Welcome to OtaHub

OtaHub is a premium, serverless Over-The-Air (OTA) firmware distribution platform designed for ESP32 microcontrollers. Built on Cloudflare's serverless edge and R2 object storage, OtaHub delivers high-speed, secure, and low-latency firmware streaming globally.

Key Architecture Bounds

Secure Streams

Devices communicate over HTTPS/SSL using project-specific API keys. Payload streams are protected by Cloudflare Edge policies.

Core Isolation

The companion Arduino library runs checks on a background thread pinned to Core 0, keeping Core 1 entirely free for your application loop.

Device Compatibility

The platform is fully optimized for all standard ESP32 development modules (ESP32-WROOM, WROVER, S2, S3, C3) compiled via the Arduino framework or ESP-IDF with Arduino component wrappers.
