archive.is, also known as archive.today, is a website that lets you save a copy of any webpage. It works like a time capsule, taking a "snapshot" of the page as it is at that moment. This snapshot stays online even if the original page is deleted or changed. It saves both the text and images, making sure the copy is accurate. The archived page doesn’t have active elements like pop-ups or scripts, so it’s safer to view. People use archive.is for different reasons—saving articles that might get taken down, capturing price lists or job postings before they change, or keeping a record of social media posts. It’s also used to get around paywalls, since the archived copy often shows the full content without restrictions. You can use the site by entering the URL of the page you want to save. Once archived, you get a short, stable link to the snapshot. There’s also a search feature to find past snapshots of certain websites. They even offer a Chrome extension for quicker access.

Paywall Reader is a tool that helps you read articles blocked by paywalls. It doesn’t hack into sites or break paywalls directly. Instead, it sends you to archived or cached versions of the page. These versions are saved copies from places like Archive.Today, the Internet Archive, or even Google Translate. It works best with soft paywalls—those pop-ups that block the screen but still have the full text underneath. To use it, you just paste the article’s URL, pick an option from the three services, and it tries to find a version without the paywall. If one doesn’t work, you can try another. Not every paywall can be bypassed, especially if a site blocks archiving, but most major news sources work fine. It’s considered legal because it doesn’t tamper with the website itself—it just finds copies that are already available online. People use it to access news without needing tons of subscriptions or for things like schoolwork and research. The site isn’t connected to any of the archive services or news outlets, and it leaves the responsibility of use to you.

Convert any webpage into a print-friendly format, enjoy a built-in Reader Mode for distraction-free browsing, and save webpages as PDFs for easy access.

The recipient clicks once to view or download, no account required. It’s the fastest path from “I have details” to “you can see them,” especially when a site limits formatting or blocks attachments.

DisplayTest.org is a free, browser-based tool designed to help you evaluate your screen’s performance and identify potential display issues using full-screen color and pattern tests — all directly within your web browser. No downloads, installations, or special software are required. With a single click, you can switch between solid color screens (white, black, red, green, blue, and more) to check for dead pixels, stuck pixels, uneven brightness, backlight bleeding, or color distortion. Pattern-based tests also help detect screen uniformity problems, banding, contrast inconsistencies, and resolution clarity issues.

Uneed is a platform where people can both discover new products and promote their own. It works a bit like Product Hunt, giving creators a way to get their products noticed. Every day at midnight PST, between 10 and 20 new products launch on the homepage. On launch day, products get prime visibility, but users can keep voting for them anytime afterward. Products are ranked daily, weekly, monthly, and yearly. The top three products in each ranking get badges—gold, silver, or bronze—displayed on their product pages. Popular products also get featured in Uneed’s weekly newsletter, which reaches over 9,100 subscribers. If you want to launch a product, you make an account and fill out the details. There are two ways to get your product live: wait in a free queue (and get assigned a random launch date) or pay $30 to skip the line and pick your date. Success comes from a strong launch day, keeping your page up-to-date, and encouraging people to vote. Adding special deals can also earn you a badge and keep interest alive. The community side of Uneed is built around upvoting products. The more you vote, the more power you gain. For example, a 5-day voting streak doubles your vote’s power, and a 100-day streak triples it while unlocking an avatar border. At 150 days, you get a free line skip; at 500 days, you get discounts on advertising; and at 1,000 days, your votes count as five. The platform covers categories like development, design, marketing, business, and personal life products. It’s just one person running Uneed, and you’re encouraged to vote for your own product. If you have questions, they’re easy to reach via email. In short, Uneed is a straightforward way to launch a product, gather feedback, and build an audience—without needing a massive following upfront.

These quests encourage users to explore the ecosystem more deeply, stay curious, and interact with projects in more meaningful ways.
