A note from stealth
Move the work off the warehouse. Prove nothing changed.
Squish is a command line tool that finds the models costing you the most on your warehouse, runs them on plain hardware you rent for cents, and proves the rows match before anything moves. Everything it writes is Iceberg on your own S3, and your warehouse reads it like any other table.
Open source under Apache 2.0. The repository goes public on September 21.
Measured, not projected
The same six models, the same data, a warehouse against the exact machine behind it.
Snowflake also bills a sixty-second minimum every time the warehouse wakes, which makes the real number $0.050 against $0.0023. We lead with the fairer one. Measured in August 2026 on a c7i.2xlarge in the same region, and reconciled against Snowflake’s own meter, which showed that 58 percent of what it billed was wake-up minimums and idle.
What we're working on
Three commands, each one leaving evidence you can check.
- squish detect
- Reads a month of your query history and prices every model, idle time included. The free configuration fixes come first, then the dollars.
- squish verify
- Runs the same SQL on DuckDB and compares both results with order-independent digests. Three verdicts: identical, equivalent at a declared precision, or an explained diff that names the columns.
- squish run
- Executes a verified model and writes the result to an Iceberg table your warehouse can read the moment it commits.
Underneath, for the platform: a writer that lands every Postgres change in Iceberg with a median commit under half a second at ten million changes, and the service that runs all of this for you. That part is not free, and it is not public yet.
