An FPS game built as a parent-friendly alternative to Roblox.
davitb · HN
I'm a father of two, 7 and 12. They are obsessed with Roblox, especially Rivals. Like a lot of parents, we did not love it. We tried the usual things: block it, limit it, set timers." It became a daily battle, a lose-lose situation. So I flipped the problem. Instead of fighting what they loved, I decided to lean into it, but with a twist. Why just play an FPS when you could build one together? My kids became the PMs. Claude and I became their engineer. I was shocked by how fast we moved. We picked a name, Cooked and started building. Get in. Lock in. Get cooked! In the first 3 hours, we had an actual FPS we could play together in the browser. Next day I invited my friend's two kids over. Suddenly, I had four PMs. We had 3 laptops, 1 iPad and 1 iPhone. So in 30mins we added mobile support and could play all 5 together. The kids would ask for features: "Can we have a rocket launcher that knocks people off the map?" "The knife should stab faster when you hold it." I know al

Not AI-generated. No sign in required. Free tool to use. My name is Zachary and I've built this app a few times now, in different seasons and with different frameworks.

As someone who loves to cook, it has a lot of features I know I will personally use, such as: - different sizes for printing [for different index cards] - allergen information - macros - easy way to scale up or down ingredients - can switch between metric and imperial measurements

Embeddable visual workflow builder for web apps with optional AI assistance.

Hi! I’m Taha. In many agentic products that support workflows (including one I worked on), I noticed they either don’t support node-based editors, or use React Flow and go through the difficult work of integrating it into their product to run it and work with their existing logic. So I thought about creating a tool that could help with this by closing the gap between the editor and the runtime. That’s why I created Wayflow. The basic architecture is simple: you just need to create a graph (which is a JSON object) that the runtime knows how to run. The runtime doesn’t care where that graph is coming from, it just needs the right schema. And with the help of the editor, you can create the graph, and then export it or directly save it on your backend in your database. And then when you want to execute it, you just hand it to the runtime. The runtime can either stream the execution (which is useful for the editor), or give you the final result. How you execute the graph is up to you: t
