ExploreAbout this exam
The Certified Open Source Developer for Enterprise (CODE) is a Linux Foundation certification aimed at developers who consume, contribute to, and manage open source software inside a company context. Per the Linux Foundation, it was created with expert input from open source and OSPO experts from the Linux Foundation, OSI, the TODO Group, and FINOS communities. The exam is a 90-minute, online, proctored, multiple-choice test with no prerequisites and a stated beginner experience level; the certification is valid for two years, and exam eligibility runs 12 months with one retake included. Five domains are published: Fundamentals of Open Source Software Development (24%), Open Source Licensing and Usage Guidelines (14%), Consuming Open Source Software (28%), Contributing to Open Source (22%), and Open Source Management Operations (12%). The largest weight sits on consuming open source: codebase risk, maintenance plans, the software supply chain, dependencies, approval processes, and SBOMs. Preparation options the Linux Foundation points to include the Open Source Essentials for Developers (LFD221) course, the Open Source Management & Strategy course, the TODO Group guides, and the free LFD125 and LFC194 courses; a learning path to CODE is also listed.

What you'll study
About Certified Open Source Developer for Enterprise preparation
What is the exam format and how long do I have?
It is an online, proctored, multiple-choice exam lasting 90 minutes. The Linux Foundation lists no prerequisites and rates the experience level as beginner. Because it is proctored, expect identity verification and a locked-down browser session, so test your webcam, microphone, and connection well before your slot.
How much does CODE cost, and are there bundles?
The exam alone is $250. The Linux Foundation also lists two bundles: exam plus the THRIVE-ONE Annual Subscription at $495, and exam plus the Open Source Essentials for Developers (LFD221) course at $299. A 100% money back guarantee is advertised, and corporate quotes are offered for groups of more than ten.
How long is the certification valid, and can I retake the exam?
The online certification is valid for two years, and exam eligibility lasts 12 months and includes one retake. Plan your renewal before the two-year mark so your credential does not lapse. The Linux Foundation advises adding the badge to LinkedIn, LFX, GitHub, and other profiles once you pass.
Which domain should I study first?
Start with Consuming Open Source Software at 28%, the heaviest domain: codebase risk, maintenance plans, supply chain, dependencies, approval processes, and SBOMs. Then take Fundamentals at 24% and Contributing at 22%, which together outweigh licensing at 14% and management operations at 12%. Cover licensing early enough to inform the consumption topics.
Do I need other certifications before attempting CODE?
No. The Linux Foundation states there are no prerequisites. It separately suggests that technical depth in infrastructure, cloud, DevOps, and security helps any enterprise IT professional, naming LFCS, CKA, CKAD, and CKS as examples. Treat those as optional background rather than entry requirements for CODE.
What free or low-cost preparation does the Linux Foundation point to?
It lists a learning path to CODE, the Open Source Management & Strategy course, the TODO Group guides and resources, and two free courses: Security for Software Development Managers (LFD125) and Implementing Open Source License Compliance Management (LFC194). The LFC194 material maps closely to the licensing domain, so it is a sensible free starting point.
What is the most common way candidates lose points?
Underestimating the process questions. The exam tests how a developer integrates open source usage into company policy and interacts with the OSPO, not just license trivia. Candidates who memorize license names but cannot describe approval flows, SBOM handling, CLA and DCO mechanics, or escalation paths tend to struggle on the two heaviest domains.
Who is CODE actually designed for?
The Linux Foundation frames it for developers who consume and contribute to open source under enterprise policy, and for legacy-system professionals showing they have embraced open source. It also positions it as a step toward tech-focused business leadership and toward cybersecurity-focused roles, so it suits practitioners moving from pure coding into governance-aware work.
What topics does the licensing domain cover?
Per the published competencies: intellectual property, software licensing and open source legalities; open source and copyleft license compliance; risk assessments; export control regulations and compliance; and Contributor License Agreements (CLA) and Developer Certificate of Origins (DCO). It is only 14% of the exam, so study it for accuracy rather than depth.
