YOUR TASK LIST IS NOT A FORECAST
A backlog can tell you what's next. It can't tell you when the plan stopped being possible.
Solo development turns every decision into a trade: scope against time, polish against cash, confidence against contingency.
Solo Dev Runway makes those trades visible before they become missed dates, exhausted savings, or a launch you weren't ready for.

One-screen signals for schedule, load, runway, sales, risk, and launch.
Weighted roadmap
Estimate work with confidence, contingency, status, and real dependencies.
26-week capacity
See the exact week where your plan asks for more hours than you have.
Budget + sales
Model conservative, base, and upside cases without building another spreadsheet.

Launch gates
Replace vibes with evidence: ownership, proof, blockers, and readiness.
SCOPE THAT TELLS THE TRUTH
Your 10-hour task is not 10 hours when you're only 60% sure.
Weighted estimates combine confidence and contingency. The roadmap rolls them into milestones, status, and a live delivery forecast—without hiding the uncertainty.
- 01 Confidence-adjusted estimates
- 02 Milestone and owner rollups
- 03 Automatic schedule variance
RUNWAY, NOT WISHFUL THINKING
See the sales target behind the creative target.
Plan fixed and variable costs, platform fees, taxes, wishlists, conversion, and unit sales in three scenarios. Know what break-even means before the launch discount.
- 01 Conservative, base, and upside cases
- 02 Gross-to-net revenue bridge
- 03 Break-even units and buffer

Questions worth asking.
Is this project-management software?+
No. It is a decision workbook. It does not replace your issue tracker; it tells you whether the plan inside it is credible.
Will it work in Google Sheets?+
Yes. It is built with standard formulas, validation, and charts—no macros or external connections.
Is the included project supposed to be failing?+
Yes. The sample is intentionally over-scoped so you can see the warning system before replacing it with your own inputs.
Can I use it for commercial games?+
Yes. One purchase covers one creator or one studio, including commercial projects. Redistribution or resale of the workbook is not allowed.
Do I need finance experience?+
No. Each input is labeled, the workbook includes a START HERE guide, and the Checks sheet flags broken or incomplete assumptions.
What if the workbook does not open?+
Reply to your Gumroad receipt within seven days. If the workbook does not open, materially differs from the listing, or cannot be used as described, the issue will be fixed or refunded.
