SeqAns runs in your browser, no calls to the server

Sequences are rendered in the browser using a JavaScript library called d3.js (v3). SeqAns uses FileSaver.js to save to file. SeqAns also uses local storage to preserve editings.

Running from sources

You can also run SeqAns directly from sources, just open the root index.html file in the browser of your choice, no server needed.
