What Are the Main Features of Kexi?

Updated

Kexi is a free, open-source visual database application builder from the KDE community, distributed at kexi-project.org. Its main purpose is to let you create and manage databases and data-driven forms through a graphical interface rather than by writing an application from scratch. It fits people who want a desktop database tool with a visual designer — for example, building a small inventory, contact, or membership database — and who are comfortable installing KDE-ecosystem software. If you need a purely web-based database or a large multi-user server platform, Kexi is not aimed at that use case.

Core feature areas

Kexi combines several tools that normally appear in separate products: a data table editor, a query builder, a form designer, a report generator, and a scripting layer. The table below summarizes what each area does.

Feature area What it provides Typical use
Table designer Create and alter tables, set field types, keys, and constraints Defining the structure of your data
Data view Enter, browse, and edit records in a grid Day-to-day data entry and review
Query designer Build queries visually, including joins and calculated fields Filtering and combining data without SQL
Form designer Drag-and-drop widgets bound to table or query fields Data-entry screens for non-technical users
Report designer Lay out printable reports from tables or queries Printed lists, summaries, labels
Scripting / macros Automate actions and extend forms Repeating tasks, custom behavior

Data management and application development

Kexi is both a data manager and a lightweight application builder. You can:

  • Work with multiple database backends. Kexi can use its own file-based format and can also connect to server databases, so the same project style can scale from a single file to a shared server.
  • Bind forms to queries, not just tables. This lets a form show filtered or joined results rather than raw rows.
  • Reuse queries inside forms and reports. A query defined once can feed several forms and reports, which keeps logic in one place.
  • Add interactivity through scripting. Form widgets can trigger scripts, so a form can do more than display and save records.

The practical result is that a non-programmer can assemble a working data application — structure, entry screens, and printed output — inside one tool.

Where Kexi fits best

Kexi is a good match when:

  • You want a desktop database front end with visual design tools.
  • Your project is small to medium in scope, such as personal, departmental, or small-business data.
  • You prefer an open-source, KDE-based tool and are willing to install it through your distribution or the project's downloads.
  • You need forms and reports as much as raw tables.

It is a weaker match when you need a browser-only interface, a hosted cloud service, or very large concurrent multi-user workloads.

Limitations and things to check

  • Platform and installation. Kexi is part of the KDE application family, so availability and packaging vary by operating system. Check the project site for the current download and platform options before committing.
  • Learning curve for advanced features. Basic tables are quick, but queries, scripting, and report layout take practice.
  • Backend differences. Behavior and available features can differ depending on which database backend you connect to, so confirm that your intended backend supports what you need.
  • Documentation currency. Because it is a community project, some guides may lag behind the current release; verify details against the version you install.

A sensible first step is to install Kexi, create a small test table, and build one form and one report. That exercise will show you quickly whether its feature set matches your project before you invest time in a full database.
