 Hi, I'm Belzedar. I run AtomicDB, a free public database that tries to do for atomic chess what tablebases did for endgames: work out, position by position, who wins and how.
</div>
<div>
 Where it stands today (18 October 2026):
</div>
<ul>
 <li>86.6 million positions stored, 16.5 million of them practically solved</li>
 <li>319 trillion engine nodes searched, all of it on computers donated by volunteers</li>
 <li>a free explorer and a public API that anyone can use: <a href="https://belzedar.duckdns.org/atomicdb" target="_blank" rel="nofollow noopener noreferrer"><a href="https://belzedar.duckdns.org/atomicdb/" target="_blank" class="" rel="nofollow noopener noreferrer">https://belzedar.duckdns.org/atomicdb/</a></a></li>
 <li>all the code is open source: <a href="https://github.com/Belzedar94/OpenBench" target="_blank" rel="nofollow noopener noreferrer"><a href="https://github.com/Belzedar94/OpenBench" target="_blank" class="" rel="nofollow noopener noreferrer">https://github.com/Belzedar94/OpenBench</a></a></li>
</ul>
<div>
 The volunteers bring the computing power. What nobody donates is the machine in the middle: the server that stores the tree, hands out the work and serves the website. I have been paying for that one myself.
</div>
<div>
 <br>
</div>
<div>
 Why I'm asking now
</div>
<div>
 The tree has outgrown that server. The database is 104 GB and grows by about 1 GB every day. In September the disk filled up and the whole project was down for five days. I bought extra storage to bring it back, and at today's pace the main disk will be full again in about two and a half weeks.
</div>
<div>
 <br>
</div>
<div>
 Memory is the other wall. The database indexes alone take 55 GB and the server has 16 GB, so the database spends much of its time waiting for the disk.
</div>
<div>
 <br>
</div>
<div>
 What the money pays for
</div>
<div>
 A server that fits the project: 64 GB of memory and two fast 1 TB disks, and room to keep growing after that.
</div>
<ul>
 <li>Server, 12 months: €1,290 (about €107 a month, VAT included)</li>
 <li>Backups stored away from that machine, 12 months: €46</li>
 <li>Payment fees charged by GoFundMe (2.9% + €0.25 per donation): about €80</li>
 <li>Room to grow: €584. The tree keeps growing, so this pays for more disk or a bigger machine when it's needed, or for more months on this one.</li>
</ul>
<div>
 Total: €2,000
</div>
<div>
 <br>
</div>
<div>
 No salaries and nothing for me. If we raise less, the first €200 already buys enough extra disk to keep the current server from filling up for another year, and everything above that goes towards the move.
</div>
<div>
 <br>
</div>
<div>
 I will post the invoices in the project's Discord so everyone can see where the money went.
</div>
<div>
 <br>
</div>
<div>
 If you play atomic, if you have ever looked a line up in the explorer, or if you just like the idea of a chess variant being solved in the open, this is what keeps it running.
</div>

<div>
 Thank you.
