Constructor Proctor leads on live contact, hosting, languages, and phone and tablet exams. Proctors call candidates by audio or video and watch webcam, screen, and phone camera on one video wall, while Respondus Instructor Live Proctoring runs through a separate video conferencing system and does not record or flag. Constructor Proctor runs in Constructor Cloud or on-premise on your own servers, where Respondus describes cloud hosting on AWS with servers in the United States. It shows the candidate interface in 40 languages and the proctor console in 38, against six interface languages for Respondus, and it supports exams on iOS and Android phones and tablets, where Respondus says LockDown Browser and Monitor are not available on phones.
Respondus does some things better. LockDown Browser is a native app for Windows, Mac, Chromebook, and iPad that blocks virtual machines, remote desktops, and hundreds of screen capture and screen-sharing apps, and Respondus offers ready integrations with Canvas, Blackboard, Moodle, Brightspace, Sakai, and Schoology. Monitor needs no booking, flags handheld devices, and ranks sessions by review priority, with results reaching instructors in about 10 to 15 minutes. Respondus also covers classroom and testing-center exams with an exam password, offers 24/7 live chat for students and free instructor training, and states SOC 2 compliance.
Both products offer automated and record-and-review proctoring with AI flags, live proctoring, a second camera by QR code, device lockdown, and integrations with the major LMSs. The choice comes down to whether you want your own staff or trained partner proctors, phone and tablet exams, and control over hosting and languages, or a browser and webcam tool that instructors run themselves inside the LMS they already use.
