ChurnLens vs OpenMogul

ChurnLens is a self-hosted SaaS metrics tool for calculating MRR, churn, and LTV from Stripe or CSV data. Its full report includes current MRR, ARR run-rate, active customers, average customer churn, and monthly figures such as net-new MRR and LTV. The `mrr` command breaks the latest month’s MRR movement into new, expansion, reactivation, contraction, and churned amounts. Reports can return JSON and use a chosen currency label, with USD as the default.

ChurnLens can recompute metrics from ledger updates and publish JSON to a BI or dashboard pipeline. It also lists SARIF output for code scanning, an MCP server for AI agents, and webhook forwarding for SIEM, Slack, and Jira. The README describes use through MCP, JSON piped into agents or LLMs, or CI with exit codes and SARIF. Installation options include pip, pipx, uv, Docker, Homebrew, and a shell script. It requires no account. The source-available license permits personal, internal evaluation, research, and educational use; commercial or production use requires a separate license. Pricing is on request.

OpenMogul provides subscription analytics for SaaS businesses, including monthly and annual recurring revenue, churn, and customer lifetime value. It tracks new business, expansions, contractions, and churn in real time, presenting results in a visual dashboard with interactive charts and graphs. OpenMogul is described as fully self-hosted: data stays on the user's servers and can be exported at any time. It is also available as a web product and API. The REST API covers data sources, customers, plans, subscriptions, invoices, metrics, activities, and a health-check endpoint. Requests use HTTP Basic Auth with an API key. The site describes the API as compatible with ChartMogul and says existing integrations can work after changing the base URL; Stripe is given as an example data source. OpenMogul is open source under the MIT License. Its Free plan is listed at free, with no per-seat charges or usage limits, and the site says there are no hidden fees.
