Blacksmith and Depot Colocate Docker Layer Cache on NVMe: What 40x Faster CI Builds Mean for Self-Hosted Build Pipelines
Blacksmith and Depot claim 20x-40x faster Docker builds by moving the layer cache onto NVMe disk colocated with the build machine. Here's the actual mechanism, and what it means for a self-hosted PaaS that already owns its build hardware.
CAPMOX Is Maturing Fast: What a Real Cluster API Provider for Proxmox Means Beyond Hetzner-Only Node Pools
IONOS's CAPMOX shipped six releases in fifteen months of active development — here's what the changelog actually shows, how it provisions a node, who else is building the same thing, and what a second CAPI provider really costs a Hetzner-only fleet.
Firecracker MicroVMs for Multi-Tenant CI: What Per-Build Kernel Isolation Actually Costs
A shared-kernel build pod runs a tenant's arbitrary install scripts and Dockerfiles next to every other tenant's. Firecracker microVMs can close that gap per build — real numbers from BuildBuddy's production fleet included — but per-step isolation, which nobody has actually shipped, is a different and much worse trade.
The Postgres Backup Tool Anthropic and OpenAI Both Backed in the Same Month
Databasus out-starred pgBackRest, WAL-G, and Barman in 14 months, landed in the official PostgreSQL Software Catalogue, and got backed by both Anthropic and OpenAI's open-source programs in the same month. Here's what it actually is, and whether it belongs next to a Kubernetes-native Postgres fleet.
Devin Outposts: Cognition Shipped a Kubernetes Operator Instead of a Bigger Cloud
Cognition's Devin Outposts keeps the reasoning in the cloud but moves command execution onto your own machines — and shipped a Kubernetes operator to run it. Here's exactly what devin-outpost-k8s deploys and what a Cluster-API fleet needs to add to host it natively.
Dokploy vs. Coolify in 2026: What Happens the Day You Click 'Add Server'
Coolify and Dokploy both added multi-server features in 2026. Neither provisions a machine, heals a dead node, or wires up a load balancer without a human at the keyboard. Here's the feature-by-feature gap against a Cluster API fleet.
eBPF Made Continuous Profiling Nearly Free — But Someone Still Has to Store It: Parca vs. Pyroscope on a Self-Hosted Fleet
Parca and Pyroscope both run eBPF-based continuous profiling under 1% CPU overhead. Here's what standing either one up as a Cluster API service actually costs in storage and operational surface, worked against Datadog and Grafana Cloud's own profiling bills for the same fleet.
Hetzner's ARM (CAX) Instances Won't Save You Money Until Your Build Layer Can Target Them
Hetzner's Ampere ARM (CAX) instances are pitched as cheaper per core than x86 CX. Current 2026 pricing says otherwise — and the real gate on ARM economics is whether your buildpacks pipeline can produce an arm64 image at all.
One Rack Switch Died in Nuremberg. Here's What a Hetzner Cloud Leaf Fault Actually Costs a Cluster API Fleet
On July 24, 2026, a switch fault in one Nuremberg rack took down Load Balancer, Networks, Cloud Server, and Object Storage together. What that actually costs a running CAPH cluster, why it's not a one-off, and the concrete mitigation CAPH exposes today.
