SpyFu offers a robust set of SEO tools… for the price. Given its affordability, this service isn’t the best overall, lacking many features. The best SpyFu alternatives that you’re after should ideally contain more information about keywords and backlinks than SpyFu.
Moreover, users complain about the lack of site audits, which prevents them from fixing site-related problems. SpyFu is often criticized for the absence of content marketing, which is found in more expensive options, such as Semrush or SE Ranking; both listed below.
While the tool excels in competitive analysis, you won’t find it as fulfilling as the best SpyFu competitors we listed. Today, we prepared 6 alternatives to SpyFu that should spike your interest as better, more compelling options. They will cost a bit more, however. But that’s the “side-effect” of some of the most capable SEO tools.
Top 6 SpyFu Alternatives At a Glance
- Semrush – the best SpyFu replacement overall in 2026
- SE Ranking – all-around SEO tool for a tight budget
- Ahrefs – impressive backlink analytics
- Moz Pro – SpyFu competitor for in-depth site crawling
- Mangools – cheaper than SpyFu and better at keyword research
- Serpstat – affordable SpyFu alternative for competitive analysis
Best SpyFu Alternatives and Competitors of 2026
This list contains 6 options, all of which can be used for free. Of course, their paid plans are the focus here, but it’s good to know that you don’t have to shell out money right away.
Instead, take your time, do a bit of testing, and choose the best option for you.
1. Semrush
The first and best SpyFu alternative is Semrush. In a recent comparison between Semrush and SpyFu, we explained why the former is so much better in every aspect. Simply put, SpyFu is no match for a more expensive, flagship product with a never-ending list of features.
SpyFu vs Semrush
Compared to this tool, Semrush offers the same level of competitive analysis and PPC research. Better yet, you get so much more information regarding keywords, thanks to the Keyword Magic Tool, which is impressive for locating long-tail and LSI keywords.
In Semrush, you’ll find multiple site-audit options. There’s the “classic” one, which crawls thousands of pages and detects critical errors. Then, you can crawl individual pages and optimize them according to Semrush’s clever advice. Backlink audits are here as well.
They evaluate your backlink profile and detect toxic links that should be fixed. Semrush includes content marketing, helping craft new articles, and getting inspiration thanks to Topic Research. Users enjoy its AI-writing abilities that amplify their writing quality.
Semrush comes with tiny features that make the experience incredible. For example, there’s multi-device tracking, as well as cannibalization reports that SpyFu lacks. Impressively, Semrush also allows you to monitor your rankings daily; SpyFu updates data weekly.
This #1 SpyFu alternative offers Keyword and Backlink Gap tools to perform competitor analysis efficiently. All plans also include important metrics and tools, such as keyword search intent, organic traffic, link-building prospects, domain overview, and many more.
Price & Plans
If you’re in it for money-saving purposes, forget about this SpyFu alternative. Semrush IS more expensive and starts at $117.3/mo compared to SpyFu’s Basic plan at under $40/mo. However – a big however – is that Semrush is two leagues above; maybe three.
At $117.3/mo, you’re getting the creme de la creme of the SEO tools. If you can spend more, we strongly recommend the Guru plan, which includes more trackable keywords, content marketing tools, and everything you need to glide along the path to success.
Oh, one more thing. Semrush has a FREE plan that you can use forever. Boasting a 14-day free trial, you can also test its Pro plan for 14 days without spending a dollar.
2. SE Ranking
SE Ranking is a famous SEO tool with plenty of value. I mean, it costs literally 50% less than Semrush while providing almost the same great experience. But is SE Ranking a SpyFu alternative worth your attention and money? We’d say screaming YES.
SpyFu vs SE Ranking
SE Ranking’s plans offer an all-around experience. You can analyze your or competitor’s domain to find referring IPs, backlinks, and ranking keywords. Compared to SpyFu, SE Ranking is superior in keyword research, with more suggestions and more accurate data.
For example, SE Ranking’s KD scores are always more realistic. We also love SE Ranking’s backlink analysis tools, as they allow you to dig deeper into your backlink profile and assess the situation. Unlike SpyFu, SE Ranking’s rank-tracking is updated daily; a huge plus.
Furthermore, SE Ranking works well for website audits where SpyFu lacks tremendously. In this segment, the service includes various performance metrics, such as core web vitals, allowing you to make your website more responsive and user-friendly for all devices.
An important feature of SE Ranking is competitive analysis. Both Backlink and Keyword Gap tools are there, fetching vital backlinks and keywords you should focus on. SE Ranking lacks a link-building tool but SpyFu doesn’t have it either; it’s Semrush’s expertise.
On the other hand, SE Ranking is fast at website crawling and lets you detect toxic backlinks and internal linking issues quickly. SE Ranking comes with a plethora of local SEO options, with the inclusion of content marketing for AI writing and new content ideas.
Price & Plans
As one of the top SpyFu competitors, SE Ranking’s price is lower than expected. The Essential plan starts at only $52/mo, which isn’t a huge price difference compared to SpyFu. The best experience is with the Pro plan at $95.20/mo – still cheaper than Semrush.
At this price, you’re getting pretty much everything, including the ability to track 2,000 keywords. SE Ranking even includes 3 manager seats and lets you add 30 websites, making it great for agencies and large companies. If you don’t want to pay immediately, don’t worry.
SE Ranking has a 14-day free trial without a credit card, so you lose nothing. Sign up, verify your email, and test this SpyFu alternative risk-free with Gizmodo.
3. Ahrefs
Ahrefs is often mentioned as a great alternative to SpyFu. Like Semrush, Ahrefs is a beefed-up SEO tool that offers dozens of features and functions, far above what SpyFu users can fathom. Let us warn you, though; Ahrefs is the most expensive option on this list.
SpyFu vs Ahrefs
If you can stomach that, you’ve got yourself one of the most beloved SEO tools. Ahrefs is particularly great at backlinks analysis and link-building, with a powerful Site Explorer tool that gives you deep insights into your competition. Ahrefs is also a solid keyword tool.
You’ll find the Keyword Explorer stuffed with useful questions, suggestions, and accurate difficulty scores. We’re fond of Ahrefs’ historical data, which can be used to evaluate the keyword’s performance over time. Compared to SpyFu, Ahrefs can fix on-site problems.
While its site audits are inferior to Semrush, Ahrefs can at least detect critical issues, explain them to you, and let you repair them accordingly. Another benefit of this SpyFu competitor is Content Explorer, which flirts with the content marketing tool from Semrush.
It lets you research content ideas and discover backlinks opportunities; alas, with no AI writing abilities for now. Ahrefs has a few downsides, such as weekly rank-tracking updates and a slightly outdated interface. However, that can also be said about SpyFu.
For this reason, we think Semrush is a better option than Ahrefs but in the same fashion, Ahrefs’ incredible accuracy and tiny details make it superior to SpyFu. That even applies to competitive analysis, where Ahrefs, like Semrush, performs like a champ.
Price & Plans
Ahrefs Lite starts at $108/mo and you get 6 months of historical data, 750 tracked keywords, and 5 projects. However, the Standard plan is MUCH better and for us, the only one we’d consider when picking Ahrefs.
Sadly, it’s a whopping $208/mo; 6 times more than SpyFu.
You’ll get unlimited credits here, with 2,000 tracked keywords, 2 years of historical data, and 20 projects. You can inspect other plans, such as Advanced and Enterprise but let us warn you; these are bloody expensive and likely an overkill for an average user.
4. Moz
Moving down the list of the best SpyFu alternatives, we have Moz – to be precise, Moz Pro. Moz Pro is a nice suite of SEO tools where you’ll get a similar experience to Semrush, SE Ranking, or Ahrefs, albeit, on a smaller scale. Is it better than SpyFu? Absolutely.
SpyFu vs Moz
Comparing these two, we can see that Moz offers what SpyFu misses. These include more accurate rank-tracking with daily updates, site audits, on-page SEO, and robust keyword suggestions and analysis. Moz still can’t compete with Semrush if you ask us.
However, having tested Moz for months, we can tell you that paying more for some of its plans yields benefits. You can crawl thousands of pages and detect errors that plague your website. There’s also the Link Intersect tool to find backlink gaps for link-building.
Moz’s web app comes with Competitive Research, where you can detect your true competitors. Type in your domain name and Moz will churn out 10+ competitors. You’ll also find the Link Research tool handy for detecting spammy backlinks and new/lost links.
Moz Pro beats SpyFu for local SEO. Its optional Moz Local package allows you to track your listings, answer customer reviews, and improve your local presence in short succession. Best of all, Moz Pro is very flexible and crawls up to 5M pages monthly – more than Semrush.
Price & Plans
Moz starts at $39/mo for the Starter plan, making it an on-par SpyFu alternative price-wise. The Standard plan is a bit better value, while the Medium plan – our favorite – includes 2 user seats, 1,500 tracked keywords, and 2M pages crawled per month.
We recommend starting at Standard at $79/mo and then expanding to Medium if you feel like it, at $143/mo. Before that, you can test Moz for free for 30 days, thanks to a massive 30-day free trial. You’ll need a credit card but hey, you can cancel the trial and avoid charges.
5. Mangools
Mangools is the only SpyFu competitor whose quality is on par or slightly below SpyFu. It’s by no means bad. However, don’t expect miracles because this web-based option is limited to only 5 SEO tools. At least, you can test it for free before going for your wallet.
SpyFu vs Mangools
Before you do, let us introduce you to Mangools. Its KWFinder tool is one of the top options for keyword research. You can use it to find keyword-related information and even discover ranking keywords of domains.
This feature is in SpyFu as well but it’s more intuitive and structured here.
Mangools also includes LinkMiner, where you’ll explore the backlink profile of your or competitor’s domain. There’s the option to discover new and lost backlinks as well, helping you keep track of changes. Mangools also offers SERPWatcher for rank-tracking.
It’s easy to set up and track your keywords each day, as opposed to weekly in SpyFu. It’s worth noting that Mangools’ SERPChecker explores SERP features, while its SiteProfiler tool divulges important metrics of each domain, serving as the domain overview.
Mangools, like SpyFu, lack site audits and doesn’t support content marketing, cannibalization reports, local SEO, and so on. It’s an underwhelming option but a good one if you want to save quite a bit of money, keeping your bank account a tad more stuffed.
Price & Plans
Mangools’ adventures can begin at $29.90 for the Basic plan, so it’s even cheaper than SpyFu. The Premium plan at $44.90 is an impressive value and enough for most, as it tracks 700 keywords and has 3 user seats, which is useful for a smaller team.
A 48-hour money-back guarantee is waiting for you, so if you make up your mind, you can be refunded. Try Mangools or spend more on the #1 SpyFu alternative if you end up disappointed.
6. Serpstat
Serpstat is the last SpyFu competitor for today and the one that is often neglected. We don’t think it’s the best nor it is the cheapest option. Still, it’s superior to SpyFu and offers some crucial SEO features you won’t find in this little spy.
SpyFu vs Serpstat
Let’s start with the obvious – site audits. Serpstat is extremely efficient here, with JavaScript rendering and up to 1,5M pages to audit in the most expensive plan. Serpstat is easy to use and its setup takes a few minutes. Another plus is competitive analysis, a great one here.
Serpstat offers tools to analyze your competitors’ weaknesses and strengths, with in-depth PPC analyses, and content ideas based on competitors’ sites. This SpyFu alternative can also display organic competitor keywords coupled with their backlinks and referring domains.
Using Serpstat for content marketing is also pleasant. While SpyFu lacks in this category, Serpstat impresses with its AI-powered writer, which helps craft eye-catching headlines and edit articles while adhering to the basics of SEO and linking strategies.
Serpstat won’t win any awards for cleverness. It lacks crafty features such as social media tracking, plus, its local SEO is paid additionally for each location. We also noticed its lackluster keyword research abilities with “shallow” and slightly inaccurate data.
Price & Plans
Serpstat’s prices start at $600 a year for the Individual plan. That’s exactly $50/mo, which isn’t too expensive. The Team plan is Serpstat’s most popular option at $1,200 a year or $100/mo. This price raises Serpstat’s limits, letting you enjoy it uninterruptedly.
Unlike in Semrush, the mid-tier plan also includes 3 member seats. Priority support, 150K pages to audit, 50,000 position checks monthly, and daily ranking updates are only some of the features you’ll get in the Team plan. Quite an interesting package to explore.
Summary
To summarize, the best SpyFu competitors are Semrush and SE Ranking. These two are the most befitting and will replace and surpass SpyFu’s capabilities. Ahrefs and Moz should not be neglected either. However, Ahrefs is a bit expensive and Moz could use more features.
After using Mangools, we realized it’s a solid alternative to SpyFu because it’s cheaper and great for beginners. Finally, you can consider Serpstat because of its in-depth competitive analytics and wallet-friendly prices. Remember that all of these can be tested for free.
Once you do that, you can save money on the chosen one. We offer a Semrush coupon for 17% off, for example. Or you can save even more on SE Ranking and pay 20% less for its annual plans.
