Pick Komodo for Git-driven deploys across many Docker servers from one screen. Choose Portainer if you run Kubernetes, which Komodo does not support. Pick Dockge for a single lightweight host. Komodo added a dedicated Docker Swarm resource in 2026, closing what used to be the single most-cited reason people held off, a complaint that once drew 168 votes on Reddit.

What is Komodo and what problem does it solve?

Komodo is an open-source tool that builds and deploys Docker software across many servers from one place. It is licensed under GPL-3.0 and written in Rust and TypeScript. The project lives at moghtech/komodo and was renamed from “Monitor” before the rebrand.

Picking a self-hosted database in 2026 comes down to one question: when does it force you to migrate? SQLite holds until about one write-heavy app server (~10 GB, single writer). PostgreSQL 18 is the default that almost never makes you move. MariaDB 12.3 LTS earns its spot mainly when you already live in the MySQL world.

What are the best self-hosted databases for web apps in 2026?

For a self-hosted web app, three engines cover almost every case: PostgreSQL is the do-everything default, SQLite is the embedded single-file engine, and MariaDB is the MySQL-compatible community fork. All three are open source and free to run on your own box.

The Orange Pi 5 Plus is the better self-hosting board for Docker-heavy workloads thanks to its 8-core RK3588 CPU, up to 32GB RAM, and dual NVMe M.2 slots. The Raspberry Pi 5 wins for beginners and single-service setups with its superior software ecosystem and community support. Both boards draw under 18W, run Docker containers on ARM64 without issues, and can be purchased for under $200 in their mid-range configurations. The right pick depends on how many services you plan to run and whether hardware expandability or software polish matters more to you.

Can your consumer router do WireGuard VPN at 800 Mbps, isolate IoT devices into separate VLANs, and kill bufferbloat with a single queue management setting? Stock firmware almost certainly cannot. OpenWrt can.

OpenWrt is a full Linux distribution that replaces the limited manufacturer firmware on compatible routers. The router ends up behaving more like a managed switch and enterprise firewall than the box your ISP sent you. The current stable release is OpenWrt 25.12.2 (March 2026), which introduced the apk package manager (replacing opkg) and now supports over 2,200 devices. Flashing typically takes five minutes and is reversible if you keep a backup.

The Short Answer

When Zigbee devices keep dropping, the culprit is almost always the mesh topology, not the sensors. Add mains-powered routers every 10 to 15 meters. Move the coordinator away from the WiFi router and any USB 3.0 port. Switch to Zigbee channel 15, 20, or 25 to dodge WiFi. Use the network map in Zigbee2MQTT or ZHA to spot weak links. Roughly 90% of complaints trace back to three things: too few routers, a coordinator in an RF hot zone, and a Zigbee channel that clashes with WiFi.

Deploy Prometheus to scrape metrics from node_exporter on each Linux server. Then chart it all in Grafana with CPU, memory, disk, network, and systemd service health. The full stack (Prometheus 3.x, node_exporter 1.10, Grafana 11.6) can watch a 10-server homelab on one Raspberry Pi 4 or a small VM with 1GB RAM. The community Node Exporter Full dashboard (Grafana ID 1860) gives you production-grade views in under 30 minutes.
