Adminer vs pgAdmin

Adminer is web-based database management software distributed as a single PHP file. It supports MySQL, MariaDB, PostgreSQL, CockroachDB, SQLite, MS SQL, and Oracle; plugin drivers add Elasticsearch, SimpleDB, MongoDB, Redis, Firebird, ClickHouse, IGDB, and IMAP. Users can create and alter database structures, including tables, columns, indexes, foreign keys, views, procedures, functions, and triggers. The interface can search, sort, and limit table results, edit records, run SQL, review query history, and export to SQL or CSV. Listed database capabilities include generated columns and check constraints, MySQL events and partitions, and PostgreSQL schemas, sequences, and user types. Adminer requires a database password and rate-limits connection attempts. Its site recommends restricting public access, for example with IP whitelisting or web-server password protection, and keeping the software updated. Plugins can add options such as OTP or passkey login, SSL connections, SQL highlighting, and extra export formats. It supports PHP 5.3+, 7, and 8 with sessions enabled. Adminer is free for commercial and non-commercial use under either the Apache License or GPL 2.

pgAdmin is a graphical tool for administering, developing with, and monitoring PostgreSQL databases. It runs as desktop software or in server mode, where multiple users can access it over the web. It supports PostgreSQL and EDB Postgres Advanced Server versions supported at the time each pgAdmin release is issued. Query tools include syntax highlighting, a data grid, graphical query plans, schema diff, an ERD tool, and a procedural language debugger. Users can manage common database objects and inspect their SQL definitions, properties, dependencies, and available statistics. Maintenance features include a monitoring dashboard, auto-vacuum management, and on-demand backup, restore, vacuum, and analyze operations. It also supports SSH tunneling, data editing, query history, and binary, CSV, or text result exports. The free plan costs nothing under the PostgreSQL Licence. Downloads include Windows and macOS installers, Linux packages, Docker, a Python wheel, and source code. Only the latest release is supported; there are no long-term stable versions.
