Organizations using Heroku Connect for Salesforce-Postgres synchronization face escalating operational challenges: high and opaque pricing models often costing $2,500-$3,000 monthly, performance degradation at higher data volumes with sync delays during busy periods, and limited scope restricting integration to only Salesforce and Heroku Postgres. These technical limitations force engineering teams to seek affordable Heroku Connect replacements that provide real-time bi-directional synchronization across operational systems.
The fundamental challenge extends beyond simple data movement: modern enterprises require sub-second synchronization between CRMs, ERPs, and operational databases with automated conflict resolution and enterprise-grade security. When CRM, ERP, and database records are out of sync, the consequences range from operational inefficiencies and poor customer experiences to flawed decision-making. Traditional approaches create operational fragmentation where data inconsistencies directly impact business continuity.
Heroku Connect's architectural constraints create several critical operational challenges for data-dependent organizations:
Heroku Connect polls data changes at regular intervals from both Salesforce and Postgres, designed to be eventually, but not immediately, consistent with Salesforce. With read-write mappings, Postgres may temporarily fall out of sync when multiple updates are made to the same field, especially during busy periods. This polling-based architecture prevents real-time operational decision-making.
Some sync issues fail silently and aren't flagged, including mismatched data types, formatting issues, timezones instead of timestamps, or using 1/0 vs. boolean flags. To fix this, teams need to build entire data extraction and consolidation pipelines - a manual effort but the only way to guarantee valid data syncing.
While Heroku Connect works for basic two-way syncing, most teams want to trigger actions based on data changes like sending welcome emails when new contacts are created, but it doesn't have built-in support for event triggers or external actions. Achieving this requires custom code to detect changes in Postgres and handle triggers manually, adding complexity that could interfere with Heroku Connect's operation.
Stacksync directly addresses Heroku Connect's architectural limitations through purpose-built bi-directional synchronization technology. It is engineered specifically for real-time, bi-directional synchronization between operational systems, designed to maintain low latency even at high volumes.
Technical Superiority Over Heroku Connect
Real-Time Performance Architecture:
Cost Optimization and Transparency: Stacksync's pricing is based on Monthly Active Rows (MAR), a transparent metric that is simpler and can be more affordable than Heroku Connect's model, making enterprise-grade sync accessible to small and medium-sized businesses. The pricing model is much more transparent and flexible - you only pay for the number of records that you synchronize, with only monthly active rows counted.
Expanded Connectivity Beyond Heroku's Limitations: Beyond Salesforce and PostgreSQL, Stacksync supports a wide range of connectors, including NetSuite, HubSpot, Oracle DB, Snowflake, and BigQuery, providing a future-proof integration strategy. This eliminates vendor lock-in while enabling comprehensive operational data consistency.
Implementation and Operational Impact
Stacksync is very easy to set up and use, all done in no-code, completed in minutes with no need for specialized knowledge or expensive Salesforce consultants, providing a user-friendly interface for configuration and monitoring.
Advanced Event-Driven Capabilities: Teams can trigger services when certain events occur in Postgres or Salesforce, with complex filters like triggering events only when new leads are created with specific country and contract value criteria. There are no limits to the scenarios you can create, all in no-code, working for data creation, update and deletion on any connector.
Proven ROI and Customer Success: Stacksync is described as a better, cheaper and more enterprise-ready "Heroku Connect" with many more connectors, much more affordable and accessible to small and medium-sized businesses that might find Heroku Connect too expensive.
Workato approaches integration through an automation-first lens, offering a platform for building "recipes" that connect applications and automate workflows, best for organizations needing complex workflow automation alongside data synchronization.
Capabilities and Positioning
Workflow-Centric Architecture:
Ideal Use Cases: Organizations requiring comprehensive workflow automation beyond simple data synchronization, particularly those with diverse application ecosystems requiring process orchestration.
Limitations for Pure Data Synchronization
Workato is a powerful enterprise automation platform, but its strength lies in complex, multi-step workflow orchestration, not high-performance data synchronization. Teams prioritizing real-time data consistency over workflow automation may find more focused alternatives more effective.
Many organizations consider building custom integrations using Salesforce APIs and database connections directly.
Technical Considerations
Development Requirements:
Cost Analysis: While eliminating third-party licensing costs, custom development requires significant engineering investment. Total cost of ownership often exceeds managed solutions when factoring in development time, maintenance overhead, and opportunity costs.
When Custom Development Makes Sense
Organizations with unique data transformation requirements, specific compliance needs, or existing integration infrastructure may benefit from custom approaches. However, most teams achieve better ROI through purpose-built platforms.
