SaaS Glossary

Here you can find important tech terms and definitions, explained in a simple and clear way.

Native App

A Native App is a software application built using the specific programming languages and tools dedicated to a single platform or operating system (such as Swift or Objective-C for Apple iOS, and Kotlin or Java for Android). Because they are written specifically for that ecosystem, native apps are installed directly onto the device (via the App Store or Google Play) rather than being accessed through a web browser.

Net Promoter Score (NPS)

Net Promoter Score (NPS) is a widely used market research metric that measures customer loyalty and satisfaction. It is calculated by asking users a single, standard question: "On a scale of 0 to 10, how likely are you to recommend our product/company to a friend or colleague?" Respondents are categorized as Promoters (9-10), Passives (7-8), or Detractors (0-6). The final score ranges from -100 to +100.

GUI (Graphical User Interface)

A GUI (Graphical User Interface) is a visual way for users to interact with computers, software, and websites. Instead of typing complex, text-based commands into a terminal, users interact with a GUI using visual indicators like windows, icons, menus, buttons, and a pointing device (like a mouse or a touchscreen).

Xano

Xano is a highly advanced, scalable, "No-Code" backend development platform. It provides developers with a powerful PostgreSQL database, a flexible API builder, and a server environment without requiring them to write backend code. It is designed to pair perfectly with frontend builders like Webflow (often connected via Wized) to create robust, full-stack Web Applications.

Wized

Wized is an advanced low-code platform that acts as a logic and authentication layer for Webflow. It allows developers to transform a static Webflow marketing site into a fully functional, data-driven Web Application. By connecting Webflow's frontend directly to external databases (like Xano, Supabase, or Airtable) and REST APIs, Wized enables user login portals, gated dashboards, and complex data manipulation.

Web Application (Web App)

A Web Application (Web App) is a piece of interactive software accessed through a web browser. Unlike a traditional "website" (which is primarily designed to display static information or marketing content), a web application is highly interactive, allowing users to manipulate data, create profiles, conduct secure transactions, and utilize complex tools (e.g., Salesforce, Google Docs, or a proprietary SaaS dashboard).

Churn Rate

Churn Rate is a critical business metric that calculates the percentage of customers or subscribers who cancel or fail to renew their subscriptions during a given time period. In the SaaS industry, it is the inverse of the Retention Rate and is a primary indicator of product health, customer satisfaction, and long-term revenue viability.

Authentication

Authentication is the critical security process of verifying the identity of a user, device, or system before granting access to protected resources, dashboards, or gated content. In the context of web applications and SaaS platforms, it is the mechanism that ensures the person attempting to log in is actually who they claim to be, typically utilizing credentials like passwords, biometric data, or security tokens.
