Publisher Rocket Free Alternative
KDSPY is certainly an option worth considering as a Publisher/KDP Rocket Alternative particularly as it’s free to try.
Identifying potentially profitable categories rather than getting ideas from keywords is the driver of KD Spy.
KDP SPY & Finding Profitable Keywords
Right from the start, KDP Spy takes you into a categories page so you can compare one category to another in order to see which is more successful.
To see what’s working well within categories, the KDP SPY ‘Word Cloud’ feature aggregates common words across profitable titles within a given category. As useful as this may sound, the end result is often just a list of obvious words that don’t help much with generating a new idea.
Publisher Rocket VS Kindle Spy
Publisher Rocket is a huge upgrade from KDSPY, in the sense that it has not only the same features as Spy but much more in the way of analysis.
According to some users, Kindle Keyword Spy makes it much easier to find niche markets than KDPR, but both have the ability to cull this data plus, KDPR has a new Category Hunter feature that newer users rave about (more on this later).
Kindle Top Seller Lists
KDPR lists the top sellers within the other existing comparison charts providing a total view of the niche and keyword positions. Within listings on Spy, best-sellers are simply identified with an orange label on search results.
Kindle Search Data from multiple Amazon Websites
With the latest version of KDSPY (v5), you can access search data from Amazon stores including USA, UK, Italy, Spain, India, Germany, Canada, Australia, Japan and Mexico.
Publisher Rocket Alternative
If you simply can’t afford Publisher Rocket, then KDSPY is certainly a very worthwhile purchase at $69.

KDP SPY
KDP SPY is a variation on the names of both KDP Rocket (Publisher Rocket) and Kindle Spy. This can lead to some confusion as there is also a browser extension that goes by this name.
Both Publisher Rocket and Kindle Spy are vastly superior products in our opinion which are constantly updated to serve customer needs.
Kindle Samurai
Samurai is the lowest in the ranks for keyword software in this category. It is slim version of all of them, at the lowest cost, and with the least features, particularly with keyword identification and demand data.
KD Spy easily surpasses Kindle Samurai. KDP Rocket, however, seems to stand above the rest with the most advanced, full capabilities of all. It boasts all features in one software tool.
KDSPY VS Kindle Samurai
KD Spy initially came out as a more advanced version of Kindle Samurai which is almost solely focused on keyword research.
Due to the light weight and highly limited features of Samurai, Spy became the best go-to option for Kindle self-publishing writers at the time.

Publisher Rocket Review
Clearly the goal of any self-publishing tool is to help generate or refine your e-book idea so that it will be popular, will be read, and can lead up to the creation and sales of any further publications. It makes it easier to place your brand within a popular field so it will get noticed.
KDP Rocket 1.0 upgrades to Publisher Rocket 2.0
Google & Amazon Search Volume – KDP Keywords
A detailed feature in KDP Rocket allows you to see how often keywords are searched for on Google along with an estimate for Amazon Kindle Keyword searches.
So, in addition to getting the right keywords to begin with, Rocket allows you to see the keyword search rankings in real time.

For example, as you are doing an idea search, the idea page comes up with a list. First, you will be able to see the listing of ideas that match, then see the amount of competition you will have and the earnings these publications are making.
The number for estimated Amazon searches is unique to Rocket and gives it a clear advantage over KD Spy, Kindle Samurai and other Kindle self-publishing tools.
Analyze Tab
KDPR’s analyze tab allows you to get a clear analysis of all publication volumes. Comparison data is sought by most writers and also they require an understanding of how categories are ranking. With this, you can have:
- Precise keyword analysis software data, showing what publishers and writers are presently involved with re: subjects within the niche markets you wish to write for
- Finds and identifies publication volumes for comparison
- Kindle Spy and Kindle Samurai do not offer this feature
The best aspect of the Analyze tab is the comparative profile it will provide so as to show you whether a particular book is worth writing or not. If the competition is too fierce, don’t bother.
Kindle Competitors Analysis
With regard to the competition, you will want to see everything you can about competitors. Besides the search volume and basic statistics, more is better in this case and, Publisher Rocket can definitely offer more.
Before going into any book venture you plan on self-publishing, please understand how hot and heavy the competition is.
If you have the experience, you understand that it’s critical to know where your competitors are falling in the charts, how old their publications area and possible available sub-niche placements.
Sub Niche Research
The sub-niche markets still have higher potential. When you do find those and they seem to work with the ideas you are fostering, look further with the competition searches tab to get a full picture. KDPR software makes it incredibly easy to do so.
You can see everything, absolutely everything about your competitors! Better still, it all shows up on the first page. Scroll as you see fit and then click on any you are interested in to see some real numbers.
If you want to know the number of reviews written for a book, you will find it with Rocket.
In addition, you will find the Amazon Best Seller Rankings and how old the book is, measured by days.
Kindle Category Finder
As mentioned, KDP Rocket has many similarities to KDP Spy. Spy was formerly the best way to find book categories which would be practical for writing within so publishers can make money. After all, this is the main idea and goal to accomplish for most of us.
Kindle Category Hunter
Publisher Rocket has added a new and exciting feature known as “category hunter” which gives it even more of an edge over KDP Spy.
What it does is very much like it reads. It helps you to hunt down the ideal Kindle categories for maximum publishing potential, leaving more time to research and write the content well.
The orange, bright flashing colors show up again to identify the best-sellers. The displaying of these categories will also provide ideas for brand new categories in which to publish more selling material.
Publisher Rocket UK
In September 2020, a much sought after update was added to Publisher Rocket. This was the inclusion of the UK market meaning UK specific categories including all the usual top notch analytical options to dig right down into that precious data and unlock great opportunities.
New Features added Regularly
There are many other interesting features to the KDPR software. Naturally, you will need to purchase the software and use it for it to be effective. It is still a good idea to leave your Kindle tab open while working, as it will help in the long run.
KDSPY Free Alternative – Publisher Rocket Trial for 30 Days
Sign up today and you can avail of a Publisher Rocket free trial for 30 days. Remember it’s absolutely gratis with a money-back guarantee.
You won’t find any torrent downloads or cracked versions of this software that are safe, reliable and up to date.
Try KDP Rocket free it for a month and see why it offers so much value at $97. As you can tell from all of the above, it’s certainly a very worthy KDSPY alternative.
Cons to Publisher Rocket
First, even though KDPR does a great job of displaying all categories, this display is mixed up with other Kindle book titles and physical books.
This can be confusing to weed through. Perhaps they were moving too fast to develop a more friendly user interface for this feature.
Ratings from other e-book companies
One thing that would be good for an add-on is the capability to view the ratings for paper-published books, publishing from other e-book companies, as well as Kindle statistics for their titles.
You already understand that Kindle is your platform, as you want to be a self-publishing writer for Kindle.
This all makes sense, but KDP Rocket definitely takes a slide by not providing such information at this time, at least not in a manner that is easy to read and identify as you are building your project from the ground up.
Full Reviews
Second, with previous versions of Rocket, the software actually gave you the ability to see the whole, actual reviews for publications on Amazon. This was useful because, often, a writer needs to read reviews for reasons of both writing and editing.
The present version no longer offers such a feature. It does still list the number of reviews, just not the specific reviews themselves. On the prior version, all you had to do was click on the publication for a full review.
How Can Publisher Rocket Work for Me?
If you are a writer, particularly for writing top-notch articles from scratch or e-books, there is no way this product could not be useful to you. This is, of course, if you plan on publishing through Amazon.
If you have used or still use KD Spy, Kindle Samurai and/ or other Kindle software, it is important to at least try KDP Rocket and see if it serves your needs. It will make keyword discovery and generation so much easier.

Notice all the features to your advantage. In the event that you are learning about content and article writing, you will also find this software well worth the purchase.
You can always try out some other software programs aimed to different publishers if you decide that you dislike KDPR. However, considering that Amazon is becoming the market leader for all e-book publishing, it will probably be best to work with Rocket and publish with Kindle.
