LockDown Browser vs Honorlock vs Proctorio: 2026 Comparison
TL;DR
All three tools read from the same OS screen-capture API. None of them can see a system-overlay AI tool like Lockdownify. The differences between them matter for the proctor's experience, not for what a student needs to bypass them.
Students often assume each proctoring platform is technically different in fundamental ways. They aren't. All three use roughly the same monitoring layers; they differ mostly in how they package the experience for the proctor.
LockDown Browser (Respondus)
Browser-replacement model. The student installs a custom browser that takes over the machine for the duration of the exam. Aggressive process scanning. Strict on VMs and second monitors.
Fails against system-overlay AI tools because it reads from the same OS API as everyone else.
Honorlock
Browser-extension model + live proctors. Less invasive at install, more invasive during. The honeypot search results are unique to this stack.
Fails against system-overlay AI tools because the live proctor sees the same recording the AI sees.
Proctorio
Browser-extension model. The most aggressive behavioral-analytics layer of the three. Suspicion scores trip on small head movements and gaze changes.
Fails against system-overlay AI tools, and the gaze model doesn't trip when the overlay is positioned near the question text.
What this means in practice
If you've been told one of these is uniquely impossible to bypass, that's marketing more than engineering. They share the same underlying capture mechanism, and they share the same blind spot — anything excluded from the OS screen-capture API never enters their data stream.

Which one is the hardest to bypass?
From a pure detection standpoint, Proctorio's behavioral analytics are the most sensitive. From a capture standpoint, all three are equivalent — they all read from the same OS API and miss the same system-overlay layer.
Can the same tool work on all three?
Yes. Lockdownify is invisible to LockDown Browser, Honorlock, and Proctorio simultaneously because the exclusion is at the OS level, not at the proctoring-vendor level.
Will Lockdownify get me caught?
No. Lockdownify is filtered out of every screen-capture pipeline at the operating-system level — before a single pixel is ever encoded. LockDown Browser, Honorlock, Proctorio, Zoom, Teams, and Meet all read the same OS frame buffer, and Lockdownify is excluded from it. We re-test against every major proctoring tool weekly. If you ever do get flagged, we refund your subscription and reimburse the exam fee.
What platforms does Lockdownify support?
macOS 13 Ventura and later, and Windows 10 and 11. Both desktop apps ship today.
How much does it cost?
$40/month or $28/month if you pay annually (save 30%). One plan unlocks every model — Claude Opus 4.7, GPT-5, and Gemini 3.1 Pro — unlimited questions, unlimited screenshots, and the 100% bypass guarantee. Cancel anytime.
