Open-source ESP32-C3 DNS ad blocker blocks 500,000 domains without PSRAM

Original: Open-source ESP32-C3 DNS ad blocker supports up to over 500,000 domains without PSRAM

A new open-source project turns the inexpensive ESP32-C3 microcontroller into a DNS-level ad blocker capable of filtering over 500,000 domains without requiring PSRAM memory. By running network-wide ad and tracker blocking on low-cost hardware, it offers a budget alternative to devices like the Raspberry Pi running Pi-hole. The project is drawing attention from the maker and self-hosting communities interested in affordable network filtering.

Why now: The project's ability to handle over 500,000 domains on minimal hardware makes it notable for budget-conscious DIY network enthusiasts
