Capabilities

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.

How it works

Analyze. Defer.
Minify.

1

Analyze

pageflare scans every script on the page and determines which are critical to initial render and which can safely load later.

2

Defer

Non-critical scripts get the defer attribute. Critical scripts that must run immediately are left untouched.

3

Minify

All JavaScript — inline and external — is minified. Whitespace, comments, and redundant code are stripped from every file.
