Who is Flynet?
Flynet is a software company that provides web-based terminal emulation, modernization, and integration tools for organizations using legacy mainframe and midrange systems.
- Web terminal emulation solutions for accessing mainframe and midrange host applications via browsers.
- Legacy application modernization tools for creating web and mobile interfaces over existing host systems.
- Integration platforms for exposing host transactions as web services and APIs (integration middleware).
- Development tooling for model-driven generation of web applications from green-screen interfaces.
- Professional services for assessment, implementation, and customization of host access and modernization projects.

More About
Flynet focuses on software and services that enable enterprises to maintain and extend existing mainframe and midrange investments while providing modern user and integration interfaces. Its products are typically deployed in environments where host systems remain core for transactional processing, but business stakeholders require browser-based access, API-level integration, and alignment with contemporary web architectures. This places Flynet within the host access, terminal emulation, and legacy modernization categories commonly used in enterprise IT portfolios.
The company’s web terminal emulation offerings provide 3270, 5250, and similar host protocol support delivered via standard web browsers, often without requiring local client installation. Architecturally, these solutions sit between the user and the host, translating browser requests into host terminal sessions using protocols such as TN3270 or TN5250. This design fits into secure network topologies where centralized deployment, authentication, and access control are managed through existing enterprise directories and security frameworks.
Flynet’s modernization and integration tools are built to surface legacy transactions as web-based workflows or as service endpoints, such as Simple Object Access Protocol (SOAP) or REST-style APIs (application integration). Development often follows a model-driven approach: host screens are analyzed and mapped, then used to auto-generate web forms, service interfaces, and business objects. This reduces direct dependency on terminal emulation at the presentation layer while preserving the underlying COBOL or host-based business logic.
In comparison to traditional thick-client terminal emulators, Flynet’s browser-first approach supports centralized administration and easier deployment across distributed workforces. For enterprises that might otherwise consider rewriting or replacing host applications, Flynet’s tooling offers an integration- and interface-layer alternative by wrapping existing systems and exposing them to web, mobile, and service-oriented architectures. This aligns with common modernization patterns such as screen wrapping, service enablement, and staged migration.
From a directory and taxonomy perspective, Flynet maps to several enterprise solution categories: host access and terminal emulation, legacy application modernization, application integration middleware, and related professional services. Its technology is typically evaluated alongside other host access platforms, API-enablement tools for mainframe and midrange systems, and low-code or model-based modernization offerings used by financial services, government, manufacturing, and other sectors that rely on established transactional hosts.
