Gives every browser on the machine ad and tracker blocking, including WebKitGTK ones like surf that have no extension mechanism and so cannot run uBlock Origin. 80,002 rules from the StevenBlack list load in 82ms and sit in 9MB resident. A proxy receives CONNECT doubleclick.net:443 before any TLS handshake, so a blocked host is refused without decrypting anything. Ads and trackers are third-party hosts, which is why host-level refusal captures nearly all of the weight while leaving traffic sealed: no certificate authority in the trust store, no CA private key on disk, and no visibility into a bank session this program merely relays. What that cannot do is cosmetic filtering and first-party ads, which need TLS interception. That is omitted deliberately, and the README records the reasoning and where the seam would be, rather than leaving it looking like an oversight. CONNECT to a blocked host 403, refused before the handshake CONNECT to anything else tunnelled bytes, untouched plain HTTP to a blocked host 204, so a beacon looks empty not failed plain HTTP otherwise forwarded and relayed Matching is by domain suffix, so a rule for doubleclick.net covers stats.g.doubleclick.net; lookups walk the labels of the requested host rather than the list. Hosts files, bare domain lists and the ||domain^ subset of Adblock syntax are accepted, while rules needing response inspection are skipped rather than half-applied. Allow rules win at any depth, and IP addresses are never blocked, since hosts files are full of them as addresses. Lists cache for a week and fall back to a stale copy when a refresh fails. Connections are capped at 96 with a Drop guard releasing the slot even on panic, and only the loopback interface is bound.
