BootSignal: Site Widgets

BootSignal is an embeddable widget platform. One line of script adds features like comments, ratings and countdowns to any website, with sign-in and storage included. You do not run a server of your own, and your host page keeps its own code.

WHAT YOU GET
- 24 drop-in widgets: comments, ratings, reactions, upvote, polls, guestbook, feedback box, newsletter, countdown, announcement bar, popup notice, cookie consent, reading progress, table of contents, view count, gallery, lightbox, before and after slider, image magnifier, image mask paywall, share bar, split flap board, mindmap viewer and mindmap editor.
- A dynamic OG image API: put one URL in your og:image meta tag and the social card is rendered on the server.
- 30 free tools, no sign-in required: QR code generator, D-day calculator, password and UUID generator, JSON formatter, hash and JWT tools, regex tester, timestamp converter, text diff, CSV and JSON converter, color, contrast and gradient tools, cron helper, pomodoro timer, stopwatch and more.
- Dashboard: register your sites, turn each widget on or off, copy the install snippet, check subscription status and export newsletter subscribers.
- Pricing: subscribe per site to just the widgets you use, monthly or yearly. The utility tools stay free.

Works anywhere you can paste a line of script, including WordPress, Tistory, Cafe24, Imweb, Shopify, Wix, Squarespace, Webflow, Ghost and Blogger.

The app is a companion to bootsignal.com and needs a network connection. The interface is available in English, Korean, Japanese, Simplified Chinese and Traditional Chinese.
