, SKUs, serials. |
| Code 39 | Uppercase, digits, and - . $ / + % space. |
| EAN-13 | 12–13 digits (retail). |
| UPC-A | 11–12 digits (North America retail). |
| ITF-14 | Exactly 14 digits (shipping cartons). |
Guests can generate 21 codes per day. Sign in for unlimited.
Link in bio
Claim a public page at ilync.dev/@yourname. Edit it at /link (also linked from your account).
- Sign in and open Link in bio.
- Pick a username (3–24 letters, numbers, or underscores).
- Add a display name, optional tagline and photo.
- Add social profiles and custom buttons (up to 40 total). Reorder, enable, or remove each one.
- Turn Published on and Save. Changes are not live until you save.
Visit counts and per-button clicks show on the editor. The public page includes a theme toggle.
Custom domains
Serve short links on your own domain (for example links.example.com). Max 3 per account.
- Open Account → Custom Domains and add the domain.
- In your DNS, add a TXT record named
_ilync.yourdomain.comwith the token we show. - Wait for DNS to propagate, then click Verify.
Safety check
Paste any URL on /check (or the home Safety check section). You’ll get a 0–100 score and Safe / Suspicious / Dangerous, plus the checks that ran. If it’s Safe, you can shorten it from the report.
Every short link is screened when you create it and re-checked later. If a destination turns hostile, visitors may see a warning or the link may be disabled.
Guests: 14 checks per day. Results are advisory.
Your dashboard
/account is home base once you’re signed in.
| Area | What you can do |
|---|---|
| Profile | Photo (JPEG, PNG, WebP, GIF, max 4 MB), display name, verified badge. |
| Stats | Total links and how many are active. |
| My links | Search, filter, copy, stats, QR, edit, remove. |
| Link in bio | Shortcut to your public page editor. |
| Developer API | Create and revoke API keys (shown once — copy them). |
| Webhooks | Add endpoints that receive a click event whenever one of your links is opened. |
| Custom domains | Add, verify, remove. |
| Account | Sign out, change password, delete account. |
Install the app
Add ilync to your home screen from /install. On Android use Chrome’s Install button. On iPhone, open Safari → Share → Add to Home Screen. It isn’t a store app; updates arrive automatically.
Privacy & cookies
First-time visitors see a cookie banner. Accept or decline analytics cookies. Theme preference is stored on your device. Details live in the privacy policy and terms.
Delete your account
Account → Delete account. Type delete to confirm. This permanently removes your links from the dashboard, API keys, domains, bio page, and sign-in. It cannot be undone.
Feedback & support
For developers
Need HTTP endpoints, API keys, rate limits, and request examples? That’s the API reference — a Swagger-style explorer with Try it out.
Mint keys from Account → Developer API. The key starts with ilk_ and is shown once. Max 10 active keys. Don’t put keys in frontend code.
Want live events instead of polling? Add a webhook in Account → Webhooks. Pick a secret and ilync signs each payload with HMAC-SHA256 so you can verify it came from us before trusting it.
