Algorithm Visualizer
visualisation
Write or paste an algorithm and watch it animate against its own data structure, with the code and the picture side by side. Open source, and you can add your own.
We never managed to photograph this one while it still worked, so there is no picture of it here — only the record that it was made.
algorithm-visualizer.org did not answer the last 6 times we looked, most recently on 11 September 2026. The listing stays up, and so does our screenshot: the thing existed, somebody made it, and this is the record of it.
The address has not changed, so it is worth a try — a site that was down for a week is not always gone. If it works for you, say so underneath and we will stop warning people off it.
how this can help
Someone has drawn the thing that is hard to picture. Good for a concept you can state but cannot see.
what it covers
Filed under Computer Science. Algorithms and machines, running slowly enough to watch.
who put it here

On the desk since 7 September 2026. Staffroom has sent at least 1 person through to it.

what readers say
No reviews yet. Nobody vouched for this one and nobody warned you off it — you would be the first.
Anyone can add a site here and nobody approves it first, so this is the only thing that separates a good link from a bad one. There are no accounts: one browser leaves one review, and clearing your cookies makes you a new reader.
something wrong with this listing?
A report does not hide anything. It puts the listing in front of a person who can take it down, and until they do it stays exactly where it is.
