## [Kiri: a Docker-compatible container runtime for three OSes](<https://sebastien.rigaux.be/en/tech-watch/links/kiri-a-docker-compatible-container-runtime-for-three-oses>)

Kiri replaces Docker Desktop and OrbStack with a lightweight container runtime for macOS, Windows, and Linux, compatible with the Docker CLI, Compose, and buildx. The repository also describes a native UI and support for Kubernetes clusters and Linux machines.

Its architecture uses a Linux VM and a Rust agent that starts containers through `clone3`, without runc, a shim, or dockerd. The project publishes startup-time benchmarks against Docker Desktop and OrbStack, along with instructions for reproducing them.

## [Zerobyte automates Restic backups for self-hosters](<https://sebastien.rigaux.be/en/tech-watch/links/zerobyte-automates-restic-backups-for-self-hosters>)

Zerobyte brings scheduling, management, and monitoring of encrypted Restic backups into a web interface. It supports NFS, SMB, WebDAV, and SFTP sources as well as local directories, with destinations including S3, GCS, Azure, and rclone.

The Docker Compose setup can be pared down when backing up only already-mounted directories: removing `SYS_ADMIN` and the FUSE device reduces the container’s granted capabilities, but prevents direct mounting of remote shares.

## [BillionMail: self-host an email platform and campaign workflow](<https://sebastien.rigaux.be/en/tech-watch/links/billionmail-self-host-an-email-platform-and-campaign-workflow>)

BillionMail combines a mail server, newsletters, and email marketing in an open-source, self-hosted package. Its repository outlines a setup flow connecting a domain and DNS verification to campaign creation and sending, with list and tag management.

The project supports Docker and installation through aaPanel. It also integrates RoundCube for webmail, offers delivery analytics, and is licensed under AGPLv3; the team running it remains responsible for hosting the service.
