About SQLise

SQL is the universal language of data. SQLise helps teams understand the systems built on top of it.

Every dashboard, every model, every metric eventually traces back to a SQL query someone wrote. When that query is wrong — a bad join, a missing GROUP BY, a fan-out that doubles your revenue — it doesn't throw an error. It just lies, quietly, until someone catches it. SQLise exists so that you can see what your SQL is actually doing before that happens.

Parse. Trace. Explain.

Three steps. Parse any SQL across SQL Server, Snowflake, PostgreSQL, MySQL, and Oracle. Trace every column from source to destination through joins, CTEs, and transformations. Explain what the query is doing in plain English with Query Lens™.

Who it's for

Data engineers debugging warehouse models. Analytics engineers tracing dbt mart columns. Analysts who inherited someone else's 400-line view. Snowflake practitioners auditing pipelines. Anyone who has ever asked "where does this number actually come from?"

The SQLise suite

• SQLise Studio — The interactive lineage workspace — paste SQL, see the graph, share the result.
• SQLise Impact — Pinpoint everything downstream of a column, table, or view before you ship a change.
• SQLise Parser — The dialect-aware engine behind every Studio render — five engines, one normalised graph.
• SQLise Copilot — Plain-English explanations of any query, plus targeted diagnostics with Query Lens™.

How it's different

• Instant — no install, no warehouse credentials, no sign-up to start.
• Column-level — Column Trace™ follows every dependency, not just object-to-object edges.
• Multi-dialect — SQL Server, Snowflake, PostgreSQL, MySQL, Oracle.
• Shareable — generate a link, hand it to a teammate, move on with your day.
