Welcome to the first edition of The Product Stack — a weekly roundup of tools, resources, repos, and communities worth your time as a software product designer or developer. No fluff, no sponsored picks. Just the stuff I’d actually tell you about over coffee.
Let’s get into it.
Design Prompts
If you work with AI tools to generate UI, you know the frustration of getting generic, uninspired results. Design Prompts is a curated library of ready-to-use prompts specifically built for designing beautiful, consistent interfaces. Pick a style, grab the prompt, drop it into your AI assistant of choice, and ship something that actually looks intentional. The prompt library covers everything from minimalist light themes to bold editorial styles, and you can preview exactly what each one produces before you use it. A genuinely useful shortcut for anyone who wants quality AI-assisted UI without spending an hour crafting the perfect prompt from scratch.
This is a tool I am currently using to quickly prototype websites for some new projects I am launching. They are great starters but I would caution on using them on client project without serious code review. Remember, prompts are useful but should never be taken as final.
Oat Components
Oat is an ultra-lightweight HTML + CSS + minimal JS component library with zero dependencies and I mean zero. No framework, no build step, no npm install. You just include the tiny CSS and JS bundles and your semantic HTML is styled contextually out of the box. I love it. What makes this interesting is the philosophy: instead of adding class names to everything, Oat reads your semantic HTML and applies styles accordingly, which enforces good markup habits by design. For prototyping, internal tools, or any project where you want something functional without the overhead of a full component system, Oat is worth a look. It won’t replace your design system, but for the right use case it removes a lot of friction.
Sub-Reddit to Follow: r/AppsWithoutSub
Link: reddit.com/r/AppsWithoutSub
Subscription fatigue is real, and this subreddit exists specifically to surface apps that don’t have one. It’s a community-curated list of mobile and desktop apps that you pay for once, or better yet, get for free — no recurring charges, no paywalled features. Whether you’re building products and looking for inspiration from models that respect their users, or like me, you’re just tired of another $9.99/month charge on your statement, r/AppsWithoutSub is an underrated find. The community is active, the posts are well-tagged, and you’ll consistently stumble across things you didn’t know existed.
Git Repo to Star: Awesome Web Components
Link: github.com/web-padawan/awesome-web-components
Web Components remain one of the most underutilized parts of the modern web platform, and this repo is the best single starting point for getting up to speed with them. It’s a carefully curated “awesome list” covering everything from introductory resources and tutorials to tools, component libraries, frameworks, and real-world examples built on the Web Components standard. With 3.4k stars and active maintenance — the last commit was just two weeks ago — this one earns a permanent spot in your starred repos. If you’ve been meaning to take a deeper look at custom elements and shadow DOM but didn’t know where to start, start here.
Cool Project of the Week: The Git City
This one is just wonderfully cool. Git City is a 3D city visualization built from GitHub data. Every developer who connects their account gets a building in the city, sized and styled based on their contribution activity. You can fly through the city, explore in real time, and watch the live feed as developers around the world push code and join. There’s a leaderboard, streaks, achievements, and a lo-fi soundtrack playing in the background. It’s part game, part developer community, part creative experiment and it’s currently home to over 57,000 GitHub developers. Not every cool project has to be immediately practical. Sometimes something just earns its place by being genuinely fun to explore. This is one of those.
Must Have Tool: Tailscale
If you haven’t used Tailscale yet, this is your sign. Tailscale is a Zero Trust networking tool built on WireGuard, that makes it trivially easy to create a private mesh network across your devices, teams, and cloud infrastructure without touching firewall rules, VPN servers, or any of the configuration hell that comes with traditional networking. For developers, it means you can securely access a home server, a dev environment, a database, or a CI runner from anywhere, in about five minutes of setup. For teams, it replaces expensive and fragile VPN infrastructure with something that just works. The free tier is genuinely useful for personal use and small teams.
I currently have Tailscale deployed across most of my network. What I find most useful is how I can now automate tasks across my devices using a combination of n8n+Claude Code+Tailscale. Using the service I am able to access my own hosted AI assistant from every device I use in my day to day.
If you’re looking for an open-source alternative to evaluate alongside Tailscale, Firezone is worth keeping an eye on. Built on WireGuard as well, Firezone is a self-hostable zero-trust access platform backed by Y Combinator. We haven’t done a full head-to-head comparison yet, but it’s on our list — and the self-hosting angle makes it compelling for teams with compliance requirements or anyone who wants full control over their networking stack.
That’s the first edition of The Product Stack. Back next week with six more. If something here was useful, share it with someone who’d appreciate it.
