Scan Instant - Open MRI & CT scans instantly - no install, on any device.

Got MRI/CT files your doctor can't open? Scan Instant fixes that. Drop any DICOM or NIfTI file — no install, no signup, no server. Everything runs in your browser. Works on your phone. Built for doctors who can't access patient scans on the spot, and patients who want to access their own imaging. Features: zoom, pan, side-by-side compare, clinical presets (Brain/Bone/Lung), measurement ruler, ROI, multi-planar views, CINE playback, ZIP batch upload, and export to PNG. Your scans. Open. Now.

I built Scan Instant because of a personal frustration. I needed ongoing MRI reviews and every time I went to a radiologist or orthopedic doctor for a second opinion, they'd say "we don't have the software to open this". So I went from zero coding knowledge to building a browser-based MRI viewer in under two weeks using vibe coding. No install. No account. Just drag your DICOM or NIfTI files and they open, on your phone, on any computer. It already handles things some dedicated apps don't — like DICOM files without extensions, ZIP batch uploads of full study folders, and a side-by-side compare mode with a difference heatmap. Primary users: doctors who need to open scans quickly without proprietary software. Secondary: patients who want to see and understand their own imaging before or after appointments. Would love your feedback — especially from anyone in healthcare. What would make this actually useful in a clinical setting?
