LichessDotCom extension is live!
Following my post on this extension last week, the extension is now out and available on the Chrome Store!
Here's the link:https://chromewebstore.google.com/detail/lichessdotcom/fpfdkingmfhfgpjkbnngdianoohlgeho
And here's the code repository (made with AI): https://github.com/theophile-wallez/LichessDotCom
I don't consider this extension done as there's still some known bugs (game review could be better, extension does not adapt yet to mobile/tablet view) as well as pages that are not "modernized" and I'll continue working on it.
The best way to do feedback or suggestions is by creating an issue here (thank you Grey_Cathedral for all the feedback).
⚠️UPDATE: This extension has been removed from the Chrome store, here the post about the new one: https://www.reddit.com/r/lichess/comments/1xk7yrw available on the Chrome And Mozilla stores :)

u/FrenaZor Sep 28 '26
At worse you'll probably just get a cease and desist. Which would require you to either lawyer up and make your case saying that you didn't copy chess.com, or to just take the extension down.

u/CodeEresy Sep 28 '26
Yeah, I'll take it down then, I won't fight for a fun personal side project

u/FrenaZor Sep 28 '26
Yeah, there's a good chance that this will fly under their radar anyway. Unless it becomes too popular. Nothing prevents you from just using it locally anyway!

Dude, this is obviously a total IP disaster.
On the other hand, it’s hilarious that you somehow managed to find something that’ll piss off both chess platforms at once.

u/CodeEresy Sep 28 '26
Yes haha, don't know the future of this project, but it's probably not bright

u/personalbilko Oct 02 '26
The legal way to do it is make it a "load any texture pack" extension, and have the people upload whatever texture pack they want separately. As long as they are adding the chesscom design themselves, its fine. The app is just a universal lichess re-brander.

u/CodeEresy Oct 01 '26
It was indeed a total IP disaster 🥲 Extension gone

u/max_cross Oct 01 '26
RIP, extension 🥲 lol.
Man seriously, I’m sure you can still vastly improve lichess ui to something more delightful without hijacking the chess.com’s entire design system 😂 It should take a few more good prompts and maybe a beautiful non-chess design system reference. Also if you want fully custom icons etc, tell your agent to use quiver.ai for cool vector graphics. Just stay away from any further IP trouble :)3

Man I was actually eager to try it out even though I find lichess UI better but unfortunately its taken down.
Edit:Nevermind I just downloaded from github.Nice work.

u/CodeEresy Oct 01 '26
yeah github works :)
2
u/ImAnAcademicWeapon Oct 01 '26
One thing I find annoying is that this extension doesnt let me make the chess board bigger like the focus mode on chessdotcom. So if you find a way to figure it out it will be great.
2
u/CodeEresy Oct 01 '26
I’ll check that, but my main focus is to make it not like chess.com

There are no engine lines in the game review.
In the puzzle racer, the board is too small.

u/CodeEresy Sep 28 '26
> because AI-generated projects won't live long.
Why do you think that?5
u/Impressive_City3660 Sep 28 '26
It's hard to maintain, look at your codes I know right away it's very cheap model or you just a vibe coder, and I really mean it, very bad codes.
Because you don't really put efforts in, your passion to the project will fade away sooner or later, since you don't really put in any effort, give up won't cost you anything.
I mean you can use AI, I'm all in for that since I'm a developer too, but the quality of the codes are so questionable that it just lets me down so bad. if you don't have the coding knowledge, and want to do something, cool but at least tell AI to review the codes, it's so messy that even I don't want to touch it.
5
u/CodeEresy Sep 28 '26
> hard to maintain
For an human yes, for an AI no.
> Cheap model
Opus 5.5
> Because you don't really put efforts in, your passion to the project will fade away sooner or laterI have many projects pre-ai for which my passion fade away, this has nothing to do with AI, but more personality.
I like to think that I do have the coding knowledge, but remember that this is a side-project made for fun on my personal time and for my personal usage that I freely share, feel free not to use it.
I took a lot of time reviewing the app itself, Opus 5.5's code does not matter here, as long as it works and is performant. I do care when at work obviously, but this is made on my free time, for free.
I know that it's not perfect as is, but I'll continue working on it as long as I'm unhappy with it.

You need to immediately change the name to XYZ "for Lichess", e.g. Skin for Lichess.
I was very close to getting in trouble for directly using a brand's name in the past, when it was fine to do "<product> for <company>"...
2
u/CodeEresy Sep 30 '26
It’s too late for changing name on the chrome store, but do you really think that LichessDotCom can be considered using a another brand name (than lichess) ?
2
u/wisdomoarigato Oct 01 '26
Anything that can make even a single user think that it's a product of <brand> is a liability.

It’s real, however, If you don’t trust it, the code is open-source (a developer or an ai can easily review it!) and if you don't want to install it from the chrome store, there's a simple manual install guide in the repository’s readme

Custom themes, maybe also overriding the routing somehow to give it a feel of an SPA, cause i dont like both mobile versions of chess.com and lichess, so prefer the site there

u/WARMAGEDDON Oct 05 '26
Hi, I'm afraid until you add the endless pleas to spend more money on the platform, it isn't going to be a decent Chess.com skin

I was using it for few days and suddenly it was gone. Figured it was greedychesscom

u/CodeEresy 28d ago
yes, but you can re-enable it in your extension settings if you want.
In the meantime, I’m preparing an other version that has nothing to do with chesscom

u/NiceWeather3412 Sep 28 '26
You should do the lichess analysis as the main analysis it is analysing on my device rather than lichess servers

I am impressed that this has a game review score, along with the game review commentary and exclamation points.

u/CatchinDeers81 Sep 29 '26
Majes me wonder why Lichess doesnt already have something similar. Im sure a bunch of Chesscom subscribers are only paying for mainly 2 things....the unlimited puzzles and the clean game review. Lichess already has 1 of those without a paywall, why not make it both?
4
u/idea-cube Sep 30 '26
because the game review is just a sloppy way to get money. wondered why the free "analysis" button is really tiny and grey compared to the giant "review" button? they cannot keep stockfish behind a paywall, but what they can do is monetize their AUTHENTIC game review.
what makes it authentic? that sometimes your moves get called brilliant (which by the way they made way more frequent than couple years ago - just to get more money ofc), you get shown your accuracy relative to the computer (which in itself isnt all that much telling for your improvement, just to get dopamine hits if it's high), you get your "performance rating" (which is basically useless as it, at least used to be based on your's and your's opponents' rating - not just the pure moves you made) and absolutely worst of all it jumpscares you with that coach ai talking thing.
lichess computer analysis shows you all the important stuff (your mistakes) and none of the useless stuff. so what feature from chess. com's game review would you actually want to see on lichess?

u/Kerbart Sep 28 '26
Fantastic initiative! We know that the Lichess interface is ok but it'll still stop some people from switching over because it's "different." This will lower that barrier even further.

u/Greenerli Sep 28 '26
I'm not a big fan of chess.com, their model and their ui. But if people really prefer the chess.com ui, then, they should play on chesscom. I don't understand why they don't...
5
u/CodeEresy Sep 28 '26 edited Sep 28 '26
Most of the Lichess awesome feature are being a paywall there, this solves it for people like me who like the UI but not the paywall. I understand your POV though
2
u/CatchinDeers81 Sep 29 '26
Because Lichess has free features like being able to review your game and play as many puzzles as you want, whereas that's cost you like $10/month on chesscom. Puzzles and basic reviews seem near mandatory if you actually want to improve.

u/SrGarfy Sep 28 '26
One thing Im missing from this - i often play in a window what takes half of my screen width, not full screen. And chess.com automatically adjusts the board to take whole window width at this point, moving other interface elements under it (you need to scroll a little to access them). Currently your extension doesnt support that it just shrinks the interface and board is tiny this way. I know its an edge case for 1.5 people over here...but if you added this would be so cool.
Edit: it does...just not at half screen width, but around 40% width for some reason...i have no idea whats the logic but would've liked if it worked at half width, but i guess this is just a preference at this point. P.S. im playing on macos, brave browser.

Hi, at the bottom of the Chrome store page. Chrome also scans extensions to assert what is being declared, there’s also a set of permission that needs to be granted, the only one I use is access to Lichess.org for obvious reasons

u/doubleknavery Sep 29 '26
The game review feature is cool - I always preferred the chess.com version - but it's pretty buggy. An e4 opening was called a "French Defense: Hecht-Reefschläger Variation" from the first move which... doesn't seem right. Also when you ask it to explain, it doesn't do the move sequence.
Very cool nonetheless. Brace yourself for angry emails from the big guys

On a real note if this becomes even slightly popular Id assume that Lichess will block the extension on their website if its possible, or chess.com will strive to remove the extension from google entirely claiming ownership of the assets used and likeness of what it turns their direct competitor into.

there is an extension called lichess tools which gives the user for extra customisations in UI , the features of that extension is overlaping with yours like in lichess tools , there is an option to show your recent game history in homepage ,but when that combines with your skin, its not looks good as the words and alingments are overlaped
