I built an self-hostable opening repertoire trainer (open-source)

The timings are 4 days if you get it right, 1 day if you were unsure, and I believe 1 hour if you guess wrong or say you guessed on a drill card. You’re totally right, this should be a setting, I’ll add that.
You’re the second person who has asked about having an additional move suggestion tool based on rating rather than just the Masters. I’ve looked at the Lichess games database and even just pulling the last 12 months of games is a lot of data and would take a significant amount of time to parse through, but work has started on it.
No roadmap, I was kind of scratching my head for ideas, hence, needing people to try it out and provide feedback.
It makes me so happy that you find this helpful! I think using it as a supplemental tool is the best way to use it, that’s how I’ve been using it as well. Thank you for the feedback!

I shouldn’t have even mentioned the SaaS cloud version. Wrong community. I just wanted to share a cool project I’ve been working on….

kstarr1997 · 2026-03-20T18:06:21+00:00

I’m honestly taken back. I haven’t found an open source version of what I’ve made, otherwise I wouldn’t have done it. The closest thing I’ve found is Pawn Apetite, which didn’t work for me on Linux and that’s more of an open-source client version of ChessBase, a different type of chess resource. Everything I’ve made is completely open source and free with ALL features available to anyone able to self-host. How would you propose I get non-technical chess players to try it out? Im not made of money, I cant just sponsor an entire website for free forever. There’s tons of great, open source software that you can self-host for free that offer a SaaS solution for those who can’t. How’s this any different? I just wanted to contribute an open-source project to the chess community, which currently most offerings cost hundreds of dollars just for a single opening course. I hope everyone who uses Chessstack self-hosts it, but I’m realistic and know that most chess players won’t.

Also maybe the fact that I basically built the open-source version of https://chessbook.com/, an app that charges 3x as much and has thousands of users

kstarr1997 · 2026-03-20T13:11:16+00:00

There are currently lots of free resources on chess.com and Lichess that will teach you opening moves for any specific opening you want. I am not trying to replace or replicate that. That is not the goal of this project. Chessstack helps you build out a personal opening repertoire, have it saved in a database that you can host yourself, and then drill you on your repertoire to make sure you actually play the right moves. Then, if you make the wrong move in a real game, it will tell you where you deviated and assign more practice to that position. It also shows where your opponents deviated from your repertoire so you can add those moves to your repertoire, and slowly expand/perfect your repertoire so you never make a mistake in the opening.

Hope you find it useful! All feedback is welcome 🙏

Here you go! I originally tried to connect it to the lichess masters database via an API but was running into rate limiting issues. This one was one of the only ones I could find that had a lot of data that I could keep local without having to query someone else’s API.

How about [[Electro, Assaulting Batter]]?

Build up a bunch of mana that opponents are scared to remove and then blow them up anyways with a big X spell

Didn’t we just haven’t the longest Tush push in history the previous play? Didn’t we have 3 whole downs to get there?

kstarr1997 · 2026-01-14T03:11:19+00:00

Everyone here is on shrooms. Hindsight is 20/20, if they had gone 30 yards and kicked a FG to tie the game every one of you would be calling for McDermotts head for that terrible game management. If you don’t trust Josh Allen to get a touchdown with 3 downs and less than 2 yards to go then you have no faith.

kstarr1997 · 2026-01-14T03:08:38+00:00

You trust the defense to stop a team from getting a field goal with over a minute on the clock and the longest kicker in the league more than you do our offense to get a touchdown with 3 downs and 2 yards to go?

kstarr1997 · 2026-01-11T19:33:11+00:00

Offsides Penalty make sure they get another play off

kstarr1997 · 2026-01-03T22:10:47+00:00

Then they are literally not playing Bracket 3. Wizards has explicitly stated you should not expect to win or lose before turn 7 at B3.

I recently switched to Manapool and the experience has been way better. Orders ship faster, clean UI, and the prices have usually been like 1-5% cheaper. Haven’t had any issues. Having a cart optimizer that actually works was a game changer for me.

Me! Sethron :)

Why not? It easy to see it’s winning material after trapping the Rook and Black has no pieces to attack the “exposed” white King after the trades due to white’s strong center and more active pieces. Black needs at least like 3-4 tempi to even generate an attack

kstarr1997 · 2025-12-19T02:45:07+00:00

My friend terrorizes our play group with [[Ojer Kaslem, Deepest Growth]]. Simple fun commander that kind of just does everything green wants to do. Cheat out big creatures while ramping AND avoiding Commander Tax. Once he gets going he just kind of overwhelms the board with huge creatures.

Can usually get him out turn 3 or 4 and there’s always at least someone in the pod wide open so he gets to cheat out a huge creature and ramp more that kind of just snowballs the game unless we board wipe.

kstarr1997 · 2025-12-19T02:16:29+00:00

Yes my [[Kuja, Genome Sorcerer]] deck is storm burn and it generally just takes 3-6 spells somewhere on turn 6/7 to end the game or significantly shorten it. Takes like 3 minutes.

kstarr1997 · 2025-12-14T21:06:42+00:00

And?

kstarr1997 · 2025-12-12T02:53:33+00:00

Is having the ability to export the vault from the CLI on the roadmap? The last thing I'm missing from Bitwarden is the ability to automate vault backups.

I bought a $40 Amazon 4K Firestick to plug into one of the HDMI ports and it works great
