Quick answer: KPIs, or key performance indicators, are the small set of metrics you designate as the most important measures of your game's success and health. Rather than tracking everything, you choose the few numbers, retention, stability, reviews, conversion, that genuinely reflect how the game is doing, so your attention goes to what actually matters.
Modern games can measure almost anything, which creates a trap: drowning in metrics while losing sight of what matters. KPIs are the antidote, the deliberate choice of a few key indicators that genuinely reflect your game's health and success, so you watch those rather than a hundred numbers of varying relevance. For an indie with limited time, choosing the right KPIs is essential, because you cannot watch everything, and the few you do watch should be the ones that tell you whether the game is actually doing well.
What Makes a Metric a KPI
A KPI is a metric you have designated as a key indicator of performance, one of the few numbers that genuinely matters for understanding whether your game is succeeding. The 'key' is the point: not every measurable thing is a KPI, only the ones that meaningfully reflect health and success. A good KPI is one where, if it moves, you genuinely care and would act. The discipline is choosing a small, focused set rather than treating every metric as equally important.
KPIs differ by game and goal, but for indies they commonly include: retention (D1, D7, are players staying?), stability (crash-free rate, is the game reliable?), reception (review score, what do players think?), reach (wishlists pre-launch, active users post-launch), and conversion (for funnels or monetization). The right set is the handful that, taken together, tell you whether the game is healthy and succeeding on the dimensions you care about.
Why Focus on a Few KPIs
The value of KPIs is focus. With limited time and attention, especially as an indie, you cannot meaningfully watch and act on dozens of metrics. Choosing a few KPIs concentrates your attention on the numbers that matter most, so you actually notice and respond when they move, rather than diffusing your attention across so much data that nothing stands out. KPIs are a forcing function for clarity about what success means for your game.
Well-chosen KPIs also align effort. When you know your key indicators, you can prioritize work by its likely effect on them, does this improve retention, stability, reviews? This connects daily decisions to the outcomes you care about. Without KPIs, it is easy to optimize random metrics or none at all; with them, you have a clear scoreboard for whether the game is moving in the right direction.
Stability as a Core KPI
Among the KPIs an indie should track, stability deserves a place that is often underweighted. Crash-free rate is a true key indicator because it both reflects and drives other KPIs: an unstable game crashes players out of their first session (hurting retention), generates negative reviews (hurting reception), and drives refunds and churn. Stability is upstream of much of what determines success, which makes it a high-leverage KPI to watch and improve.
Bugnet provides the crash and bug data behind a stability KPI, your crash-free rate and the specific crashes driving it, surfaced and ranked by impact, plus the player-facing reception side through reviews and reports. Tracking stability as a KPI, alongside retention and reception, and connecting it to the actual issues you can fix means your KPI is not just a number to watch but a lever to pull: when your crash-free rate is a designated KPI, the crashes dragging it down become priorities, and improving it ripples into the retention and review KPIs it influences. Choosing the right few KPIs, and including stability among them, keeps your limited attention on the measures that genuinely determine whether your game thrives.
KPIs are the few numbers that actually tell you if your game is healthy, retention, stability, reviews. Pick a focused set, and don't leave crash-free rate off it.
