Fair Screen
Create session
We mint a signed pair: Dashboard + Agent.
Expose the invisible overlay layers.
Not a background process killer. Fair Screen is a privacy-first integrity layer for remote tech interviews that quietly detects invisible overlay windows, ghost coder tools, and remote control sessions even when screen sharing is blocked. It never records or keylogs, just emits harmless risk signals. It also flags when a virtual machine or Remote Desktop is in use by checking for their harmless "footprints," not your content.
Detects invisible windows from popular tools
How it works
Share Agent
Share this link with the interviewee. The Agent just sends small status updates.
Monitor events
See live warnings if any hidden or unusual windows appear on the candidate’s screen.

We’ve got you covered
What is Fair Screen even about?
+
Fair Screen is a privacy-first integrity layer for remote tech interviews.
It quietly detects suspicious overlays, ghost coder tools, and remote control signals
on the candidate's device and sends a simple risk signal to the interviewer without
screen recording, keylogging, or creepy surveillance.
When is the macOS version coming?
+
We’re prioritizing Windows first. A macOS Agent is on our roadmap and will land sooner if we secure funding or see strong user demand.
If response is great or if we’re funded we’ll accelerate macOS support.
How is Fair Screen different from LockDown Browser?
+
LockDown Browser completely locks down the candidate’s computer. It force-closes apps, blocks shortcuts, prevents
tab switching, and often records screen or webcam activity.
Fair Screen does none of that. It does not lock the machine, monitor the candidate, or restrict what they can open.
Instead, Fair Screen quietly detects invisible overlays, remote desktop sessions, and virtual machine footprints using harmless OS-level signals — no surveillance, no screen recording, no forced lockdown.

How is Fair Screen different from HackerRank or CoderPad’s built-in detections?
+
HackerRank, CoderPad, and similar platforms only detect activity inside their own editor — tab switches,
paste attempts, browser focus changes, or code similarity.
Fair Screen works outside the browser entirely. It detects hidden overlay tools, ghost-coder windows, remote desktops, and virtual machine usage — things a website cannot see.
This means the interviewer gets signal even if the candidate uses a different window, a desktop tool, or another device to cheat — things platform-based detections miss completely.

Are there limits on the number of sessions?
+
For now, sessions are unlimited. In the future, session limits will apply based on your subscription plan.
How is this different from process killing tools?
+
Fair Screen doesn’t scan or kill processes. It quietly detects hidden overlays by watching how windows appear, stack, and behave without recording or invading privacy.
Does it work if the candidate shares a single window?
+
Yes. The Agent runs locally and streams only event signals to your Dashboard.
Will Fair Screen detect if the candidate is on a Remote Desktop (RDP) session?
+
Yes. The Agent signals when the current Windows session is remoted in via RDP. You’ll see an “RDP” badge and an event in the stream.
Can Fair Screen tell if the candidate’s machine itself is a virtual machine?
+
Usually, yes. When present, the “VM” badge lights up and an event is logged.
Will it detect a VM running elsewhere on the host if the Agent is inside a guest VM?
+
No. Software inside a guest VM can’t see the host’s other apps. The Agent reports what’s observable inside the OS it’s running on.
Can Fair Screen tell if the candidate remotes from one VM into another VM?
+
Yes, if the Agent runs in the active desktop where the remote session is open. The RDP/remote indicators will still trigger in that environment.
Does it work if the candidate shares only a single window?
+
Yes. Sharing mode doesn’t matter. The Agent runs locally and streams only lightweight event signals to your Dashboard.
Will Fair Screen record the candidate’s screen or keystrokes?
+
No. Fair Screen never records the screen, audio, camera, or keys. It only reports privacy-safe signals (e.g., presence of invisible overlays, remote/VM indicators).
What happens if the candidate closes the remote tool mid-interview?
+
The “Remote/VM Client Activity” table updates to show that the process ended, and a “closed” event appears in the stream. The row is removed once the process fully exits.
