Roadmark is a roadmap tool for teams whose plans keep changing.

Most roadmaps die the same way: a date moves, someone overwrites it, and the reason is lost. Six weeks later, nobody trusts the board, and the link you shared with a customer or an investor is quietly wrong.

Roadmark makes a change of plan a first-class object. Instead of overwriting a timeline, you branch it: the original plan and the new one both stay on the board, side by side, and every branch carries a written decision explaining why the direction changed.

It keeps itself current. Boards sync from Linear, Jira, GitHub, GitLab, Asana, Notion, monday.com, Shortcut, Azure DevOps and YouTrack โ€” or from CSV. Sync runs daily, so a link you shared months ago still shows the real plan.

Built for sharing outward. Public read-only links, password-protected or expiring links, an embeddable widget for your own site, plus comments, reactions and email follow-ups from viewers โ€” so the roadmap becomes the page stakeholders check, not another internal tool.

Also included: milestone confidence and slip history, board snapshots and diffs, PNG/SVG/PDF/PPTX export, an investor digest, a template gallery, real-time collaboration, and an audit log on Team.

Optional AI drafts milestones, writes decision notes, and runs a pre-mortem stress test of the plan โ€” with your own API key, or from an included monthly quota.

Free for up to 3 boards. Pro $15/month, Team $49/month.

Possible disadvantages of Cal.com

  • Learning Curve
    Although it is highly customizable, the plethora of options and features may result in a steeper learning curve for new users who are not familiar with such scheduling tools.
  • Limited Free Version
    The free version of Cal.com comes with limitations that may not be sufficient for growing businesses or advanced users who require more comprehensive features.
  • Dependency on Integrations
    Cal.com's effectiveness heavily depends on its integrations. Without these integrations, some users might find the tool less useful or incomplete, especially if their primary tools are not supported.
  • Support
    While open-source has many benefits, it may also mean that immediate, personalized support could be limited compared to fully commercial solutions. This might pose a challenge for users needing quick resolutions.
  • Performance
    As an open-source platform, the performance might vary depending on how it is hosted and managed. Suboptimal configurations could lead to slower performance or downtimes.

Roadmark features and specs

  • Branching timelines
    Change a plan by branching it, not overwriting it โ€” the original and the new timeline both stay on the board, side by side.
  • Decision log
    Every branch requires a written decision, so the reason a date moved survives the move itself.

  • Automatic sync
    Boards re-sync daily, so a link shared months ago still shows the current plan. Any single milestone can be force-synced.
  • Public sharing
    Read-only public links, password-protected and expiring links, and an embeddable widget for your own site.
  • Viewer feedback
    Comments, reactions and email follow on public boards โ€” no account needed to react or follow.

    Confidence level per milestone plus an append-only slip history showing every date change.

    Point-in-time board snapshots with a visual diff of what changed between them.

Questions & Answers

As answered by people managing Cal.com and Roadmark.

What makes your product unique?

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 โ€” 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.

Why should a person choose your product over its competitors?

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 โ€” 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 โ€” 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 โ€” collecting feature requests, scoring them, running customer boards โ€” Productboard and ProdPad do that, and Roadmark does not.

How would you describe the primary audience of your product?

Roadmark's answer:

Small product and engineering teams, roughly 2โ€“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.

What's the story behind your product?

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.

Which are the primary technologies used for building your product?

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.

Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling โ€” you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own โ€” Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning.
