Multi-tenant Nix Binary Cache

A decentralized binary cache for Nix over Git

Nix binary cache and build matrix for GitHub Actions: eval once, build checks in parallel jobs, deduplicated uploads, automatic GC, zero setup

Unpack and serve NAR file content on the fly

Nix substituter proxy with parallel cache queries and latency-aware selection

Self-hosted Nix binary cache: nginx + mTLS + GC-root-based pruning. No database, no daemon.

Self-host a Nix LRU S3 Cache (TF module)

Trim Nix binary caches according to GC roots

Cloudflare-native NixOS Binary Cache infrastructure.

Versatile and user-friendly binary data cache

The OCI-based Nix-Binary-Cache written in Go

The configurations for the attic-server image and for the fly.io deployment.

(OLD) binary cache server and distributed builds for Nix

The client-side agent and reproducer for Vega, a Nix binary cache verified by independent rebuilders.

Vega-operated reproducer: independently rebuilds attested outputs and attests the result (vega-repro lane).

Binary cache server for vcpkg: implements the vcpkg HTTP binary caching protocol with pluggable storage (filesystem, MinIO, S3, Azure Blob, GCS), a live web dashboard, Prometheus metrics and optional token or basic auth. Built with FastAPI.

Cloudflare Worker + R2 backed Nix binary cache (Rust) — fast substitutes without running your own cache server.

Prototype: Reference implementation and conformance suite for composable, downgrade-resistant signature authorization in Nix.
