Why I rebuilt offline web archiving to bypass CORS (The PWAA Format)

Short summary

The author introduces PWAA (Portable Web Application Archive), a Go-based format that packs entire web apps into a PKZIP container and serves them via an in-memory HTTP server on localhost, bypassing CORS restrictions. It solves SPA routing 404s, video streaming range requests, and security isolation. The format targets offline distribution of complex interactive web apps without cloud hosting.

• •PWAA packages web apps into a ZIP served via in-memory localhost HTTP, bypassing CORS
• •Solves SPA routing fallback, video range requests, and external-link isolation
• •Built in Go with a CLI builder supporting pack, build, and framework-detection modes
