Cross-device uploads with a developer-first experience

SyncSnap helps users move from desktop to mobile capture in seconds. You ship a polished upload flow with fewer edge cases and no separate mobile app—one SDK, one API, and no account or app install required on the user’s phone.

Quickstart

Integrate in minutes — two files, a few lines each

Next.js App Router

Step-by-step integration for Next.js

​
How it works

  1. Embed once — Add the SyncSnap SDK and render one component where uploads begin.
  2. Capture anywhere — The user scans a QR code and switches to their phone for camera-friendly uploads.
  3. Continue your flow — Files stream back to your app and the wait endpoint returns the result (e.g. presigned download URL or custom payload).
No mobile app, no sign-in on the phone—just scan and upload.

​
What you need

  • A SyncSnap project and API key from the dashboard.
  • Backend — the syncsnap server SDK to create jobs and proxy job/download requests.
  • Frontend — the @syncsnap/react package for the upload button, QR code, and job polling.

​
Frameworks

SyncSnap provides a first-party integration for Next.js (App Router). The server SDK is Node-friendly and can be used with other frameworks by implementing the same API routes.
