Adminer vs DbNinja

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.

DbNinja is a web application for administering and developing MySQL databases, including databases on remote hosted servers. It can manage database objects such as tables, events, indexes, triggers, procedures, views, users, and privileges. For maintenance, it backs up and restores database structure and data, and compares or synchronizes databases between hosts. Exports are available in CSV, SQL, Excel, and JSON formats. Query tools include syntax highlighting, saved favorite queries, and limits on fetched data and query execution time. You can connect to multiple hosts at once and work in tabs.

DbNinja is self-hosted: setup involves copying its package into a directory in your webroot and completing setup in a browser. It requires a PHP-enabled web server, PHP 5.3 or higher with mysqli, MySQL 4.1 or higher, and a recent major browser with cookies enabled. The Personal use plan is free and is for user-installed use from one computer at a time. Commercial licensing is available by quote.
