What it does
Everything you post, in one place
Stop copy-pasting the same update into five apps. Klaxon fans it out for you and keeps it all organised.
Post everywhere at once
Write your update once and send it to X*, Facebook, Instagram, Bluesky, Threads, TikTok and YouTube together — text, photos or short videos. See how →
Schedule ahead
Line posts up for later. They fire automatically at the time you set, even while you're offline. See how →
Twitch go-live auto-announce
Klaxon watches your Twitch channel and posts the moment you go live — automatically pulling in the game you're playing. See how →
Now Playing overlay
Put your current track live on stream — a one-click OBS browser source fed by Spotify or Last.fm, with a !whatsplaying command that pops it up for chat.
A kit of stream overlays NEW
Drop-in OBS browser sources: a live sub counter & goal bar (Tier 1), plus a spin wheel, emote rain, a prize tombola and a follow-me social bar (Tier 2).
Your own chat bot NEW
Commands, timers and !so shoutouts that post under your own named bot account — shoutouts even play one of their clips on an overlay. Tier 2.
Stream Deck buttons
Turn any post into a one-tap Stream Deck button. Press it, and it's live across your channels.
Templates & variables
Save reusable posts and drop in live values like {game} and {title} that fill themselves in.
Your keys, encrypted
You connect your own social accounts. Credentials are encrypted at rest and Klaxon only uses the official platform APIs.
Works with
Your whole lineup
* X (Twitter) needs your own X developer API keys — X's API is self-serve and paid at higher usage. Facebook, Instagram, Bluesky, Threads, TikTok and YouTube connect in one click.
