Analytics and monitoring decision
ChartMogul
A basic subscription-metrics product (single-billing-source analytics and dashboards) is buildable by a small team using open-source building blocks, but ChartMogul’s enterprise-grade compliance, brand trust, integrations, and polished PLG features are hard to replicate — keeping the paid product makes sense for teams that need those extras.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Ingest billing events, normalize subscription lifecycles (prorations, refunds, currency), compute MRR/ARR/churn/LTV, provide REST API and scheduled exports, and a minimal dashboard for charts and segmentation.
What it still won’t have
- SOC 2 / enterprise compliance and audits
- Established brand trust and vendor relationships
- Pre-built, maintained integrations catalogue and two-way CRM sync
- Polished PLG automation, sequences, and in-product messaging
- Enterprise support and onboarding services
What remains hard
- Compliance and regulation
SOC 2 Type II certified. GDPR compliant. More information .
- Brand trust

First-year cost
Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted subscription analytics service using Node.js (Express), Postgres, Redis (jobs), and a small React frontend. In scope: webhook/CSV ingestion for Stripe, data normalization (proration, refunds, currency), persistent subscription/customer model in Postgres, background jobs to compute daily MRR/ARR/churn/time-series, a REST API for metrics and customer timelines, scheduled CSV and Slack/email reports, and a simple dashboard with segmentation and charts. Out of scope: SOC2 certification, multi-billing-system sync beyond one connector, two-way CRM sync, and enterprise onboarding. Deliverables must include error handling, input validation, unit tests for ingestion and metrics computation, and a README with deployment steps (Docker Compose) and monitoring alerts.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
