Blazing Fast
Generates thousands of pages per second thanks to a highly optimized pipeline and multi-threading.
Unix-First
Leverages native syscalls (inotify) for zero-latency filesystem monitoring and extreme performance.
Zero-Copy
Strictly avoids redundant memory allocations by passing pointers across a stateful DSL engine.
1.3 MB Binary
No dependencies, no node_modules. Just a single, tiny, statically linked binary ready to run.
Deterministic
Guaranteed consistent output across all builds. No race conditions, just predictable and stable generation every time.
Partial Hydration
Smart change detection only re-renders what is necessary, keeping developer feedback loops under 50ms.
The Discipline
Agreement.
Mustela isn't a framework. It's a high-performance stream engine. It doesn't have a safety net because safety nets have weight.
- Engineered for sub-millisecond throughput
- Direct HTML stream manipulation
- Zero-abstraction philosophy
- No automatic tag closing/validation
- Requires strict structural discipline
- Not recommended for beginners
Performance: The 5,000 Page Challenge
| Metric | Result |
|---|---|
| Files Processed | 5,000 Markdown files |
| Total Build Time | 528 ms |
| Throughput | ~9,470 pages / second |
| Peak RAM Usage | 34.6 MB |
| CPU Efficiency | 131% (Multi-threaded I/O) |
"Building 5,000 pages in half a second means your site is ready before your monitor can even finish its next refresh cycle."
Hybrid Content Power
A seamless transition from metadata to content that feels like writing a script, not just a document.
meta do
title: "Advanced Templating"
author: "Filip Vrba"
index: article
end
# Mixing Markdown & Mustela
This is standard Markdown text.
html do
<div class="special-callout">
<h4>Mustela Insight</h4>
<p>Reading a variable: <strong>@author</strong></p>
</div>
endModular Templating
This is where you define the structure. Mustela utilizes a stateful DSL, allowing you to compose HTML components with zero rendering overhead.
meta do
title: Mustela
index: main
end
html as main do
<!DOCTYPE html>
<html lang="@lang">
@html[head]
@html[body]
</html>
end
html as head do
<head>
<meta charset="UTF-8">
<title>@title</title>
@html[style]
</head>
end
html as body do
<body>
@html[header]
@view
<footer>
@title © @date_now
</footer>
</body>
endModular Ecosystem
Mustela isn't a silo. It's a high-performance core that generates clean, modern scaffolding ready for any stack.
Render content at sub-millisecond speeds with V, while letting Bun or Vite handle the heavy lifting of the modern JavaScript ecosystem.
