PuMi review
A focused web canvas for turning product structure into developer-ready context.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
PuMi is a browser-based wireframing workspace for planning application structure before development. It is aimed at solo product planners, designers, and developers who need to arrange pages, outline navigation, sketch major interface regions, and pass structured context to coding assistants or development tools. Its workflow combines a site map, page canvases, navigation links, and a low-fidelity wireframe editor rather than focusing on polished visual design or presentation-ready prototypes.
The free plan covers the central planning workflow and allows one saved project. It includes the core site map and page canvas, wireframes, and exports in Markdown, .cursorrules, CLAUDE.md, and JSON. Premium adds more projects, AI blueprint templates, canvas appearance options, and team-related features where available. Undo and redo support page design edits. This makes the product particularly useful when the handoff target is a coding workflow: the exports can carry project structure and design context beyond the browser canvas.
PuMi’s strongest distinction is its narrow focus on structure before code. Site maps help arrange pages and navigation edges, while page canvases and layout elements provide a lightweight way to define screen composition. Premium’s AI blueprint templates extend that planning approach without changing the product’s core orientation. The tradeoff is scope: PuMi is web-only, the free tier is limited to one project, and it is not suited to teams seeking confirmed real-time collaboration or interactive prototype behavior. Choose it for organized, low-fidelity planning and developer-oriented exports; choose another tool if visual fidelity, live co-editing, or clickable prototype experiences are central requirements.
