Broad database support, including through plugins
Actively maintained with regular releases

Requires a PHP server environment to run
Less feature-rich UI than dedicated desktop database clients
Care is needed when exposing it on a public-facing server, as with any web-based DB admin tool
ChartDB
Pros
Completely free and open-source with no installation required for basic use
Strong privacy model since database credentials never leave the user's machine
Fast single-query schema import and instant diagram rendering
AI-assisted diagram generation and cross-dialect SQL export
Cons
Young project (launched 2024) with a very small core team
No confirmed enterprise support tier or SLA
Primarily community-supported rather than backed by dedicated customer success
Advanced collaboration and version history features may be less mature than long-established paid tools
