Marathon-Timer
Free with no paid tier and no commission. Reads Twitch, YouTube and Kick, and pulls donations from Streamlabs, TipeeeStream, StreamElements, NineStore and Ko-fi onto the same clock. Goals with their own overlay and a public page you can paste in chat. Interface in 14 languages, and you can hand the controls to anyone you choose without sharing your account.
🔊
Blerp
The widest platform list, TikTok and Rumble included. Appearance is limited to a text colour and a background colour. Their own comparison says some features require a subscription without saying which, and their subscription page covers soundboards, TTS and alerts without mentioning the timer or the goals.
🧩
StreamElements
Bundles overlays, alerts and a chatbot, with a timer among them. Subs are read from Twitch only, and pausing for a break is handled by hand.
💧
Streamlabs
Comes with Streamlabs Desktop rather than the other way round. Twitch and YouTube, no Kick, and the premium features sit behind the Ultra plan at $19 a month.
⚙️
Mix It Up
An automation tool that can also drive a timer. Expect to build the workflow yourself; there is no ready-made subathon setup.
🤖
Streamer.bot
Free and open source. Everything is yours to wire, the timer included — there is no subathon feature out of the box.
🌙
Nightbot
A chat bot, not a timer. You can fake a countdown with custom commands, but there is no visual clock for your overlay.
