I'm Tejus Bhasin, and I built Sus or Bus after my school was hacked over the summer. A teacher clicked a malicious link, which gave a bad actor access to that teacher's school email. From the teacher's account, the hacker emailed every student in the school, demanding money for a product that didn's exist. Students lost real money, and I felt deeply troubled by this. Sus or Bus exists to stop scams like this before they start, by checking the links you click, the emails you receive, and the sites you browse.
This project is open sourced - read the code on GitHubSus or Bus is a free web-safety analyzer. Paste in a link, an email, code, a document, or any text, and it looks for scams, phishing, trackers, and other sketchy behavior — then gives you one honest verdict: BUS (looks legit) or SUS (proceed with caution). No account needed, and every report works in plain language — with a nerd mode for the technical version of every finding.
A link, an email, HTML, code, plain text — or upload a document. The right mode is picked automatically.
Fresh scans take a few seconds. Links someone checked in the last week come back instantly from the shared cache.
BUS or SUS at a glance — then open the full report for the score, every finding, and safer alternatives.
Optional: install the extension so every link you click gets checked before the page even loads.
No red flags found. Safe to use — but keep your wits about you when logging in or paying anywhere.
Red flags found. Stop and reconsider — or jump to one of the suggested safer alternatives on the report.
Every report carries a 0–100 safety score — the higher, the safer — plus findings marked good, warning, or bad. Green flags are the reassuring parts; red flags are the reasons a site earned its SUS. Flip on nerd mode in settings to see the technical version of each one.
Sus or Bus started as a small tool to answer one question friends kept asking: “is this link safe?” It grew into a full safety engine — this website, a Chrome and Safari extension, and an iOS app — all built by a student developer, in the open. The whole project is open source under MIT, so anyone can read exactly how a verdict gets made.
