Billions and billions of copies +of SQLite exist in the wild. SQLite is found in: + +<ul> +<li>Every Android device +<li>Every iPhone and iOS device +<li>Every Mac +<li>Every Windows10 machine +<li>Every Firefox, Chrome, and Safari web browser +<li>Every instance of Skype +<li>Every instance of iTunes +<li>Every Dropbox client +<li>Every TurboTax and QuickBooks +<li>PHP and Python +<li>Most television sets and set-top cable boxes +<li>Most automotive multimedia systems +<li>Countless millions of other applications +</ul> + +<p>Since SQLite is used extensively in every smartphone, and there are +more than 4.0 billion (4.0e9) smartphones in active use, each holding +hundreds of +SQLite database files, it is seems likely that there are over one trillion +(1e12) SQLite databases in active use. + +<h2>Most Widely Deployed Software Module of Any Type?</h2> + +<p>SQLite is probably one of the top five most deployed +software modules of any description. +Other libraries with similar reach include: + +<ul> +<li> +The original <a href="http://zlib.net">zlib</a> implementation by +Jean-loup Gailly and Mark Adler. +<li> +The original reference implementation for +<a href="http://www.libpng.org">libpng</a> +<li> +Libjpeg from the <a href="http://ijg.org">Independent JPEG Group</a> +</ul> + +<p> +Libc is omitted from the above list even though +it is more common than SQLite because +libc is not a single software component but rather several +competing implementations (ex: BSD vs. GNU) with similar interfaces. +There are also independent implementations of libjpeg and libpng, +though in those cases the canonical implementations are very popular. +</p> + +<p> +Precise numbers are difficult to obtain and so exact rankings +are impossible. But our best guess is that SQLite is the second +mostly widely deployed software library, after libz. +Some commentators observe that SQLite tends +to be statically linked and thus have multiple instances on +each machine, whereas libz tends to have just +a single instance per machine in the form of a shared library or DLL. +So even though the number of devices containing libz +may be greater than the number of +devices that contain SQLite, the total number of instances per device +<em>might</em> be higher for SQLite and so SQLite <em>might</em> +be the single most widely deployed and used software component. +</p> +<p align="center"><small><i>This page last modified on <a href="https://sqlite.org/docsrc/honeypot" id="mtimelink" data-href="https://sqlite.org/docsrc/finfo/pages/mostdeployed.in?m=e39f595cab">2022-01-08 05:02:57</a> UTC </small></i></p> + |
