Turning Your Website's Users into Seeders

What is Planktos?

Planktos enables websites to serve their static content over BitTorrent by turning users into seeders. This allows website owners to significantly reduce hosting costs for static content, scale in real-time without provisioning more web servers, and prevent user impact during an outage.


Planktos uses WebTorrent to convert users of your website into seeders, enabling them to serve static content to other users. This reduces server bandwidth and makes your website more resilient.

Simple & Easy Integration

Using Planktos is as simple as including the Planktos install script and using the Planktos command line interface to bundle your website's static files into a torrent.

Avoid downtime

Planktos can serve your website even if your web servers go down. Any users that visited your website prior to an outage will still be able to access it.

Auto Scaling

Since Planktos turns users of your website into seeders, any increase in demand is also an increase in supply; with more users, downloads get faster.


Planktos has sensible defaults and a simple interface for customization, allowing you to tweak it to your needs.

Supports top browsers

Planktos supports Chrome and Firefox with no plugins needed. When Planktos encounters an unsupported browser it gracefully falls back to default settings.


All files downloaded from peers are verified with SHA-1 as required by the BitTorrent specification.

Supports all file types

Whether it's HTML, CSS, Javascript, images, videos, or something else it all works with Planktos.

Improved Caching

Once files are downloaded, they are persisted to disk and used for any subsequent requests. Since Planktos stores file hashes, there is no need for the browser to ask your web server if any files have changed.
