Versions:
Harnest is an AI coding assistant configurator developed and published by Alex Gladkov, currently available at version 0.12.0, with two versions released in total, indicating an actively maintained but still early-stage project. The software addresses a practical challenge faced by developers who work with modern AI-assisted development tools: each AI coding assistant relies on its own configuration files, formats, and conventions, and manually creating and maintaining these configurations across multiple tools can be repetitive and error-prone. Harnest streamlines this process by generating configuration files for a range of popular AI coding assistants from a single, centralized tool. The configurator supports Claude Code, Cursor, Windsurf, Codex, OpenCode, and Qwen Code, covering several of the most widely adopted AI-powered coding environments and editors currently available. This broad compatibility makes Harnest relevant for developers who switch between assistants, teams that standardize on multiple tools, or individuals evaluating different AI coding solutions without wanting to rewrite their setup for each one. Typical use cases include bootstrapping a new project with ready-to-use assistant configurations, keeping instructions and settings consistent across tools, and reducing the onboarding friction associated with adopting a new AI assistant. Within a software catalog, Harnest falls into the developer tools category, more specifically the subcategory of configuration management and AI-assisted development utilities. It complements rather than replaces the AI assistants themselves, functioning as a supporting layer that prepares the environment in which those assistants operate. Its focus on configuration generation positions it as a productivity-oriented utility aimed at simplifying setup workflows. With its current release at version 0.12.0 and a total of two published versions, Harnest represents a young project under active development by Alex Gladkov, offering a specialized solution for developers who rely on multiple AI coding assistants in their day-to-day work.
