Why not use Docker or other containerization tools instead of Nix?</strong></p> <p data-svelte-h="svelte-16vhgao">While Docker provides isolation and consistent runtime environments, it doesn’t guarantee fully reproducible builds. Factors like base image changes or implicit dependencies can still introduce variability.</p> <p data-svelte-h="svelte-1w64iyw">Nix focuses on reproducibility through deterministic builds, ensuring the same inputs always produce identical outputs.
