Digital marketing term
Open Source
Software whose source you can inspect, use, and change under a published license. It is not required to be free of charge; the point is that the code is not a locked box.
Detailed explanation
WordPress and many analytics and front-end libraries sit here. MIT, Apache, and GPL licenses differ on attribution, sharing derivatives, and commercial use.
Do not equate it with free: plugins, hosting, and security patches still cost work. Embedding code without reading the license is a legal risk. Tying production to an abandoned repo is silent debt.
Choose on license, release cadence, security notices, and whether you can patch. Closed SaaS sells support; open source sells inspectability and less lock-in—different commercial bets.
Frequently asked questions
- Is open source always free?
- Visible code often comes with a free license, but support, hosting, and commercial plugins are paid. The license text is what binds you.
- What does a marketing site gain?
- Transparency in the CMS and tags, a plugin ecosystem, and less vendor lock-in. You own the update discipline in return.

- CMSSoftware that separates content from code so editors can ship pages, images, and URLs as HTML. You should not need an FTP login for every glossary update.
- HTMLThe markup a browser uses to build a page’s structure: headings, paragraphs, links, and forms. CSS paints it and JavaScript makes it interactive; markup itself is not a programming language.
- JavaScriptThe language that makes pages interactive in the browser: menus, form checks, tag managers, and most modern UI. HTML structures the page, CSS styles it, and this layer handles behavior.
- CSSThe stylesheet language that sets color, type, space, and layout on an HTML page. It decides how the interface looks and how interactions feel in the browser.
- HostingThe service that keeps a site’s files, database, and mail on a machine reachable from the internet. A domain does nothing until DNS points it at that server.
- DatabaseThe structured store for records: users, orders, content, and subscriptions. In marketing, “the list” is usually a view of this store, not a spreadsheet.
