Hearback — Self-Hosted Feedback + NPS Widget
Self-hosted feedback & NPS widget — pay once, own forever
Hearback is a drop-in feedback and NPS widget you host yourself. Hotjar charges $32/month ($1,152 over 3 years) for surveys; Feedbackfish charges $29/month. Hearback is $29 once — the same floating button, emoji ratings, and NPS surveys, with every response landing in an inbox on your own server.
One-line embed: self-contained JS + CSS in a shadow DOM, so your site's styles never clash with the widget
Feedback form: 1–5 emoji rating, Issue/Idea/Praise category, message, optional reply email
NPS surveys: classic 0–10 with follow-up, shown once per visitor with a frequency cap enforced in browser and on server
Auto-captured context: page URL, user agent, viewport, referrer, anonymous visitor token
Inbox with filters (mode, category, rating, status), full-text search, and a new → in progress → resolved workflow
NPS dashboard: live score, promoter/passive/detractor breakdown, weekly trend chart
Widget designer with live preview; BYO-SMTP email notifications; one-click CSV export
Spam-resistant: per-IP rate limiting + honeypot; unlimited projects and responses
