Sifflet
Data observability platform that combines monitoring, field-level lineage, a data catalog, and AI agents for root cause and incident triage.
Data teams on Snowflake, BigQuery, or Databricks who need lineage that shows business impact, not just failed tests.
Teams that only need a few dbt tests, or very small stacks where a catalog and lineage graph will sit unused.
Verdict
Sifflet is a data observability platform founded in Paris in 2021; the name is French for whistle. Data teams use it to watch tables for freshness, volume, and schema changes, trace a broken number back through lineage, and tell the people who use a dashboard when it is wrong. It stands out because it puts monitoring, lineage, and a catalog in one place, so data engineers and business users look at the same picture when data breaks.

Review Excerpts
Below are excerpts from public reviews. Our team scoured public reviews, forums, and chat rooms to get a balanced view of customers' experience with this company. Paid reviews and pay-for-play sites such as Clutch were excluded.
“Having the visibility of our DBT transformations combined with full end-to-end data lineage in one central place in Sifflet is so powerful for giving our data teams confidence in our data, helping to diagnose data quality issues and unlocking an effective data mesh for us at BBC Studios.”
“Using Sifflet has helped us move much more quickly because we no longer experience the pain of constantly going back and fixing issues two, three, or four times.”
“It is not plug and play. We had to spend a couple of weeks tuning the anomaly monitors on our noisiest tables before the Slack alerts were worth reading.”
