Overview
Adminer is a lightweight database administration tool packaged as a single PHP file. It supports MySQL, MariaDB, PostgreSQL, SQLite, MS SQL, Oracle, Elasticsearch, and MongoDB through a pluggable driver system. It provides table browsing, query execution, import/export, and schema editing. Deployment is as simple as copying one file to a PHP-enabled server or pulling the official Docker image.
Where it falls short of Retool
- No built-in access control beyond HTTP auth; unsuitable as a team-facing data portal
- No chart or dashboard visualisation; purely a raw data management tool
- No audit logging or change approval workflows
- UI is functional but dated compared to modern alternatives
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
