Best Form Auto Fill Extensions for Chrome (2026) – Complete Comparison

The Donkey Directories Chrome extension is purpose built for founders who need to scale their presence across 295+ curated launch directories. Unlike a generic form auto filler extension, this tool understands the specific architecture of sites like AppSumo and BetaList. It allows you to auto scrape your product info (name, tagline, description, and socials) once and deploy it across hundreds of forms. This is a game changer for an independent product launch where time is your most valuable asset. Using this tool ensures you do not get bogged down by the manual labor of a one way directory submission strategy. You can track every detail in a centralized submissions tracker, making it much more advanced than a simple client track system.

Fake Filler is the go to google chrome extensions for developers who need to fill form online with dummy data. Instead of providing real product information, it generates random names, emails, and phone numbers to test form logic. It is particularly useful if you are building an app with a complex form submission api and need to verify how your backend handles diverse inputs. While it can handle ajax form submission testing, it lacks the persistent data storage needed for a product launch campaign. It is a powerful tool for QA but not for marketing.

For individuals navigating the job market, jobfill.ai acts as a personal submissions tracker. It uses AI to parse your resume and map it to job application fields automatically. While it shares some DNA with an auto form filler extension, its logic is tuned for HR software rather than the ls only directories or yext directories used by marketers. If you are a startup founder looking for help for your team via hubspot for startups or managing a circle startup, this tool is less relevant than direct submission fillers but invaluable for career growth.

QuickForm is a versatile form auto filler extension that caters to a broad audience. It allows users to create multiple profiles, which is helpful if you are managing different personas or business entities. It works well on a variety of sites, including those for a name change form or general user registrations. While it doesn't have the specific directory maps of Donkey Directories, its flexibility makes it a solid choice for everyday productivity tasks across the web.

AutoFill Forms is one of the more established google chrome extensions in the store. It has a high install count and a reputation for reliability. It focuses on the basics: storing form data locally and auto-detecting fields when you land on a page. This is particularly appealing for privacy-focused users who do not want their data synced to a cloud service. It is a straightforward auto form filler extension that gets the job done without extra fluff.

When selecting an auto form filler extension, consider the 'Implementation Time.' A solo founder at a discern startup needs something that works out of the box. If you are comparing two directories using a unix command to compare two directories, you probably value technical control and precision. However, for a standard circle startup launch, ease of use is king. Check if the tool offers a submissions tracker to stay organized. Budget is also a factor. Subscription models are common, but one time payments (like those offered by Donkey Directories) often provide better ROI for a one-off product launch compared to monthly fees.
