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.

About

Spec24 is an AI-powered client hub for small agencies and freelancers. It gives your clients a simple portal to submit and track requests, while your team manages everything on an AI-powered Kanban board. When a client submits feedback, Spec24 automatically translates it across languages and turns vague requests into clear, actionable tasks, so nothing gets lost between what the client asked for and what your team builds. Instead of chasing context across email, chat, and spreadsheets, everything lives in one place: client submissions, task boards, comments, and internal notes. Clients get a clean, easy interface; your team gets structured specs, AI categorization, and full project visibility. Built for teams that have outgrown scattered tools but do not want the complexity of ClickUp or Jira. Client seats are free, with simple flat-rate pricing for teams of 1 to 10.
