[Windows] SlimBoat is a shockingly fast, full-featured, and portable web browser [Mac OS X, Linux]

Slimboat PortableI am a firm believer that there are great browsers out there that many of us have not tried. Don’t get me wrong, I like Chrome and Firefox as much as the next guy. That being said, I enjoy using SeaMonkey and Maxthon more. However, there are still a number of browsers I have not tried, and one of them is SlimBoat. After hearing from dotTech users that there is a SlimBoat version, I’m very interested to say the least. I have tried other portable browsers, and they were crap. So let’s see how SlimBoat stacks up!


Main Functionality

SlimBoat is a full-featured, portable browser. It is shockingly fast and comes bundled with some very helpful features, like an ads and pop up blocker, Facebook integration, and a YouTube downloader. The navigation time between webpages is small, and it prides itself on using few system resources.

SlimBoat works on Windows, Mac OS X, and Linux. We specifically reviewed the Windows version.

Note: Please realize that there is an inherent risk in using a web browser from a relatively unknown developer. If the developer of the browser is malicious in anyway, all your internet activity and logins and personal information can easily be stolen by the developer. We are not saying SlimBoat is a malicious program. This is just a general cautionary note about browsers. Proceed further at your own risk. dotTech and its writers are not responsible for any gain or harm incurred.

Slimboat Portable ScreenshotI am on the internet a lot, so I tend to be picky about my browser. I have tried other portable browsers before, and none of them lived up to my standard. So when I heard that SlimBoat had a portable version, I was looking forward to giving it a try.

For those of you who don’t know, SlimBoat is a very light-weight browser based on the webkit rendering engine. As with other browsers it is available for multiple platforms, but we are trying out the Windows-based one here today. The browser prides itself on three major things: Being fast, being secure and coming bundled with a lot of great features. To my surprise, it was able to hit on all three of these key areas.

When I first started up SlimBoat it took me through a little mini setup. It asked me basic question like: “Would you like to set SlimBoat as your Default Browser?” and “Would you like to import bookmarks?” This was a great way for the program to start out, because it takes the guesswork out of trying to figure out where to go to do these kinds of things. For anyone who has used as many browsers as I have, you already know that many of them list this kind of information in different locations.

From there, I started surfing the net. The default homepage brings you to a Google custom search and some popular websites listed below it. Not really a big fan of Google’s “custom” searches, but your homepage can be easily changed, so no big problem here. As I started visiting all my favorite web pages, I couldn’t help but notice how quick the browser loaded them. I would say that it is as quick, if not maybe a little quicker than, SeaMonkey, which is already faster than other popular browsers like Firefox.

The biggest problem I had with the program came when I visited some sites that had big Flash games on them. Although the program ran smaller Flash games perfectly, I noticed it struggling a bit with larger ones that had a lot going on. This doesn’t happen with my other browsers, so I have to assume it was SlimBoat.

After that, I started checking out the features this program comes pre-bundled with. This includes things like Facebook integration, a YouTube video downloader, an ads and pop up blocker and even a little weather forecast widget. Adjusting these tools is as easy as clicking on the “Tools” tab and selecting “Options”. This will bring you to a small screen that will allow you to adjust these features as you see fit. The ones that I tried out all worked great, which was refreshing. On top of that, I loved the fact that they came pre-installed, as many of these “features” are things I choose to add on to my other browsers anyway.


Overall, I can say that SlimBoat is, by far, the best portable browser I have used. There may be a better portable browser out there, but if there is, I haven’t stumbled across it yet. During my time with the portable browser, it did not freeze or crash. If you are looking for a good portable browser, I cannot recommend SlimBoat enough.

    Yes, it is blazing fast. Beat the other browsers hands down. Unfortunately, alarm bells went off: Zemana went flashing red (which it only does in the rarest of cases) and Emsisoft blocked it because it was calling home to some shady address. So, I quit using it (alas).

    Does it ‘have’ NoScript.
    I don’t understand why people are using browsers that lack NoScript. It really is brilliant, and a necessity.
    Here is an interview with the creator of NoScript –

    Bringing this article back out of the wood works.

    QupZilla is another browser based on the QTwebkit engine. IMO it feels a lot like Opera; menus and speed dial. It also has a built-in Ad-Blocker. I think everyone should try it out. Justin, maybe you’d be interested in reviewing this browser.

    Thanks Stephen,
    I am glad someone took the trouble to reply on something which I believe is an important matter.
    Could I turn it off globally, and then allow it on some sites ?
    Would that ‘allowing’ setting per site, be persistently remembered ? (or would that be flaky like you say the per site blocking is ?)
    Thanks again for taking the trouble to respond.
    PS Are you using either of the two browsers (SlimBoat or SlimBrowser) on a constant basis, as your main browser ?
    PPS Is the option to turn off Javascript the one in Download Control OR is the setting somewhere else ?

  • Justin, SlimBoat is a really new comer in the ring of browsers. However, the same company, FlashPeak Inc, develops another browser called SlimBrowser based on Microsoft Trident engine. SlimBrowser (http://www.slimbrowser.net) has been around for more than 10 years and enjoys a larger following. Both browsers have similar features. The key difference between them is different engine under the hood.

  • @Rob (Down Under):

    SlimBoat doesn’t support NoScript. But it does come with something similar:

    1. You can disable scripts globally or a per site basis. But the per-site setting is not remembered persistently.
    2. It comes with built-in ad blocker to block out most of the ads.
    3. Flash can be disabled globally or a per site basis (available under menu Tools:Download Control). The per-site setting is not remembered persistently.

    @Janet: Isn’t Google’s toolbar defunct now? I believe Google stopped supporting it.

    @riya: Agree! I’ve been using Palemoon for about a year now, and I’m very satisfied with it. It’s a genuine 64 bit fork of Firefox (Mozilla source code recompiled with optimized settings for modern cpus, and accessibility features & parental controls removed). All the Firefox extensions can be used with Palemoon.

  • Janet

    Does it support the Google Tool Bar? I use it all the time. I was shocked to find Chrome does not have all the functions on the Google Tool Bar and does not allow installing it!

  • riya

    Palemoon is also a good and portable browser :)

  • Ashraf

    @Rob (Down Under): I don’t use NoScript o_O
    @Justin: Thanks Justin, updated the article.

  • @AFPhys: Sorry If I didn’t make it clear. The “Pop up Blocker” that I talked about in the review is the “Ad Blocker”. It comes pre-installed with the browser. You can adjust the settings of the Ad Blocker by going to “Tools” > “Options” > “Ad Blocker”

    @Rob (Down Under):
    I haven’t used it yet, but I have the same question regarding NoScript and SlimBoat. Their website is pretty slim on details about the browser, and their FAQ is blank.

    The closest I have been able to answer my questions is by looking at their version history, and I note that in this version:

    Update language files.
    Minor bug fix in ad blocker.

    Earlier versions list ad blocker, also, though I didn’t see any mention of plugins in general at all. Unfortunate.

    I guess I will have to find out for myself by downloading it and eventually using it, though that won’t be done today.

    On the recent DotTech article, where SlimBoat got recommended, I raised a question regarding NoScript
    I am pretty sure that anyone who uses FF would be using NoScript (or would be if they knew about it)
    . . .
    Did you discover if SlimBoat has a ‘NoScript’ capability ?
