PageBunker is a Chrome, Edge, and Firefox extension that saves the article you are reading to your own device. No account, no server.
Saving keeps the title, author, publish date, and the article body (paragraphs, headings, lists, quotes, code, tables) and leaves out ads, menus, and comments. If the body cannot be extracted, the link is saved instead. Saved articles open without a network connection and still open after the original page is gone. Images are not loaded by default, so the original site is not contacted when you read.
The library has To read, Read, Archive, and Trash (Trash empties after 30 days), with sorting, tags, and multi-select. Search covers titles, sites, tags, and the full article text in English and Korean.
Every library change writes a backup file to Downloads/PageBunker/pagebunker-latest.json, plus a dated file at most once a day (latest 7 kept). The browser keeps 3 recent copies. Removing the extension leaves the Downloads files in place, and you can restore from one of them. This is a file on the same machine, not a cloud backup.
You can import a Pocket CSV, Pocket legacy HTML, Instapaper CSV, or a bookmarks HTML file with a preview and an undo; imported rows arrive as links until you open the page and save. Export is one HTML file or one Markdown file per article.
