About
FillFast fills the open form with ONE believable record in a single keystroke — name, email, phone, address, and salutation all derived from the same person, so nothing contradicts. Built for the people who fill the same form fifty times a day: implementers, QA engineers, demo builders, and sales ops. Great for CRM forms (Salesforce, Dynamics, HubSpot and the like), and works on ordinary web forms too. WHY IT'S DIFFERENT • One coherent record — name → email → salutation → phone → address all derive from one person. Never a required field left blank, never a value that contradicts another. • Drives the controls your app actually uses — dropdowns, comboboxes, and date pickers pick from the form's real options. It uses native setters + input/change events, so the page's own Save passes cleanly (no "looks filled but won't submit"). • On-device. Records are generated locally, in memory, when you press the key. Filling a form makes no network request and nothing leaves the page. HOW IT WORKS 1. Open the form you want to test. 2. Press Alt+Shift+F (rebind it to whatever fits your hands) or click "Fill this form". 3. FillFast generates one internally-consistent fake record and types it into the fields. 4. Review and save — you're always in control of what gets submitted. PRIVACY No account, no analytics, no trackers, no remote code. FillFast never reads the data already in your CRM and never sends form data anywhere. The only thing it stores is your chosen keyboard shortcut. Full policy: https://fillfast.work/privacy PRICING FillFast is free. FillFast Pro ($9/mo, sold through Polar) supports development and will add AI-assisted features as they ship — today Free and Pro fill identically. Use FillFast only on systems you're authorised to enter test data into, with fake data, and always review a form before you save it.
