About Reel Tester PRO

Welcome to Reel Tester PRO. We are a dedicated team of engineers and motion designers who were tired of exporting videos, sending them to our phones, uploading them to private Instagram accounts, and realizing our captions were blocked by the Like button.

We built this tool to solve a single problem: Verifying vertical video safe zones instantly.

Our Architecture

Unlike other video tools that require you to upload your unreleased content to their cloud servers, ReelTester operates on a strict Data Sovereignty Pipeline.

When you load a video into our simulator, 100% of the media rendering happens entirely inside your local browser memory (RAM). Your files never leave your device. We believe your unreleased content belongs to you.

The Modern Creator's Workflow

Whether you are trying to view Instagram Reels overlays, check the TikTok interactive dead zones, or figure out where to place YouTube Shorts graphics, our platform standardizes the process.
