[Other] Show HN: A web version of Pips game (NYT domino game) Hi everyone,<p>I’m an indie developer learning Next.js and a big fan of the NYT game Pips. Inspired by it, I built <a href="https:&#x2F;&#x2F;pipsgamer.com" rel="nofollow">https:&#x2F;&#x2F;pipsgamer.com</a> — a responsive web version of Pips with smooth gameplay on both desktop and mobile.<p>What makes this project different from NYT’s version is that you can play it infinitely under three difficulty levels: Easy &#x2F; Medium &#x2F; Hard.<p>This is the first time I’ve built a game. Along the way I ran into many difficulties: implementing the game logic, configuring the UI, matching layouts for small and large screens, etc. I spent many lonely nights and sometimes even doubted whether I could complete the whole project. After 24 days of persistent effort, the project is finally finished.<p>No signup required — just go and play. If you try it out I’d really appreciate your feedback: what you like, what bugs you see, what could be improved.<p>Thanks!

[Other] Show HN: Macscope – I decide to built a better Cmd-Tab replacement for macOS Hi HN,<p>Macscope is a new window manager and and app switcher for macOS built on the philosophy of enhancing, not replacing, your existing muscle memory.<p>It works by augmenting the familiar Cmd+Tab workflow. A quick tap of your shortcut instantly switches between recent apps, just like you&#x27;re used to. A slightly longer hold, however, opens the full Macscope interface where you can manage all your open windows and tabs.<p>You can also use modifier shortcuts to enter Placement Modes, which let you instantly snap a selected window to the left&#x2F;right&#x2F;top&#x2F;bottom&#x2F; half of your screen.<p>Here are some of the key features:<p>- Unified Search &amp; Switch: A single interface to instantly find and switch to any window, browser tab (Safari, Chrome, Arc, etc.), or application just by typing.<p>- Live Previews: See a real-time preview of what&#x27;s inside each window so you know exactly where you&#x27;re going. You can also disable previews for a more minimal experience.<p>- Advanced Window Management: Go beyond just switching. Select multiple windows and arrange them into layouts like vertical&#x2F;horizontal splits or grids.<p>- Scopes: Save collections of app windows as a &quot;Scope&quot; and instantly restore that entire workspace later. It&#x27;s ideal for quickly switching between different projects or tasks.<p>It’s a native macOS app built with Swift and supports both Apple Silicon and Intel machines.<p>Launch Offer for HN:<p>There&#x27;s a free trial with 250 actions.

[API/SDK] Show HN: Prism – Let browser agents access any app Hey HN, We’re Alex, Land, and Rajit. We’re building Prism (prismai.sh), a tool that helps browser agents authenticate onto websites with user credentials. Developers pass in credentials, Prism logs into a website on their behalf, and hands them back the cookies so they have an authenticated session. Here’s an example of how developers can use Prism to complete username&#x2F;password flows (<a href="https:&#x2F;&#x2F;youtu.be&#x2F;SEtVUnWnxuE" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;SEtVUnWnxuE</a>), and here’s an example of how developers can use Prism to complete login flows that require an OTP code (<a href="https:&#x2F;&#x2F;youtu.be&#x2F;fe9w9PvrwH0" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;fe9w9PvrwH0</a>).<p>We spoke to browser agent developers and saw people copying and pasting credentials and even credit card numbers directly into model system prompts. We were surprised that there wasn’t a better way to give agents access to websites on a human’s behalf. Moreover, we noticed that every company had to build infrastructure to manage OTP, TOTP, and MFA and that auth remained a significant hurdle in agent reliability. We wondered if this was a boring part of the problem of building web automations that someone could automate away.<p>We started working with Casco, an autonomous security testing company, to enable their agent to access customer sites. Before a pentest, Casco makes a request to Prism’s API specifying test user credentials, a domain, and a login method. For example, give me an authenticated session for the account rajit@prismai.sh for OpenAI via OTP code over email. Our agent logs in on their behalf (without exposing credentials to a model), and we download the cookies and send them back in the response.<p>To maintain speed and reliability, we use playwright in most cases to login (which gives us speed), and we fallback to AI on failure (which gives us reliability). We have a number of websites we support out of the box and add new scripts as the number of websites we need to support grows. We are working on a way for the agent to update the existing playwright script on failure, so our scripts always stay up to date.<p>To try our api, you can use our API playground docs.prismai.sh&#x2F;api-reference&#x2F;endpoint&#x2F;login to sign into x.com with the following API key: pk_54abb1cd0a637eb973ed690416e71a953e98f2ea839cf16529bbfa41a41bc016 .<p>We’d love to learn more about how other developers give agents access to their accounts. We look forward to everyone’s feedback and comments.
