Every link you share is scanned before it goes live
Flyn checks every destination against Google Safe Browsing and a content blocklist the moment you create or edit a link, then rescans on a schedule. Anything that turns malicious is disabled automatically, so a bad destination never rides on your short link.

Link safety scanning is Flyn's built-in defense against pointing a short link at something harmful. Before a link goes live, its destination is checked against Google Safe Browsing (Google's database of malware, phishing, and unwanted-software sites) and a content blocklist. Passing links go live as normal. Flyn then rescans destinations on a schedule, because a page that was clean on Monday can be compromised by Friday. If a destination is later flagged, the link is disabled automatically and serves a gone response instead of forwarding anyone to danger. It runs on every plan, Free and Pro, with nothing to switch on.
How it works
Up and running in minutes
Scanned automatically on create and edit
The moment you shorten a URL or change a link's destination, Flyn checks that destination against Google Safe Browsing and its content blocklist. Clean links publish immediately. A destination that comes back flagged is refused with a clear reason, so a known-bad page never becomes a live short link in the first place.
Rescanned on a schedule
A destination that was safe when you created it can be hacked, hijacked, or repurposed later. Flyn periodically rescans the URLs it serves, so protection does not stop at creation time. Links are re-checked in the background without you lifting a finger.
Unsafe links are disabled automatically
If a rescan flags a destination, Flyn disables that link and serves a gone response (HTTP 410) instead of forwarding the visitor. The redirect stops the instant a threat is confirmed, which contains the damage before it reaches your recipients or your domain's reputation.
Report abuse or hit the kill switch
Anyone can flag a suspicious link through the abuse-report path, and Flyn keeps a kill switch to take a link offline fast. Reported and killed links are served the same gone response, so a problem link is neutralized without waiting on the next scheduled scan.
Why it matters
What you get
Recipients are protected from malware and phishing
Every destination is screened against Google's Safe Browsing lists for malware, social engineering, and unwanted software. The people who click your links are shielded from the most common web threats before a single redirect fires.
Your domain's reputation stays clean
Short links that forward to malicious pages get whole domains blocklisted by browsers and mailbox providers, which breaks every link you have ever shared. Scanning and auto-disabling keep bad destinations off your links, protecting deliverability and trust.
Protection that does not expire at creation
A destination can go bad long after you shorten it. Scheduled rescans re-check the URLs Flyn serves, so a page that gets compromised next month is caught and the link is pulled, not left forwarding traffic into a trap.
Bad links are stopped, not just flagged
When a threat is confirmed, Flyn does not merely warn you. The link is disabled and serves a gone response, so the redirect stops immediately and no one downstream is sent to the harmful page.
An abuse path and a kill switch
A reporting path lets anyone flag a suspicious link, and a kill switch lets a problem link be taken offline fast. Both routes serve the same gone response, so a flagged link is contained quickly rather than waiting on the next scan.
On by default, on every plan
There is no setting to enable and no add-on to buy. Safety scanning runs on both Free and Pro accounts, on every link, from the first one you create. Clean links stay fast, threats get blocked.

Frequently asked questions
What does Flyn check each destination against?
Two layers. First, Google Safe Browsing, Google's database of sites known for malware, social engineering (phishing), and unwanted software. Second, a content blocklist maintained by Flyn. A destination has to clear both to go live, and both are re-applied when links are rescanned later.
When does scanning happen?
Automatically on create and edit, so a flagged destination is refused before the link ever publishes, and then periodically on a schedule for links that are already live. That second pass matters because a destination that was safe when you shortened it can be compromised afterward.
What happens if one of my links is found unsafe?
Flyn disables the link and serves a gone response (HTTP 410) instead of forwarding the visitor. The redirect stops the moment a threat is confirmed, so no one who clicks is sent to the harmful page, and your domain is not associated with the bad destination.
Can I report a link that looks malicious?
Yes. There is an abuse-report path for flagging suspicious links, plus a kill switch to take a link offline quickly. Both serve the same gone response, so a reported link is neutralized without waiting for the next scheduled rescan.
Is link safety scanning a paid feature?
No. It runs on both the Free and Pro plans, on every link, with nothing to switch on. Scanning protects everyone who shares links through Flyn and keeps the shortener itself clean, which is in every user's interest.
Will scanning slow down my links or block legitimate destinations?
No. Clean links publish and redirect at full speed, and the checks target known-bad destinations rather than guessing. If a legitimate destination is ever affected, the abuse path and kill switch are matched by the create-time reason message, which tells you exactly why a destination was refused.
