Sleepy Coder: a local assistant that finds the boring fixes in your code
This is a submission for the Hacktoberfest Open-Source AI Challenge: Slow and Steady . What I Built Sleepy Coder is a local coding assistant for the small, boring problems that pile up in side projects: the duplicate <h1> , the image without alt , the console.log you forgot, the TODO from three weeks ago. You point it at a folder on your computer and it: Finds tasks with rules (no AI, instant,…
This article highlights "Sleepy Coder", an open-source AI tool for finding and fixing small coding issues in side projects. The tool, created for the Hacktoberfest Slow and Steady challenge, identifies problems like duplicate HTML headings, missing alt text on images, forgotten console.log statements, and TODO/FIXME comments. It then provides clear instructions on how to fix each issue, including the exact file, line number, and code suggestions.
Sleepy Coder runs locally on a user's machine using Ollama, an open-source AI platform, and does not upload any code or data to external servers. The tool uses a local AI model, Gemma 3 4B, to analyze files and provide explanations for fixes. While an experimental feature allows the tool to automatically make changes, it is currently off by default due to issues with the AI model's editing capabilities.
Sleepy Coder is built using Astro with React islands and plain CSS, Fastify for a small API, SQLite for data storage, and Vitest for testing. The author emphasizes the importance of open innovation, as Sleepy Coder keeps all code on the user's machine, eliminating the need to share sensitive projects with external servers.
