🏠
Join home WiFi

Enter your home network details so friends can join easily from anywhere.

🌐
Use its hotspot

Connect directly to the board's own WiFi network for quick local play.

5
🎮 Jump into the game

Open Minecraft 1.16.5 on your device, type in the board's address, and watch your procedurally generated world load up.

6
👥 Play with friends

Invite up to 3 friends to join, break blocks, chat, and craft together on your mini server.

✨ Tiny server triumph

You now have a working Minecraft server on a microcontroller, proving games can run anywhere with creativity.

AI-Generated Review

What is macerun?

Macerun runs a bare-metal Minecraft 1.16.5 server on the ESP32-S3 microcontroller using C and ESP-IDF. It handles up to four players with procedural world generation, block breaking and placement, basic physics, chat, and a /give command for items. Developers get a tiny, WiFi-enabled server that persists changes to non-volatile storage—no OS, just raw sockets and protocol handling for that maze runner thrill on constrained hardware.

Why is it gaining traction?

This bare-metal embedded C programming GitHub project stands out by squeezing a full Minecraft protocol (v754) onto a microcontroller with 16MB flash and SPIRAM, inspired by similar bare metal GitHub experiments like those for Raspberry Pi or NRF Connect SDK. Users notice smooth chunk loading in a 2-chunk view distance, multiplayer entity tracking, and on-the-fly terrain with biomes, trees, and caves—perfect for proving embedded limits without Java bloat. The hook? Turning "impossible" into playable, like a maze runner sequel on silicon.

Who should use this?

Embedded engineers experimenting with bare metal programming GitHub repos, IoT hobbyists building Minecraft bare metal servers, or C devs seeking a maze runner-style challenge on ESP32-S3. Ideal for demos at maker fairs, teaching network protocols on tiny hardware, or just running a private maze runner stream with friends over WiFi AP/STA.

Verdict

Fun proof-of-concept for bare metal OS GitHub fans, but with 12 stars and 1.0% credibility score, it's raw—expect bugs, no mobs or chests yet, and docs limited to README. Fork and tweak if you're into extreme constraints; skip for anything production-like.
