I’m building CTF Replay Lab, an interactive browser-based workspace that turns CTF artifacts into guided investigations instead of just giving players a terminal and expecting them to figure everything out alone.
The idea is simple: beginners often get stuck because they don’t know what to look at next or why a certain command matters. So this project helps users analyze files, inspect metadata, extract hidden clues, and move through replayable checkpoints while learning the reasoning behind each step.
It supports common CTF workflows like hashing, entropy checks, string extraction, hex inspection, Base64/ROT/Caesar/XOR-style decoding, and evidence tracking — all in one place. I’m also making it privacy-friendly by keeping the analysis local in the browser whenever possible.
My goal is to make CTFs feel less intimidating, more educational, and much more accessible for newcomers.
