Show HN: Rhun, an open-source code editor written in assembly (rhun.app)

The recent launch of Rhun, an open-source code editor crafted entirely in assembly language, is drawing attention within the AI/ML community due to its lightweight and efficient design. Rhun prioritizes performance by minimizing resource usage while still offering essential features such as tabs, syntax highlighting, fuzzy search, and optional Vim mode. This focus on efficiency allows developers to maintain high productivity without the overhead typically associated with more feature-rich editors. Rhun’s integration with AI capabilities is particularly noteworthy, enabling users to run builds and shell commands alongside their code while leveraging coding agents for assistance. Developers can also interact with their projects using Claude Code and Codex, either drafting commit messages or following AI sessions to enhance their coding experience. With 39 customizable themes, Rhun offers aesthetic flexibility alongside its technical prowess. This combination of lightweight architecture and optional AI features could lead to a shift in how developers approach coding environments, emphasizing speed and simplicity without sacrificing functionality.
