Essential Homelab and Self-Hosting Resources

Every other project in this section teaches one specific build. This page is different: it's a map of the wider homelab and self-hosting world -- the communities, discovery lists, and tools that come up constantly once you start building, collected in one place instead of scattered across a dozen bookmarks.

How to use this page, and how entries were chosen

This isn't an exhaustive directory -- it's a curated starting point. An entry is here because it met at least one of: actively maintained (recent activity, not abandoned), a real stated license (not ambiguous "free to use" with no license file), a large enough community that questions actually get answered, or documentation good enough that you're not reverse-engineering behavior from source code. Where a project's status is uncertain or its activity level wasn't independently checked, that's stated on the entry rather than implied by omission.

Start-here paths, depending on what brought you here:

• "I want to stop paying for cloud subscriptions" → Reference lists (Awesome-Selfhosted) → pick one category (photos, notes, passwords) → the Comparison tables below for anything with multiple good options → the relevant DaemonPress Build guide if one exists
• "I want to learn networking or sysadmin for a job or certification" → Learning resources below, then the Build guides in this section for hands-on practice against the concepts you're studying
• "I have an old PC/server and no specific plan" → Communities below (ask what people do with similar hardware) → Hardware sourcing if you're thinking about adding more → the Proxmox cluster guide if virtualization is on the table
• "I already run things and want to do it better" → Comparison tables (see if you're using the right tool for the job) → Communities' more advanced discussion → this section's Security/Backup-focused Build guides as they're published

Communities

• r/homelab -- Reddit, hardware-focused: builds, rack setups, buying advice. Best for: hardware-specific questions and seeing what others are running. Watch out: buying advice skews toward more expensive/enterprise gear than a beginner needs. Status: active, large, free.
• r/selfhosted -- Reddit, software-focused: what to run, comparisons, troubleshooting. Best for: "what should I use for X" questions. Watch out: recommendations can be trend-driven (whatever's popular that month) rather than always the best long-term fit. Status: active, large, free.
• lemmy.world/c/selfhosted and lemmy.world/c/homelab -- the fediverse (Lemmy) equivalents of the two subreddits above, on one of the largest Lemmy instances. Best for: the same kind of discussion, for anyone who prefers a non-corporate, federated platform. Watch out: smaller and slower-moving than the Reddit equivalents -- fewer responses, longer to get an answer. Status: active, smaller community, free.
• Individual project Discord/Matrix servers -- most self-hosted projects of any real size have their own, usually linked from the project's own README or website. Best for: project-specific troubleshooting from people who actually maintain or deeply know that project. Watch out: quality and responsiveness vary a lot by project size. Status: varies per project -- check the specific project's own links.
• Proxmox VE Community Forum -- Proxmox's own official forum. Best for: Proxmox-specific issues, more authoritative than general communities for that specific software. Watch out: narrower scope than the general communities above. Status: active, official, free.

Reference lists and discovery

• Awesome-Selfhosted -- a large, categorized list of self-hostable software alternatives to common cloud services. Best for: "there has to be a self-hosted version of this" starting points. Watch out: a list this large includes both actively maintained and effectively abandoned projects side by side -- check a specific entry's own repository activity before committing, the list itself doesn't filter for that. Status: actively maintained (320k+ GitHub stars, regular commits as of this check), free, open license.
• Awesome-Sysadmin -- the sysadmin-tooling equivalent: monitoring, backup, configuration management, and more. Best for: infrastructure/ops tooling discovery specifically, less consumer-app-focused than Awesome-Selfhosted. Watch out: same caveat as above -- a list, not a filter for current quality. Status: actively maintained, free, open license.
• r/selfhosted's own wiki and periodic "alternatives" megathreads -- community-sourced, opinionated comparisons a static list can't capture. Best for: real opinions and trade-offs, not just a name and a link. Watch out: opinions, not authoritative -- cross-check anything load-bearing. Status: community-maintained, free.

Learning resources

• CompTIA Network+ and Security+ -- widely recognized entry-level certifications covering networking fundamentals and security fundamentals respectively. Best for: structured, employer-recognized validation if you're learning for career reasons, not just homelab curiosity. Watch out: certification content moves slower than the actual industry -- useful for fundamentals, not for staying current on specific tools. Status: paid (exam fees), vendor-neutral, widely recognized.
• TechnoTim, NetworkChuck, Lawrence Systems, Craft Computing, LearnLinuxTV (YouTube) -- creators covering, respectively: Kubernetes/homelab automation, networking fundamentals explained accessibly, enterprise-adjacent firewall/network deep dives, hardware-focused builds, and Linux/self-hosting tutorials. Best for: video-format learning and seeing real hardware/setups, not just text instructions. Watch out: as with any single creator, cross-check anything security- or data-loss-sensitive against the software's own official documentation before acting on it -- this is general practical advice, not a claim about any specific creator's accuracy. Status: free, ad/sponsor-supported, active as of this check.
• The official documentation for anything you're actually running -- worth stating plainly: for any tool covered by a DaemonPress Build guide, that guide's own Resources section links the official docs directly. Bookmark those over third-party tutorials once you're past the initial setup.

Hardware sourcing

• Buying used enterprise gear -- a common, often cheaper path to homelab hardware than consumer new. What to look for: ECC RAM support if you want it, IPMI/iDRAC/iLO for remote management (a real convenience once you stop keeping a monitor next to the box), and rack rails/depth if you're going that route. What to watch out for: enterprise gear is often loud (server fans are tuned for a data center, not a bedroom closet) and power-hungry compared to consumer mini PCs -- check idle power draw specifically before buying, not just performance specs. Communities above (particularly r/homelab) are a good source of model-specific advice on noise and power before you buy.

Comparison tables

Wherever two or more tools in this space do essentially the same job, a straight description of each doesn't help you choose -- here's the trade-off directly.

Reverse proxies

A full Comparison and a Build guide using Caddy specifically both exist in this section for a deeper look than the summary below.

DNS-level filtering

Hypervisors and virtualization platforms

Backup tools

Monitoring and observability stacks

Verify it works

This is a reference page, not a build -- there's nothing to verify in the usual sense. If you want a self-check: you should be able to name at least one entry from three different sections above that's relevant to something you're actually doing, and you should understand why each comparison table's entries aren't interchangeable (what specifically would make you pick one over another).

Changelog

• 2026-09-21 -- Full rewrite: retyped from Build to Reference (the original had a fake "0/5 steps" progress meter, a Verify it works checklist that couldn't fail, and a Troubleshooting section that said there was nothing to troubleshoot -- exactly backwards for a links page). Added explicit selection criteria and four start-here paths. Expanded coverage from Reddit-only communities to include Lemmy/fediverse and project-specific Discord/Matrix. Added Learning resources (certifications, creators) and Hardware sourcing sections, both entirely absent from the original. Added five comparison tables (reverse proxies, DNS filters, hypervisors, backup tools, monitoring stacks) with real entries, each carrying a best-for/watch-out/status per the standard's requirement -- the original named three reverse proxies with no comparison at all. Every entry now states a working link, one-line description, best-for, watch-out, and status/license explicitly -- the original's entries were one line each with none of that. Corrected tags: dropped Backup & recovery and Linux, neither of which the original page actually taught in substance (it linked to things, it didn't teach them) -- kept self-hosting and open-source, which the page's actual content does substantively cover. Moved from it-sysadmin to sysadmin-fundamentals.
• 2026-09-21 (earlier) -- Original version published as a Build-type page with no actual build.
