Project Euler FrillFrill.co is particularly recommended for product managers, SaaS companies, and startups looking to prioritize and manage user feedback effectively. It is also beneficial for teams looking to enhance customer interaction and transparency by clearly communicating product development progress and updates.
We are using Frill to collect user feedback and feature requests, as well as post announcements about new feature updates to our users.
I love how easy it was to connect Frill with our own system, including SSO support for seamless users authentication. We also integrated the Frill widget right into our product user's dashboard so it's easy to distribute announcements and collect new feature ideas this way.
One of the most satisfying product experiences I've had with a tool for our business. Their customer support is top-notch as well.
Frill is thoughtfully designed and simple to use while offering a complex and powerful level of customizability. It integrates seamlessly into our web app and has become a crucial part of the feedback loop with our customers

I have a Project Euler (https://projecteuler.net/) account. Though I do not register at all on the leader board I will sometimes work obsessively on a problem just to make one of the level icons light up for me. There is not really competition just a tiny reward. - Source: Hacker News / 7 months ago
I do hobby programing. It is sometimes to create something (supposedly) useful. Lately though it is more discovery and a little math like. I enjoy Project Euler (https://projecteuler.net/. Recently I have been playing with superpermutations (https://projecteuler.net/) and pencil and paper is useful but filling lots of paper with lots of numbers is not that fun. - Source: Hacker News / over 1 year ago
As pointed out in a sibling comment, it appears that quote only shows up if you're logged in, but assuming you have an account and are logged in, it's on the homepage (https://projecteuler.net/), second paragraph under the following heading: > I learned so much solving problem XXX, so is it okay to publish my solution elsewhere? > It appears that you have answered your own question.
