i built a suspicious login log analyzer

recently i’ve been trying to make smaller things that actually do something real.

so i built a suspicious login log analyzer.

in simple terms, it’s a small web app where you can paste login records from a system, and it helps point out patterns that might be suspicious. for example, if the same address keeps failing to log in again and again, or if someone is trying common account names like admin or root, or if there’s a sudden burst of login attempts late at night, the app will flag that.

what i like about it is that it takes something that normally looks messy and hard to read, and turns it into something much easier to understand. instead of staring at a wall of technical text, you get a clearer picture of what might be going on.

i also wanted to keep it simple and honest. not something that pretends to be smarter than it is, but something useful. something that looks at patterns, explains why they matter, and makes the logs feel less overwhelming.

it’s a small project, but i’m proud of it because it feels practical. it feels like the kind of thing that takes a confusing problem and makes it a little more human.
