Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.


Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Swarm proxy server that can play role of a gateway





Tests Dependency Status FOSSA Status standard-readme compliant js-standard-style

Proxy to you bee node which aims to work as a public or personal gateway or to be used in CI for uploading to Swarm.

Warning: This project is in beta state. There might (and most probably will) be changes in the future to its API and working. Also, no guarantees can be made about its stability, efficiency, and security at this stage.

This project is intended to be used with Bee version 1.7.0-bbf13011. Using it with older or newer Bee versions is not recommended and may not work. Stay up to date by joining the official Discord and by keeping an eye on the releases tab.

Table of Contents


git clone
cd gateway-proxy


The proxy can manage postage stamps for you in 4 modes of operation:

  1. It can just proxy requests without manipulating the request
  2. It can add/replace the request postage stamp with one provided through environment variable POSTAGE_STAMP
  3. It can add/replace the request postage stamp with an auto-bought stamp or existing stamp that fulfils the amount, depth and is not too full or about to expire. To enable this, provide at minimum POSTAGE_DEPTH, POSTAGE_AMOUNT and BEE_DEBUG_API_URL.
  4. It can extend the TTL of a stamp that is about to expire. To enable this, set POSTAGE_EXTENDSTTL=true, provide POSTAGE_AMOUNT, POSTAGE_DEPTH with the desired amount to use and POSTAGE_TTL_MIN above with a number above or equal to 60.

In modes 1, 2 and 3, the proxy can be configured to require authentication secret to forward the requests. Use the AUTH_SECRET environment variable to enable it. support

Gateway proxy has support for which allows translating Swarm CIDs and ENS names placed under subdomains into /bzz call. This allows to have better security model for your web applications.

In order to use, set the HOSTNAME environment variable, and either or both of CID_SUBDOMAINS and ENS_SUBDOMAINS according to your requirements. You may also need to set up DNS with wildcard subdomain support.

Reupload pinned content

It can reupload existing pinned content that appear as not retrievable. To enable this, provide REAUPLOAD_PERIOD with the miliseconds that represent the time to periodicaly check pinned content status.


1. No postage stamp

npm run start

2. Hardcoded postage stamp

export POSTAGE_STAMP=f1e4ff753ea1cb923269ed0cda909d13a10d624719edf261e196584e9e764e50

npm run start

3. Autobuy postage stamps

export POSTAGE_AMOUNT=1000000

npm run start

4. Extends stamps TTL

export POSTAGE_AMOUNT=1000000

npm run start

Reupload pinned content

export REUPLOAD_PERIOD=30000

npm run start

Enable authentication

export AUTH_SECRET="this_is_some_secret_string"

npm run start

There are some ways you can make this module better:

  • Consult our open issues and take on one of them
  • Help our tests reach 100% coverage!
  • Join us in our Discord chat in the #develop-on-swarm channel if you have questions or want to give feedback

Local development with

Local development with the subdomain support is a bit more tricky as it requires to have a way how to direct local subdomains to given URL.

Easy way is to have one testing CID that you will put directly to /etc/hosts and use only that for testing.


If you want fully functional setup than you have to locally install some DNS client that will provide you this functionality. See for example here for dnsmasq solution.
