Stop JavaScript from
slowing your pages.
pageflare automatically defers non-critical scripts and minifies every JavaScript file. Your pages render instantly while scripts load in the background.
Leaner scripts,
faster pages.
Faster Interactivity
By deferring non-essential scripts, the browser's main thread is free for user interactions sooner. Lower Time to Interactive.
Zero Configuration
No script auditing, no manual defer attributes, no build tool plugins. pageflare handles it all automatically.
Analyze. Defer.
Minify.
Analyze
pageflare scans every script on the page and determines which are critical to initial render and which can safely load later.
Defer
Non-critical scripts get the defer attribute. Critical scripts that must run immediately are left untouched.
Minify
All JavaScript — inline and external — is minified. Whitespace, comments, and redundant code are stripped from every file.
Lighter JavaScript, faster pages.
Install the CLI, point it at your build output, and see results in under two seconds.
