Lightning Autofill alternative: how EchoFill compares

Facts about Lightning Autofill are from its pricing page and home page as of October 9, 2026. Prices change, so check theirs before you decide.

Short version: Lightning Autofill is a powerful, long-running tool (since 2010) built around rules, macros and text expansion. EchoFill is built around one idea: fill a form once and it fills itself next time, with no rules to write. If you mainly refill the same kinds of forms and want unlimited fills free, EchoFill is the simpler fit. If you want macros, text expansion or JavaScript automation, Lightning Autofill does more.

Why we built EchoFill after using Lightning Autofill

We used Lightning Autofill during a long job search, while sending hundreds of applications. It was useful at first. But the rules for each field had to be very specific, or the box simply didn't fill, and keeping them right took time. It also started out free for how we used it and got more expensive over time. Those two things are a big part of why EchoFill has no rules to write and a free plan with no daily cap.

The real difference: rules vs. recording

Rule-based fillers are flexible: you decide exactly which value goes into which field, and you can match fields with patterns. The cost is setup. Every new form means writing or adjusting rules, and when a site changes its field names, rules can quietly stop matching.

EchoFill skips the setup. You fill a form the normal way, click Record this form, and EchoFill saves what you typed. Next time it matches fields by their label, name and placeholder, so it keeps working when a site's hidden IDs change. On sites you approve, it fills as soon as the page opens; anywhere else it's one click.

When Lightning Autofill is the better choice

• You want text expansion (type a shortcut, get a paragraph) and autofill in one tool.
• You need macros or JavaScript automation that go beyond filling fields.
• You fill rich-text editors often. EchoFill doesn't fill those yet.
• You use Firefox.

When EchoFill is the better choice

• You refill the same kinds of forms (applications, government forms, listings, admin tools) and don't want to write rules.
• You'd hit 10 fills a day on a free plan. EchoFill's free plan has no daily cap.
• You want your answers kept only on your device, with no account.
• You want to see and undo every fill.

Switching takes one form

There's nothing to import. Open a form you fill often, fill it the usual way (Lightning Autofill can even do it for you), then click EchoFill → Record this form. That's your first profile.
