'''Self-hosting''' is the practice of implementing digital services with server applications under one's own control. This is opposed to relying on large public services or [[Cloud (service)|cloud services]], compared to which it provides significantly more control over how the services are provided at the cost of responsibility for setting them up and keeping them operational over time.<ref name=":0">{{Cite web |title=About self-hosting |url=https://doc.yunohost.org/en/admin/about_self_hosting/ |url-status=live |archive-url=https://web.archive.org/web/20251217054550/https://doc.yunohost.org/en/admin/about_self_hosting/ |archive-date=2025-12-17 |access-date=2026-02-25 |website=Yunohost}}</ref> | |||

Self-hosting typically refers to usage of digital services '''hosted''' by a person for just themselves (hence the '''self-''' prefix), but they're often made available also to a circle of family and friends, especially services that feature collaboration. Before self-hosting rose to prominence similar installations were typically limited to organizations and housed internal tools, such as company chats and internal knowledge bases.{{Citation needed}} This is still common in organizations, only partially supplanted by [[Software as a service|software-as-a-service (SaaS)]]. | Self-hosting typically refers to usage of digital services '''hosted''' by a person for just themselves (hence the '''self-''' prefix), but they're often made available also to a circle of family and friends, especially services that feature collaboration.

Today, there are numerous free and open-source server applications available to everyone with an internet connection<ref>{{Cite web |title=Free software |url=https://awesome-selfhosted.net/ |website=Awesome-Selfhosted}}</ref>. Companies commonly employ dedicated system administrators to run such applications, due to some specialized knowledge required to set them up. But over the years the amount of knowledge required for this has been reducing, which has allowed more people to install such server applications by themselves.{{Citation needed}} | Today, there are numerous free and open-source server applications available to everyone with an internet connection<ref>{{Cite web |title=Free software |url=https://awesome-selfhosted.net/ |archive-url=https://web.archive.org/web/20260213070029/https://awesome-selfhosted.net/ |archive-date=13 Feb 2026 |website=Awesome-Selfhosted}}</ref>.

Most of the time, product manufacturers do not | Most of the time, product manufacturers do not allow users to specify their own servers for these services. In such cases manufacturers' infrastructure becomes integral to the product and often gives manufacturer complete access to the product post-purchase through software updates, allowing for a number of anti-consumer actions such as [[retroactively amended purchase]] (manufacturer changing the way the product functions) and [[discontinuation bricking]] (manufacturer shutting down their server, reducing functionality of the product or rendering it entirely inoperable). When using a self-hosted server these such actions can be prevented by cutting access to manufacturer's servers while preserving product functionality; however, most of the time it's not officially supported. | ||
This isn't limited to just physical products, it affects software as well. For instance, [[games as a service]] typically require a server to fully function, and server software for such games is not made available to users, making self-hosting for such games impossible and requiring manufacturer's active involvement in order to maintain full game functionality. There are, however, many multiplayer games, especially older ones, that do support self-hosting of servers through dedicated server software<ref>{{Cite web |title=Dedicated Servers List |url=https://developer.valvesoftware.com/wiki/Dedicated_Servers_List |access-date=2025-10-12 |website=Valve Developer Community}}</ref> | This isn't limited to just physical products, it affects software as well.

A lot of server software is capable of running on "normal" (consumer-grade) computers as well. So it is common to start self-hosting by installing server software on an unused computer that can be run continuously or whenever access to its services may be needed. | A lot of server software is capable of running on "normal" (consumer-grade) computers as well.

Software-wise, depending on requirements and the level of technical expertise, one might opt for a generic server OS such as [https://www.debian.org/ Debian], [https://ubuntu.com/server Ubuntu Server], and [https://www.freebsd.org/ FreeBSD] for a more do-it-yourself experience, or an OS purpose-built for self-hosting such as [https://yunohost.org/ YunoHost] or [https://umbrel.com/ UmbrelOS] which guides its users through some of the complexities of the process. In some more niche circumstances, [https://www.openbsd.org/ OpenBSD] might be preferred to other options as a server operating system due to its focus on security and simplicity. | |||
===Network-attached storage (NAS)=== | |||
Companies such as [[Synology]], [[QNap|QNAP]], [[UGreen|UGREEN]] and others offer commercial hardware products called NAS (Network Attached Storage) that expose disks to a network for shared access to files on them<ref>{{Cite web |last=Susnjara |first=Stephanie |last2=Smalley |first2=Ian |title=What is network attached storage (NAS)? |url=https://www.ibm.com/think/topics/network-attached-storage |url-status=live |archive-url=http://web.archive.org/web/20251114021534/https://www.ibm.com/think/topics/network-attached-storage |archive-date=14 Nov 2025|access-date=2025-11-22 |website=IBM |series=Think}}</ref> in form of a "network drive", "file share" or "shared folder". As an additional function, many such devices can also run server software, and may even offer user-friendly graphical interfaces for this out-of-the-box. | |||
Such devices are typically optimized for file management, and applications using the files stored by a NAS are expected to run on ''other'' devices on the same network (e. g. a PC running heavy video editing software utilizing video files stored on a NAS). As such, NAS devices, especially budget ones, often do not have much capacity for server applications. For a small number of users, however, as is common in self-hosting, they can be sufficient. | |||
A consumer NAS is typically more expensive than self-built solutions or second hand server-grade hardware, but due to better power management, the higher costs can be worth it in regions with high electricity prices. | |||

Counters consumer rights issues such as [[discontinuation bricking]], [[retroactive policy enforcement]] and [[post-purchase EULA modification]], mostly in regards to "connected" devices and smart homes. | |||
===[https://nextcloud.com/ Nextcloud]=== | |||
Provides remote file storage and sharing as a core function and numerous other functions available for easy installation: synchronization of contacts and calendars, a full-fledged browser-based editor for contacts and calendars, collaborative document editing, chat, video conferencing and more. Many of these are functions commonly seen as available only from large commercial providers, and Nextcloud serves as an example that disproves this notion. | |||
In addition to offering a comprehensive interface for the browser and a suite of first-party mobile apps, some third-party applications allow the use of Nextcloud for storing user data. Some such applications are: | |||
*[https://www.davx5.com/ DAVx⁵], a synchronization app for calendars, contacts and tasks on Android over the standard DAV protocols that Nextcloud implements | |||
*[https://www.onlyoffice.com/ OnlyOffice], an in-browser document editor within Nextcloud's interface and a desktop editor that connects to a Nextcloud account, both allowing access to files in Nextcloud and collaborative editing with other users | |||
*[https://floccus.org/ Floccus], a synchronization service for browser bookmarks and tabs, available across many browsers and as a mobile app, and synchronizing with a server chosen by the user, Nextcloud being only one of several supported options | |||
*[https://github.com/scubajeff/lespas Les Pas], a photo album Android app, automating photo uploads and browsing both local and remote photo albums | |||
*Apps that rely entirely on files for storage and can access Nextcloud through the operating system's interfaces and a Nextcloud client | |||
In numerous alternatives, particularly among mobile apps, similar functions are only provided by the app's developer or affiliated parties, and often for a fee, with no alternatives,{{Citation needed|reason=needs examples}} resulting in a [[vendor lock-in]]. | |||
===Network-wide ad blockers=== | |||
{{Main|Ad block}} | |||
Software suites that block access to advertising platforms to devices on the local network. | |||
While limited in what kinds of ads they are capable of blocking, they work where installing a more advanced ad blocker is more difficult or impossible, such as on devices with heavily locked down software or within individual applications. | |||
