  • Construct 3 works best in the browser. However if you need to preview or debug your project with NW.js features active, you can also use Construct 3 as a desktop app based on NW.js.

    Download links

    Stable release:

    Beta release:

    There's also a tool to use Remote Preview for NW.js:

    How to use it

    The following instructions apply for all three links above:

    1. Download the appropriate package file listed above.
    2. Download the version of NW.js you want to use from Note: We recommend downloading the 'SDK' version because it provides the browser dev tools, which are useful for development. The 'Normal' version does not include dev tools.
    3. Extract both the package file and a version of NW.js to the same folder (so both nw.exe and package.json are the same folder).
    4. Run nw.exe. You may need to approve a security prompt, or wait for an antivirus scan.

    Construct 3 in this mode will be the same as you see in the Chrome browser. However when you preview or debug, the features of the NW.js object will work, since it's running in NW.js.

    Remote Preview for NW.js

    Remote Preview for NW.js will load in NW.js. This works the same as it does in the Chrome browser, but once again the features of the NW.js object will work since it's running in NW.js. This can be useful for previewing with NW.js features when the editor is running in a browser.


  • Let's see...current memory usage...

    Running C3 in Chrome (with no other tabs open).......667 mb

    Running C3 desktop build beta......................................157 mb

    Yeah, I know what I'm using from now on.

  • Lancifer - if I try comparing the memory usage and leave them idle for a minute (so they garbage collect/compact memory etc), then the difference is only about 50mb (~190mb vs ~240mb). I mean, they use the same browser engine, so it's expected their memory usage would be similar.

    If you have a browser addon that wastes tons of memory, that could explain the difference, but that's the addon, not Chrome. (I've seen some ad blockers can waste hundreds of megabytes of RAM!)

  • Chromes not known for being light on its feet.

    Of course that does beg the question of why use it as the default.

  • Ashley

    Right, I understand that. But, I shouldn't be expected to have to disable my addons every time I use C3. I do appreciate the effort in giving us an alternative, though. Thanks.

  • Thank you! I was waiting for this

  • Thanks! Looking forward to using this for source control (I use bitbucket / git). Just last week I lost a day of work due to a user (i.e. me) cloud save / local *.c3p mixup that source control could have saved for me.

    I do still like the browser option of working anywhere I have chrome, so will still use that sometimes too.

  • Nice job guys, looking good. Will get in and do some testing in the near future.

  • Yes! Project saves. Now every time I save, it doesn't resave the ~1GB of video I'm currently using. Thanks!

    Edit: FYI I spent 30 mins making some changes, saved it as a project, tried to open it again and the app crashes. No error code or message.

  • Great upgrade to Construct 3 !

    The next step should be a permanent purchase option for those who can't stand subscription model.

    I hope to see this coming, for now... I'll have to use other options.

    Anyway, keep up the good job! it's looking great so far.

  • Try Construct 3

  • Oh wow, finally a desktop build.

    Thanks a lot Ashley, I've been waiting for this.

    Also, I agreed with Alon. Please also include a one-time license model, subscription models aren't really good for some companies/developers.

  • Great, thank you! ๐ŸŽˆ๐Ÿ˜ƒ ๐ŸŽˆ

  • Well done! thanks

  • Wow! Nice Work!

    Now i get 1/2GB RAM free....

    I know its use the same engine.... but i have addons and other things on my Chrome Browser making alot of RAM used for anything, now with this version of C3 i using only 100- MB

    Keep the Awesome work!
