OpenSpec offers a configurable specification workflow for teams and coding agents

Summary

OpenSpec is a lightweight, configurable framework for creating and managing software specifications. It is designed to help teams define what they want to build, refine requirements, validate that a specification describes the intended product, and verify that implementation matches it. The project positions specifications as a shared coordination layer for human developers and coding agents as work changes. Its documented workflow uses commands for exploring a problem and codebase, proposing a package of artifacts such as a proposal, specifications, design, and tasks, applying implementation tasks, verifying the result, and archiving completed changes. OpenSpec is open source under the MIT license and can be installed globally through npm, pnpm, bun, yarn, or nix. The site lists compatibility with a large directory of coding assistants, including Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode, Amazon Q Developer, Cline, Devin, Kimi Code, Qwen Code, and others. OpenSpec reports 68,000 GitHub stars, more than 265,000 developers using it each month, and one new specification created every two seconds. These adoption figures are presented by the project itself. The site also links to GitHub and Discord and identifies version 1.13.0.
