Tesser - Tracking End-to-End column lineage cross database systems

by•
Tesser automatically traces column-level lineage across databases, BI tools, and even ad-hoc queries (Slack, notebooks). Catch rogue SQL snippets before they break dashboards. Cross-database lineage (❄️-🐘- 🔍) Lightweight, query-log based (no complex setup)

Hey Builders, Tesser was born from my own pain—weeks wasted tracing broken metrics to rogue queries in Slack/notebooks. This is v1, but it already: - Traces column flow across Snowflake/BigQuery/Postgres - Flags when queries modify key metrics (like ‘revenue’) I’d love your take: Data folks: What’s your worst ‘WTF broke this dashboard?’ story? Founders: How would you create urgency for a ‘slow burn’ problem like this?
