Community votes come from makers and cannot be bought. DR is Domain Rating by Ahrefs.
Makers paid to hang these on the wall. Biggest total goes first. Community votes are never sold and live on their own board.
Open source is the workshop with the door left open. Everything in this category is built in public, with source anyone can read, fork and fix. Expect solo builders and small crews shipping apps you can run today, libraries you can bolt onto your own build, tools you host on your own kit and models you can inspect and retrain.
Listings appear newest first, and you can sort by community votes instead. Votes can never be bought, so the order reflects real interest. When you compare projects, read the licence, check the docs for a clear first step, and see how the maker talks about what is unfinished. A good bench has honest labels on the drawers. Use the subcategories below to narrow the pegboard, or filter within them.
