LinkSentinel
Paste any link. Traces redirects, grades security headers, inventories cookies and third-party scripts, and explains the risk in plain English.
Check beforeyou trust.
Practical security tools for links, repositories, and files. Paste, scan, read the report — plain English, no account, no upload.
Three tools, one habit.
Each tool answers one question you should ask before clicking, cloning, or opening: what am I actually looking at?
RepoSentinel
Point it at a public GitHub repository. Reads metadata, community files, dependency manifests, and risk indicators — then reports what it found, read-only.
FileSentinel
Drop a file. Hashes are computed in your browser — nothing is uploaded. Verify an expected checksum, inspect metadata, and flag suspicious traits.
Findings, not verdicts.
Plain English over jargon
Every finding says what was checked, why it matters, and what to do about it. No acronym soup without an explanation attached.
Honest language
No tool here will ever call something "safe" or "virus-free". The strongest claim you will see is "no obvious issues detected by these checks" — because that is all a scan can honestly say.
Nothing leaves your machine without saying so
FileSentinel hashes locally in the browser. RepoSentinel only reads public GitHub data. Any future network lookup will ask first.
