New Server Side Licensing​

SciChart.js v5.2 introduces Simple Server Validation — a new Advanced Licensing option designed to make server-side license validation as painless as possible.

Unlike our existing Native Server (OEM) deployment, Simple Server Validation requires no native DLL, no FFI bridge, and no challenge/response handshake. Your server simply computes an HMAC-SHA256 token from a shared Server Secret and returns it to SciChart.js, which verifies it in WASM and caches the result for 7 days. That means a single endpoint, a few lines of code, and you're done.

Why you'll like it

  • Drop-in integration — typically under 20 lines of server code in any language that supports HMAC-SHA256.
  • No native dependencies — pure managed code on the server side; nothing to install, nothing to patch.
  • Works anywhere — Node.js, .NET (Minimal API and MVC), Spring Boot, Python, Go, Ruby, PHP, Rust.
  • Desktop apps too — Electron and Tauri can compute the token in the privileged process and pass it to the renderer over IPC, keeping the secret out of the bundle.
  • Low overhead — each browser only needs to hit your endpoint once per week, with automatic background re-validation every 24 hours.

Simple Server Validation is ideal for OEM scenarios where you need to deploy SciChart.js to unknown or user-controlled domains, or for desktop apps built on Electron or Tauri.

Get started

  1. Full documentation, including step-by-step implementation guides for every supported stack: Simple Server Validation — SciChart.js Docs
  2. Runnable example projects for Node.js, ASP.NET Core (Minimal API and MVC), Spring Boot, Electron, and Tauri are on GitHub: SciChart.JS.Examples — AdvancedLicensing
  3. Simple Server Validation requires a license with the SV (Simple Validation) feature flag. If you'd like this enabled on your order, please contact technical sales or submit a support request.
warning

Heads up: the My Account page changes that let you self-serve your Server Secret may not be live on release day, but they're following close behind. In the meantime, please reach out to support and we'll get your Server Secret to you directly.
