About
Emdash is an open-source agentic development environment that enables software developers to run and manage multiple AI coding agents from a centralized desktop application. The platform supports coding assistants such as Claude Code, OpenAI Codex, Cursor, Amp, and OpenCode through their command-line interfaces. Each development task operates in an isolated Git worktree, allowing agents to work on separate branches without interfering with one another. Emdash provides integrated terminals, code editing tools, application previews, and Git functionality for reviewing and managing agent-generated changes. Its automation features allow developers to schedule recurring coding tasks, while integrations with GitHub, Jira, Linear, and other services connect agents to existing development workflows. The software supports local and remote execution environments and is available for macOS, Windows, and Linux.

About
OpenSpec is an open-source spec-driven development framework designed to bring structure and clarity to AI-assisted coding workflows. It introduces a lightweight specification layer that helps teams define requirements before writing code. The platform organizes each change into structured artifacts such as proposals, specifications, designs, and task lists. It integrates with over 20 AI coding tools, allowing developers to use their preferred assistants while maintaining consistency. OpenSpec emphasizes an iterative and flexible approach rather than rigid development phases. Its command-based workflow enables users to propose, implement, and archive features efficiently. Overall, OpenSpec helps developers align with AI systems, reduce ambiguity, and produce more predictable and reliable outcomes.
