Sometimes a piece of software makes you smile. Not because of flashy marketing or a long feature list, but because you can feel the care behind it. Excalidraw is one of those tools. So is Blender. So is Obsidian. We're living through a golden age of open source software, and it's worth taking a moment to celebrate.
These projects share something special: they prove that open source doesn't mean ugly or hard to use. They're often more delightful than their commercial competitors. And they respect you, your data, and your time.
Excalidraw: sketching without pressure
Excalidraw feels like drawing on a napkin. The hand-drawn aesthetic removes the pressure to make everything perfect. You can think out loud, iterate quickly, and share ideas without friction. It's collaborative, it's fast, and its file format is completely open. This is exactly what open whiteboarding standards should look like.
Blender: from underdog to industry standard
Blender's story is remarkable. A decade ago, it was a scrappy alternative for hobbyists. Today, it's used by major film studios and game developers. The software improved relentlessly, the community grew, and now it rivals tools costing thousands of dollars. Blender proves that open source can compete at the highest level.
Obsidian: your thoughts, your files
Obsidian sparked a renaissance in personal knowledge management. Your notes are just Markdown files on your computer. No lock-in. No subscription required to access your own thoughts. The plugin ecosystem is vibrant, built by people who use the tool every day. This is why open document standards matter: your work belongs to you.
What these projects share
Great open source tools tend to have a few things in common. They respect your data by using open formats. They respect your attention by staying focused. They're built by people who use them, which shows in every design decision. And they create communities, not just user bases.
There's also something different about how these tools evolve. Without pressure to ship features for quarterly earnings, they can focus on getting things right. They can say no to bloat. They can prioritize craft over growth metrics.
Why this matters for documents
At the Open Document Alliance, we're building infrastructure: parsers, converters, and specifications. But infrastructure only matters if people build great tools on top of it. Every time an Excalidraw or a Blender succeeds, it validates the approach. It shows that open can win. As we explore in why tech ecosystems matter, these successes create space for more open tools to flourish.
We're especially excited about what happens when open source meets AI. Well-structured, open data is exactly what AI tools need to work well. Projects that embrace open formats today are positioning themselves to benefit from AI innovations tomorrow.
How to support the movement
If you love these tools, there's plenty you can do. Use them. Tell others about them. Star repos on GitHub. Contribute documentation, bug reports, or code if you can. When evaluating new software, ask the important questions: Can I export my data? Is the format documented? Will my work survive if this company disappears?
The open source community is building something remarkable. Excalidraw, Blender, Obsidian, and countless others are proof that we don't have to choose between open and delightful. We can have both. And that's worth celebrating.
