SpreadJS Licensing

Licensed Per Developer and Deployed Hostname
A Developer license is needed for each developer using SpreadJS. In addition, a Deployment license is needed for each separate production hostname SpreadJS is deployed on.

You can purchase both the Developer license and Deployment licenses separately. We also offer a "SpreadJS Developer License + SpreadJS One (1) Annual Hostname Deployment License Bundle" which includes one Developer license and one Annual Deployment license for internal and non-commercial deployment. Perpetual Deployment licenses are available.

Definition of License Types
At least one Developer License and one Deployment License are required to develop with and then deploy SpreadJS in your application(s).

Developer License
A Developer license is required for each separate developer developing with SpreadJS. The perpetual developer license includes:

  • One Year Maintenance which grants you access to all product updates and support.
  • Develop on localhost dev machine, for example http://localhost.
  • SpreadJS Designer App license to use the local run-time designer
  • One (1) Non-Production deployment license for testing/staging/QA environments with 90-day expiration

Deployment Hostname License
Each production server hostname(s) and/or named mobile/desktop application(s) where SpreadJS will be deployed to, is licensed separately. Annual subscription fees for Deployment licenses are required to be paid each year to continue to deploy SpreadJS in your application(s).

The pricing is determined on whether your application(s) is for Internal/Non-commercial or Commercial use and the number of deployed Hostnames.

Internal and Non-commercial use is defined as an application(s) that will be used for internal or external use where the end-user will not be charged to access the service(s).

Commercial and/or SaaS use is defined as an application(s) that will be used where the end-user or company(s) will be charged to access the service(s).

Optional Add-On Deployment Licenses
SpreadJS also offers optional add-on deployment packages that are not included in the base SpreadJS purchase. These add-ons grant you additional specialized functionality that you can offer to your users. Like SpreadJS, the add-on pricing is based off the number of Hostnames these will be deployed to. The Annual pricing varies based on Internal/Non-commercial or Commercial use.

  • DataCharts - The DataCharts add-on allows developers to bind charts directly to the Data Manager data, eliminating the need for the data to be stored directly within the SpreadJS workbook.
  • Designer Ribbon Component - The SpreadJS Designer Ribbon Component (formerly Designer Component add-on) gives developers the ability to embed this same ribbon bar and UI functionality into their own spreadsheet web applications.
  • GanttSheet - The GanttSheet gives developers the ability to embed Gantt chart functionality into their own spreadsheet web applications.
  • PivotTable - The Pivot Table gives developers the ability to embed full pivot table functionality into their own spreadsheet web applications.
  • ReportSheet - The ReportSheet gives developers the ability to allow their end users to easily create reports in their own spreadsheet web applications. A ReportSheet license now also enables the DataCharts Add-On to be used directly within ReportSheet, enabling advanced and dynamic charting capabilities.
  • AI-Assistant - Empower users to generate complex Excel formulas, explain logic, and shape PivotTables with natural language prompts. AI-driven worksheet functions also bring intelligent data processing directly into the cell.
  • Collaboration Server - Enable real-time multi-user editing in JavaScript spreadsheet applications, keeping every workbook instantly synchronized. It manages permissions, user presence, and update flow to deliver smooth, reliable team collaboration.

About Production and Non-Production Deployment Licenses
Production and Non-Production deployment licenses are named licenses for the designated server(s) unless Unlimited domain option was purchased. Non-Production licenses include a 395-day expiration date with watermark unless otherwise noted.  Non-Production license keys are only to be used for testing, staging, or similar internal QA environments and not live customer facing production sites.

Examples of Hostnames

  • A Five (5) Hostname Deployment License would properly license these five different hostname deployment scenarios: www.domain.com, www.domain.jp, domain.com, sub1.domain.com, sub2.domain.com.
  • A Single Domain License (*.domain) would license unlimited hostnames on a single top-level domain: www.domain.com, sub1.domain.com, sub2.domain.com, sub3.domain.com, etc. such as common in SaaS applications.
  • A Named Mobile/Desktop Application license would license a single application for distributed applications where the run-time hostname may be 'localhost', such as Electron or Ionic applications, or there is no defined hostname.
  • An Unlimited Domain License (*.* wildcard) would license unlimited Domains, Applications, and Hostnames including multiple SaaS scenarios.

Perpetual Deployment
Perpetual Deployment pricing options are also available. Please contact us for pricing.

  • Note for customers in Korea: Please be aware that MESCIUS Korea does not include major upgrades in maintenance for perpetual licenses in Korea. Service packs for the current version and technical support are provided. You will need to purchase an upgrade license to obtain major new versions.
