What SketchScreens is
SketchScreens is a free, MIT-licensed tool that turns application source code into hand-drawn wireframes and maps of connected screens. Run `npx sketchscreens` in a repository; the command requires no installation, setup, or configuration. It reads headings, fields, buttons, and lists from components, then draws recognizable screens and labels flow arrows with the trigger for each transition. Every run prints a coverage report showing which surfaces were included. A local browser viewer lets you search, focus, and export the map. Selecting a screen reveals its route, source file, connections, and elements. Supported stacks listed by the project include Next.js, React, Flutter, Express, Vue, SwiftUI, Remix, SvelteKit, React Native, and Angular. SketchScreens runs locally, with the viewer bound to 127.0.0.1; the site says code does not leave the machine by default and there is no phone-home behavior. It is self-hostable and requires no sign-up. Intended uses include developer onboarding, product and design flow reviews, and agency audits of client applications. Houston IT Developers LLC is named in the copyright.
Good

- Generates wireframes and flow maps
- Searchable, exportable local viewer
- Supports many listed frameworks
- Code stays local by default
Watch out
- Coverage depends on detected surfaces
- Viewer is tied to local operation
- Command-line workflow requires a repository
Who it suits
SketchScreens suits developers onboarding to unfamiliar codebases, product managers and designers reviewing flows, and agencies auditing client apps. It fits teams wanting local, self-hosted analysis.
Verdict
SketchScreens gives teams a local way to visualize screens and navigation directly from source code. Its broad stack list and no-sign-up workflow are useful, while repository-based generation defines how it is used.
