Redditor Releases Jet Studio, a Godot-Style ESP32 Editor
The free tool lets developers build and flash 2D and 3D games directly to the ESP32-S3 microcontroller.
Updated on Nov. 1, 2026 in Gaming
A Reddit user released Jet Studio, a Godot-like game editor designed for the Arduino Nano ESP32 with an ILI9341 SPI display. The editor lets users build and flash 2D and 3D games to the ESP32-S3.
Why it matters
Jet Studio brings a familiar, Godot-style workflow to microcontroller hobbyists, lowering the barrier to building games for small embedded hardware. It was shared through the ESP32 subreddit, where hobbyists experiment with low-cost chips.
Demos reported by the developer show a 2D shooter at about 85 FPS, an Outrun-style racer at 65 FPS, and a 3D physics demo at 55 FPS. The source does not specify the measurement method or hardware conditions behind these figures.

The details
Jet Studio includes a scene tree, Inspector, 2D and 3D views, and a script editor, along with Godot-style signals, tweens, and an AnimationPlayer with a timeline. Users build the game on a PC and deploy the finished game to the ESP32, using PlatformIO and ESP-IDF for build and flash functions. The editor also includes a serial monitor and a RAM estimate before building.
Culture Shift
Jet Studio applies the scene tree, Inspector, and signal-based workflow popularized by the open-source Godot Engine to the ESP32-S3 microcontroller. It reflects a broader hobbyist trend of bringing desktop game development conventions to inexpensive embedded hardware.
Hobbyists with an ESP32-S3 and a compatible display can build and flash 2D and 3D games from a PC without learning a new engine from scratch. The editor's serial monitor and RAM estimate help users check whether a project will fit on the device before flashing.
The takeaway
Developers interested in microcontroller game development can experiment with Jet Studio's editor and its built-in RAM estimate to plan projects that fit within the ESP32-S3's limits. Checking the frame rate of each demo against the target display before scaling up a project is a practical starting point.
