Heroku Connect is a data synchronization service that links Salesforce data with a Heroku Postgres database, creating a data replica for development, analytics, or building customer-facing applications. While powerful, a common problem emerges as data volumes grow: Heroku Connect becomes prohibitively expensive, with costs escalating into thousands of dollars per month. For businesses aiming to scale efficiently, the search for affordable Heroku Connect replacements that offer superior features without the steep price is a critical initiative.
This article explores the limitations and soaring costs of Heroku Connect and introduces modern alternatives that can reduce data synchronization expenses by up to 70%. We will cover what Heroku Connect is and what alternatives exist in the market today.
The Soaring Costs and Limitations of Heroku Connect
While Heroku Connect provides a functional bridge between Salesforce and Postgres, its value proposition diminishes when you examine the total cost of ownership and inherent technical limitations.
The Price of Syncing
Heroku Connect's pricing isn't a simple line item. Bi-directional sync capabilities are bundled into expensive starter packages, creating a significant financial barrier. For instance, the Dev Starter package begins at €4,000/month, while the Prod Starter package is a staggering €40,000/month [1]. These figures don't even include the cost of the underlying Heroku dynos required to run your application, which adds to the total monthly expense [2]. This bundled model forces companies to pay for a suite of services they may not need just to access a core sync feature.
Beyond the Price Tag: Key Limitations
The high cost is only part of the story. Technical teams often encounter several operational constraints:
- Not Truly Real-Time: On many plans, Heroku Connect polls for changes every 10 minutes. While its Accelerated Polling feature using Salesforce Change Data Capture (CDC) offers an improvement, it's still a polling-based architecture, not a true event-driven, real-time sync, and doesn't cover all use cases [3].
- Limited Error Handling: The platform lacks a granular, user-friendly dashboard for issue management. Sync failures can occur silently, leading to data drift and inconsistencies that are difficult to diagnose and resolve without manual intervention.
- Narrow Scope: Heroku Connect is purpose-built for one job: syncing Salesforce with Heroku Postgres. This is a significant limitation for any organization with a more diverse tech stack or future plans to integrate other CRMs, ERPs, or databases.
Key Features to Look for in a Heroku Connect Alternative
When evaluating replacements, it's crucial to look beyond a simple point-to-point connection. A modern data integration platform should empower your engineering teams, not just replicate data.
Here is a checklist for evaluating potential replacements:
- True Real-Time, Two-Way Sync: Look for sub-second, event-driven synchronization that propagates changes bidirectionally in milliseconds, not minutes.
- Cost-Effectiveness: The platform should offer a transparent, predictable pricing model that scales reasonably with your data volume, not one based on expensive, bundled packages.
- Scalability: It must provide the confidence to sync millions of records from day one without performance degradation or the need for constant re-architecting.
- Ease of Use: A no-code or low-code setup is essential to reduce engineering time spent on API plumbing and minimize ongoing maintenance.
- Advanced Features: The tool should offer capabilities like workflow automation, smart API rate limit management, and a robust issue management dashboard.
- Security and Compliance: It must be enterprise-ready, with support for SOC 2, GDPR, and other compliance standards, alongside secure connection options.
Finding a solution that checks these boxes is key to an affordable real-time sync that scales with your business.
Stacksync: The #1 Cost-Effective Heroku Connect Replacement
Stacksync is a modern data sync and workflow automation platform engineered to address the cost and performance shortcomings of legacy tools like Heroku Connect. It provides true real-time, bi-directional synchronization between CRMs, ERPs, and databases. For companies feeling constrained by Heroku Connect, Stacksync is more than just an alternative; it's a strategic upgrade and a great alternative to Heroku Connect that offers more flexibility and power.
How Stacksync Delivers 70% Cost Savings
Stacksync’s efficient, usage-based pricing model stands in stark contrast to Heroku's expensive bundled packages. Instead of paying a massive flat fee, you pay for the records you actually sync, with costs decreasing at scale. This transparency and predictability can lead to significant savings. Many organizations find they can cut cloud costs substantially by making the switch [4].
Consider a hypothetical scenario for a company syncing 1 million records:
| Feature / Metric |
Heroku Connect (Prod Starter) |
Stacksync (Pro Plan) |
| Base Plan Cost |
€40,000/month |
$3,000/month |
| Records in Sync |

1 Million Included |
| Primary Use |
Salesforce <> Heroku Postgres |
Any 3 Systems (e.g., SFDC, Postgres, NetSuite) |
| Real-Time Sync |
Polling-based (minutes) |
Event-driven (milliseconds) |
| Potential Savings |
— |
>90% |
Key Takeaways
Stacksync delivers real-time, event-driven synchronization across multiple systems at a fraction of the cost — offering >90% savings compared to Heroku Connect’s enterprise pricing.
Heroku Connect is limited to Salesforce ↔ Postgres sync and relies on polling, leading to latency and higher monthly expenses.
For organizations scaling integrations beyond Salesforce, Stacksync provides a faster, more flexible, and cost-efficient alternative.
Note: This is an illustrative comparison. Exact savings depend on your specific plan and data volume.
Feature-by-Feature Comparison: Stacksync vs. Heroku Connect
The differences go far beyond price. A direct feature comparison reveals why modern platforms are superior Heroku Connect alternatives with better pricing [5] [1].

Key Takeaways
Stacksync provides sub-second, event-driven synchronization across 200+ systems, complete with two-way sync, workflow automation, and proactive issue management — all in one managed platform.
Heroku Connect is limited to Salesforce ↔ Postgres syncing, using polling intervals that delay data updates and increase operational costs.
For companies seeking real-time scalability without the Heroku overhead, Stacksync offers faster performance, broader integrations, and predictable pricing.
