Open a file. Hit ⌘R. Done. No project setup, no config files. A lightweight IDE for developers who want to code, not configure.
Q: I answered correctly, but it says "Invalid form submitted." What do I do? A: Your browser’s referrer policy is too strict. Switch to Chrome or Edge temporarily. Firefox with "Strict" privacy settings often breaks the phpBB form token.
Q: Is the forum down? I can't reach cs.rin.ru at all.
A: The domain is often blocked by ISPs at the DNS level (especially in the UK, Germany, and Australia). Change your DNS to Cloudflare (1.1.1.1) or Google (8.8.8.8). If still blocked, the forum uses alternative ports; try http://cs.rin.ru:8080 (rarely works now).
Q: I got banned before even registering (IP ban). Why? A: Your IP range was previously used by a spammer. Wait 24 hours with your modem off to get a new IP, or use a mobile hotspot.
Q: Can I pay to skip the register question? A: No. There is no premium registration. Anyone offering to "sell" a CS.RIN.RU account is a scammer. Accounts are free.
Q: What if the register question asks about "Gaben" or "Valve"? A: The admin once used a joke question: "Who is the father of Steam?" The answer is Gabe Newell (or "GabeN"). If you see this, you are on an older cached page. Hard-refresh (Ctrl+F5) the register page.

For the uninitiated, cs.rin.ru (often shortened to "CS RIN" or "RIN") can look like a relic from the early 2000s internet. With its stark phpBB layout, aggressive anti-bot measures, and cryptic internal slang, it is intimidating. However, within the niche world of game modification, Steam emulation, and software preservation, CS RIN is nothing short of a digital Library of Alexandria.
Named after the protagonist of the Patlabor anime (Noa Izumi’s pet baboon), the forum has existed for nearly two decades. It is the global headquarters for SmartSteamEmu (SSE), Goldberg Emulator, and the primary archive for Steam Content Sharing (Steamstubs). Unlike piracy sites that distribute repacks or cracked executables, CS RIN focuses on the tools and knowledge to make legitimate game backups run without a launcher.
But to access this vault, you must pass a single, infamous hurdle: Registration.
Good luck — follow these steps and you’ll create an account that’s welcomed and respected by the community. Q: I answered correctly, but it says "Invalid form submitted
Follow these steps exactly to avoid a 24-hour lockout.
Step 1: Clear your cache. Open your browser (Firefox or Chrome, no Brave Shields). Clear cookies for the last hour.
Step 2: Disable all extensions. Turn off uBlock Origin, Privacy Badger, and especially NoScript. The forum’s captcha system relies on JavaScript.
Step 3: Navigate to the Register Page. Go directly. Do not click through from a search engine referrer (this sometimes triggers a soft-block).
Step 4: Enter your username. Do not use "Cracker123" or "SteamHack." Use a neutral, non-threatening name. If you log in and immediately try to
Step 5: The Register Question Box.
Step 6: The Visual Captcha. A standard reCAPTCHA appears. Pass it normally.
Step 7: Submit. Wait 5 seconds. Do not double-click.
Success: You will see "Your account has been created. An email has been sent to your address."
Failure: You see a red box. Do NOT try again immediately. Wait the full 24-hour cooldown. Repeated attempts reset the timer.
Native performance, no splash screen, no indexing. Here's what's in the box.
Prototype SwiftUI and UIKit screens — test APIs in the Simulator without ever opening a project file.
Edit and run SwiftPM packages directly. Target macOS or Linux — the Linux subsystem installs itself.
Build SwiftUI applications with animations and interactive UI. Export a .app when you're ready.
Custom interpreter settings, built-in documentation, instant execution. Scripts and automation without the setup tax.
Keep a scratch window floating above everything while you work in the app you're really debugging.
One shortcut turns any snippet into a shareable image — syntax highlighting, window chrome, the whole thing.
Swift developers who got tired of waiting for Xcode to finish indexing.
I really dig the Notes Library and the ability to pin a window to the front. Cot does too little for me, Xcode is overkill for small things so I really love this.
It's an excellent small code editor to explore all your Swift ideas without launching a heavy IDE like Xcode. The option to create an image for sharing code is just perfect!
I was really impressed with the performance, only to learn Notepad.exe is a native app. Where Xcode playground has to work despite Xcode's years of legacy, Notepad.exe has a very promising future.
It's fast, lightweight and refreshingly low-friction — allowing one to jump straight into experimenting with code snippets. It's exactly the Swift playground we've all been wanting.

Both! It's a lightweight IDE with code completion, live error detection, and instant execution — without the bloat. Think Xcode Playgrounds done right.
I like to live dangerously.
We've got Swift, Python, and JavaScript covered. More languages? Maybe. Stay tuned!
Works with just Swift Toolchain, but having Xcode's SDK lets you run applications. Like having both the recipe and the oven!
Yes, it runs iOS code now. You can build SwiftUI apps, work with UIKit, or experiment with any iOS API using the built-in iOS Simulator integration.
No, but there's an app named kindaVim that is 100% compatible, and I recommend it!
It might transform into one after midnight. Who knows? Check out swiftstudio.app.
For very mysterious reasons, like protecting the last piece of grandma's secret pie recipe. Plus, parts are open source on GitHub, so I'm not a total villain!
