So it's been about a month since we released the Rebrickable v3 "update". I thought I'd write a quick post to bring everyone up to speed with what has happened in that month.


After the initial release, there were significant performance problems that were not revealed during testing. With some hardware upgrades and weeks of performance tuning work it is now running much better. There are still some timeouts occuring when viewing huge lists of items or trying to import massive files, but I will continue working on improving things.

To assist me with improving performance, if you have a file you are trying to import but keep getting 504 timeout errors please send me your file so I can test with it.


I won't even try to list all the changes that have been made, but my git repository tells me I have made 400 commits since release.

If you are still encountering errors, please use the Bugs Forum to report them. I do get automated error emails for some things, but not everything and emails are easily overlooked when I get thousands per day.

Next Steps

There are still plenty of fixes I need to put in place to improve performance and stability, but the major problems have been fixed. Next, I will start to focus more on improving the usability of some problem areas and add some of the features I really wanted to add but missed the v3.0 cut.

    I have found some of the changes in Rebrickable V3 are great, but one thing I miss is the random MOCs section on the home page, it would be great if you brought that back.

    Great work, I have gotten used to the new site and I like it a lot. Are you going to release the Pro Plans any time soon?

    Awesome site!
    It got me digging out my old lego and has got my kids into it as well (if I'm not hogging it all for myself!)
    Thankyou for all your hard work.

    Love your site!!! Just love it. Absolutely great, the biggest in Lego for sure!

    Question. (Maybe it has already been updated, or maybe it has been asked by others as well, I'm not sure..., but in case of that: sorry for asking)
    Would it be possible, in case of an correction in set inventory, to automaticly inform set owners there has been a correction to their set?

    Let me add my voice to the chorus of others; thank you for your excellent work on Rebrickable!  The 3.0 version of the website is outstanding, and sometimes it's hard for me to believe that this is a free site.  Well done!

  • 2 years, 11 months ago Eolindel Level 8
    A huge thanks as well. Rebrickable definitely makes some things possible while it wouldn't be without it.

    Took me a while to get used to the new interface (being autistic doesn't help), but I love the new design and features.

    What most people don't see: The admin-section has been made much better and easier to use. Now we can keep better track of all change request and other input from users, which helps us to improve the database and keep it up-to-date.

    Just wanted to say a huge thank you for all your work which must be an awful lot!! As a disabled lady I find your system incredibly useful for organising my sets but more importantly my bricks. Without your site it would be a lot harder for me to build and I simply wouldn't be able to do as much. Thank you very much.
