Imagine: an old router for 2000 ₽ blocks ads, shares a VPN, works as a Mesh system and doesn’t slow down even with 50 devices.
This is not magic — this is OpenWRT.


🏠 Who needs OpenWRT

OpenWRT turns an ordinary router into a mini-server. If you have at least one item from the list — it’s definitely time to try it:

  • Want AdBlock for the whole house
  • Need a VPN without a subscription
  • Have an old router lying around
  • Like to tinker with settings

90% of users install OpenWRT — and forget about the router forever.


⚡ What OpenWRT can do

  • AdBlock — ad filtering at the DNS level
  • SQM (QoS) — get rid of lags in Zoom and games
  • WireGuard / OpenVPN — fast and secure VPN
  • Mesh Wi-Fi — combines multiple routers
  • USB modems — works even with 4G dongles
  • Torrents 24/7 — without a PC turned on
