ChurnLens review
A technical, self-hosted CLI for core SaaS subscription metrics and automation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ChurnLens is a self-hosted command-line tool for teams that need to process subscription-event ledgers locally. It focuses on SaaS operating metrics rather than general business intelligence, reporting MRR, ARR run rate, active customers, customer churn, net revenue churn, lifetime value, and monthly changes. Technical teams working with Stripe or CSV data are the clearest fit, particularly when local processing and automation matter more than a browser-based analytics experience.
Its standout capability is the MRR movement breakdown, which separates new, expansion, reactivation, contraction, and churned MRR. That gives teams a more useful view of recurring-revenue changes than a single MRR figure. ChurnLens also produces monthly SaaS metrics tables and can emit JSON for dashboards and automation. Its ecosystem includes Stripe, CSV, JSON, SARIF, MCP, Slack, Jira, and SIEM, while MCP server interoperability supports workflows that connect metric processing with other tools. Cross-platform installation across Windows, macOS, Linux, and Docker broadens its deployment options.
The product’s pricing model is contact sales, and commercial use requires a separate license from Cognis Digital LLC; the license grants royalty-free non-commercial use. This makes ChurnLens a better match for teams able to evaluate licensing directly than for buyers seeking transparent self-serve tiers. Its documented focus is also narrower than a full subscription analytics suite: cohort analysis and forecasting are outside its scope. Choose ChurnLens for local, scriptable reporting built around billing events and recurring-revenue movements. Choose an alternative when cohort analysis, forecasting, or a broader visual analytics environment is central to the buying decision.
