Phase 03 · Build
Build
The Build phase is where a builder ships the actual product without a team - UI and frontend, backend, data and payments, integrations, agent skills and templates, docs and project management. Skillselion organizes the complete catalog of AI-coding skills, MCP servers, marketplaces and workflows for this phase and highlights the best tool for each layer of the stack.
The top-ranked Build-phase tools for solo builders are frontend-design, vercel-react-best-practices, microsoft-foundry.
