01 / EXPLORE THE POSSIBILITIES

A better staffing
decision starts
with a what-if.

More people won’t always mean an earlier delivery. Model the skills, availability, and joining dates that make a difference to your project.

  • Compare your current team with an alternative roster.
  • Try departures and hypothetical new members.
  • See which deliverables move, and which don’t.

Give every moving
date a clearer

File-based imports. No continuous synchronization or write-back.

PRIVACY BY DESIGN

Your plans are yours.
Keep them that way.

Unreleased features. Technical decisions. Business priorities. Your project data belongs in storage you control.

01

Local files. Real ownership.

Project data is processed in your browser and saved in a folder you choose, with browser storage for recovery.

02

Collaboration on your terms.

Open the same shared project folder with your team. Committed edits save automatically; filesystem permissions control access.

03

Clear about the connections.

Viewing needs no sign-in. Editing uses Google sign-in through Firebase Authentication. Project contents and filenames are not sent to those services.

Loading the app and public-holiday lookups can also make network requests. Use Chrome or Edge for native folder access.

GOOD TO KNOW

A few answers
before you begin.

Have a different question?

Get in touch
Is Sundial really free?

Yes. Sundial is free to use. Open the app in your browser and explore the included example. No payment is required.

Do I need to sign in?

You can view projects without signing in. To make changes, choose Login and continue with Google. Sign-in identifies the editor; it does not upload the project or grant access to its files. Read the sign-in and storage details.

Which browser should I use?

Use Chrome or Edge on a desktop for native project folder access. Detailed forms and diagrams work best in a large browser window. Follow the quick start.

Can our team work on the same project?

Yes. Each person opens the same .sundial folder on a shared filesystem with appropriate read/write access. Changes to different fields normally merge automatically; competing writes to the same field require review. Separate local copies do not synchronize on their own. Set up shared editing.

Can I use Sundial alongside Jira?

Yes. Import saved Jira CSV, JSON, or NDJSON files to analyze existing work. Sundial does not continuously synchronize with Jira or write local edits back. See the import guide and limitations.

How should I interpret forecast dates?

Ordinary forecasts simulate a declared set of estimates, dependencies, priorities, calendars, and capacity. Monte Carlo explores sampled effort estimates. Outputs depend on the quality of those inputs; dates are indicative and are not delivery guarantees. Understand what a forecast means.
