<body>
<h2>What is this site?</h2>
<p>
Blaze is an ultrafast search engine. The purpose of Blaze is to minimize
the transferred data between clients and servers, allowing users to
navigate the web in a minimalist manner.
</p>
<h2>Why?</h2>
<p>
One day, I exceeded my monthly data limit for high-speed browsing. As a
consequence, my internet speed was significantly reduced. Consequently,
web pages took an extremely long time to load, and I encountered timeout
errors 90% of the time. It was at that moment that I contemplated a
solution to this issue and conceived the idea of Blaze. Now, I can surf
the web super fast and access the information I need even without a
high-speed connection.
</p>
<h2>How?</h2>
<p>
It's actually very straightforward. When you click on "BLAZE IT!", the URL
changes to https://blaze.cyclic.app?q= followed by the query you searched
for. This address is where the backend is hosted. When the site is
accessed with the "q" parameter, a simple Node.js application retrieves
the search results and generates an extremely lightweight version of SERP
(Search Engine Results Page). From there, if you click on a link, it will
be parsed and a page will be generated with only the content (I used the
same library that Firefox uses to generate the reader mode). This makes it
possible to navigate using only a few kilobytes of data instead of
megabytes. <br /><br />If you are offline yopu can see the pages you
already visited, and also if you are online, those pages will be cached
and blazing fast. <br /><br />If you want a more detailed explanantion on
how Blaze works under the hood, I suggest you to
<a href="https://github.com/daaanny90/blaze-this-page"
>check the gitub repo</a
>
(if you have a fast connection).
</p>
<h2>Does it work?</h2>
<p>
Yes, even with a poor internet connection, you can search for things and
load pages extremely quickly. When you click on "BLAZE IT!" and select a
search result, you receive a webpage that is only a few kilobytes in size
instead of several megabytes. This makes it possible to load the page even
under challenging connection conditions, effectively preventing timeout
errors from occurring. Moreover with the offline and caching support, the
pages you already visited throug Blaze will be... blazing fast.
</p>
<h2>Other implications</h2>
<p>
This project was born to address an issue with slow internet connections
while allowing continuous web surfing. During development, I discovered
several other positive implications. Browsing a lightweight and
minimalistic web puts less stress on the phone's battery and processor. It
is mostly free from ads, and it likely has other, albeit possibly minor,
impacts on the environment (e.g., reduced battery drain, decreased need
for frequent phone charging, and lower CO2 emissions). Moreover, Blaze can
serve as an "emergency search engine" for browsing the web in challenging
connection situations, and it can even be a lifesaver at times.
</p>
<h2>Open Source</h2>
<p>
<a href="https://github.com/daaanny90/blaze-this-page"
>The code is open source</a
>, and you can host your hown version of Blaze, or contribute to it.
</p>
<h2>Who I am?</h2>
<p>
I am Danny, you can learn more about me
<a href="https://dannyspina.com">on my website</a>

<h1>Why are some pages unable to be blazed?</h1>
<p>
The purpose of Blaze is to allow users to navigate the web and access the
content they need even in challenging connection situations or when
seeking a minimalistic resource and data usage. However, generating a
"pure HTML only content page" from every page is not always possible.
</p>
<p>
Blaze utilizes the same library that Firefox uses to generate the "read
mode" of a page, providing a distraction-free and minimalist version for
better content absorption. However, this library is primarily designed for
reading purposes. Therefore, when navigating to websites like Amazon that
do not contain readable content, Blaze cannot generate a minimalistic
version of the website.
</p>
<h2>But the page was an article/blog post!</h2>
<p>
In such cases, it is possible that Blaze has detected a false positive. It
would be greatly appreciated
<a href="mailto:support.blaze@dannyspina.com"
>if you could provide the URL of the page</a
>
where you encountered this message while expecting it to work. This
information will help me reduce false positives for other users as well.
