Every roadmap changes. Most tools handle that by overwriting the old plan, so three months later nobody can say what the date used to be, or why it moved.
Roadmark treats a change of direction as a branch, not an edit. Fork the roadmap at any milestone, and both timelines stay on the canvas - the route you took and the one you abandoned - each carrying a decision log explaining the call.
It stays current on its own: import from GitHub, GitLab, Linear, Jira, Shortcut, YouTrack, Azure DevOps, Asana, Notion or monday.com, then re-sync daily. A link you shared last quarter still shows today's dates, and a milestone that vanished from the source is flagged, not silently dropped.
Share it as a public page, a password-protected or expiring link, or an embedded widget. Viewers read, react, and follow by email without an account; on a paid plan they can comment too. Export to PNG, SVG, PDF, or PowerPoint.
Optional AI drafts milestones, decision logs, and roadmap stress-tests.
