FormSpackle

One-click form autofill for developers & QA engineers

What it does

FormSpackle is a Firefox extension that fills any form instantly with one click — built for developers and QA engineers tired of typing the same test data repeatedly. It smartly detects field types, supports dropdowns, checkboxes, date pickers, and modern UI libraries. Features include saved profiles, multi-form support, fill-empty-only mode, and a built-in field inspector. 100% local — no tracking, no data leaves your browser.
