Beyond dedicated apps, what are legitimate free sources for reading digital comic books?

Beyond dedicated apps, legitimate free sources for digital comics include your local public library (via apps like Libby or Hoopla with a library card), publishers' websites (some offer free first issues, previews, or promotional comics), and webcomic platforms such as GlobalComix which hosts independent creators. Additionally, Project Gutenberg offers public domain comics and graphic novels. Many independent creators also share free short stories, webcomics, or previews directly on their personal websites or platforms like Patreon (often with a free tier).
