If you are into coding and AI tools, you already know how much hype there is around Claude Code. But let me share my raw experience with you. When I first tried to install Claude Code on my PC, it was a disaster. My PC is a bit older, and Claude Code just lagged too much. It demanded a lot of RAM and felt too heavy. I was frustrated. Then I discovered Free Buff, and honestly, it changed everything for me. I’ve been using it for quite a long time now, and today, I’m going to share exactly why this tool is a game-changer, especially if you don't have a high-end PC.
Why Free Buff is a Lifesaver for Low-End PCs
Here is the best part: Free Buff does not require a super powerful PC. Everything runs on the cloud. You don't even need an API key or a paid subscription to get started. Even if your PC only has 2GB of RAM, it will run smoothly without any lag. Unlike Claude Code, which felt like a heavy burden on my system, Free Buff is lightweight, fast, and extremely easy to install. It installs with just a single command, and you are ready to go.
GUI vs CLI: Which Version to Use?
Free Buff comes in two versions: a GUI (Graphical User Interface) and a CLI (Command Line Interface). I have used both extensively, and I can tell you that both are incredibly easy to use. The GUI version is great if you prefer a visual app, while the CLI version works directly inside your terminal. It entirely depends on your preference, but both work flawlessly.
Free Daily Boxes & Supported AI Models
Yes, it is completely free and open-source. Every day, you get free credits (boxes). Usually, you get around 25 free boxes daily. The number of boxes consumed depends on the AI model you choose. For example, DeepSeek uses 10 free boxes, while GLM 5.3 Flash uses 5 free boxes.
The tool supports all the popular open-source models. In my country, I have access to DeepSeek V4, MiniMax 2.5, and GLM (Z.ai). You can also join their Discord channel. Sometimes they drop Cloud Code quotas there, but it’s on a first-come, first-served basis and the quota is limited, so you have to stay updated.
GLM 5.3 Flash Experience: With GLM 5.3, you get 25 free boxes which allow you to run the tool for about 5 hours a day. Honestly, 5 hours is more than enough for most projects. Even if you exceed this, their subscription is only $5, but I never felt the need to buy it because the free tier does the job perfectly.
The Magic of Planning Mode & Auto-File Generation
One feature that absolutely blew my mind is the Planning Mode. When you give it a prompt, it doesn't just blindly start writing code. It goes into planning mode, thinks for a while, and creates a proper structure. After that, it automatically generates everything for you. It creates index.html, CSS, JavaScript files, UI animations—everything, automatically. You don't have to manually create files; it handles the entire project structure on its own.
Custom APIs, Web Automation & Live Research
If you have your own API keys, you can easily connect them. For instance, if you have a Claude API subscription or a free Groq API, you can add them directly. Inside the terminal, you can type a forward slash / to open the help menu, add subscriptions, or switch between modes like Interview Mode, Plan Mode, Review Mode, and Bash Mode. You can even change themes.
But here is the insane part: it can use your browser. If you have Google Chrome installed, the agent can perform Web Automation. For example, it can go to Amazon.com and add a product to your cart. If the browser isn't installed, it can still research live data from the internet, like finding the current Dollar to PKR exchange rate or various live statistics. Uploading files for context is also incredibly easy.
My Personal Projects with Free Buff
I have been using this tool for a long time and built several real-world projects. One of my favorites was building a laptop monitoring tool. I connected it to a WhatsApp agent, and it worked flawlessly. Free Buff makes automation so easy that you can build complex systems without writing hundreds of lines of code manually. It is truly the ultimate free alternative to Claude Code and Cloud Code.
