I got an error like "EOL/Obsolete Software: Next.js 12.3.5 Detected." What can I do?

This means your application is running Next.js 12.3.5, which has reached end-of-life and no longer receives security updates. NES for Next.js provides a drop-in replacement to keep your application secure, compliant, and fully supported. Talk to our sales team to explore your options.

Does HeroDevs have an SLA for NES for Next.js?

Yes. Our response times vary based on the severity of the issue. Security-related and application-breaking issues are our top priority and will be resolved immediately (same day if possible). We can provide our SLA for your team to review upon request.

What Next.js versions does NES support?

NES for Next.js supports version 12.3.5. We provide ongoing support and patches to keep your applications secure and operational.

Does NES for Next.js help with compliance?

NES for Next.js helps maintain compliance by providing security patches and updates, even for older versions. Our enterprise-grade SLA stands up to HIPAA, SOC-2, PCI DSS, etc., and ensures your compliance with these standards.

Why do I need NES for Next.js?

Using an unsupported version of Next.js exposes your applications to security vulnerabilities and compliance risks. Upgrading to the latest version can be costly and time-consuming. NES allows you to stay on your current version and remain supported until you are ready to upgrade.

How does licensing work?

When you purchase Never-Ending Support, you acquire a commercial license for the support services. Our pricing model is based on the number of users who will be committing code to the project repo. Users are unnamed and transferable across team members.

What are the benefits of using NES for Next.js?

NES for Next.js offers continual security updates for EOL versions, compliance assurance (SOC2, HIPAA, PCI DSS), application stability without forced upgrades, drop-in replacement installation, and expert technical support—allowing businesses to maintain and secure legacy systems without disruption.

What happens if we do nothing now that some versions of Next.js are end-of-life?

Without security patches, your Next.js applications become increasingly vulnerable to exploits and compliance failures. Continuing to use unsupported versions increases the risk of breaches, instability, and regulatory non-compliance.

How does NES for Next.js compare to rebuilding with modern versions?

Rebuilding with modern Next.js versions can cost 4–8x more than NES, take 6–12 months of dev time, and cause operational disruption. NES secures your app now and gives you time to upgrade strategically.

How hard is it to switch to NES for Next.js?

Switching to NES is seamless. Just update your build dependencies to point to HeroDevs' private repository. No breaking changes or major refactoring needed.

React currently backports security fixes to older versions. NES for React is being considered—contact us if you’re interested in the SLA and compliance benefits.

What happens now that some versions of Next.js are end-of-life?

Your application will no longer receive security patches or updates, increasing the risk of vulnerabilities, compliance issues, and performance degradation. NES eliminates those risks without requiring immediate migration.

Can I get Next.js security patches anywhere else?

No. Once Next.js versions reach EOL, the community stops providing updates. HeroDevs’ NES for Next.js is the only commercial support offering that delivers continued security patches, compliance assurance, and expert support.

How are Next.js CVEs addressed in EOL versions? What is Next.js' official EOL policy?

Next.js EOL versions no longer receive official updates, leaving CVEs unpatched. The community lacks a clearly defined EOL policy, but major releases tend to mark the prior versions EOL. NES for Next.js fills this gap by continuously patching vulnerabilities in deprecated versions like 12.3.5.
