The record

Product: Cachix is a service for hosting Nix binary caches.
Purpose: Cachix shares binaries between CI, development, and deployment environments.
CLI: The Cachix CLI can push binaries, watch a Nix store, and configure Nix to use a cache.
Cache performance: The service says its optimizations speed up binary cache roundtrips and Cloudflare CDN enables performance and unlimited bandwidth on all plans.
Storage management: When a cache reaches its storage limit, least recently used entries are removed; the pricing page says a warning email is sent at 85% of the limit.
CI integrations: The documentation provides CI guides for GitHub Actions, Buildkite, CircleCI, GitLab CI, Hercules CI, Hydra, and Travis CI.
Deployment: Cachix Deploy continuously deploys to Nix profiles such as NixOS, nix-darwin, and Home Manager using a pull model.
Access controls: Team members can be granted read and/or write access to a cache, and access tokens can be revoked at any time.
Cache security: Private cache reads and writes require an access token, and binary cache entries are signed using a managed or self-signed key.
Enterprise: Enterprise options include on-premise or self-hosted deployment, SSO, SLA and dedicated premium support, custom deployment, and audit logs.
Support: Cachix lists live chat, email, GitHub issues, and a service status page as support or feedback channels.
Security reporting: Cachix says it acknowledges vulnerability reports within 5 business days, aims to resolve confirmed issues within 90 days, and does not offer a paid bug bounty.
Company: Cachix was launched in 2018 by Enlambda OÜ to accelerate Nix adoption through infrastructure and education.
Founded: 2018
