Feature-by-feature
Mainline is a Git-native intent recording system for coding agents. It stores developer decisions as Git refs and notes, so agents can retrieve context before editing code. Features include live conflict detection (logic conflicts before Git conflicts), high-risk code traps, and a CLI (preflight, start, append, seal, hub, log, show, gaps). It integrates with Codex, Claude Code, Cursor, Copilot, and Windsurf via agent hooks and skills. Shipixen is a Next.js boilerplate generator with 63+ themes, 300+ components, and AI content generation. It offers one-click deploy to Vercel/Netlify, an SEO-optimized MDX blog, dark mode, responsive design, and full page templates (pricing, terms, privacy). It integrates with Vercel, Netlify, GitHub, MDX, TailwindCSS, Shadcn UI, Lucide Icons, Cursor, and Claude Code. Mainline focuses on repo memory for agent collaboration; Shipixen on fast landing page creation. They have no overlapping features — one is a developer tool for AI teams, the other a site builder.
