Adminer (formerly "phpMinAdmin") is an alternative DB management tool to phpMyAdmin. Created by Jakub Vrána in 2007. The key difference — Adminer is a single PHP file (about 500 KB), so installation is very easy. phpMyAdmin spans many files and directories (about 20-30 MB).
Adminer's advantages
First advantage — lightness. A full DB management interface in one PHP file. Installation: upload the file to public_html and open in a browser. No configuration, dependencies, or composer required.
Second advantage — multi-DB support. Adminer supports MySQL, MariaDB, PostgreSQL, SQLite, Microsoft SQL Server, Oracle, Elastic, ClickHouse, and others. phpMyAdmin is mainly tuned for MySQL/MariaDB.
Third advantage — clean interface. Adminer is built minimally — needed functions are immediately visible, no clutter. Good for newcomers.
Fourth advantage — security. Because Adminer is small, it's easier to audit and fewer vulnerabilities are found. phpMyAdmin has many historical CVEs.
Differences from phpMyAdmin
Functionally they can do the same things: create tables, view data, write SQL queries, import/export. But Adminer has fewer advanced features — no designer (ER diagram), no tracking, less key management.
Performance: Adminer is faster than phpMyAdmin — page loads and query results appear sooner.
Browser memory: viewing a large DB in phpMyAdmin can crash the browser; Adminer uses less RAM.
Installation and use
1) Download the latest version from adminer.org (about 500 KB PHP file). 2) Upload to public_html (for security, rename it, e.g., db-mgr.php). 3) Open http://yoursite.uz/db-mgr.php in a browser. 4) Log in with: server (localhost), username, password, database (optional).
Security tips
Adminer requires the same security care as phpMyAdmin. (1) Rename from the default; (2) IP whitelist via .htaccess; (3) Delete the file after use (it doesn't need to live permanently in production); (4) Access over HTTPS.
Sayt.uz practice
Among Sayt.uz clients 8% use Adminer (phpMyAdmin 84%) — mostly developers and DBA-savvy clients. Adminer isn't default on hosting, but clients can download and run it themselves. Tip: if you're a normal WordPress client, stay with phpMyAdmin. If you're a developer using custom PostgreSQL or SQLite, Adminer is a good choice.
