Best Open Source Projects for Home Labs in 2026

What it is: a free platform that splits one computer into several small, isolated computers. Each one is called a virtual machine (VM) or a container.

Proxmox is the default home lab hypervisor in 2026 for a good reason. You can test something risky, break it, and delete it without touching your real setup. It also pairs with Proxmox Backup Server, which makes restoring a machine a click instead of a weekend project. The current line is Proxmox VE 9.2, built on Debian 13, and an ARM64 installer arrived in August 2026.

Use it when you want separate machines for media, photos, and experiments. Skip it if you have one PC and five apps. In that case plain Debian with Docker is simpler and just as capable. Good alternatives are XCP-ng and Incus.

What it is: a storage system that protects your files across several drives. It checks data for silent corruption and repairs it automatically using a file system called ZFS.

The 2026 story is finally simple. TrueNAS has moved its apps to Docker, and the old CORE branch is retired. That means the apps you already know how to write will run here. The current release is the 25.10 line, with a 26 version in testing. Because the storage rules are strict, check the current documentation before you move a large photo library across.

Use it when photos and movies actually matter to you and you own two or more large drives. Skip it with a single drive, where plain folders plus a real backup are better. Simpler alternative: OpenMediaVault. Expert alternative: Debian with ZFS by hand. Unraid is paid and closed, so it is not our pick.

What it is: an open router and firewall that gives you clean rules, guest networks, and network-level ad blocking.

OPNsense gets a release every January and July, and the 26.7 line is current. It is the calm open source choice for people who want control without paying for a firewall licence.

Use it when you want real traffic rules and a separate network for guests and smart devices. Skip it if your home network is one router and a few phones, where a cheap OpenWrt access point plus Pi-hole covers you. Keep your ISP box as the first router while you learn, change one rule at a time, and keep an Ethernet cable handy as an escape hatch.

What it is: Docker packs each app into its own tidy box. Dockge is a simple web page that starts and stops those boxes without a wall of terminal commands.

This is the pair that makes everything else on this list painless. Each app gets one small text file, called a compose file, that describes how it runs. You can read it, back it up, and delete it cleanly. Portainer is a capable alternative, and Komodo is a strong pick once you have more than one machine, but Dockge is the easiest place to start.

Install Docker on Debian, add Dockge, open it in your browser, and start one test app. Then immediately stop and remove that test app. That last step teaches you that nothing here is permanent. Save a copy of your compose files to a USB drive once a month.

What it is: a filter for DNS, which is the phone book of the internet. When a device asks where an ad server lives, Pi-hole answers with nothing.

Pi-hole 6 rewrote its core engine and now includes its own web server, so installation is lighter than it used to be. The result is fewer ads in browsers and apps across every device on your network. It does not do much inside the YouTube app, which is normal for DNS filtering, not a fault.

Install it, give the box a fixed address, then point your router's DNS setting at it. Test with one phone before you change everything. If a website breaks, allow that site in the Pi-hole dashboard and reload the page. Phones that use private DNS or a VPN will skip Pi-hole, so turn private DNS off at home if you want full coverage. AdGuard Home is an equally good alternative with a friendlier dashboard. Pick one, never both.

What it is: a front desk for your apps. Instead of remembering 192.168.1.40:8096, you type movies.home and get a padlock in the address bar.

Caddy is our pick because it fetches and renews HTTPS certificates by itself from a short, readable config file. Nginx Proxy Manager is the better choice if you would rather click buttons than edit text. Traefik is powerful if you already know it. Pangolin is a newer option worth a look for remote access.

Keep this layer on your home network first. Do not open ports 80 and 443 to the wider internet unless you truly need to. For remote use, a tunnel is safer than a raw open port, and we cover that in project 18 below.

What it is: two ways to make DNS private and fast. Unbound looks up addresses itself instead of forwarding them to Google or your internet provider. Technitium is a full DNS server with encrypted lookups and per-network rules.

Pair either one with Pi-hole later. Pi-hole becomes the ad filter, and Unbound or Technitium handles the lookups underneath it. This is an optional layer, not a starting point. Set it up only after your basic Pi-hole works.

What they are: two safe ways to reach your home apps from outside. Headscale is an open control server for the Tailscale client, so your phone, laptop, and server join a private network only they can see. Cloudflare Tunnel makes a single app reachable through Cloudflare without opening a port on your router.

Use a tunnel when you want to share one service or reach it from a browser. Use Headscale when you want your own devices on one private network. Do not do both on day one, and never expose a raw port just to check on your server. If you only want a quick private link for two machines, our guide to making your own VPN is a gentler start.

What it is: local control for your lights, plugs, sensors, and remotes, with no cloud in the path.

Home Assistant ships a new release every month, and the 2026.9 line is current. It works with thousands of devices from dozens of brands and keeps working when the internet is down. The easiest install is Home Assistant OS on its own box or virtual machine, with a Zigbee stick added for bulbs and sensors.

Install it, add one room, add one light or plug, and build a single automation. Then take a backup before you add anything else. If you are starting from scratch, our smart home upgrade guide walks through the gear side.

What it is: your own movie, show, and music server. It is like Plex, except the core is fully open and free of paid tiers. The current major version is Jellyfin 12.

An Intel processor with Quick Sync is a real advantage here, because it converts 4K video for your phone without loading the main CPU. Keep your media on the big hard drive, never on the small system SSD. If you also care about music, books, or comics, Jellyfin can share the shelf with the tools in project 17.

Make folders for Movies, Shows, and Music, install Jellyfin in Docker, and add one folder first. Check playback on your TV and your phone before you scan the whole library. If you are choosing a first box for this, our Raspberry Pi project ideas covers what runs well on cheap hardware.

What it is: your own Google Photos. It backs up your phone's camera roll, finds faces, and builds memories, all on your hardware.

Immich is the single most important addition to any 2026 list, and older guides still miss it. The project moves fast, with the 3.2 line current as of September 2026. Version 3 needs a processor that supports the x86-64-v2 instruction set, which the machine-learning (ML) features rely on. Intel users can speed up those features with OpenVINO, and the docs cover the image tags for it.

Set the upload folder on your big disk and the database folder on a fast disk, then install the official compose stack. If you are moving away from Google, our Google Photos wallpaper trick is a fun way to reuse what you already have. Two honest warnings: back up the database and the photo library together, and never switch hosts without exporting first.

What they are: Nextcloud is Drive, Docs, Calendar, and Contacts in one package. Syncthing only syncs folders, and it does that one job extremely well. Syncthing is on its version 2 line, and Nextcloud is on version 35.

The rule is simple. If you want files on two PCs, use Syncthing. If you also want shared calendars and contacts, use Nextcloud, and accept that it is the heaviest app on this list. Most homes are happier starting with Syncthing plus a simple file browser. Add Nextcloud later only if the calendar need is real.

What it is: a lightweight password server that works with the official Bitwarden apps on every device you own.

One honest note before you install it: Vaultwarden is an independent, unofficial server that speaks the Bitwarden protocol. It is widely used and trusted by the community, but it is not made by Bitwarden. Treat it accordingly.

Run it in Docker, keep it on your home network at first, turn on two-factor authentication, and export a backup to a USB drive. Write your one master password on paper and store it somewhere physical. That paper copy is the difference between a forgotten password and a locked vault.

What it is: a local camera recorder that understands what it sees. It can tell a person from a car or a pet, and it sends alerts without a monthly fee. The current release is Frigate 0.18.

The cost here is hardware, not software. Video eats disk space quickly, and smart detection runs far better with a Coral accelerator or a capable graphics chip. Before you buy cameras, count them and note the resolution, then size a disk for seven days of footage. Add one camera, let it run for a day, and only then add the rest. ZoneMinder is the older alternative, and Scrypted is strong if you care about Apple HomeKit, but Frigate is the clean pick for a new build.

What it is: automation that runs on your box. When Immich adds a new photo, send a message. When a disk fills up, send an alert. When a form is submitted, add a row to a sheet. The current line is n8n 2.x.

One licence note, because this list is strict about it: n8n is fair-code, not fully open source. Its Sustainable Use License is fine for personal use and most small businesses, but it is not an OSI-approved open licence. We include it because many readers already run it and we cover it in depth. If that matters to you, Node-RED and Activepieces are open alternatives.

Install it in Docker, build one flow with two steps, and run it by hand. Only switch it to automatic after it succeeds three times in a row. We already publish what n8n is, how to self-host n8n, and the best n8n workflows.

What it is: a ChatGPT-style chat that runs entirely on your own machine, with nothing sent to a company.

Ollama is genuinely open under the MIT licence. Open WebUI, the friendly chat interface on top, recently added a branding clause, so it is now source-available rather than fully open. For personal use this changes nothing, but the list is honest about it.

Memory is the whole story here. 8GB is enough to start with a small model, and 16GB to 32GB is smooth in 2026. It also draws real power, so leave it off a Raspberry Pi. Install Ollama, pull one small model, open the web interface, and ask three test questions while watching memory use. For a deeper look, see our guide to running Gemma 4 on your own hardware and setting up OpenClaw.

Two projects share this slot, so choose based on the pain you feel now.

Paperless-ngx scans bills, letters, and receipts into a searchable archive. It is on its version 3 line, and it is a quiet life-changer for any household that drowns in paper. If you mostly deal with PDFs, Stirling PDF is a handy open companion.

Forgejo is GitHub at home for your own code and notes, created after the Gitea community split, and now on version 16. Its home is Codeberg rather than GitHub. Gitea and GitLab CE are the alternatives, though GitLab is heavy for a home box. Do not install both projects at once. Pick the one you will actually use.

What they are: Uptime Kuma watches whether your services are up and pings you when one goes down. Beszel watches each machine's memory, CPU, and disk, and warns you before a disk fills.

This is the least glamorous entry and one of the most valuable. A home lab that fails silently is worse than no home lab, because you trust it. Start with Uptime Kuma pointed at three services, then add Beszel once your lab has more than one machine.

What they are: three focused servers that each do one media type better than a general tool. Navidrome streams your music collection. Audiobookshelf handles audiobooks and podcasts with proper progress tracking. Kavita is built for comics and manga.

Use them alongside Jellyfin or instead of it, depending on what you own. Each one is light and installs in minutes. Do not run two of them if Jellyfin already reads those files well.

What they are: the tools that turn a backup into something you can actually restore. restic and BorgBackup create encrypted, deduplicated backups you can send to a USB disk or the cloud. Proxmox Backup Server does the same job for whole virtual machines if you run Proxmox.

This is the most important entry on the page, and the least fun. restic is the easiest place to start. Borg is a strong alternative with a longer history. Set one up, schedule it, and then test a restore before you trust it. An untested backup is a rumour.
