About
Data Harvester collects links, headings, images, and picked elements on a normal http(s) page. Chrome://, the Web Store, and other restricted pages are skipped. Free tools stay in this browser — no ExtHub account.
Pick elements on the page or scan with recipes (Links, Headings, Images). Preview the last items in the popup, copy TSV, or export JSON/CSV locally. Pause everywhere or turn harvesting off for this host. Last 30 harvests in the popup (hostname, item count, recipes — not harvested text). Up to 20 hosts and 80 items locally. Harvested text, emails, hrefs, and page HTML are never uploaded.
Pro syncs site recipes and the harvest log to ExtHub (hostname, presets, optional extra selector, item counts — not harvested text, emails, hrefs, or HTML). Extra recipes: Tables, Emails, Meta, plus a custom CSS selector. JSON export/import of recipes and the log, and copy the same recipe to www and the apex host. Higher caps (50 hosts / 80 log rows / 400 items). Search and CSV/JSON export are on ExtHub. Unsigned installs still send a compact connectivity ping.
