What Cachix does
Cachix is the operator of a Nix binary cache hosting platform, legally organized as the Estonian private limited company Enlambda OÜ and founded in 2018 by Domen Kožar. The service stores and serves prebuilt Nix build artifacts (NAR archives plus narinfo metadata) through a Cloudflare-fronted CDN, enabling developers and CI systems to share and retrieve identical binaries rather than recompiling them from source on every machine. Customers use the Cachix CLI to push, watch-store, watch-exec, and pull artifacts; CI integrations span GitHub Actions, GitLab CI, CircleCI, Buildkite, Hydra, Hercules CI, and Travis CI. Differentiated technical components include ZSTD compression by default (~100 Mbit/s push speeds), multipart uploads for large files, LRU-based garbage collection with a Pins feature for permanent retention, GitHub-org-based access control, and S3 import for migrating existing caches.
Beyond raw artifact hosting, Cachix has built Cachix Deploy, a pull-based continuous deployment product that connects websocket agents to Nix profiles on NixOS, nix-darwin, and Home Manager targets. Cachix Server for Enterprise offers a self-hosted deployment with SSO, SLA support, audit logs, and on-premise installation. The company reports 11,969 active developers, 7,613 hosted binary caches, and 521 TB transferred per month.
The business model is a freemium PLG subscription with a free 5 GB tier for open-source projects and tiered paid plans (Starter at 50 GiB, Standard at 250 GiB, Pro at 1500 GiB) plus multi-year self-hosted enterprise contracts on custom pricing. All paid plans include unlimited bandwidth via Cloudflare CDN. Go-to-market combines self-serve sign-up with direct sales for enterprise customers. Cachix is founder-controlled and primarily bootstrapped; the only disclosed external capital event is the Calm Company Fund investment in April 2020. Named customers include NoRedInk, Supercede, Scrive, Digitally Induced, and Scarf.

Cachix product offering
Product offeringCore offering
Cachix operates a Nix binary cache hosting platform that stores and serves prebuilt software build artifacts (NAR archives with narinfo metadata) so developers, CI pipelines, and deployment environments can share binaries instead of recompiling from source. The platform includes Cachix Deploy, a continuous deployment product for NixOS, nix-darwin, and Home Manager profiles using websocket-connected pull agents, plus an enterprise self-hosted Cachix Server option.
Product overview
Cachix provides a binary cache hosting platform for the Nix ecosystem. The core offering consists of Cachix (binary cache hosting) and Cachix Deploy (continuous deployment to Nix profiles). The Cachix CLI is the primary interface for all operations including pushing artifacts, configuring caches, and managing deployments. Cachix Server for Enterprise offers self-hosted deployment options. The platform uses NAR archives and narinfo metadata with Cloudflare CDN, supports multiple CI/CD integrations (GitHub Actions, GitLab CI, CircleCI, etc.), and provides S3 import for cache migration.

- Cachix Deploy: Continuous deployments to Nix profiles (NixOS, nix-darwin, Home Manager) using a pull model via agent daemons.
Products and services
- Cachix Binary Cache Hosting Hosted binary cache service for the Nix ecosystem that stores and serves prebuilt software build artifacts between CI, development, and deployment environments using content-addressed NAR storage, narinfo metadata, ZSTD compression, LRU garbage collection, and Cloudflare CDN for global delivery.
- Cachix Deploy Continuous deployment product for NixOS, nix-darwin, and Home Manager profiles that uses lightweight websocket-connected agents on target machines to pull binaries from the binary cache and activate deployments, eliminating local Nix evaluation or building.
- Cachix Server for Enterprise Self-hosted edition of the Cachix platform for enterprises that need on-premise or custom cloud deployment, with SSO, SLA support, dedicated support, custom storage, and audit logs.
Quantifiable outcome

Cachix competitors and assessment
Company assessmentDirect peers
- Determinate Systems: Direct peer in the Nix ecosystem offering Nix-installer, Flakes, and enterprise Nix tooling. Competes for the same Nix-developer mindshare and enterprise Nix adoption that Cachix serves, with overlapping value proposition around reproducible Nix-based infrastructure.
Emerging players
- Depot.dev: Build/CI acceleration platform that provides remote build environments and artifact caching. Targets the same developer pain point of long CI builds and shares the product-led growth and Nix-adjacent positioning, though broader than pure Nix binary caching.
- Earthly: Build automation and artifact sharing platform using Earthfiles to produce repeatable, cacheable builds. Competes in the build-cache and CI optimization space with overlapping developer persona and PLG distribution model.
- Jetify (formerly Devbox / Jetpack.io): Emerging player in reproducible development environments with Nix/Devbox heritage. Addresses similar developer pain points around reproducible builds and Nix-based tooling, partially overlapping with Cachix's audience.
Broad incumbents
- GitHub Packages: Broad incumbent artifact-hosting service bundled with the GitHub ecosystem. While not Nix-native, it provides general package and binary storage that competes for developer budget in adjacent supply-chain and CI workflows.
- AWS CodeArtifact: Broad incumbent managed artifact repository service from AWS. Competes with Cachix at the artifact-storage layer, especially for enterprise customers already on AWS, though without Nix-specific optimizations.
- Cloudflare R2: Broad incumbent object storage service from the same provider powering Cachix's CDN. Could absorb binary-cache workloads if Cloudflare extends Nix-aware features, and represents a structural dependency risk for Cachix.
- GitLab CI: Broad incumbent CI/CD platform with integrated artifact storage. While Cachix integrates with GitLab CI, the platform also competes for the same DevOps budget and could in principle add Nix-native caching features.
- CircleCI: Broad incumbent CI/CD platform with caching primitives. Competes for the build-pipeline and artifact-management budget that Cachix addresses, and is integrated with Cachix but also offers in-platform caching alternatives.
- Buildkite: Broad incumbent CI/CD platform with build-cache capabilities and artifact sharing. Overlaps with Cachix's CI integration footprint and competes for developer-tooling budget in build optimization.
