InstantPWA vs PWA Fire (open source)

Starter template, or drop-in hosted layer?

By The InstantPWA team — Product & engineering·Last updated July 8, 2026

PWA Fire is a starter template — you fork the repo and build from there. InstantPWA is stack-agnostic: paste one script into any existing site (WordPress, Shopify, Next.js, Rails) and the install prompt appears.

When to pick which

Use PWA Fire if you are starting a new project from scratch and want an opinionated PWA template. Use InstantPWA when you already have a site and want to add the install moment without a rebuild.
