Tools to track token spend, unit economics and budgets across providers, ranked by our GitHub maturity signal. Ranking method is public — see methodology. Note: maturity reflects total GitHub adoption, so large general-purpose platforms (e.g. Grafana, Sentry, PostHog) can rank high on the strength of their parent project even where their LLM-specific features are newer — read the flags and pick by your constraints. Listings are free and editorially independent; sponsorship never changes facts or ranking.
