A smaller Mermaid Chart, for people who don't need Mermaid Chart.
If Mermaid Chart is load-bearing for you, don't switch. You'll find this thinner and you'll be right. Write Mermaid syntax, see a live rendered diagram, export as SVG/PNG. It comes with 52 other tools for $19.99/mo — which is the argument, not that it beats a product with a team behind it.

How much does Mermaid Chart cost?
About $0 a month, which is $0 a year, on the plan most individuals end up on. It is what we use in our own arithmetic — the list-price figure on the front page is the sum of these, not a round number we liked.
What do you actually get in VibeBundl?
- Write Mermaid, see it render live
- Save named diagrams
- Export SVG and PNG
What do I lose by replacing Mermaid Chart?
Honestly, these. If any of them is load-bearing for you, keep paying — a bundle that costs you a workflow isn't a saving.
- Real-time collaboration on one diagram
- AI-generated diagrams from a prompt
- Confluence and Jira embeds
Is there an open-source alternative to Mermaid Chart?
Yes — Mermaid Live Editor. If you're happy running and updating your own server, it will take you further than our version will, and it's free. VibeBundl's argument isn't that it's more capable than Mermaid Live Editor; it's that it's already running, and so are 52 other tools, on one login.
What's the catch?
It's smaller. 53 tools built by one person do not match 53 funded products, and we're not going to pretend otherwise. Each one covers the job you opened the original for and stops there.
So the honest pitch isn't “cancel Mermaid Chart”. It's that the next time you need something like it — once, briefly — you already have it, and you don't start another subscription to find out.
