CDN speed up web content delivery by serving cache content from the server nearest to the user’s location, which improves website performance. It also helps to reduce hosting bandwidth cost, while provides content availability and redundancy.

With the distributed nature, CDN can handle more traffic and withstand hardware failure than origin servers. CDN may also help to protect website against bad bots and DDoS attacks.

Staticaly is a free, multi-network CDN to serve your static files. Unlimited quota. Unlimited bandwidth. Awesome!

It is an open source project maintained by Marsble. Staticaly founder, Frans Allen is a tech entrepreneur in Indonesia. He leads a team of 7 developers at Staticaly.

Another project core team member is Taufik Nurrohman, who is the founder of Mecha CMS, a flat-file content management system with no dependencies.

Their goal is to make static files easy to manage and fast to deliver.

Yes, Staticaly is totally 100% forever free and unlimited.

They have no plan to offer paid version of Staticaly yet. Even then, it will be a separated service at a different domain, Frans told RunCloud.

Staticaly is a Multi-network CDN

Staticaly is a multi-network CDN with data centers around the globe.

The global CDN network is powered by 4 CDN providers: Cloudflare, Fastly, CDN77, and BunnyCDN.

Currently, Staticaly has 10 data centers in Jakarta (2), Singapore (2), Frankfurt (1), Amsterdam (2), Ashburn (1), Los Angeles (1), and Hong Kong (1).

Staticaly has a healthy infrastructure. If a CDN data center is not available (down), Staticaly CDN will re-route to another data center.

Staticaly has served over 6 TB data and over 8 millions unique visitors.

HTTP/2 and Brotli for all traffic

Staticaly comes with modern technologies and uses HTTP/2 for all the network traffic. HTTP/2 improves performance by multiplexing, using only 1 TCP connection to deliver assets between a browser and a website.

Staticaly also uses Brotli, Google developed lossless file compression format, for smaller compressed file size than Gzip and faster file delivery speed.

CDN for image

Example: https://cdn.staticaly.com/img/i.imgur.com/3QrPToe.jpg

Resize image

You can make Staticaly to resize your origin image on-the-fly to your target image resolution (pixels) and serve it via CDN using a query parameter ?w= and ?h=. Resize by percentage (%) is coming soon.

Example: https://cdn.staticaly.com/img/i.imgur.com/3QrPToe.jpg?w=400&h=266

Custom image compression level

Not satisfy with the Imgpx default image compression? You can control the image compression by providing ?quality=:number argument on the URL. The image file size is according to the image compression level. Lower quality has a higher compression and smaller file size.

Example: https://cdn.staticaly.com/img/i.imgur.com/3QrPToe.jpg?quality=10 (Image quality 10)

Auto WebP image generation

Imgpx will automatically generate a copy of WebP image format for every image served. WebP is a new image format developed by Google that produces a smaller file size of comparable image quality to the older JPEG format.

  1. Would love to test it with my site, do you have any dates for the WP Plugin as it’s already middle of the year 2019.

    1. Hi Gerva, we have not receive update about Staticaly WordPress plugin yet. Please stay tuned.

  2. Please give example code for using statically cdn for wordpress plugin, css and javascript. I am only able to use the cdn for images.

    1. Hey James, you might need to install an actual WordPress CDN plugin which may automatically upload and link it for you.

  3. I’ve tried using the imgpx service from Staticaly for all images on my blog. As results, the image appear faster than before. Recommended for bloggers.

  4. Hi Liew,
    Is this now rebranded as https://statically.io/ or is that a different thing?

    I’m keen to try it out with WP Rocket but am uncertain if I should use cdn.staticaly.com/img/ or cdn.statically.io/img/.

    I only ask as whenever I search for staticaly.com, I get redirected to statically.io and am wondering if using cdn.staticaly.com/img/ will still work, and if it does will it end up creating a bunch of redirects to cdn.statically.io/img/ for all my images?

    As this is the only place I’ve found the details for WP Rocket I figured you’d be the guy to ask 🙂

    Thanks for your help!

    Kind regards,
