Privacy	No known public vulnerabilities found in the sources reviewed.^²	No known public vulnerabilities found in the sources reviewed.¹¹
Support quality	G2: very good docs and support	No support evidence reviewed
Public sentiment	A small but positive sample praising developer-friendliness, documentation, and support.^³	No user reviews surfaced in the sources reviewed; evidence is limited to the project's official pages.¹⁰
Biggest gotcha	Guess: lock-in . once SSO and directory sync run through WorkOS, ripping it out means rework^¹	Guess: 'Minimum effort' marketing hides realm, client, and role configuration work¹⁰
