Hotness formula

40% Hot today + 40% Hot this week + 20% Breakout.

40% Hot today: 1
40% Hot this week: 1
20% Breakout: 1
Stars gained: 1d: 0
Stars gained: 7d: 0
Stars gained: 14d: 0
Stars gained: 30d: 0
Stars gained: 90d: 39

Per-day formula: 0.40 × Hot today + 0.40 × Hot week + 0.20 × Breakout.

Same-day multiplier = stars 1d ÷ max(1, stars 7d ÷ 7)
Weekly multiplier = stars 7d ÷ max(1, stars 30d ÷ 30 × 7)
Fortnight multiplier = stars 14d ÷ max(1, stars 90d ÷ 90 × 14)
Hot today = clamp(70 × log-scale(stars 1d, 1000) + 30 × breakout-scale(same-day, 4))
Hot week = clamp(75 × log-scale(stars 7d, 5000) + 25 × breakout-scale(weekly, 3))
Breakout = clamp(35 × breakout-scale(same-day, 4) + 40 × breakout-scale(weekly, 3) + 25 × breakout-scale(fortnight, 2.5))

Weekly average

Full metrics details

Derived from the displayed continuity, closure, shipping, liveness, and support-burden components.

180 observed daily rows. Missing days are not fabricated.

Reliability formula

30% Continuity + 30% Closure + 20% Shipping + 10% Liveness + 10% Support burden.

30% Continuity: 34
30% Closure: 76
20% Shipping: 22
10% Liveness: 100
10% Support burden: 95

Per-day formula: 0.30 × Continuity + 0.30 × Closure + 0.20 × Shipping + 0.10 × Liveness + 0.10 × Support burden.

Continuity = 35% active ratio 90d + 20% active ratio 30d + 15% PR efficiency 90d + 10% PR efficiency 30d + 10% liveness + 10% observed-history coverage
Closure = 55% PR merge efficiency 90d + 45% issue close efficiency 90d
Shipping = 100 × (20% × release ratio 30d + 30% × release ratio 90d + 50% × release ratio 180d); ratios are releases ÷ 2, 6, and 12, capped at 1
Support burden = 100 − 2 × open issues per 1,000 stars
Liveness = 100 × exp(−pushed days ago ÷ 120)

Stars, issues, pull requests, and releases are daily observations. Pushed-days and license are repository snapshot-derived inputs and are not independent historical GitHub events.

Daily ratio — a gap means nothing was opened that day

How this works: each day's value is pull requests closed that day ÷ pull requests opened that day. Days when nothing was opened render as gaps — never a rolling average or a made-up zero. Values above 1 mean the project closed more pull requests than arrived that day.

About Ava

Ava is a Node.js test runner built to help developers work with confidence. In the JavaScript ecosystem, test runners define a large part of the day-to-day developer experience because they influence how quickly teams can validate changes, structure suites, and keep quality visible during iteration.

Ava fits the testing category rather than broader browser automation or full-stack integration tooling. That focus makes it most relevant when teams want a clear, dedicated test runner for JavaScript and Node.js code. It sits in the part of the stack where maintainability, speed, and test clarity often matter more than broad platform abstraction.

If you are evaluating JavaScript testing tools, Ava is worth considering for projects that want a streamlined Node-oriented testing experience. It is especially relevant when the goal is dependable feedback during development rather than a large, multi-purpose automation platform.
