Description

OpenSpec is an open-source framework designed to enhance AI-assisted development through a structured, spec-driven approach. It provides a system for defining requirements before coding, ensuring alignment between developers and AI tools. The platform organizes work into clear artifacts, including proposals, specifications, design documents, and task checklists. It integrates with more than 20 AI coding assistants, making it compatible with a wide range of tools and workflows. OpenSpec promotes an iterative and flexible process, allowing teams to refine specifications as projects evolve. Its command-based interface enables users to propose features, implement changes, and archive completed work efficiently. By introducing structure, it reduces the unpredictability often associated with AI-generated code. The framework supports both individual developers and large teams, scaling across different project sizes. It also emphasizes context management to improve the accuracy and relevance of AI outputs. Ultimately, OpenSpec helps teams build software more reliably by combining human intent with AI execution in a structured workflow.

Description

OpenCode brings AI-driven development directly into the terminal with a sleek, native TUI that adapts to your preferred theme and style. Its LSP-enabled architecture automatically detects and configures the best tools for each language, ensuring seamless coding assistance across stacks. Unlike typical agents, OpenCode is designed for true multi-session workflows, allowing multiple agents to run in parallel on the same project without conflict. Developers can instantly generate shareable links from their sessions, making debugging and collaboration smoother than ever. With support for Claude Pro, Claude Max, and over 75 different LLM providers through Models.dev—including local models— OpenCode offers unmatched flexibility. Installation is simple across npm, Bun, Homebrew, and Paru, giving developers fast access no matter their setup. Beyond the terminal, OpenCode integrates with VS Code and GitHub, extending AI power across familiar environments. For coders who want speed, flexibility, and direct control in their workflows, OpenCode is the definitive AI agent for the command line.
