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

Swifter governs AI across the full software development lifecycle. Unlike code-only assistants that deliver ~10% productivity gains, Swifter's spec-driven agents cover the entire SDLC — from business requirements through design, code generation, testing, and delivery — achieving 25-30% gains. Built for enterprise: full traceability from requirement to delivered code, audit trails, compliance enforcement, and consistent output across hundreds of developers. Supports both greenfield and legacy modernization. Partnered with Tech Mahindra (1,100+ enterprise clients).
