Adminer review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Adminer is a web-based database administration interface distributed as a single PHP file. It is designed for developers and database administrators who need a compact browser-based way to connect to database servers, create or select databases, inspect schemas, edit records, run SQL, manage permissions and export data. The core distribution supports MySQL, MariaDB, PostgreSQL, CockroachDB, SQLite, Microsoft SQL Server and Oracle, while plugins add engines including Elasticsearch, SimpleDB, MongoDB, Redis, Firebird and ClickHouse.

Its main strength is the breadth of routine administration available from one interface. Users can inspect and modify tables, columns, indexes, foreign keys and triggers; browse, search, sort and aggregate table data; and insert, update or delete records. Adminer also handles views, stored procedures, functions, triggers, users and permissions, with SQL and CSV export for database structures and data. Query history is included, and SQL can be entered in a text field or loaded from a file. This makes it a practical fit for straightforward administration and data maintenance across varied database environments.

Adminer is distributed free as open-source software under the Apache License or GPL, with PHP and sessions required for operation. Its single-file deployment keeps the product focused, but the stated feature set does not include visual query building or SSH tunneling. Choose Adminer when browser access, low-cost deployment, direct SQL work and core database administration are the priority. Teams that need a visual query design workflow or SSH-based connection features should choose a database client built around those capabilities instead.
