Roadmark's answer

Roadmark treats a change of plan as something you record, not something you erase. Every roadmap tool lets you drag a milestone to a new date — and the old date, along with the reason it moved, quietly disappears. In Roadmark you branch the timeline instead: the original plan and the new one both stay on the board, side by side, and the branch carries a written decision explaining the change. Six months later the board answers "why did this slip?" on its own, without anyone digging through Slack.

The other half is that the board keeps itself current. It syncs daily from Linear, Jira, GitHub, GitLab, Asana, Notion, monday.com, Shortcut, Azure DevOps and YouTrack, so a link you shared with a customer or an investor doesn't silently stop being true.

Roadmark's answer

Three concrete reasons.

Branching with a decision log. Productboard, Aha! and Roadmunk all show you the plan as it stands today. Roadmark shows you how it got there — every pivot kept, each with the reasoning attached.

Pricing that doesn't punish sharing. Pricing is flat per workspace, not per seat. Team includes unlimited members, and read-only viewers never consume a seat at all — so putting the roadmap in front of customers and stakeholders costs nothing extra.

Built to be shared outward. Public read-only links, password-protected and expiring links, an embeddable widget, and comments, reactions, and email follow for viewers without an account.

Where Roadmark is not the answer: if what you need is a feedback and prioritisation suite — collecting feature requests, scoring them, running customer boards — Productboard and ProdPad do that, and Roadmark does not.

TimeGlide's answer:

Competitors are bulky and slow. Timeline is slick, modern and fast.

Roadmark's answer

Small product and engineering teams, roughly 2–20 people, where the plan changes often and someone outside the team keeps asking where things stand: founders reporting to investors, product managers at startups, agencies and consultancies reporting to clients, and indie makers running a public roadmap.

TimeGlide's answer:

Anyone that enjoys laying data out temporally and precisely will benefit from this app. That could be the hobby historian that wants to have a clearer picture of historical events or the project planner that likes to be able to move from overview to detail, quickly.

Roadmark's answer

Roadmark was built in 2026 around one observation: roadmaps don't fail because teams plan badly; they fail because plans change and the tools only store the latest version. A date moves, the bar gets dragged, and the reason is gone. Six weeks later the board is no longer true, and nobody trusts it enough to look.

So the plan itself became the thing worth versioning. Keep the old timeline, branch to the new one, attach the decision to the branch. Sync, public links, and the decision feed all exist for the same purpose: to keep that history accurate without anyone maintaining it by hand.

Roadmark's answer

Next.js 15 (App Router) and TypeScript on the front end, Tailwind CSS 4 for styling, Supabase (PostgreSQL, Realtime and Auth) as the backend, and Vercel for hosting. Tested with Vitest and Playwright.
