Today’s topics

rpkgs.com

  • Linux binary packages
  • Public build process
  • Powered by {bincraft}
  • R Consortium funded

ricochet (ricochet.rs)

  • Universal DS Deployment App
  • Alternative to Posit Connect, ShinyProxy, Faucet
  • Homelab & Enterprise scope

Part 1: rpkgs.com

rpkgs.com - The Problem

  • 2024: No distro-agnostic FOSS build process for Linux binary packages
  • R Universe: Ubuntu only (and for long time amd64 only)
  • r2u: Ubuntu only (& wrong concept: island solution, no multi-version)
  • bspm: System-package manager (& wrong concept: island solution, no multi-version
  • Posit Package Manager: proprietary, license restrictions, no arm64, no Alpine at this time

→ R needs a universal & unrestricted source for Linux binary packages for more distributions than Ubuntu (amd64)

rpkgs.com - Posit Binaries: Legal Restrictions

Posit’s Terms of Use restrict usage to internal purposes:

  • No use “for the benefit of any third party”
  • No inclusion in “service bureau, application service provider or outsourcing offering”
  • No “sell, resell, license, sublicense, distribute, rent or lease”

→ Building an app for R? You need an alternative binary source.

rpkgs.com - The Solution

R needs a sovereign, community-powered build chain:

  • Usable everywhere without restrictions
  • All common1 Linux distributions for Data Science
  • Both amd64 AND arm64 architectures
  • Open build process

→ rpkgs.com

rpkgs.com - Supported Platforms

Distribution Versions Arch
Ubuntu 2 (last two LTS) amd64, arm64
RHEL / Alma / Rocky 3 (last three majors) amd64, arm64
Alpine (MUSL!) 3 (last three releases) amd64, arm64

→ 8 distro/version builds × 2 arch = 16 build targets per R version

rpkgs.com - By the Numbers (2026-01)

3.0+ TB Total Size

2.0M Binary Packages

16 Build Targets

rpkgs.com - Alpine R Container Images

  • Alpine is the OS for CICD
  • CI commonly uses containers
  • Multiple version combinations needed

devxygmbh/r-alpine

  • Rebuilt weekly
  • R: 4.1 – 4.5
  • Alpine: 3.21 – 3.23

→ Preconfigured with cran.rpkgs.com

docker run --rm -it devxygmbh/r-alpine:4-3.23 R -q -e 'getOption("repos")'
> getOption("repos")
                                           CRAN
"https://cran.rpkgs.com/arm64/alpine323/latest"

rpkgs.com - Infrastructure

Build Servers 1 (Geekbench 6)

Machine Arch SC MC
Hetzner AX42 (16c, 64GB) amd64 2849 13063
Mac Mini M4 (10c, 32G) arm64 3714 20708
Lenovo T14 gen6 (6c, 16GB) amd64 2657 8757

Distribution

  • CDN via Bunny — 10$/TB traffic (1/9 of AWS)
  • Universal repo with auto-detection: cran.rpkgs.com

rpkgs.com - Challenges

Technical

  • Alpine: C++ R packages often fail because of MUSL
  • Exotic system dependencies
  • Some packages need manual fixes

External Dependencies

R Consortium funded project — but the project still needs people to run it! Help welcome!

Help Out

  • Spread the word
  • Report build failures to package maintainers
  • Contribute fixes for Alpine/MUSL
  • Donations help to cover infrastructure costs

Part 2: ricochet

ricochet - The “Problem”

Hypothesis: No “modern” and “affordable” DS deployment platform exists.

App Owner Issue
Posit Connect Posit 20k–70k/year, no free/homelab tier
ShinyProxy OpenAnalytics Free but tedious config, limited RBAC, Java
faucet ixpantia No shared cache, no UI, prebuilt images, no RBAC
Shiny Server Open Source Posit Barely maintained, very basic, no RBAC


→ Need: App for homelab + enterprise, “fair” enterprise pricing, dependency cache, R/Python/Julia, RBAC

ricochet - Our Vision & Values

Data scientists are developers

  • CLI-first deployment
  • Git-based workflows
  • API-invokable tasks (scripts), language-agnostic

Homelab to Enterprise

  • Powerful core functionality for homelab
  • Mac and Windows compatible (Server & CLI)

Built for an evolving ecosystem

  • Shiny, Plumber, Ambiorix, …
  • If it speaks HTTP → deploy it

Your infra, your choice

  • Host, Docker, or Kubernetes
  • Julia, Python, R etc.

ricochet - Core Concepts

Architecture

  • Written in Rust
  • Self-hostable
  • Cross-platform CLI
  • Multiple backends:
    libcontainer (Host), Docker, K8s
  • Prodution-ready Execution Environments

App Features

  • UI with RBAC controls
  • Private/public apps
  • Scaling control
  • Shared dependency cache
  • Static site deployments
  • Scheduled tasks

ricochet - Current State

Timeline

  • Currently in (private) beta
  • First “prod” release: ~ June 2026

ricochet - Homelab vs Enterprise

Homelab (Community) Enterprise
Servers Single server Multi-server / clustered
Auto-scaling
App privacy Public only Public / Internal / Private
Users Up to 2 Unlimited
RBAC / Groups
Audit log & compliance
Git-based deployments Up to 5 Unlimited
Scheduled tasks Up to 5 Unlimited
Licensing Always-online Air-gapped supported
SSO & CLI deployments

More information at docs.ricochet.rs/admin/pricing/5-community-edition

Free for academia

Enterprise will be free of charge for research.

ricochet - What Sets Us Apart (Enterprise)


Self-service pricing (no “sales” calls, flexible adjustments)

Unrestricted number of users/viewers - guaranteed

Unlimited (public) app consumptions

Main pricing based on number of apps (in blocks)

One license for any backend (incl. Kubernetes)

Community and open discussion forum

Part 3: ricochet deployment demo

Coming up: paquetier

A self-hosted, CRAN-compatible package registry for R (and more)

Private & public R repos with RBAC
S3-compatible storage; multi-repo
Git-driven builds (tag/branch); optional binaries via {bincraft}
Web UI + CLI + REST API

→ A sovereign, self-hosted alternative to Posit Package Manager
