Overview
HotBuilder is a powerful Unity Editor extension that lets you build your projects in the background without freezing or blocking the editor. Ideal for large projects and teams that need to stay productive, it allows you to continue working, testing, and navigating the editor even while a build is running.
No more waiting for builds to finish. Just queue your profiles, hit build, and keep creating.
Key Features
- 🚀 Non-blocking builds – Editor stays responsive while building.
- 🔁 Build Queue System – Batch multiple profiles and build them one after another.
- 🧠 Build Size Estimation – Know your build size before hitting "Build" using smart estimations per platform, asset type, and compression level.
- 📁 Smart Output Paths – Auto-folder naming by product, platform, version, or date.
- 🕹️ Runtime Build Executor – Build any project without opening the Unity Editor using bash script.
- 📊 Build Tracker Integration – Detect and offload regular Unity builds into background mode automatically.
- 🔧 Pre/Post Build Hooks – Run custom methods before/after builds.
- 📦 Auto Versioning – Supports auto-incrementing version numbers.
- 🔍 Live Build Logs – View and filter build logs inside the editor.
- ⚙️ CI/CD Support – One-click GitHub Actions workflow generation.
- 🧠 Profile Presets – Create, reorder, and customize build profiles per platform.
Bonus: Build Size Estimator
Estimate final build size before you commit. It analyzes scenes, assets, Addressables, managed code, shaders, streaming assets, and more—then applies platform-specific compression factors (like IL2CPP or Android texture compression) for accurate results. Great for optimizing mobile builds.
Is It Customizable?
Yes. Everything from output paths and platform settings to log filters and compression presets is customizable. Includes support for custom scripting hooks and build automation pipelines.
