Autofilly solves a mundane but constant problem in web development: populating forms with placeholder data just to see how a layout behaves or to push a test case through. Rather than inventing fake names and addresses by hand, you click the extension button and it writes data into the form inputs on the current page. Out of the box it uses JavaScript-generated random values, which is instant, offline, and good enough for checking that fields render and submit.
If you need values that actually look plausible — realistic names, sentences, or structured text — you can supply your own OpenAI API key. The extension then calls OpenAI through your key to produce human-readable content for the fields. Because the key is yours, usage flows directly to your own account and quota is under your control.
Autofilly is published on the Chrome Web Store by the team behind autofilly.dev. It is listed at version 1.0.1, updated in June 2024, with a 5-star average from a small handful of ratings. It is a free developer utility rather than a commercial product, and the developer states that the extension does not collect or use your data. Treat it as a convenience tool for local development rather than something you would point at production systems.
Drop placeholder data into a form in one click to check layout, validation states, and submit behaviour without typing junk by hand.
Produce a spread of random values quickly to exercise edge cases and confirm how a form handles unexpected input.
Use your OpenAI key to generate realistic names and text so demos and screenshots look natural instead of machine-generated.
