Hi Product Hunt! 👋 I'm the developer behind Exeria Charts. If you’ve ever tried to build a trading dashboard, a crypto tracker, or any data-heavy financial app, you probably ran into the "charting problem" pretty quickly. The standard industry approach is usually to embed a heavy, closed-source `` widget. But that comes with huge compromises: 1. They are slow and choke on high-frequency, real-time tick data. 2. They ruin the native feel and UX of your app. 3. You have almost zero control over how they render. I got tired of fighting with iframe limitations, so I decided to build a native engine from scratch. Today, we are fully open-sourcing the core of **Exeria Charts** (AGPL-3.0). It’s a high-performance financial charting library designed for self-hosted web applications. - ⚡️ Renders directly inside your DOM via a highly optimized Canvas architecture. - 📊 Ships with a unified runtime for candlesticks, lines, and volume. - ⏱ Handles sub-millisecond tick updates without blocking the main UI thread. - 🔌 We also included free data connectors (Binance, Kraken, Bybit) so you don't have to write websocket boilerplate. If you are building in Fintech, Web3, or just love tinkering with Canvas performance, I’d love for you to try it out in the Live Playground: https://exeria.dev/playground I'll be here all day answering questions about the architecture, rendering optimizations, or financial data streams. Would love to hear your feedback!
