The author says the project took one month and was built with substantial AI assistance. Those details come from nefu-dev’s October 2, 2026 DEV Community post; they are project claims, not independently verified results.
What nefuOS is meant to include
Rather than describing a kernel alone, nefu-dev presents nefuOS as a collection of operating-system components. The names and capabilities below are the author’s descriptions in the October 2, 2026 DEV Community post; the linked repository and the software itself were not independently inspected.
- Ncore: a custom kernel that the author says boots through BIOS using El Torito and through UEFI using GRUB multiboot2.
- Nbrower: spelled this way in the post, a custom browser reported to support HTML, CSS, JavaScript and WebGL2, with its own TLS 1.3 stack.
- nefucpp: a compiler from C++ to the project’s
.nefudformat. - NPKG: an HTTPS package manager described as installing packages in a .deb-style format.
- Nshell: a shell with more than 60 Unix-like commands.
- Ngame: 34 built-in games.
- NAI: a fine-tuned Qwen2.5-1.5B model that the author says can call tools, including writing files and running commands.
The post also lists a Chinese input method, TTF font rendering and 107 built-in apps. These are advertised project capabilities; the post does not establish how well they work or what hardware they require.
What the browser and WebGL claims mean
The browser is one of nefuOS’s most ambitious claimed components. Supporting HTML, CSS and JavaScript involves more than displaying static pages, while WebGL2 adds a graphics interface commonly used for interactive 3D and other GPU-style rendering in the browser. The post does not provide standards test results or a measured compatibility level, so the feature list should not be read as evidence that arbitrary modern websites or WebGL applications work.

- Raspberry Pi 5 with 8GB RAM: Model SC1112 featuring a quad-core ARM Cortex-A76 processor running at 2.4GHz. Enhanced Connectivity: Includes dual 4K micro HDMI ports, USB-C power input, and high-speed USB 3.0 ports. PCIe Expansion Support: FPC connector enables M.2 NVMe SSDs when using compatible adapters. Fast Storage Options: Works with microSD cards for booting, or optional NVMe storage for advanced projects. Built for Projects & Learning: Ideal for programming, home labs, DIY electronics, automation, and Linux-based development.
According to the author, nefuOS uses SWGL, a software GL implementation of about 9,000 lines, to provide WebGL2 without a GPU driver. That is a notable design choice: software rendering can avoid reliance on a supported graphics driver, but it is not equivalent to demonstrating hardware-accelerated performance. The post gives no benchmark or supported-device list.
The author says the browser has its own TLS 1.3 stack, the protocol used to secure many web connections. They also identify browser work that remains incomplete: better CSS support, including flexbox and descendant selectors, and fully wired DeepSeek login. Those acknowledged gaps are important context for the broader browser feature claims.

- Compact Design with Flexible Integration (No Header): Compact ESP32-S3 mini development board without pre-soldered pin headers, allowing direct soldering or custom PCB integration for embedded system design and space-limited applications.
How the author says one month of development worked
Neffu-dev describes a solo, AI-assisted process. The author says they hand-wrote the first approximately 120,000 lines for the kernel, virtual file system (VFS), inter-process communication (IPC) and core architecture, then used AI to fill in implementation details for roughly 80% of the remaining work.
The author reports approximately 215,000 self-developed lines—about 192,000 C/C++ and 24,000 Python—and approximately 1.04 million lines when third-party code is included. These are figures reported in the October 2, 2026 post, not independently audited counts. The post does not explain a counting method, and lines of code alone do not measure completeness, reliability or maintainability.

- If external power supply is required, just connect the + level of the external power supply to the position of 5V, GND connects to the negative terminal. (Support 3.3 ~ 6V power supply). Remember that when connecting the external power supply, you cannot access USB, USB and external power supply can only choose one.
The author summarizes their division of labor this way: “Architecture, decisions, and debugging are mine. AI just made the typing faster.” The account therefore presents AI as a major implementation aid after the author established the system’s core architecture, rather than as the project’s autonomous designer.
Challenges the author highlights
The post names several difficult parts of the work: supporting BIOS and UEFI boot paths, implementing TLS 1.3, resolving a QuickJS 2021 issue involving a second JS_Eval in the same runtime, and building SWGL. In a follow-up included with the post, the author says dual boot took the longest. They also describe the browser’s canvas pipeline for bloxd.io as the final piece needed before that game could render.
