## Description

blockmaxxing removes ads from Twitch — including the stream-level (server-side inserted) ads that ordinary blockers can't touch — entirely on your device.

Twitch stitches ads directly into the video stream, so simply hiding an element or blocking a URL doesn't work. blockmaxxing runs inside the player, detects the ad-stitched segments in the stream playlist, and swaps in an ad-free stream.

FEATURES
• Stream-level (SSAI) ad removal — the approach that actually works on Twitch
• Toolbar badge showing how many ads were blocked on the current tab
• Per-channel whitelist — support your favorite streamers by letting their ads play
• Optional "mute during ad swap" to avoid any ad audio
• Optional on-device diagnostics you can inspect and export
• Works on Chrome and Edge

PRIVATE BY DESIGN
• No backend, no analytics, no accounts
• No data ever leaves your device
• Talks only to Twitch's own APIs
• Open source (MIT) — read every line

HONEST NOTE
No Twitch ad blocker is perfect. Twitch changes how it serves ads frequently, so occasional ads may appear until the extension is updated. blockmaxxing blocks the large majority of ads and is designed to update quickly.
