HubSpot CRM vs Microsoft Dynamics 365: Which Alternative is Best? (2026)

HubSpot CRM is strictly a cloud-based platform and does not offer a self-hosted version. All data and services are managed on HubSpot's servers, so on-premises deployment is not supported.

HubSpot CRM does not offer offline functionality. Users need an active internet connection to access and update CRM data, as it is a cloud-native application without offline sync capabilities.

Data entered into HubSpot CRM remains the customer's property. HubSpot provides export tools allowing users to download contacts, deals, and other CRM data in CSV format for migration or backup purposes.

HubSpot CRM's API is robust but has rate limits and some endpoints do not support all CRM objects or custom properties. Additionally, advanced customization via API is more limited compared to platforms like Salesforce, which can affect complex integrations.

Migrating away from HubSpot CRM is generally straightforward for standard data like contacts, companies, deals, and tickets via CSV exports. However, complex workflows, custom properties, and marketing automation setups may require manual reconstruction in the new system.

Microsoft Dynamics 365 is primarily offered as a cloud service hosted on Microsoft Azure. While there are on-premises versions of Dynamics CRM (like Dynamics 365 Customer Engagement on-premises), the full Dynamics 365 suite with ERP and other modules is designed for cloud deployment. Self-hosting the entire Dynamics 365 suite is not supported, and customers looking for private cloud deployments typically use Azure with dedicated resources and network isolation rather than fully self-hosting.

Dynamics 365 offers offline capabilities primarily through its mobile apps and the Dynamics 365 Customer Engagement on-premises client. Offline data synchronization allows users to continue working without connectivity and sync changes once reconnected. However, offline functionality is limited in scope and mainly targets field sales or service scenarios; full offline use of all modules, especially ERP components, is not supported.

Customers retain full ownership of their data stored in Microsoft Dynamics 365. Microsoft acts as a data processor and complies with major privacy regulations such as GDPR and HIPAA. Data residency options are available depending on the Azure region selected. Microsoft provides detailed compliance documentation and tools for data export, audit logs, and data deletion to ensure customer control over their data.

Microsoft Dynamics 365 exposes extensive RESTful Web APIs and OData endpoints for integration. However, API usage is subject to throttling limits based on user licenses and service plans, which can impact high-volume integrations. Some complex ERP modules have limited API coverage compared to CRM modules. Additionally, certain customizations require use of the Power Platform connectors or Azure Logic Apps for advanced workflows beyond direct API calls.

Microsoft provides data migration tools such as the Dynamics 365 Data Import Wizard and the Data Migration Framework, which support common legacy CRM platforms like Dynamics CRM 2016, Salesforce, and others. For large or complex migrations, Microsoft recommends using Azure Data Factory or third-party ETL tools to transform and load data. Exporting data from Dynamics 365 is supported via Data Export Service to Azure SQL or using Power Platform Dataflows, enabling integration with external reporting or backup solutions.
