Determinate Nix is Determinate Systems' validated and secure downstream distribution of NixOS/nix. From package builds to development environments to deployments to running NixOS and beyond, Determinate Nix is feature rich, boldly innovative, and the standard bearer in the Nix ecosystem.

Performance that astounds, developer experience that delights

🍎

Native Linux builder for macOS

Build Linux packages with zero configuration or extra setup using macOS's built-in Virtualization framework. No more remote builders or cross-compilation, just Determinate Nix.

🌲

Lazy trees

Provides faster and less resource-intensive evaluation for many expressions involving flakes, even in massive monorepos. We've seen reductions in wall time of 3x or more and reductions in disk usage of 20x or more.

🤖

Parallel evaluation

Speeds up a wide range of Nix operations by distributing work across multiple processors. We've seen reductions in evaluation time of 50% or more.

🕸️

WebAssembly in Nix expressions

Enables you to cover a broad new range of potential use cases using the Nix language, like fast parsing of complex strings and niche file formats.

📐

Flake schemas

Make your flakes more extensible and discoverable by showing Nix how to handle non-standard output types.

❄️

Stable flakes

Upstream Nix remains uncommitted to flakes but we're all in on them, offering a formal stability guarantee and making flakes the default in Determinate Nix.

As a downstream distribution, Determinate Nix is fully compatible with and includes everything available in upstream Nix plus substantial upgrades (like those listed above). Determinate Nix makes Nix workflows faster, CI/CD runs smoother, and the overall experience of using Nix seamless across all environments.

Every Determinate Nix release is validated on SOC 2 Type II infrastructure and backed by a defined Common Vulnerabilities and Exposures (CVE) process, providing the security, scale, and stability that organizations need across developer workstations, CI/CD, and the cloud.

Nix for the modern enterprise
