VerdictDependsDepends
Best forJava development teamsSelf-hosters replacing MS Access
Who it's not forNon-Java stacks (PHP, .NET, Python, JS)Non-technical teams wanting hosted plug-and-play
PrivacyNo known public vulnerabilities found in the sources reviewed.²Two 2010 CVEs on record (XSS, directory traversal) plus a file-inclusion exploit; vendor publishes no security page.14
Support qualityNo support evidence in sourcesCommunity forums and GitHub only; no vendor SLA
Public sentimentUser feedback is scarce: only two verified G2 reviews average 4.5 stars, and no verbatim quotes appear in the reviewed sources.⁵Users praise it as a free, lightweight MS Access replacement, but discussion centers on self-installation effort and required PHP skills.10
Biggest gotchaGuess: advanced features likely sit in paid commercial editions; verify licensing before building on the free core.²You host it: server maintenance, backups, and security patching are entirely your job
