Streamathon Widget for OBS subathon timers
Run a live countdown timer in OBS for subathons, donation marathons, membership marathons and other long streams where viewer support adds time.

Let viewer support add time
Choose which events add time to the timer, then set how many seconds each sub, gift, tip, donation or reward is worth.
Subs, resubs and memberships
Add time for Twitch subs and resubs, YouTube members, Kick subs, Ko-fi subscriptions and Patreon memberships.
Gifted subs and gifts
Reward bigger support by adding time for gifted subs, gifted memberships, TikTok gifts and YouTube gifts.
Bits, channel points and rewards
Let Twitch bits, channel point redeems and reward redemptions add time to the timer.
Tips and donations
Add time from StreamElements tips, Streamlabs donations, Ko-fi donations and other supported donation events.
Control the timer while you are live
Keep the OBS widget clean for viewers and use Synchra controls to manage the timer behind the scenes.
Start, pause and resume
Open the Streamathon controls when you go live, then start, pause or resume the timer whenever the stream needs it.
Add or remove time manually
Add seconds or remove seconds yourself when you need to fix the timer or make a manual adjustment on stream.
Restart or reset the timer
Restart the countdown with the current setup or reset it when you are preparing for another stream.
Set a maximum end time
Use an optional end time when you want a hard limit so viewer activity cannot push the stream past a specific date and time.
Choose what viewers see
Show or hide the timer title and status text, such as paused or ended, so the widget stays clean in your overlay.
Style it for your overlay
Change colors, font, size, padding, border, rounded corners and custom CSS so the timer matches your stream.
