Hey everyone! I'm building PRISM, an interactive playground for system design.
I wanted to build something beyond videos and architecture diagrams a place where engineers can design systems, simulate traffic and failures, discover bottlenecks, and understand why their designs break.
Hi folks! I'm Safa, a solo developer. Over the past year I kept wondering what Claude Code, Cursor and other AI tools were really doing on my machine: which files and settings they could reach, which servers they talked to, and whether any API keys were sitting in their configs.
I first built it as a free open-source tool and shared it here on Product Hunt. The feedback was kind and useful, and it showed me what people wanted next: something faster, always visible in the menu bar, and easier to set up.
One empty square, one very long cat, and a route that almost works.
I'm the developer of Stretch Cat, a little iPhone puzzle game. Swipe to stretch the cat until it hits an obstacle or its own body. Swipe back to retract the last stretch. Fill every tile to finish the board.
The part I'd love feedback on is that reverse swipe. It keeps movement and undo in the same gesture, but I want to know whether new players discover it naturally. If you've designed or played gesture-based puzzles, how would you teach that interaction without interrupting the puzzle?
The first 20 puzzles are free. After you finish the available puzzles, an optional rewarded ad unlocks another 10. One purchase unlocks all 400 puzzles and two extra cats. No subscription; unlocked puzzles work offline.
Hi PH! I'm Dave, maker of Daybreak. We launch here next Wednesday, Nov 4.
Job searching has turned into a second job: stale listings, the same work history typed into form after form, a r sum tailored at midnight. Daybreak takes that busywork off your plate:
Finds roles worth your time on employers' own job boards (400,000+ open roles, checked daily), newest first, with the reasons each one fits Tailors your r sum and cover letter from your real experience. Nothing invented. Fills in the whole application in one click, and remembers your answers so the next form fills itself Tracks every role from Saved to Offer
Hi makers We launched Gydmation AI here last week, and one lesson surprised us: AI-written n8n workflows fail for the same few reasons almost every time. Nodes that don't exist, settings from the wrong node version, guessed IDs, broken connections, expressions missing "=".
Rentgen tests your API from a single cURL: map your fields, click run, and get validation, boundary, security, authentication, and performance checks. Core testing runs locally and is free.
Disclosure: I work on marketing at XMBoost. Before paying for any lead tool it helps to know if your niche has demand in Telegram at all. Our bot (t.me/xmboost_bot) shows sample requests from your niche for the previous day, free. If demand is low, it says so. Reply with your niche, for example web studio, interior design or customs brokerage, and I will post what we find. XMBoost itself watches public Telegram chats and sends your team the messages where someone is looking for a service, with an AI score from 1 to 100. It never messages anyone for you.

I've been working on something I'm really excited to share with you!
Meet Scailly a platform built to help small YouTube creators get their videos discovered and grow their channels without spending money on expensive advertising.
I got tired of word processors fighting us, so I built Texta launching 30 October.
Things every editor is bad at, and what we did about them: Moving images is painful drag, resize, wrap, snap, nudge with arrow keys. 60fps. Print produces blanks every on-screen page is exactly one printed page. (No Overflows!) Cluttered ribbons one searchable command palette. Slow and bloated lean engine, instant response.
Free and Heavily Optimized Optimized for all devices, free for all, forever (Promised).
