Fabrik

Open-source, multi-layer build cache infrastructure for modern build tools.

🎯 What is Fabrik?

Fabrik is a technology to build transparent, high-performance caching infrastructure for any build tool with remote caching capabilities. It provides a three-tier caching hierarchy (hot, warm, cold) that transparently accelerates builds across local development, CI/CD, and team environments.

Think of it as: The narrow waist between build tools and cache infrastructure—a minimal, universal interface that any build tool can plug into, and any storage backend can support.

🚀 Quick Start

1. Install Fabrik

Using Mise (recommended):

mise use -g ubi:tuist/fabrik

Or download from GitHub Releases

2. Set Up Shell Integration

Bash:

echo 'eval "$(fabrik activate bash)"' >> ~/.bashrc
source ~/.bashrc

Zsh:

echo 'eval "$(fabrik activate zsh)"' >> ~/.zshrc
source ~/.zshrc

Fish:

echo 'fabrik activate fish | source' >> ~/.config/fish/config.fish
source ~/.config/fish/config.fish

3. Initialize Your Project

cd ~/your-project
fabrik init

That's it! Your builds will now use the cache automatically.

✨ Key Features

• 🔥 Transparent Caching: Three-tier hierarchy with automatic fallback
• 🔧 Universal Compatibility: Supports Gradle, Bazel, Nx, TurboRepo, sccache, BuildKit, and more
• ⚡ High Performance: Built in Rust with RocksDB for ultra-low latency (<10ms p99)
• 🎯 Zero Configuration: Automatically detects CI environments

🏗️ Architecture

Fabrik implements a three-tier caching strategy:

1. 🔥 Hot Cache - Local/CI, ultra-fast (<5ms)
2. 🌡️ Warm Cache - Shared team cache (~20ms)
3. ❄️ Cold Cache - S3-backed permanent storage (~100ms)

Cache misses automatically fall back to the next layer. Writes propagate through all layers.
