GnuCOBOL - SuperBOL

What is GnuCOBOL?

GnuCOBOL is the only truly open-source COBOL compiler that allows you to redeploy all your COBOL applications in any environment (Cloud, Linux, Windows, legacy systems). Actively developed and used since 2002, GnuCOBOL supports major COBOL dialects (IBM, MF, GCOS, etc.), enabling smoother modernizations.

Thanks to GnuCOBOL,

Reduce your costs

Eliminate proprietary licensing costs and excessive maintenance fees.

Modernize your development (DevOps)

Adopt modern DevOps practices: CI/CD, version control, automation.

Gain reliability, security, elasticity, and agility

Deploy to the Cloud, adapt quickly to business changes.

Mitigate your risks by regaining independence

Escape vendor lock-in and maintain control of your legacy assets.

Whatever your objectives may be

COBOL Preservation

Preserve your COBOL assets while adapting them to modern requirements. GnuCOBOL enables you to migrate your applications to the Cloud, integrate them with recent technologies (AI, microservices), and benefit from an open and sustainable ecosystem.

COBOL Migration

Use GnuCOBOL as a strategic transition step. Break free from mainframe dependency, test your applications in modern environments, and prepare gradual and secure migrations to other languages while maintaining business continuity.

Why Open Source?

The acquisition of COBOL-IT by Micro Focus is quite similar to VMware’s acquisition by Broadcom, with well-known consequences. This demonstrates that commercial open source poses the same strategic and financial risks as proprietary software. On the contrary, GnuCOBOL’s community-driven open source guarantees independence from a single technology provider. The SuperBOL project follows the same philosophy, staying true to OCamlPro’s DNA.

GnuCOBOL is an open-source compiler first released in 2002 under the name OpenCOBOL. Between 2013 and 2015, it was accepted as a GNU Project.

Portable

Works on all systems, from legacy to modern ones.

Dialect-agnostic

Enables migration without code modification.

Reliable

Used in production by the most demanding companies.
