BROWSER-BASED EMDR · 11
EMDR that opens in a browser tab.
Everything a therapist needs to run bilateral stimulation remotely, without a single download for the client.
DEFINITION
Browser-based EMDR is online EMDR delivered through a standard web browser: the therapist and client each open a URL, and bilateral stimulation renders directly in the page. There is no application to install and no account for the client to create.
What is browser-based EMDR?
It is the delivery model where bilateral stimulation runs inside the browser's rendering engine and audio subsystem, rather than a native desktop or mobile application. The therapist keeps a full control panel; the client sees only the moving target.
How is it different from a downloaded app?
There is no installer, no forced update, no operating-system version conflict and no third-party account for the client. Sessions start from a link — the same delivery model as a modern video call.
Why clinicians choose browser-based delivery
Reduced friction supports the therapeutic frame. Clients who are already stressed do not need to troubleshoot a new application at the start of a session. Universal browser support also simplifies clinic IT and cross-border work.
How BilateralSync implements it
BilateralSync renders BLS on an HTML canvas at the device's native refresh rate, generates stereo audio through the Web Audio API, and synchronises therapist controls to the client screen with sub-100 ms latency. No client account is needed and no client PII is collected.
Frequently asked questions
What is browser-based EMDR?＋
Browser-based EMDR is a form of online EMDR in which bilateral stimulation is delivered through a standard web browser instead of a downloaded desktop or mobile application. The therapist and client each open a URL; nothing else is installed.
Why does browser-based delivery matter clinically?＋
It removes friction that competes with therapy: no installer, no update prompts, no cross-platform incompatibility, and no account for the client to create. Clients arrive at a link and see the moving target immediately, which supports the therapeutic frame.
Is browser-based EMDR secure?＋
A well-designed browser-based tool encrypts traffic in transit, uses unguessable short-lived session codes, and does not collect client PII. BilateralSync is built with these defaults on.
Does browser-based EMDR work on phones and tablets?＋
Yes. Modern browsers on iOS, iPadOS, Android, macOS, Windows and Linux render the same client view. BilateralSync supports desktop, tablet and mobile for both therapist and client.
Does browser-based EMDR support auditory bilateral stimulation?＋
Yes. Stereo audio is rendered by the Web Audio API directly in the browser, so left-right panned tones stay in perfect sync with the visual target.
