Reverse ETL · Multiwoven
Multiwoven
Open-source, self-hosted reverse ETL platform positioned as a free alternative to Hightouch and Census.
Multiwoven is an open-source reverse ETL tool that syncs data from warehouses such as Snowflake, BigQuery, Redshift, and Databricks into business applications like Salesforce, Braze, Slack, and ad platforms. Syncs are configured with SQL or dbt models, similar to commercial reverse ETL tools, but the platform is designed to be self-hosted on the customer's own infrastructure (AWS, Azure, GCP) rather than run as a vendor-hosted SaaS. Because it is fully open source, there is no per-row or per-seat vendor fee — teams pay only their own infrastructure cost — but they also take on deployment, scaling, and connector maintenance themselves. It suits data-engineering teams comfortable operating their own tooling who want to avoid the consumption pricing of hosted reverse ETL vendors.
