Forest Fire Classifier is a tiny web app for detecting fire, smoke, fire+smoke, or no-fire in images. Upload a forest photo and get a prediction in ~500 ms. v2 is rebuilt with Next.js, TypeScript, and TensorFlow.js running server-side for consistent performance. Images are processed in memory only – nothing is stored. It’s open source, privacy-first, and built to showcase how far “college project → real product” can go.
