There is no free plan, but a 14-day trial is available.

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.
