Best alternatives to Planview Enterprise One

Microsoft Project Online is offered exclusively as a cloud-based service within the Microsoft 365 ecosystem. There is no option for on-premises or self-hosted deployment, so enterprises must rely on Microsoft's cloud infrastructure for hosting and data management.

Microsoft Project Online itself requires an internet connection to access and update projects. However, users can utilize the desktop client Microsoft Project Professional, which supports offline work. Changes made offline in Project Professional can be synchronized with Project Online once reconnected.

Data stored in Microsoft Project Online remains the property of the customer organization. Microsoft acts as a data processor under strict compliance frameworks (e.g., GDPR, ISO 27001). Data is encrypted both at rest and in transit, and customers retain control over access permissions through Azure Active Directory.

Microsoft Project Online exposes REST APIs primarily through the Microsoft Graph and Project Online CSOM APIs. These APIs support project, task, and resource data operations but have throttling limits and do not cover all UI functionalities. Some complex portfolio analytics features are not accessible via API and require manual interaction or Power BI integration.

Project data can be exported from Microsoft Project Online using built-in export features to Excel or Project desktop files (.mpp). For migration, third-party tools or custom scripts leveraging the Project Online APIs are commonly used. However, complex portfolio structures and resource assignments may require manual adjustments post-migration.

Wrike is a fully cloud-based SaaS platform and does not provide self-hosting options. All data is stored on Wrike's servers with enterprise-grade security, but on-premise deployment is not supported.

Wrike requires an active internet connection for most functionality. While some mobile apps offer limited offline access to cached tasks, full offline editing and syncing are not supported.

Wrike supports exporting project data in formats like Excel and CSV, and also provides API access to extract data. However, there is no one-click full project export/import for migrating entire workflows to other tools.

Wrike's API is robust for task and project management but has rate limits and some endpoints require specific permissions tied to user roles. Bulk data operations can be slow, so careful planning is needed for large-scale integrations.

Smartsheet is a fully cloud-based SaaS platform and does not offer a self-hosted deployment option. All data and workflows reside on Smartsheet's servers, so teams requiring on-premises hosting or private cloud installations will need to consider alternative solutions.

Smartsheet does not provide native offline editing capabilities. Users must be connected to the internet to access, edit, and sync their sheets. Some limited offline viewing is possible through exported files, but real-time collaboration and automation require an active connection.

Data entered into Smartsheet remains the property of the customer, but it is stored on Smartsheet's cloud infrastructure. Users can export their sheets in formats like Excel, CSV, and PDF for backup or migration purposes. However, there is no direct database export or bulk API export for entire account data, which can complicate large-scale migrations.

The Smartsheet API provides robust REST endpoints for reading and writing sheet data, managing users, and automations. However, it has rate limits (typically 300 requests per minute) and does not support all UI features such as advanced reporting or some automation triggers. Complex relational data modeling is also limited compared to database-centric platforms.

Smartsheet supports importing data directly from Excel and CSV files, which is the primary method for migrating from Excel or Airtable exports. For Airtable, users typically export tables as CSV and then import them into Smartsheet sheets. However, complex Airtable relationships and app-like workflows may require manual reconfiguration since Smartsheet's relational modeling is less flexible.

Cerri is offered as a modern SaaS platform and does not currently provide a self-hosted deployment option. All data and project management features are accessed through their cloud service, so teams requiring on-premises hosting would need to consider alternative solutions or contact Cerri for potential enterprise arrangements.

Cerri requires an active internet connection to access its project management features since it is a cloud-native SaaS application. There is no offline mode or local client that supports offline editing or syncing at this time.

Cerri ensures that customers retain full ownership of their project data. The platform supports exporting project information in common formats such as CSV and Excel for offline backup or migration purposes. However, some export features may be limited depending on the subscription tier.

Cerri provides a RESTful API for integrations, but API access and rate limits vary by plan tier. Some advanced API features, such as webhooks and automation triggers, are only available on higher subscription levels. It is recommended to review the API documentation and plan details to ensure it meets your integration needs.

Migrating to Cerri from platforms like Smartsheet typically requires exporting project data from the legacy tool in supported formats (CSV, XLSX) and then importing it into Cerri. While Cerri offers import utilities to facilitate this process, some manual reconfiguration of workflows and permissions may be necessary due to differences in feature sets and data models.
