Pricing Formula

Disclaimer: these prices are subject to change, because we are not certain yet if we have the correct cost formulas with respect to our web hosts, and the community might for instance vote for having more performant hosting, which will cost more.

  • The current (refresh page to update) Django server load (with 5-minute resolution) is:
    $\ \Large L = 0.76.$

  • Django hosting currently costs approximately:
    $\ \Large D = \$0.03/\text{hour}.$

  • Neo4j (graph database) hosting currently costs approximately:
    $\ \Large N =\$0.15/\text{hour}.$

  • Since the cost to you for $t$ hours of search time $S$ is estimated to be:
    $$\ \Large S(t) = (1 +L)(N+D)t. $$

  • For each $C$ dollars in Neo4j/Django query credits you purchase, the site engineers take a $5\%$ cut while another $5\%$ goes to fund the community of creators (see "Payout" below). Setting $\frac{9}{10} C = S(t)$, we can solve for $t$ to get:
    $$\ \Large t = \frac{9}{10(1 + L)(N + D)} C.$$

  • For example $\$5$ of credits should yield you about 0.5 hours of Neo4j/Django query time, at this current server load $L$.
