- 1
A developer has released an open-source project that turns the ESP32-C3, a low-cost Wi-Fi microcontroller, into a network-wide ad blocker. The small device filters ads and trackers for every device on a home network, offering a cheaper and simpler alternative to Raspberry Pi-based setups such as Pi-hole. The project is drawing attention from tech hobbyists interested in low-cost, self-hosted network tools.
- 2Open-source ESP32-C3 DNS ad blocker blocks 500,000 domains without PSRAM▼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.
