Build a Standalone Web Server That Stores and Serves Files Directly from the ESP32

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Your ESP32 will act like a tiny web hosting service — it stores HTML and JSON files right inside its flash memory using SPIFFS, then serves them to any device connected to the same WiFi network. You can create a button-controlled status page, toggle LEDs through the browser, or serve sensor data as a JSON endpoint, all without an SD card or external storage.

What You'll Build

By the end of this project, you’ll have a fully functional standalone web server. You’ll write a simple HTML page and a JSON data file, upload them to the ESP32’s internal flash, and access them over WiFi using a phone, tablet, or laptop. The onboard buttons let you switch pages or trigger LED states, turning your breadboard into an interactive IoT node.

What You'll Learn

• Format ESP32 flash memory with the SPIFFS file system and upload files using the Arduino IDE
• Program an asynchronous web server that handles GET requests and serves static content
• Link physical inputs (buttons) and outputs (LEDs) to the web interface for real-time control
• Structure a JSON API on a microcontroller that returns live data to any connected client

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

ATL Tinkering Lab participants and CBSE students (Class 6–10) who want to move beyond basic LEDs into real IoT. Hobbyists aged 10–15 exploring embedded web servers for the first time. And beginners at Smart India Hackathon junior tracks or B.Tech introductory labs who need a solid, hands-on introduction to SPIFFS and asynchronous WiFi servers on the ESP32.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
