I built SubSnacker to address a simple personal pain point: I wanted to download and back up my favorite Substack newsletters (especially those I paid for) without any hassle.
SubSnacker makes it easy to convert posts to HTML and download them in bulk. If you want to keep a local archive of the writing you love, give it a try.
