Mermaid Has a New Home — Here’s What That Means for the Open-Source Project
• 2 mins
If you’ve been using Mermaid for a while, you might have noticed that everything now lives at mermaid.ai. Here’s what’s changing.
The short version
The open-source Mermaid library and our commercial platform now live under one roof at mermaid.ai. The library is still free. It’s still open source. It’s still yours.
The longer version
Mermaid started as a community project, and that’s not something we take lightly. Thousands of developers rely on it, contribute to it, and build on top of it — and that community is the reason Mermaid is what it is today.
What it actually means in practice: docs that stay up to date, a faster path from bug report to fix, and a team that’s directly invested in the library’s health. The open-source project benefits from the same resources as the platform — because one can’t thrive without the other.
The commercial platform exists because it lets us sustain and grow the open-source project. That relationship goes both ways: a stronger library makes a better platform, and a better platform funds a stronger library.
What’s actually changing
The URL. That’s mostly it. The GitHub repo stays the same. The license stays the same. The contributor process stays the same. If you’ve built something on Mermaid, nothing breaks. If you contribute to Mermaid, nothing changes about how you do that.
What we’re committed to
Open source isn’t a footnote for us — it’s the foundation. We’re committed to keeping the library free, the roadmap visible, and the people who built Mermaid into what it is at the center of where it goes next.
