I use Incus and Proxmox for this, more mature and have quite a bit built around them. What does Containarium bring to the table compared to them?
Containarium is more of a "purpose-built, single-VM, SSH-first dev environment" approach:
- Lightweight: 1 VM can host 50–100+ LXC containers - Quick provisioning: seconds instead of minutes per environment - Focused on SSH workflows and dev sandboxing, not full datacenter management - Minimal infra overhead: no GUI, no HA cluster required
Tradeoffs we’re aware of: - Shared kernel (not VM-level isolation) - Linux-only - Less built-in tooling compared to Proxmox
We designed it to *optimize for cost efficiency and rapid dev onboarding*, rather than full-featured virtualization.
Would love to hear if you see any pitfalls with this approach compared to using Proxmox/Incus in a single-host scenario!
In fact, it is just using the same technologies as LXC and Incus. (It is exactly LXC and Incus)
So really nothing special at all. Perhaps people looked at the title and rushed to the repo.
When I saw "IMPLEMENTATION-PLAN.md" and "SECURITY-CHECKLIST.md" filled with hundreds of emojis, I immediately closed the tab and now replying to you that it is total slop.
2026 is the year of abundant "not invented here syndrome".
We’re curious how you handled provisioning, isolation, and resource limits in your setup. More importantly, what’s the maximum scale you’ve been able to push?
