# Two-Way Sync Salesforce and Postgres

This guide gets you from zero to hero in minutes and addresses anyone willing to try out the magic of Stacksync, even without a database or Salesforce instance. This tutorial walks you through all the steps to get your Postgres Database for free and your Salesforce developer instance (free forever too!). If you already have any of the above, feel free to skip the step to the next one ;)

Once you've created your Stacksync account at [www.stacksync.com](https://www.stacksync.com), you're ready to go!

Here are three steps, each taking about four minutes:

1. [Create a PostgreSQL database with Supabase (free forever)](/two-way-sync/guides/two-way-sync-salesforce-and-postgres/create-a-postgres-database-with-supabase-free-forever.md)
2. [Create a Salesforce Developer Instance (free forever)](/two-way-sync/guides/two-way-sync-salesforce-and-postgres/salesforce-developer-instance-free-forever-create-yours-in-4-minutes-2025.md)
3. [Set up a sync between your Salesforce and Postgres services with Stacksync](/two-way-sync/guides/two-way-sync-salesforce-and-postgres/create-a-sync-between-supabase-postgres-and-salesforce.md)
