NEVER-ENDING SUPPORT FOR
Apache Grails
Long-term security for Grails 6.2 & 7. Delay updates until you are ready, safely.
HeroDevs NES for Apache Grails delivers ongoing security updates for Grails 6.2 & 7, ensuring compliance without the need for costly application rewrites.
What’s the future of Grails with the upcoming Spring Boot 3.5 EOL?
Apache Grails 6.x has been out of Support since October 2025 and depends on deprecated Spring Boot 2.7.
Apache Grails 7.x is still in support but depends on a soon-to-be end of life Spring Boot 3.5, which has an End of Life date in June 2026.
Grails 8 has yet to be released, but is planned to be built on Spring Boot 4.x. The window of time for release and lapse in support is nearing.
If you are still using your Grails 6.x or 7.x reliant on EOL or soon-to-be-EOL versions of Spring Boot, what is your plan? Time is running out.

Learn more.The Problem We Solve
Grails is entrenched in large enterprise and mid-market organizations with mature, multi-year application investments, but the framework faces predictable End of Life (EOL) cliffs.
The EOL Cliff
Grails 6.2.x reached EOL on October 19, 2025, and Grails 7 is built on Spring Boot 3.5, which is scheduled to go EOL on June 30, 2026
Exposure
This rapid EOL of underlying Spring Boot dependencies exposes you to unpatched CVEs in Spring Boot, creating potential alerts for your security teams
Costly Migration Risk
Migration away from Grails introduces high engineering costs, multi-quarter timelines, and potential application breakage, while rewrites can be significantly more than the price of NES
HeroDevs addresses this risk by providing security updates delivered by experts, allowing you to maintain compliance and security.

Frequently Asked Questions
Below are common questions our customers have. Of course, we’re happy to meet with you and answer these and other questions you might have.
What is the ROI of NES for Apache Grails?
NES for Grails saves customers internal engineering hours, migration acceleration costs, and audit remediation costs. The investment typically pays for itself with just one avoided CVE incident or more time to work through development cycles on existing technology.
Can we just fork Grails internally and patch it ourselves?
While technically possible, backporting CVEs is expensive and creates long-term technical debt that must be constantly maintained. Keeping track of the myriad of required dependencies in the Spring ecosystem is complex and risky. Additionally, auditors may not accept internal patches which can create compliant risk. NES provides ongoing, vendor-backed patches and documentation without internal engineering cost.
Why not just migrate to Spring Boot or another modern framework?
Migration is a long-term strategy, typically requiring quarters or years of work. NES for Apache Grails provides a secure, compliant path while you plan your migration on your own timeline, acting as a needs-based timely security solution.
