Quackback unifies customer feedback boards, feature voting, public roadmaps, release changelogs, help centers, status pages, and a multi-channel support inbox into a single self-hosted workspace that replaces Canny, Productboard, and Intercom. Product teams use its branded boards to collect feature requests and bug reports, merge duplicate submissions, and rank demand by user votes or customer segments. When a request moves into development, two-way integrations with Linear, GitHub, and Jira automatically update the card across customizable Kanban status columns or quarterly timeline views on your public roadmap. Support agents work out of a shared inbox that brings real-time Messenger web chat, inbound email threads, and durable support tickets together under one roof, complete with SLA timers, office hours, saved macros, and CSAT surveys. Conversations that uncover a feature gap convert directly into votes on existing feedback posts without losing thread context. Quinn, the built-in AI assistant, answers common questions from your Help Center articles, drafts agent replies, and exposes a Model Context Protocol server so external AI tools can triage posts or manage tickets. Once features ship, publishing a scheduled changelog entry automatically notifies every voter via email and in-app alerts. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
