The short verdict: Ubersuggest wins on price and included data, KeywordTool.io wins on platform breadth and API muscle. They overlap on one job, mining autocomplete, and disagree on everything around it.
Full disclosure before the comparison: this site's own tool competes in this exact category, so we will show you the free route too and let all three stand on merit. Pricing verified July 2026.
| KeywordTool.io | Ubersuggest | |
|---|---|---|
| Free tier | Suggestions only, numbers hidden | A few searches a day, with numbers |
| Entry plan | $88/mo ($68/mo annual) | $29/mo |
| Higher plans | $188 / $388 / $788 per month | $49 / $99 per month |
| Lifetime option | No | Yes, one-time purchase |
| Volume + CPC data | Pro plans only | All plans |
| Platforms mined | Google, YouTube, Bing, Amazon, Instagram, eBay, more | Google-centric |
| Beyond keywords | Focused: keywords + API | Audit, backlinks, tracking bundled |
| Daily capacity (entry) | 50 requests, 50,000 keywords | 150 searches |
Two different bets
KeywordTool.io in practice
KeywordTool.io mines autocomplete across more platforms than anyone: Google, YouTube, Bing, Amazon, Instagram, eBay, Play Store and beyond, one interface, one API.
The 2026 pricing is unapologetically professional: Starter at $88 a month ($68 annual) with 50 daily requests and 50,000 keywords a day, up through $788 for agencies. Every plan includes API and MCP access, which is the real product for many buyers.
The honest limits: the free version shows suggestions but hides volume, CPC and competition, and casual users are simply not who it prices for.
Ubersuggest in practice
Ubersuggest treats suggestion mining as one feature of a budget suite: keywords with volumes on every plan, plus audit, backlinks and rank tracking, from $29 a month with a lifetime escape hatch.
The honest limits: platform coverage beyond Google is thin, daily search caps are real, and the upsell energy is constant.
Choose KeywordTool.io if...
- You need suggestions from platforms beyond Google, especially at bulk scale.
- An API feeding your own pipeline is the actual requirement.
- The $68 to $788 range reads as a business expense, not a personal one.
Choose Ubersuggest if...
- You want suggestions and volumes in one affordable subscription.
- The bundled audit and tracking replace tools you would buy anyway.
- The lifetime deal matches how long you plan to do this.
The free route both compete with
Autocomplete itself costs nothing, and mining it does not have to either. The keyword tool on this site streams Google, YouTube and Amazon suggestions free, up to 10,000 per run, and the free volume stack sizes the results.
The paid tools above earn their money on platform breadth, APIs and bundled extras, not on access to suggestions. Buy them for those reasons or not at all.
How we compared them
Pricing verified from both vendors' pages in July 2026, USD, annual figures marked. Both tools were run on identical seeds. And yes, this site competes in the category, which is exactly why the free route sits in plain view above.
The one-line takeaway: KeywordTool.io sells breadth and pipelines at professional prices, Ubersuggest sells an affordable bundle with numbers included. The suggestions themselves? Those were free all along.
