‍for broken syncs

Bi-directional sync with delays. Supports two-way Salesforce–Postgres sync but relies on scheduled polling (every ~10 minutes by default, configurable to ~2 minutes on paid plans).

True real-time, two-way syncwith sub-second latency. Changes in one system propagate instantly to others, keeping data consistently up-to-date across all connected platforms.

Single-use connector (Salesforce ↔ Postgres only). Designed exclusively for Salesforce data integration, it syncs a Salesforce org with a Postgres database and does not connect to other databases or SaaS applications. There is no multi-source or multi-app connectivity beyond this scope.

Extensive integration library with 200+ pre-built connectors for databases, SaaS apps, CRMs, ERP systems, and more. This broad connector ecosystem enables unified data sync across virtually all your tools out-of-the-box.

Heroku-only Postgres requirement. Tightly coupled to Heroku’s ecosystem, it synchronizes Salesforce data only with a Heroku Postgres database. The sync service must run in the Heroku environment (co-located with your app), so external or self-hosted Postgres instances aren’t supported.

Flexible Postgres support – connect to any PostgreSQL database (cloud-hosted, on-premises, or managed) without vendor lock-in. Stacksync works with your existing Postgres infrastructure, wherever it lives.

Basic monitoring tools. Includes a built-in web dashboard to configure and monitor the Salesforce-Postgres connectionand offers logs for troubleshooting. These tools cover the single sync pipeline well, but lack advanced cross-system monitoring or custom alerting beyond Heroku’s standard logging and notifications.

Full visibility via real-time monitoring dashboards, configurable alerts, and detailed log explorers. Stacksync provides comprehensive insight into sync status and performance, allowing proactive issue resolution and governance.

Scales with conditions. Capable of syncing large Salesforce datasets (even hundreds of millions of records per object) by leveraging Bulk APIs for efficiency. However, achieving high throughput requires proper provisioning (e.g. using larger Heroku Postgres tiers for better I/O and more connections). Very large or multiple org scenarios may need complex setups (like multiple Heroku Connect add-ons) to maintain performance.

Enterprise-scale performance – designed to handle everything from small data sets to millions of records seamlessly. Stacksync’s cloud-native architecture scales with throughput, maintaining high sync performance as data volumes grow and workloads increase.

Data sync only – no workflow engine. Heroku Connect provides pure data integration (objects and tables only) and does not natively handle business process automation. Any additional actions or logic (e.g. sending notifications, updating other systems) must be implemented outside the platform (in Salesforce via Apex/Flow or in your Heroku app’s code), since the service itself doesn’t orchestrate workflows.

Built-in automation engine to trigger actions on data changes. Stacksync can execute multi-step workflows, integrate with APIs, or run custom logic in response to sync events – all configured with no-code/low-code tools. This empowers you to automate business processes around your data syncs without custom development.

Trusted Salesforce platform security. Runs on Heroku’s secure infrastructure, using SSL encryption for all data transfer between Salesforce and the database. No customer data is stored on the add-on itself beyond the synced Postgres (any transient processing is on encrypted volumes). For regulated data, a Shield Connect edition is available to meet HIPAA and other high-compliance requirements, leveraging Heroku Shield’s audited environment.

Enterprise-grade security at every layer. All data is encrypted in transit and at rest, with strict role-based access controls and support for SSO/MFA. Stacksync is compliant with SOC 2, GDPR, HIPAA, and other standards, and it retains no persistent data on the platform – ensuring your sensitive information flows through securely without being stored.

Enterprise pricing model. Beyond a free demo tier (limited to 10,000 synchronized rows), Heroku Connect requires an Enterprise contract for production use. Pricing is not publicly listed (it’s negotiated), and can be significant – often running in the thousands of dollars per month for organizations syncing large volumes of Salesforce data.

Cost-effective and transparent. Offers predictable subscription plans that scale with usage, often at a lower total cost than legacy solutions. Stacksync’s pricing is straightforward (with tiered packages and usage-based components), helping avoid the steep expenses of custom builds or limited proprietary tools.
