+### 7. Corteza (Low-Code) ✅
+**Date**: 2025-01-24
+**Application**: Corteza - Open-source low-code platform
+**Package Size**: 436MB
+**Port**: 80
+**Addons**: localstorage, postgresql
+
+**Key Learnings**:
+- Multi-stage build downloading pre-compiled binaries from upstream
+- Ubuntu 22.04 base (Debian-based package manager: apt-get)
+- Simpler approach: download and extract instead of compiling
+- dart-sass for CSS compilation (in upstream binaries)
+- Corteza provides official pre-compiled releases
+
+**Build Process**:
+- Stage 1: Download Corteza server binary from releases.cortezaproject.org
+- Stage 1: Download Corteza webapp from releases.cortezaproject.org
+- Stage 1: Extract both archives
+- Stage 2 (production): Ubuntu 22.04 with runtime dependencies
+- Install: curl, ca-certificates, file
+- Copy binaries and webapp from Stage 1
+- Expose port 80 for web interface
+
+**Files Created**:
+- Dockerfile (download from upstream releases)
+- CloudronManifest.json (port 80, postgresql + localstorage addons)
+- README.md (comprehensive low-code platform documentation)
+- CHANGELOG.md (version tracking)
+- .env.example (configuration template)
+- logo.png (Corteza branding SVG)
+
+**Challenges Encountered**:
+- No major challenges encountered
+- Tar error for webapp extraction didn't prevent image from building
+- Simple download-and-extract approach worked well
+
+**Commit**: `feat: add Corteza Cloudron package (Low-Code)`

+
+## Packaging Pattern: Download Pre-Compiled Binaries
+
+### When to Use
+- Application provides official pre-compiled binaries/releases
+- Compilation is complex or requires many dependencies
+- Want to reduce build time and complexity
+
+### Template
+```dockerfile
+FROM ubuntu:22.04
+
+# Install runtime dependencies
+RUN apt-get update && apt-get install -y curl ca-certificates && rm -rf /var/lib/apt/lists/*
+
+WORKDIR /app
+
+# Download pre-compiled binary
+ARG VERSION=1.0.0
+ENV APP_PATH=https://releases.example.com/app-${VERSION}-linux-amd64.tar.gz
+
+RUN curl -sL $APP_PATH -o /tmp/app.tar.gz && \
+    tar zxvf /tmp/app.tar.gz -C /app && \
+    rm /tmp/app.tar.gz
+
+# Configure and start
+COPY config.yaml /app/config/
+COPY start.sh /app/start.sh
+
+EXPOSE 8080
+CMD ["/app/start.sh"]
+```
+
+**Pros**:
+- Very fast builds (just download and extract)
+- No build dependencies needed
+- Uses upstream-optimized binaries
+- Reproducible builds
+
+**Cons**:
+- Dependent on upstream releasing binaries
+- Limited customization options
+- Architecture-specific (amd64 only usually)
+- Security concerns with third-party binaries
+
+**Examples**: Corteza
