Upvote Widget

One-tap upvotes, one per user

Set up

The same loader also powers comments and any other widget. Or drive it from code, login uses the shared Google identity: 

BootSignalUpvote.init({ siteId: 'YOUR_SITE_ID', threadId: 'page-key', lang: 'en' })
BootSignalUpvote.signIn()           // Google popup → shared uid
BootSignalUpvote.onAuthChange((user) => console.log(user))

Upvotes require sign-in (one per user). The same widget works across the whole family.

Pricing

Pricing is a flat per-site subscription: 1/mo or 10/yr in credits (yearly ≈ two months free). Writing upvotes requires an active subscription; while subscribed, usage is unlimited with no per-use charges. Pay with shared credits (top up at accounts.mrlatte.net); auto-renew can be turned off in your dashboard. Credits are shared across all BootSignal services and never expire. See pricing details →
