Scores
Popularity5/5
Broadly known
The default, most-recognized single-board computer for home labs and self-hosting, with the largest community and guide ecosystem of any option in this category.
Learning Curve3/5
Moderate
Basic setup (flashing an OS image, connecting to a network) is well documented, but running production-quality self-hosted services still requires real Linux administration comfort compared to a managed platform.
Flexibility4/5
Flexible
Runs any Arm-compatible Docker container or Linux service, from DNS filtering to home automation to small local models, though x86-only software and heavier workloads are out of reach.
Performance2/5
Below average
5-12 watts of power draw buys real but modest compute. Fine for lightweight always-on services, underpowered for VMs, 4K transcoding, or anything CPU-intensive.
Portability3/5
Some lock-in
Fully owned physical hardware with no vendor lock-in, but Arm architecture and hardware constraints (RAM, storage, networking) limit what workloads can move onto it versus a general-purpose VPS.
About Raspberry Pi
Raspberry Pi is a line of low-cost, credit-card-sized single-board computers and the default hardware choice for developers who want to self-host lightweight services without renting a VPS. The current Raspberry Pi 5 runs a quad-core Broadcom BCM2712 (Arm Cortex-A76) at 2.4GHz with 1GB to 16GB of RAM. It draws about 5-12 watts under load and 2-3 watts at idle, so running one around the clock typically costs a few dollars a month in electricity.
That power profile is what makes it a popular always-on home server: common workloads include Pi-hole (network-wide ad and tracker blocking), Home Assistant (home automation), WireGuard (a personal VPN), and lightweight Docker containers, including small local models through Ollama on the higher-memory boards. It is not the right choice for everything: virtual machines, 4K video transcoding, and x86-only Docker images run poorly or not at all on its Arm architecture.
As hardware, it has no license or subscription: the cost is a one-time purchase plus electricity, unlike rented VPS and cloud compute. Memory-driven price rises since late 2025 have nearly doubled the price of the 4GB and 8GB boards and more than doubled the 16GB board compared with launch, so a used x86 mini PC (Intel N100-class) now often matches it on price and beats it on performance for general-purpose home-server work. The Pi still wins on power draw, size, and its enormous community.
Key Features
- Credit-card-sized single-board computer, current generation is Raspberry Pi 5
- Quad-core Broadcom BCM2712 (Arm Cortex-A76) at 2.4GHz, 1GB to 16GB RAM options
- 5-12 watts under load, 2-3 watts idle, roughly $3-8/month in electricity for 24/7 operation
- Popular self-hosted workloads: Pi-hole, Home Assistant, WireGuard, lightweight Docker, small local models via Ollama
- One-time hardware purchase, no recurring hosting bill
- Arm architecture, not suited to VMs, 4K transcoding, or x86-only Docker images
Pros
- Lowest ongoing cost of any self-hosting option: a few dollars a month in electricity versus a recurring VPS bill
- Enormous community and documentation base for self-hosting guides and pre-built images
- Physical ownership means no vendor lock-in, no account suspension risk, and full control over the hardware
- Genuinely capable for its power draw on lightweight always-on workloads (DNS filtering, home automation, VPN)
Cons
- Arm architecture rules out x86-only Docker images and makes VMs and 4K transcoding impractical
- A used x86 mini PC often matches or beats it on raw performance for general Docker/NAS workloads at a similar price
- Memory-driven price rises (the 16GB board is up from $120 at launch to $305) have narrowed its cost advantage
- Requires physical setup, storage (SD card or SSD), and networking that a cloud VPS handles for you

Tech Stacks with Raspberry Pi
WordPress Self-Hosted
Infrastructure
InfrastructureThe CMS behind the open web on your own server: WordPress with its own database (MariaDB by default; MySQL equally supported) and Docker, with any plugin and any theme, and no managed-WP vendor in sight.
OpenClaw Self-Hosted
InfrastructureRun OpenClaw, the open-source personal AI agent, in Docker on your own server or home hardware. It answers in the messaging apps you already use, thinks with a model such as Claude or OpenAI, and stays closed to the internet, with its dashboard reached over an SSH tunnel.
Hermes Agent Self-Hosted
InfrastructureRun Hermes Agent, Nous Research's open-source agent that writes its own skills as it works, in Docker on your own server or home hardware. It answers in your messaging apps, runs on a low-cost model such as DeepSeek or a frontier one such as Claude, and keeps its dashboard private behind an SSH tunnel.
Tools Related to Raspberry Pi
Works well with Raspberry Pi(3)
Metabase's official Docker image ships ARM64 builds, making a Pi 4 or 5 a workable small-scale Metabase host.
Grafana is one of the most common self-hosted services on Raspberry Pi, with an official install guide on grafana.com.
A Raspberry Pi 5 with enough RAM can run Ollama and small open-weight models locally, a common lightweight self-hosted AI setup alongside services like Pi-hole and Home Assistant.
Alternatives to Raspberry Pi(3)
A Raspberry Pi at home costs its purchase price plus electricity; a Hetzner VPS costs a few euros a month but brings a datacenter connection, a public IP, and far more headroom. Pick the Pi for private, low-traffic services and the VPS for anything that must stay reachable.
A Raspberry Pi is hardware you own and maintain at home; Hostinger rents a VPS with one-click app templates and support. The Pi wins on running cost and keeping data on your own premises, the VPS on uptime and bandwidth.
A Raspberry Pi is a one-time purchase that runs hobby workloads at home with no monthly bill; DigitalOcean Droplets are on-demand servers with managed databases and one-click images. Choose DigitalOcean when the service needs reliability and room to grow.
