Docxtemplater vs Legito

Docxtemplater is a JavaScript library that generates Word, PowerPoint, Excel, and OpenDocument files by filling templates with JSON data. Users add tags such as {user} to a Word or PowerPoint template, and the engine replaces them with supplied values. The core library is open source under MIT/GPLv3 and includes basic templating; advanced features are available through paid modules sold individually, in a four-module PRO pack, or through ENTERPRISE. The library is tested with active Node.js versions 12 through 24 and common browsers. Its Docker API accepts a template and JSON data over HTTP and produces DOCX, PPTX, or XLSX files. The ENTERPRISE Docker image supports use from several programming languages, while code integration uses JavaScript with examples for common frameworks. Generation runs locally without outbound network requests; on-premise deployment and air-gapped environments are supported with the APPLIANCE license. Developers configure the library, while office users can create templates with their existing document skills. Paid plans start at €500 a year. Rendering DOCX page layout and page breaks is outside its scope.

Legito is a document lifecycle service for automating, managing, approving, and signing documents. Users can build advanced documents without coding by combining interactive templates with inserted data, then configure workflows and approvals. Listed document tools include renewal tracking, revision history, external recordkeeping, analytics, and managerial reporting. Signatories can use the service in a web browser on any device without installing an app; BioSign supports biometric signing of PDF documents on tablets and smartphones. Direct signing is limited to PDFs, while other document formats are converted to PDF. Legito says signed PDFs use a verified third-party certificate for encryption and provides audit trails and timelines that record actions and timing. Integration options include off-the-shelf, no-code, API, webhook, and DocuSign connections. The free tier includes a workspace and electronic signatures. Paid Workspace plans have a 30-day trial. Listed Starter pricing is €6.90 a month, and Business is €13.90 a month. Membership renews automatically, but cancellation carries no extra cost. Legito was founded in 2014.
