SaaS, Software as a Service, is a software delivery model where an application is hosted centrally in the cloud and accessed through a browser, typically via a recurring subscription — rather than being purchased outright and installed on a local device.
Examples of SaaS Products
- Google Workspace and Microsoft 365 — cloud-based productivity suites
- Shopify — a fully hosted eCommerce platform
- Mailchimp — cloud-based email marketing software
- Slack — a hosted team communication tool
Why SaaS Has Become So Dominant
- No installation or complex local setup required
- Automatic updates handled entirely by the provider
- Accessible from any device with a browser and an internet connection
- Predictable, typically manageable subscription-based pricing
WordPress vs. SaaS Website Builders
WordPress.org itself is self-hosted, open-source software, distinct from SaaS platforms like Wix or Squarespace, which are fully hosted, all-in-one services. WordPress.com, notably, offers a SaaS-style hosted version of the same underlying WordPress software, sitting somewhere between the two models.
