OVERVIEW

Lightning Autofill is the ultimate form-filling tool for maximum productivity and convenience. Tired of wasting time filling out forms and repeating the same tasks over and over again? Lightning Autofill transforms how you interact with online forms, handling everything from account registration to shopping cart checkout with ease!

Lightning Autofill combines form filling, automation, macros, text expansion with autocompletion, text snippets, random data generation, and form recovery in one powerful tool. While the browser's built-in autofill only handles basic fields, Lightning Autofill works on complex multi-page forms. It's perfect for advanced automation like monitoring product availability or drops and auto-purchasing when in stock.

BENEFITS

🚀 Boost your productivity: No more manually filling out forms—get more done in less time.
💰 Save money: Catch limited-time offers and flash sales before they sell out.
💸 Make money: Automate online sweepstakes and survey-for-gift-card sites like Crowdtap.
🔔 Never miss out: Secure reservations and appointments the instant a slot opens up.
🧠 Reduce mental fatigue: Free your mind from repetitive tasks to focus on what matters.
🤙 Reduce repetitive strain injuries: Avoid hand and wrist pain from constant typing.

KEY FEATURES

⚡ Autofilling: Autofill way more form fields than the built-in autofill (text inputs, checkboxes, radio buttons, dropdown menus, multi-select lists, rich text editors, reCAPTCHAs).
🦾 Automation: Automate tasks with JavaScript and macros (click elements, trigger events, open tabs, reload pages, scrape HTML, customize page appearance, wait, and more).
🪄 Rules generator: Easily create autofill rules without coding.
🔤 Text expansion: Expand shortcodes directly or through autocomplete.
📋 Text clips: Insert boilerplate text snippets from the context menu.
🎲 Variables: Generate dynamic content, random data, and more.
🎯 Smart targeting: Find fields using simple text, regular expressions, CSS selectors, or XPaths.
🗂️ Profiles: Create, duplicate, and sort rule sets for better organization.
⌨️ Hotkeys: Execute profiles and manage rules using keyboard combos.
☁️ Cloud sync: Manage your data in Google Sheets and sync it across devices.
💾 Import/Export: Back up and restore your data locally and remotely.
🛟 Peace of mind: Recover form data in case of crashes.
🚫 Exceptions: Exclude specific pages or websites from autofill.

PLANS

🆓 Free: 10 profile executions per day (sufficient for casual users)
🌟 Plus: unlimited profile executions + cloud sync (connect to Google Sheets)
💎 Pro: everything in Plus plan + JavaScript rules and variables + reCAPTCHAs

FAQ

❓ Doesn't the browser already have an autofill feature?
🅰️ Yes, but it's very limited. The browser's built-in autofill only works with address and password fields, and you still have to manually select from a dropdown menu every time. Lightning Autofill works on all form field types (except file inputs), and fills them instantly with zero clicks.

❓ Can I automate things like clicking buttons and auto-submitting forms?
🅰️ You sure can! With JavaScript rules, Lightning Autofill can do pretty much anything that you can do manually, but much faster. Lightning fast. And it never gets tired.

❓ Are you tracking me?
🅰️ Absolutely not! We're big on privacy ourselves, so Lightning Autofill has no Google Analytics, no tracking pixels, no cookies—nothing. Read our Privacy Policy for details.

If you have other questions, our Discord and Reddit communities are ready to help.

PRIVACY & SECURITY

We respect your privacy. Lightning Autofill never tracks your browsing history or collects any personal information. Your data is stored locally on your device (unless you use cloud sync) and is not encrypted, so please use caution when autofilling sensitive information like passwords and credit card numbers.

SaiKarthik Chandra 2025-10-28: This is toooo much.... i used to have respect when it was free. but now i see a quite different phase. and now i hate this and uninstalled it. For every friend you refer, both of you get 10% off your subscriptions. Refer up to 10 friends, and discounts stack. Hit 10 and your subscription is FREE! If a referred friend cancels, you lose that 10% discount. Your discount kicks in on the next bill, your friend’s on their 3rd. Only subscriptions purchased through Stripe Checkout are eligible.
Vlad Sharanhovich 2025-10-16: 10 auto-fill per day for free and then you have to pay $5 (or $10 for so-called "pro") a month? Are you kidding? Sorry guys, your pricing is nonsense. And it's not such a "complex" piece of software to ask for $5 a month to use. I'm paying the same for my expenses and budgeting software for example, which is much more elaborated tool. Anyway, I understand that you need to make money and support development, but make it reasonably priced to justify the switch to paid model like $1 a month for simple functionality (no recaptcha). Or make free tier actually usable - 10 fills a day is complete joke. But for now, I'm off to a free alternative autofill extension :).
Rabi Sol 2025-10-01: free for 14 years and now pay to use.
Joe_George_IIMRohtak 2025-09-25: Awesome tool
Soumen Saha 2025-09-08: How about not spamming users with nagging reminders by repeatedly launching the entire browser just to nag about developer mode, especially when the user isn’t even using the browser? That’s exactly what used to PUPs. Stop spamming people!
Ayush Chhanganni 2025-09-05: It doesn't work for my use case, I need to fill certain types of google forms and it doesn't work for me as its shown in their document page.
Mirzag411 Mahmood (Akhtar) 2025-08-11: very nice
Nkansah Rexford 2025-08-10: My bad. Not sure what I was expecting, but didn't think of this extension to have a "paid" part. Plus, I don't think I'd want my form data stored on the "cloud sync" (again, I can't think of why i'd wanna do that) Again, my bad. I thought all this was purely offline, and nothing goes to some "cloud" somewhere. Anyway, I created my offline "Lightning Autofill" with a single sentence prompt. It actually requires _more_ code to make it paid than free. lol
Hitesh Ramteke 2025-07-30: it was a great tool until they put money on it: now people have to pay . a good piece of advice in 2025 is to find other alternatives instead of paying the money
M Abbasi 2025-07-29: Lightning Autofill has seriously boosted my productivity. I use it daily to automate form submissions that would otherwise take hours of repetitive typing. It's intuitive, lightweight, and incredibly fast—far better than other autofill extensions I've tried. The ability to create multiple rules for different sites is especially helpful. Highly recommended for anyone dealing with routine online forms. Saves time, reduces errors, and just works. Great job to the developer team for creating something so efficient and user-friendly!
Norm Cartier 2025-07-27: Finally, a auto-fill that works. It's GREAT!
Andrey Okoniewski 2025-07-24: paid app, 10 tries is bs, didn't manage to configure it properly and got over the limit. For some reason i wasn't able to get autologin to work on TrueNas GUI login.
R H 2025-07-23: I'm so glad the developer decided to put some more love into the products.. It's getting better and better.
What Sigma 2025-07-23: Works fine once you get used to how it works. Actually, I'm only using like 10% of its features.
mehdi king 2025-07-22: for removing free version
ujval borole 2025-07-21: I actually used this for a while but ran into issues on some sites… switched to QuickFill recently and it’s been flawless so far. Kinda surprised it’s not more popular tbh.
Moby Dick 2025-07-21: This app is my secret weapon in my crypto automations. PRO TIP: Restart Chrome whenever there's a version update. It tends to act weird after updates.
Patrik K 2025-07-15: 10 forms a day are free. If you need more, you'll have to pay $4 per month. No thanks.
ASB 2025-07-10: Very nice application, I hope it will work.
Sourav Sarkar 2025-07-08: Great
akın keskin 2025-07-07: great one
Pavel Shalygin 2025-06-26: The first app in my life where I was able to set up automation but couldn't use it. Where's the “fill” button? I couldn't find it. UI by god.
Mitchell L 2025-06-23: $5 a month, no thanks.
Diosbel Suero 2025-06-20: I Like it
kashif kazmi 2025-06-16: make my local storage empty while reloading the page
Joel Carlos 2025-06-16: Deletes all local storage contents
Mắt Khoa 2025-06-16: VERY BAD, PLEASE COMEBACK VERSION 13.X
Don Howell 2025-06-16: It has a little bit of a learning curve, but it is well worth the investment. It has saved me TONS of time for years now. 2025 Update: Still saving me HOURS every week. They are adding new features and fine tuning all the time. This is well worth the subscription! They have great support on discord server as well.
null 0 2025-06-15: after trying to test all my extensions, found this is what cause logout on every site.
Kasauli Town 2025-06-14: Breaks feedly.com when installed. Please fix. Additionally, GUI can be much better.
Anderson Barcellos 2025-06-13: After a disrespectful act towards its user's and jamming up with my work, I've found a solution through one of the posts back when they killed the extension! I am so grateful to Derek McCoy! God bless you, man. "If anyone is after the old version, get it from here: https://www.crx4chrome.com/crx/361757/"
James Bernoski 2025-06-11: Would be willing to pay a flat fee for this because it's a great addon, but 4.99 a month forever is too much for me. We already have enough subscriptions in this world. Also annoying to see them doing some subscription fundraiser to drop the price, honestly would just rather have my data sold then have to subscribe/unsubscribe whenever I need to use this addon.
sandeep pvri 2025-05-28: THANK YOU
Michael Hylton 2025-05-27: Once I figured it out, it's been my daily autofill tool and I'm always finding more ways to automate. I agree with some of the other reviewers's impressions of the free version, which I've used for a while with mixed results, but the real power is in the premium version. The ability to click buttons, run Javascript, and create variables helps me save tons of time on everything. I have nearly 20 profiles. Syncing it to Google Sheets is amazing because managing profiles in the extension can be buggy. If you can afford the monthly fee, it's worth it. It saves me probably ten hours per month, so that's $1 per hour. One last thing: it also pays to inspect elements and figure out how to write it on your own instead of auto-generating it.
Artem Svyryd 2025-05-16: Best auto filler i've used. Fully automated my work tasks. Big thanks for developing extension like this.
Kha 2025-05-15: Works as intended. Great for job application forms that are repetitive :)
seven heven 2025-05-12: "I did everything I could to keep Lightning Autofill free for over a decade, but as the user base grew, the costs became too much for me to manage on my own" - Tom D (developer) negative 600,000 users later, over half have uninstalled. Still too much?
oniks 2025-04-22: Cool extension, but UI of QuickForm extension is better and it is for Free.
Adarsha Secondary Boya 2025-04-21: Thanks for helping me
Artem Prokopenko 2025-04-18: I set up all the necessary fields, tested it once, filled it out once, and two days later, when I tried to use the plugin again, it told me I had exceeded the limit and had to buy the paid version. I had barely used it — maybe three times at most. I believe it’s a scam that doesn’t even provide the promised limit and pushes you to pay after you’ve already set everything up. I’m not against paid versions at all, but I didn’t even get what was promised in the free version.
Robert Matsumura 2025-04-17: doesn't work. generated my autofill form, worked for about an hour. the next day during the drop, none of my credit card info was saved.
Joel Whitman 2025-04-15: Used to work great until they limited it to 10 executions per day. Now it's worthless.
Samir Agrawal 2025-04-14: Works seemlesly. Very helpful autofill tool.
Pat MySecret 2025-04-08: 2025: The Freemium only gives you several fill-ins.. I will look for other apps. It's nice and can be used across sites. Start with Options. click the + button at the bottom to start adding fields above, fill them, and save.

Aome Art 2025-04-01: Why does it want me login using my google account now? The downfall of this extension.
uf xy 2025-04-01: Sometimes it works, sometimes it doesn't。
Leonel Salgado 2025-03-29: Muy Útil para llenar facturas del SAT ya que el sitio oficial solo te permite 20 productos, con esta extensión puedes agregar a tu inventario los que quieras. Ojala en un futuro se pudieran categorizar los perfiles (want to categorize profiles) Desde que pusieron versión de pago esto se fue a pique. No me sirve el modelo de suscripción, tal vez si fuera un modelo de créditos podría considerarlo. Porque solo lo utilizo 1 dia al mes y ese dia necesito al menos unos 80 usos. Por eso el modelo de suscripción me parece muy costoso y prefiero copiar y pegar aunque sea más tardado.
Sajjad Haq 2025-03-25: Saves me a fraction of my day everyday, thanks
Phong Thai 2025-03-20: useless, cant fill any field
