Builder Battles is a daily showdown for indie apps. Makers enter their app, two apps go head to head, and the community votes on the winner, who takes the belt and is pinned as the reigning champion. Every past winner is listed in a hall of champions, giving makers a fun way to get their product in front of other builders and earn a little recognition.

Parents often want their kids to meet other local families but finding the right family and coordinating a first meetup can be awkward and time-consuming. Our AI agent connects nearby families and handles the coordination over SMS — introducing them, finding a mutually convenient day and time, suggesting a meeting place, and confirming the meetup once both sides agree. We're initially targeting homeschool families and parent communities. We want to learn whether parents trust an AI agent to facilitate these introductions, which parts of the process they want automated, and whether they would pay for the service.

An app which allows you to select a route based on a set of filters. Built by people who enjoy driving, for those who drive. Built for whom the drive is the point, not the arrival. Weekend riders looking for a road they haven't done, people new to a city wanting the one their local club already knows, riders who want a record of what they've driven. Built as a PWA, can be installed on your phone directly from your browser.

Dental Scope is a free interactive 3D model of dental anatomy for students and educators. It covers all 32 permanent teeth with FDI, Universal and Palmer numbering, from enamel and dentin to root canals, plus the jaws, joints, nerves, arteries and muscles of mastication. You can toggle layers, search structures, and switch between front, side, top and occlusal views, with fixed or free orbit around the model.

Scissor is a free graphics editor for vector and pixel work that runs entirely in the browser, with no install, no account and no upload of your files. It has the tools designers expect: selection, pen, type, shapes, paintbrush, gradients, transforms, layers, multiple boards and grids, with keyboard shortcuts and a command palette. The interface is available in more than a dozen languages.

Ledge is a Markdown notes app where the code blocks run. Write a shell command, code, a SQL query or an AI prompt in a note, run it in place, and the output streams in right beneath it, so your notes double as working runbooks. Notes live in workspaces with profiles for keys and database URLs, which makes it handy for API scratchpads, weekly checks and operations notes. It is free and open source, for Mac, Linux, Windows, iPhone and Android.

Tiny AI Arena pits AI models against each other in game matches and keeps an Elo leaderboard of the results, with wins, kills, damage and average placing for each model. Every finished match has a replay you can watch, so you can see how different models actually play rather than just reading benchmark scores.
