Nix at scale

Nix that stays fast as you grow

Determinate Nix is built for the largest Nix deployments. Lazy trees and parallel evaluation cut evaluation time and disk usage in massive monorepos, pre-resolved store paths skip the evaluation tax on constrained machines, and FlakeHub Cache shares artifacts across every laptop, CI runner, and production host, so nothing gets rebuilt twice no matter how big you get.

Docs: Lazy trees

Lazy trees

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

Docs: Parallel evaluation

Parallel evaluation

Nix's evaluator has always been single-threaded. Determinate Nix distributes evaluation across every CPU core, cutting evaluation time by 50% or more on multi-core machines.

Announcement: WebAssembly in Nix expressions

WebAssembly in Nix expressions

Offload heavy evaluation logic, like parsing complex or niche file formats, to fast, sandboxed WebAssembly, so that demanding builds aren't bottlenecked by the Nix language itself.

Pre-resolved store paths

Fetch a flake output's store path from FlakeHub without evaluating it locally, so constrained devices and large fleets can pull from cache without paying the evaluation tax.

FlakeHub Cache: Shared binary cache

Shared binary cache

FlakeHub Cache shares Nix artifacts across every developer laptop, CI runner, and production host, so nothing gets rebuilt more than once.

Docs: Automated garbage collection

Automated garbage collection

Intelligent store management keeps disk usage in check across CI and fleets. Schedule GC runs to reclaim space without manual intervention or pipeline failures.

What reproducibility means: Reproducible on every machine

Reproducible on every machine

The same build on every laptop, CI run, and production host, so scaling out never means drift between environments.

One-line install across your fleet

The Determinate Nix Installer onboards thousands of machines with a single command, zero configuration, and an install that survives every OS update.

Federated authentication: Organization-wide access control

Organization-wide access control

Federated authentication and a fine-grained policy engine scope access for every user, device, and CI pipeline as your team grows.

Never troubleshoot Nix alone

At scale, a Nix slowdown or breakage can stall every team at once, and it can't wait on GitHub issues. Enterprise Nix Support gives you contractual SLAs, a dedicated Slack channel, and direct access to the engineers who built Nix, so your platform stays fast and resilient as you grow.

  • Issue investigation within one business hour, backed by service credits
  • A shared, dedicated Slack channel for real-time support
  • Direct access to Nix experts, including Eelco Dolstra
  • Annual architecture and security hardening reviews
