Ember is a set of free business tools for game studios. Use them to work out whether a game stands up commercially before you build it, and to keep an honest read on it once it is live.
Each tool is built to show when the answer is no, so the numbers can be checked against their inputs.
Free · No sign-up · Your numbers stay on your machineModel a game's commercial life before you commit to building it.
Check a live game against its plan, and explain the gap.
The same discipline, for games that earn after the download.
Both tools above model premium titles, where the money arrives at the point of sale. Free-to-play does not fit that shape: it runs on installs and cohorts, retention curves, conversion to payer and ARPDAU across a far longer tail. That is a different model rather than a different setting, so it is being built as its own tool rather than bolted on as a toggle.
Planning the commercial life of a game properly tends to take three people in a room: someone who knows the product, someone who can read the numbers, and someone who owns the P&L. Re-forecasting is never done once. You do it again every time reality moves.
Most studios do not have all three. So these tools include the missing parts themselves: benchmarks from real titles stand in for an analyst's context, and the model runs standard financial checks. One person can run the full analysis, and the results can be taken to a founder or a publisher.
Nothing is uploaded. Everything runs in your browser and your numbers never leave your machine, which matters when the numbers concern a game you have not announced yet.
