180 observed daily rows. Missing days are not fabricated.
30% Continuity + 30% Closure + 20% Shipping + 10% Liveness + 10% Support burden.
Per-day formula: 0.30 × Continuity + 0.30 × Closure + 0.20 × Shipping + 0.10 × Liveness + 0.10 × Support burden.
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
Component scores measured daily from GitHub activity (2026-07-19).
Activity on 4 of 90 tracked days in the last 90 and 1 of 30 in the last 30.
Merged 1 of 3 PRs opened and closed 7 of 0 issues opened over the last 90 tracked days — PR flow carries 55% of this component, issue flow 45%.
2 releases in the last 180 days, 2 in the last 90 and 2 in the last 30 — a steady cadence scores highest.
Last push 23 days ago — freshness decays as pushes age (roughly halves every 83 days without a push).
Open-issue load isn't tracked for this repo yet.
Modeled — lower is better; concentration of commits in few maintainers. Contributors graph

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.

Per-day formula: pull requests closed that day ÷ pull requests opened that day; blank when nothing was opened (a gap, not a zero).

Flamebearer is built around one clear strength: making flame graph analysis feel fast. For Node.js and V8 performance work, that matters because developers often need to compare runs, inspect hotspots, and move through profiling data without waiting on heavy interfaces. Its emphasis on speed and clarity makes it a useful option for JavaScript teams that want profiling visuals to support investigation rather than slow it down.
