Crunchy Bridge
activeby Crunchy Data (Snowflake) · since 2020 · also known as Crunchy Data Bridge, Crunchy Bridge for Analytics
Crunchy Data's developer-friendly managed Postgres across AWS, GCP and Azure, now owned by Snowflake.
Overview
Crunchy Bridge is the managed PostgreSQL service from Crunchy Data, a long-time Postgres contributor whose team joined Snowflake in 2025 and now builds Snowflake Postgres. Bridge runs community Postgres on AWS, Google Cloud or Azure, with superuser-level access, a broad extension set (PostGIS, pgvector, pg_cron, pg_partman), per-minute billing and strong support from Postgres experts. Its analytics offering embeds a DuckDB-based engine to query and write Iceberg and Parquet data in object storage from Postgres. Bridge remains on sale and supported, but new feature investment is now directed at Snowflake Postgres, so weigh the roadmap if you are starting fresh.
Strengths & trade-offs
Strengths
- +Runs on AWS, GCP or Azure with cross-cloud replicas
- +Superuser-level access and a wide extension catalog
- +Postgres expert support from long-time core contributors
- +Iceberg/Parquet analytics from Postgres via an embedded DuckDB engine
