I made a website about prime numbers

0 Upvotes

I made https://primenumbercheck.org/ - It is a website that allows you to check whether a large number up to 20k digits is a prime number, plus a lot of information about prime numbers.

Full disclosure: I'm just an engineer with some odd interest about prime numbers, I'm not a mathematician so I cannot guarantee everything there is correct. But I did my best.

It's 100% free. No ads, no accounts, no tracking. Just a little side quest project. I hope someone finds it interesting.

A website perfectly recreating how YouTube looked and functioned back in 07.

What to post:

Single purpose websites.
Top-level domains.
Web Tools.
Minimal or beautifully designed websites.
Awesome websites that offer a unique service.

Rules:

Aggregators/Collections - Websites that are aggregates for other content are not allowed.
Sites That Are Not Unique - Not unique submissions could be websites everyone on the internet already knows about, websites that do very similar things to previous submissions, websites that are very basic (e.g., a website with a timer or a website to take notes), or submissions that have been recently posted on this subreddit.
Webgames - Webgames are not allowed. This includes quizzes, puzzles, etc.
Articles, Videos or Images - Articles, videos and static or animated images are not allowed, this includes collections (such as galleries). Blog posts, LinkedIn posts or similar are also not allowed.
Online Stores, Paid Services or Demos - We do not allow any sites that are online stores, sites that serve only to sell a specific product, or paid services. Free demos or freemium tiered services where the full version or key functionality requires payment are also not allowed.
Websites That Require Personal Information - Websites that require an email address, name, or any other personal information to fully experience the website are not allowed. This includes Facebook, Google, or any other account. Also included are sites that simply serve as waitlists or newsletter sign ups, and so on. Additionally, this rule also extends to websites that require a webcam in order to function.
Extensions or Downloads - Extensions, software (mobile or desktop), or other content which requires being downloaded before being used are not allowed.
Hug of Death (╯°□°)╯︵ ┻━┻ - Website is slow or unresponsive. Reddit has hugged it to death and the site needs a timeout.
Politics - Sites that serve a political agenda or otherwise induce drama. (Neutral political submissions may be considered).
AI-Generated Content - To prioritize human ingenuity and effort, submissions are not allowed if their primary content is produced by AI, or if AI is used to drive functionality (especially for tasks that do not inherently require AI).
Accounts Designed for Self-Promotion - This sub follows the 90/10 rule for self-promotion. If almost all your activity on Reddit is advertising something you made, you will not be allowed to post here. 90% of your participation on Reddit should have nothing to do with a site you own or operate.
Business Tools - Posts featuring tools designed for launching products, job boards, SEO optimization, or any other tool aimed at businesses are not allowed.
Civility - We enforce a standard of common decency and civility here. Personal attacks, bigotry, fighting words, and otherwise shitty behavior will be removed and may result in a ban.

Moderator Discretion

Beauty is in the eye of the beholder, but we have beheld a lot! This subreddit is highly curated and the moderators frequently must use their discretion and judgement as a team when enforcing our rules.

Something different? Try /r/InternetIsUgly. If you exhibit a similar addictive lust for information as you do for internet, we highly recommend you go give /r/dataisbeautiful a sub too.

If this subreddit for whatever reason fails to provide the interactivity you need, we also highly recommend a look at /r/interactivewebsites for a less diluted dosage of interactivity.
