Our verdict on KoolReport QueryBuilder
KoolReport QueryBuilder is a free, open-source PHP package for constructing SQL through a fluent API. It is aimed at PHP developers who want to generate queries in code, including parameterized SQL and its associated parameters for use with untrusted input. Documented operations cover selects, filters, joins, unions, subqueries, aggregates, inserts, updates, deletes, and truncation. The package is presented for KoolReport use, and its repository also documents standalone query-to-SQL methods, so it can suit developers looking for query construction rather than a broader database platform.
Its strongest fit is breadth within query generation: the API covers common read and write operations, aggregate functions such as count, max, min, average, and sum, and raw expressions in select, where, having, and order-by clauses. It can compile MySQL, PostgreSQL, and SQL Server query formats, retrieve generated parameters, and restrict generated queries with configured schemas. That gives PHP teams flexibility across several SQL dialects while retaining parameter handling. At the same time, raw expressions are an escape hatch rather than a typed interface, and the documented dialect range is narrower than a tool supporting a broader database ecosystem.
The repository describes QueryBuilder as free, and Composer is the documented installation route; the published material does not present separate paid tiers. It is self-hosted, with community and email support channels, making it a reasonable fit for solo and small teams as well as mid-market PHP projects that can manage their own integration. Choose it when fluent PHP construction, parameter retrieval, and its supported query operations match the project. Look elsewhere if the application needs broader dialect coverage or a database workflow beyond query generation.
