Monte Carlo monitors pipelines. Lighthouse monitors your KPIs.
They solve different problems. If you need to know when your revenue drops, when DAU falls, or when a conversion metric moves, Lighthouse is what you're looking for.
Monte Carlo monitors data infrastructure health: whether pipelines are running, tables are fresh and schemas haven't broken. Lighthouse is a business metric monitoring platform: connect read-only credentials, describe a KPI in plain English, and get a Slack alert when revenue, DAU or conversion changes.

Two different problems. Two different tools.
Most teams looking for a Monte Carlo alternative are actually looking for a different product entirely.
Monte Carlo is for this
- A table in your pipeline has unexpected null values
- A schema change broke a downstream model
- Your dbt job didn't run and data is stale
- Row counts dropped in a raw table
- Data lineage audit and pipeline reliability
Lighthouse is for this
- Revenue dropped 20% vs last Tuesday: alert the team
- DAU for mobile users is below the 4-week average
- Checkout conversion rate fell: send to #product-alerts
- Transaction volume is unusually low this hour
- Any business KPI moved outside its normal range

Common questions
Do I need both Monte Carlo and Lighthouse?
Possibly. Monte Carlo monitors your data infrastructure health: whether pipelines are running, tables are fresh, schemas haven't broken. Lighthouse monitors business outcomes: whether your revenue, DAU, or conversion rate changed. Teams with mature data infrastructure sometimes use both for different audiences.
What if I just want to monitor business KPIs from Snowflake?
Lighthouse is the right choice. You connect with read-only credentials, describe a KPI in plain English, and get a Slack alert when it changes. Setup takes 10 minutes. No pipeline integrations, no lineage mapping, no enterprise procurement.
Is Lighthouse a data observability tool?
No. Lighthouse is a business metric monitoring platform. Data observability tools monitor the health of your data infrastructure. Lighthouse monitors the business values that infrastructure produces. These are complementary, not competing, categories.
How is Lighthouse priced compared to Monte Carlo?
Monte Carlo is enterprise-priced with annual contracts typically starting in the six figures. Lighthouse has a free forever tier and paid plans starting at $49/user/month, no sales call required.
