Snap is a modern package management and software deployment system developed by Canonical. It allows users to install, update and manage applications through self-contained packages known as snaps. These packages work across multiple Linux distributions, making software deployment simpler and more consistent. Key features of Snap packages include:
- Cross-distribution compatibility.
- Bundled dependencies.
- Automatic updates.
- Rollback support.
- Enhanced security through sandboxing.
- Easy installation and removal.

Snap vs. Apt
The following are the differences between snap and apt:
| Feature | Snap | APT |
|---|---|---|
| Compatibility | Works across multiple Linux distributions | Primarily for Debian-based distributions such as Ubuntu |
| Dependency Management | Bundles required dependencies within the package | Uses system-wide shared dependencies |
| Updates | Automatic updates with rollback support | Updates managed through the package manager |
| Security | Applications run in isolated sandboxes | Traditional package management with less isolation |
| Package Size | Usually larger due to bundled dependencies | Generally smaller because dependencies are shared |
| Startup Speed | Can be slightly slower for some applications | Typically faster startup times |
