180 observed daily rows. Missing days are not fabricated.

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: 1
  • Stars gained: 90d: 11961

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

100500
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: 13
  • 30% Closure: 0
  • 20% Shipping: 0
  • 10% Liveness: 72
  • 10% Support burden: 41

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.

Reliability breakdown

What drives the reliability score

Component scores measured daily from GitHub activity (2026-07-19).

Continuity30% of headline13

Activity on 3 of 90 tracked days in the last 90 and 0 of 30 in the last 30.

Activity pulse
Closure30% of headline0

Merged 0 of 3 PRs opened and closed 0 of 1 issues opened over the last 90 tracked days — PR flow carries 55% of this component, issue flow 45%.

PRs merged (90d)PRs opened (90d)Issues closed (90d)Issues opened (90d)
Shipping20% of headline0

0 releases in the last 180 days, 0 in the last 90 and 0 in the last 30 — a steady cadence scores highest.

Releases
Liveness10% of headline72

Last push 40 days ago — freshness decays as pushes age (roughly halves every 83 days without a push).

Daily ratio — a gap means nothing was opened that day

How this works: each day's value is issues closed that day ÷ issues 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 issues than arrived that day.

About Karma

Karma is presented as a JavaScript test runner, aimed at helping developers execute tests as part of web development workflows. Test runners matter because they provide the layer between test code and actual execution, making it easier to automate feedback during development. Karma is most relevant when teams want a defined runner for JavaScript tests, especially in environments where browser behavior is part of what needs to be exercised. In broader testing stacks, it serves as infrastructure for running tests reliably rather than defining the tests themselves.
