  • Suggested by freakazoid

SRWare Iron is a privacy-enhanced web browser based on Chromium, the open source project behind Google Chrome. By default, Iron sends out less information as compared to Chrome (e.g., creating a unique user ID or the submission of entries to Google to generate suggestions), making it potentially more privacy friendly and secure in operation.

Iron supports both official and unofficial themes and some extensions from Chrome. Additionally, to enable blocking ad servers, a 'adblock.ini' is present in the program folder, and Opera's 'urlfilter.ini' can easily be converted to Iron's accepted format by following these instructions (or see comments below).

Note: It is recommended you change the homepage. The Iron default homepage may contain ads or links to fake adware-containing downloads.

Alternative packages:

  • Iron Portable (adds password portabilization, path portabilization, registry cleanup and Java support)
  • X-Iron (idem)

System Requirements: Win7 / Win8 / Win10
Writes settings to: Application folder
Stealth: ? No. It creates some registry keys in 'HKCU\Software\Chromium'. Start with --incognito parameter to prevent saving history and cookies after program closes.
Unicode support: Yes
Path portability: No
License: BSD
How to extract: Download the "Portable" ZIP package and extract to a folder of your choice. Launch IronPortable.exe.

XP/Vista is no longer supported but the last release version 49 is available.
Similar/alternative apps: Chromium Portable, Google Chrome Portable
What's new?
  • Several minor improvements.
  • Several API improvements.
  • Bug-/Security fixes.

Yes Google Chrome has a more catchier name but do they offer a portable version of their software, I think not.

notanon752 2008-12-31 15:35

Try this site for portable google chrome:

I kinda prefer to use this IRON for some reason. Just don't like using google, they tend to secretly archive and other nefarious unAmerican stuff.

(What software is this website using to do this "Post your Comment" module? I have website and want to implement something similar. Please share the good stuff.)

Rokth 2009-01-02 07:44

only supports ssl 2.0
I see no reason to use it

ThomasAlan 2009-01-02 15:23

I see no reason to use it, if you want privacy simply use UnChrome and you can't use custom themes with it.

Opsimathic 2009-01-03 09:29

If I am not mistaken, UnChrome appears to work on the installed version of GoogleChrome and not the portable version. IRON therefore retains a certain level of useful utility.

halnine 2009-01-03 23:22

Iron also has a preliminary implementation of AdBlock, which is its greatest advantage (not specified in main post).
For that reason only, it's now my default browser (although my MAIN browser is still Firefox).

mhack 2009-01-06 18:06

"Good Artists COPY, Great Artists STEAL"

I have used Google Chrome and I like the way how they make the interface different from the conventional browser and I also like the Task Manager, a new to web browsers.

Then there was IRON with all the nice features of Chrome but without the negative one, the privacy issue. With add-ons/extensions soon to come, I think this will be a good contender to FireFox in time.

sabwab 2009-01-09 04:03

why would u use open software from small group off people as opposed to the Google software thats under critisism and survaillance.. and such?

Midas 2009-01-10 13:53

Because it the exactly the same code re-factored to extirpate the privacy compromising features?

Axel 2009-03-31 08:52

SSL fixed, Themes are working, too (some at least) - still the better alternative to Chrome, IMHO

Jake 2009-05-21 14:01

New version (v2.0.178.0 released on May 17, 2009) is faster and a lot of bugs have been fixed. If you like Google Chrome, SRWare Iron is definitely worth a look. This browser is slowly but surely (quit calling me Shirley!) becoming my primary browser.

Zeus 2009-06-27 06:30

This baby is FAST!!

Donald 2009-09-16 13:48

Chrome Plugins for Iron are available at
Not many yet but I am sure more will arrive.
Please contact the AdBlock Plus people and see if they can make ADBLOCK PLUS extention for Iron

freakazoid 2009-11-14 20:01

I've updated the listing for Iron, but for those of you who are adventurous, there's a new 4.0 beta available:

the accountant 2010-01-02 11:22

you can copy and paste bookmarks between different versions or different machines instead of syncing. Also use to get more privacy as search logs are not retained longer than 24 hours. Its different to google but has refining options. Now Iron has a lot more extensions such as invisblehand and we can kiss Firehog 3 goodbye.

freakazoid 2010-01-03 02:15

Iron 4.0.275 RC available here:

When official 4.0 release is announced, this listing will be updated.

helg 2010-01-05 11:15

since firefox poratble is blocked by my employer (providing me only IE 5 or 6 and he didn't think to block Ironkey this is the most advanced browser to my disposal.

Triton 2010-01-08 12:51

I'm using the most recent beta release 4.0.275, and it works just like Chrome. I copied my settings and extensions from the Chrome folder to this one, and it has worked fine, if not better than Chrome, ever since. It loads the themes and extensions from the main chrome site as well. It's basically Google Chrome Portable, but without the privacy issues.

Terrine 2010-02-03 07:44

I've been using this for ages and it just keeps getting better!

ScrewGoogle 2010-02-07 20:14

As open as Chrome is, it's still mainly develop by google themselves. They are a bunch of spy-ware. SRW Iron is the way to go. It include ad block, instead of the shitty ad hides extension that chrome has. Chrome will never be able to block's google policy.

thINC 2010-05-27 00:21

I like chrome... I like firefox...
Chrome is faster & no clutter on the top of the screen...
Chrome does offer the "incognito" window, which I like..
Now if SRWare is everything y'all are raving about... It sounds good. I'll try it. If it's good... Maybe I'll be back to let you know...

cerra 2010-06-26 14:18

How do I do this?

Add iron/complete/adblock.ini" target="_blank" target="_blank">adblock.ini to the "Iron" program folder to block malicious ad servers.

Kow 2010-10-26 21:42

portable app loaders for browsers suck.. if you make this your default browser, you get a different set of settings depending whether you launch the browser from the launcher or the operating system launches the browser (from the default browser exe in the registry)

Smudgy 2010-10-29 21:46

SRWare Iron Can't Be Trusted - At Least Not Yet!

They've developed a so called privacy oriented browser that played on the paranoia of the general public for ad revenue as their prerogative all along.

Did you know what the developer was quoted as saying? Google is Evil and the German people don't like Google, well cool I'm not bothered with that, that's all cool, I don't personally trust Google either.

Then what else do they now do, run Google Adsense on their site and support running Google banners on their startpage site also.

Look, you call Google evil then you are seen supporting Google, what is that telling us? I'll tell you, one big mixed bag of messages that should make you think real hard.

So can this developer really be trusted and should we really support SRWare Iron.

Well one thing is certain, until this developer starts flying right and shows us some of these true colors of mistrust towards Google, then it's looking really fishy and this is all the real truth around here about this SRWARE Iron! :(

Go research it and see for yourself!


r 2010-10-31 01:59

Change the startpage if it bothers you.

Chaolin 2010-12-03 17:19

Sometimes the up/down arrows on rightmost scrollbar disappears, and after a while radio buttons and checkmarks on forms also disappear. Great AdBlock system with the blacklist!!! And it renders pages fast. I hope the bugs are fixed real fast.

Potanin 2010-12-27 23:04

I f someone wants to temporarily disable adblock.ini, what's the procedure?

guinness 2010-12-29 12:05

Rename it!

freakazoid 2011-01-03 07:58

One thing I don't like about Iron is their insistence on using for their extensions URL. Why not use the official Chrome extensions URL?

Disgruntled Grizzly Bear 2011-02-09 03:03

If we don't want another niche browser, someone tell these guys/this person..

- to host the source code on,, or Google Code (instead hosting 3 zip files on *puke*

- to use the official chrome website for extensions

- to change the name from something less memorable like SRWare Iron to something like "Chrome stripped of privacy invading features"

- to reflect program version with official chrome builds, it's at 8.x while chrome is climbing up to versions 9.x and 10.x

- maybe push chromium developers to care a little more about users privacy thus eliminating the need for SRWare Iron.

Unless we check the thousands of lines of source code every time a new version is released, how do we know their not slipping in their own backdoor?

What happens if SRWare Iron inherits a critical vulnerability from chrome that is being exploited in the wild, will the developers find the time to update in a similar fashion as the chrome developers would?

- from one Disgruntled Grizzly Bear to another.

question 2011-02-19 19:05

does iron support html 5 like the newest version of chrome?


TEX4S 2011-03-30 07:25

Uhhh... I thought SRIron was proved to be absolute ripoffware a long time ago... guess this site didnt get the memo :)


stoned 2011-04-08 10:43

Wow, I love this Browser!!
It's fast, stable and if you want a privacy safe browsing SRW Iron is the way to go. It include a clever ad-block list (you can reach newest updates here:
Iron rocks!!
For Italian Users: If you want you can find here:
an alternative 100% portable (instead of original SRW Iron, it cleans also some small registry footprints).


webfork 2011-04-08 17:53

Stoned: thanks, added X-Iron mention to the program description.


123 2011-04-13 12:10

"Chrome stripped of privacy invading features"
'CleanedChrome'? 'LessEevulChrome'?


carbonize 2011-04-13 13:46

Yes but you could just use AdBlock Plus for Chrome and then you get a selection of lists to choose from.


freakazoid 2011-10-13 17:55

I am taking this off my favorites list.

Iron is simply Chromium recompiled with a few things added:

Some other sources to read:


Erkhyan 2011-11-07 09:04

If Iron is just Chromium with a few things added, I think I'd still choose Iron for a non-portable use, at least until Chromium binaries for Windows become readily available (I'm tired of being redirected to Chrome every single time I try).


freakazoid 2011-11-07 19:58

@erkhyan: You could try Chromium Portable:


Erkhyan 2011-11-07 20:12

I knew about Chromium Portable, but that wasn't the problem for me: while Chrome, Chromium and SRWare Iron are now all available in portable versions, only Chrome and SRI have easily found installers for use as a main browser.


freakazoid 2011-11-07 22:11

Gotcha! Misunderstood your comment. After all, this site is about portable freeware ;)


Ruby 2011-11-11 08:03

@Erkhyan: Chromium binaries -

Choose the Latest folder XXXX/ and then there's also a mini-installer

To run portably, pass this on the command line [ --user-data-dir=.\ ] (without the brackets)


mrpink 2011-12-20 11:37

Iron does not create any registry keys anymore


mrpink 2011-12-22 14:52

Can someone else confirm this? Iron not only does not leave behind any registry keys, but it doesn't touch the registry at any time


megabyte 2012-01-21 04:55

For those who choose Iron over Chrome, there is no need to be without the built in PDF reader. If all you desire is simple PDF reading, and not things that other PDF readers (SumatraPDF, etc) afford you, then find yourself a copy of pdf.dll (I got it from D/L and “installing” Chrome Portable – and put it in the same directory as iron.exe. A restart may be in order, also a visit to chrome://plugins may be required to enable it after chrome restart.


mrpink 2012-04-03 20:03

Again , Iron is stealth. It doesn't touch the registry enen if you run directly iron.exe (and not ironportable.exe)


bankr 2013-01-25 05:18

Please fix someone: "To block malicious ad servers, add adblock.ini to the "Iron" program folder"

Adblock.ini is in the Iron folder by default and Iron crashes w/o that file (at least on my XPProSP3 - yes I stil use XP :).

"Potanin (2010-12-27 23:04): If someone wants to temporarily disable adblock.ini, what's the procedure?
guinness (2010-12-29 12:05): Rename it!"

Renaming adblock.ini apparently will crash Iron. Clearing it is the only way I know to disable it.


Gemini Apollo Gomez 2013-04-21 18:02

The link to adblock.ini is broken in the paragraph,
"To block malicious ad servers, add adblock.ini to the "Iron" program folder."
and gives a "404 Not Found" page as of 04/21/2012.
Extracting places an empty adblock.ini in the Iron folder.
On SRwares web site adblock.ini is at but is dated 05/16/2012.
The SRwares forum at
provides several work-arounds, including links to files necessary to create a customized adblock.ini as follows.

Opera urlfilter.ini is available here:

Here is a VBScript to make the changes from Opera urlfilter.ini to Iron adblock.ini

Here is the Updated 24 Jan 2013 Fanboy Main List with Stat/Tracking Sites converted to Srware Iron adblock.ini format:


freakazoid 2013-05-31 23:48


bankr 2013-09-16 10:32

@freakazoid: The ONLY real reason to use Iron instead of Chrome/Chromium/etc is its native portability and native adblock.ini. That's all.
Maybe there is smth that AdBlock plugin can do that I can't get by editing Iron's adblock.ini?
And for heavy Opera users (like me) it's easy just to copy urlfilter.ini. Without asterisks, of course.


freakazoid 2013-09-16 20:49

As of Chromium 17, the web request API makes adblocking addons like Adblock Plus more sophisticated than using Iron's adblock.ini.

Iron's adblock.ini is less sophisticated than Opera's urlfilter.ini.

The only positive is Iron's adblock.ini probably takes up less memory than using an adblocking addon.

I tried to update to SRWare Iron Portable 39.0.2100.0 and it erased all my security and privacy extensions. (OneClick Cleaner, ZenMate, Netcraft, WOT, TrafficLight, Blur, Ghostery, Adblock Plus) It also erased all my bookmarks. I'm sticking with my current version of 38.0.2050.0.

Fixitman 2015-10-17 05:48

version 45: No flash support whatsoever. It also disables all but a two plugins. I understand this is a security issue, however, if you do need Flash, this is not the browser for you. You cannot add Flash support to version 45 of Iron. The former plug-ins do not work, and the latest download which would be supported in Iron contains malware, checked by over 40 different engines and cannot be installed if you have ANY anti-malware engine running. If you don't, be aware you're installing malware. If you have no need for Flash or most other browser plug-ins, feel free, you'll be secure (but missing quite a bit of content.)

Alternatives: Do not update to 45. Install 43, which still supports the (old) flash players (be they however insecure.)
Chrome itself has a built in alternative to Flash in the latest version. Maybe someone will figure out how to "port" this to Iron without doing a bunch of stuff in file explorers etc.
Note: trying to install the latest Adobe Flash for Firefox crashed my XP system, XP is basically no longer supported with version 19. the latest update to Flash 18 works, however.
I have Flash disabled on all but two sites which use the older version just fine.


random17 2016-08-07 14:16

Just noting that Iron Portable and SRWare Iron Portable, as well as GoogleChromePortable and X-Chromium, create these registry keys:



Also note that the HKLM key is hidden in regedit. I can see it being created using Regshot and get to it and delete it with an alternate registry editor. I don't know how the key is protected. (Any info appreciated.)

The only Chromium browser that doesn't create these keys is Chromium Portable (

They also create the following folders/files:

C:\Users\*\AppData\Local\Chromium\User Data
C:\Users\*\AppData\Local\Chromium\User Data\Crashpad
C:\Users\*\AppData\Local\Chromium\User Data\Crashpad\metadata
C:\Users\*\AppData\Local\Chromium\User Data\Crashpad\reports
C:\Users\*\AppData\Local\Chromium\User Data\Crashpad\settings.dat

random17: thanks for the info but, as that addresses multiple programs and not just Iron, posts like that really belong in forums.
