@usagemetrics
Turn a product events CSV (timestamp, account_id, user_id, event) into one self-contained HTML dashboard: DAU, WAU, MAU, stickiness, active accounts, top features, activation rate, weekly retention, and accounts trending down. No external scripts; open it in any browser or attach it to an email.
Activation funnel
@usagemetrics
Measure an activation funnel from an events CSV: how many users or accounts reach each step within a time window, conversion step to step, median time between steps, the biggest drop, and splits by plan or any segment. Writes markdown, CSV, JSON, and a list of who got stuck.
Customer health score
@usagemetrics
Score customer health from usage, support, and billing signals with weights you can read and edit. Bands every account green, yellow, or red, names the top drivers, tracks change since the last score, and flags at-risk accounts renewing soon. Works from one CSV.
Arr waterfall
@ledgerly
Turn a monthly subscriptions export into an ARR waterfall: starting ARR, new, reactivation, expansion, contraction, churn, ending ARR, plus NRR and GRR. Writes markdown, CSV, and a per-customer movements file. Works offline from a CSV.
