-Here's a list of open source tools that are almost too good to be true.
+I'm a huge fan of all things open-source. I've spent many hours exploring open-source software, and I've discovered so many fantastic tools and apps that have improved my workflows in so many ways. I want to share my personal favorites with this blog post.
+These are the open-source gems that I believe deserve a spot on everyone's computer. I hope you'll enjoy them as much as I do! Let's get started!

+## Design & Prototyping
+
+For the few times that I need to design something or prototype something visually, I found that using open-source tools helps me in saving costs for subscriptions or software itself.
 
 ### Penpot

+One of the open-source tools I've fallen in love with is [Penpot](https://github.com/penpot/penpot), a fantastic web-based design and prototyping tool that's perfect for UI and UX designers. It's a real game-changer for those of us who want an alternative to popular subscription-based design tools like Sketch and Figma.

+The thing I adore about Penpot is that it's not just powerful, but also user-friendly and incredibly versatile. You can design beautiful interfaces, create interactive prototypes, and even collaborate with your team in real-time - all from within your web browser! Plus, it supports all major vector and raster file formats, so you won't have to worry about compatibility issues.
+
+Another fantastic aspect of Penpot is the active and supportive community behind it. They're always working on improvements and adding new features, making sure we have the best possible experience.
+
+If you're a designer looking to dip your toes into the open-source world or just searching for a budget-friendly design tool, Penpot is definitely one to check out! Trust me, you won't be disappointed!
+
+### Excalidraw
+
+I've been loving Excalidraw lately, a fun and easy-to-use open-source whiteboard app that's perfect for brainstorming and sketching ideas. With its minimalistic interface, you can quickly create hand-drawn-like shapes, lines, and text, making your ideas come to life in no time.
+
+Despite its simplicity, Excalidraw offers powerful features, like real-time collaboration and easy sharing in various formats. Its open-source nature and supportive community ensure continuous improvements, making it an excellent choice for students, teachers, and professionals alike.
+
+If you're after a fun, user-friendly, and effective tool for visualizing your thoughts, Excalidraw is definitely worth a try!
