It supports building scenes visually with sprites, tilemaps, particles and state machines, then flashing them to a chosen board. It runs at 60 FPS on ESP32-S3 and also works on desktop via SDL3 or headless. Hardware packages cover the LilyGO T-Deck Plus and T-Display S3 AMOLED, with CrowPanel Advanced 7″ ESP32-P4 support coming. The editor uses C++26 static reflection for inspector fields and is released under Apache 2.0. It was developed by Jairo Baldán, a game programmer from Spain, as a side project, and the author notes that most commits appear to be co-authored by Claude, so the project relies heavily on AI assistance. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Is there an open-source Unity-like game engine for ESP32 boards? Yes, Deki Engine is an open-source modular C++ game engine with a Unity-style visual editor for ESP32 platforms. It runs at 60 FPS on ESP32-S3, supports building scenes visually with sprites, tilemaps and state machines, and is released under the Apache 2.0 license on GitHub. It also runs on desktop via SDL3 or headless without a renderer. _Developers exploring ESP32 game tooling can track new embedded engine releases like this on daily.dev._ ### Which ESP32 boards does Deki Engine support? Deki Engine currently supports the LilyGO T-Deck Plus, with display, touch, keyboard, trackball, SD card, GPS and LoRa (SX1262), and the T-Display S3 AMOLED, apparently including the T-Display S3 Touch. Support for the Elecrow CrowPanel Advanced 7″ ESP32-P4 is planned, and additional packages cover software 3D rendering, IMU, RTC, I2S audio, Wi-Fi, BLE and a Tiled map importer. _Hobbyists picking ESP32 hardware for a game project can keep tabs on supported boards via daily.dev._ ## Similar posts on daily.dev - [An ESP32-S31-based modular development platform for AI-assisted hardware creation](https://daily.dev/posts/an-esp32-s31-based-modular-development-platform-for-ai-assisted-hardware-creation-qiwacviul) · CNX Software · 16 upvotes · 1 comments - [DS code editor & scriptable game engine](https://daily.dev/posts/ds-code-editor-scriptable-game-engine-hdfqkwbxq) · Hacker News · 1 upvotes · 0 comments - [This open-source OS for a 1.54" Waveshare ESP32-S3 ePaper display is the cutest thing I've seen this week](https://daily.dev/posts/this-open-source-os-for-a-1-54-waveshare-esp32-s3-epaper-display-is-the-cutest-thing-i-ve-seen-this-pd4g7oyxi) · XDA Developers · 1 upvotes · 0 comments - [CSS On The ESP32](https://daily.dev/posts/css-on-the-esp32-vmuqldabt) · Hackaday · 3 upvotes · 0 comments - [Open Source Stream Deck Targets Flexibility](https://daily.dev/posts/open-source-stream-deck-targets-flexibility-8swlbba0f) · Hackaday · 0 upvotes · 0 comments --- Tags: [#open-source](https://daily.dev/tags/open-source), [#game-development](https://daily.dev/tags/game-development), [#iot](https://daily.dev/tags/iot), [#embedded](https://daily.dev/tags/embedded), [#c++](https://daily.dev/tags/c++) [View this post on daily.dev](https://daily.dev/posts/deki-engine-esp32-gets-an-open-source-unity-style-editor-and-c-2d-game-engine-lugoeyzsb) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Deki Engine – ESP32 gets an open source Unity-style editor and C++ 2D game engine","url":"https://daily.dev/posts/deki-engine-esp32-gets-an-open-source-unity-style-editor-and-c-2d-game-engine-lugoeyzsb","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/deki-engine-esp32-gets-an-open-source-unity-style-editor-and-c-2d-game-engine-lugoeyzsb"},"datePublished":"2026-10-25T03:05:22.931Z","dateModified":"2026-10-26T00:00:18.023Z","description":"Deki Engine is an open-source C++ 2D game engine with a Unity-style visual editor for ESP32 microcontrollers.
