View project Capabilities
Clear capabilities from format coverage to production delivery.
Designed for real business systems, balancing preview quality, integration speed, deployment control and commercial licensing.
Browser-Native Deployment
Parse and render files in the browser to reduce conversion services, queues and temporary-file handling.
Private by Design
Adaptable to intranets, offline environments, private clouds and dedicated cloud deployments.
Consistent Across Frameworks
Vue, React, Svelte, jQuery, Web Components, plain Web, iframe embedding and static-site deployment are supported.
Acceptance Friendly
Online demos, document comparisons, sample matrices and real screenshots make project validation easier.
On-Demand Loading
PDF, Office, WPS, CAD, EDA, 3D and media runtimes load only when the matched file type needs them.
Continuous Improvement
Real business files drive compatibility improvements across Word, PowerPoint, Excel, PDF, OFD, CAD, archives and email.
File Viewer
Build an attachment center as one evolvable product capability.
Flyfish File Viewer now runs as a unified ecosystem: core owns the format matrix and lifecycle, while each framework package stays native and keeps options, events, search, zoom, print, export and watermark behavior consistent.
Cover the enterprise formats that are common, valuable and often hard to ship well.

What problems do Flyfish products solve?
Flyfish provides browser-native file preview, Office and WPS reading, CAD and EDA engineering views, 3D model inspection and document intelligence for OA, archives, knowledge bases, PLM, SaaS and intranet systems.
Must files be uploaded to a third-party conversion service?
Core products prioritize browser-local parsing and rendering and can run on customer-owned static sites, intranets, private clouds or offline environments. The selected product and integration path determine whether files leave the business boundary.
Which Office and engineering formats are supported?
Office Preview covers DOC, DOCX, PPT, PPTX, XLS, XLSX and XLSB. File Viewer also covers PDF, OFD, CAD, archives, email, media and code. Model Viewer targets STEP, JT, FBX, OBJ, glTF, C4D, MAX and other 3D formats.
Which frontend stacks can be integrated?
File Viewer supports plain Web, Vue, React, Svelte, jQuery, Web Components and iframe integrations, with heavy parsers, Workers, WASM and model adapters loaded only when required.
How should teams choose between public, commercial and enterprise source editions?
Public artifacts fit technical evaluation and basic integration. Commercial editions cover licensed production use. Enterprise source editions fit teams that need full source, internal maintenance, deep customization and long-term delivery assurance.
How can a technical evaluation begin?
Validate representative files in the live demos, then send target formats, frontend stack, deployment environment and sanitized samples to admin@flyfish.dev for a product and delivery recommendation.
