Why the 18% Drop in Actively Maintained Open-Source Projects Should Matter to Development Managers
Why the 18% drop in actively maintained open-source projects matters now.
This decline, reported by Sonatype, means fewer projects get regular updates, security patches, and active maintainer attention—so teams must treat third-party components as living liabilities, not free miracles. Is your team ready to manage that risk?
Key Takeaways:
- 18% decline in actively maintained open-source projects, per Sonatype's 2023 report.
- Active maintenance affects security, stability, and supply-chain health.
- Development managers must invest in SCA, SBOMs, and maintainer support strategies.
- Practical steps include dependency audits, funding critical repos, and clear upgrade policies.
What is active open-source maintenance?
Short definition first.
Active maintenance means contributors regularly update code, respond to issues, and release fixes, which keeps packages safe, functional, and compatible with modern systems—when maintainers stop updating, those packages age, accumulate vulnerabilities, and become brittle under new dependency versions.
Who keeps software healthy?
Active maintenance is the day-to-day care that projects receive from maintainers, contributors, and sponsors—this includes triaging issues, merging pull requests, updating CI, fixing security alerts, and publishing new releases, and it's the difference between a dependable library and a ticking time bomb.
I remember a time when a tiny open-source utility I trusted suddenly went quiet.
I depended on that package at a previous employer, and when a transitive dependency got a CVE we had to scramble to patch around it, because the project had no recent commits and no one answering issues.
That's the practical meaning of actively maintained.
Who counts as a maintainer?
Short answer: the humans who write and review patches.
These are the people who own the repo, approve changes, shepherd releases, update docs, and keep CI green—sometimes a volunteer, sometimes a company-funded engineer, and sometimes a single person juggling real life and unpaid work.
Why does this matter to managers?
Because your product depends on that human's time, and your risk policy should treat that dependency like any other third-party vendor relationship.
Core Benefits and Importance
Security is the first obvious point.
Actively maintained packages receive security fixes faster, have known commit histories, and often a clearer path to getting CVEs resolved—this reduces your exposure window, lowers the chance of forced hotfixes, and keeps your SCA signals cleaner.
Can you afford to wait?
Reliability follows closely behind.
If a package receives regular releases, versioning is predictable, API changes are communicated, and semantic versioning tends to be respected, which makes upgrades less painful—I've run puppeted upgrade weekends where every dependency behaved and I slept that night.
Worth the peace of mind?
Ecosystem health is the third pillar.
Active maintenance means contributors are visible, documentation is current, and integration with package registries like npm, PyPI, and Maven is maintained—this keeps your CI/CD stable and your deploys less surprising.
Do your pipelines need surprises?
Financial and operational stewardship matters too.
There is a moral angle here—funding critical open-source is a practical form of stewardship, because teams benefit from shared code and have a duty to keep it healthy, which aligns with a Catholic sense of caring for common goods and the dignity of work.
Should your budget reflect that duty?
Developer productivity gains are tangible.
When dependencies are active, developers waste less time working around bugs, and teams can focus on product features instead of firefighting third-party issues—I've seen engineering velocity climb simply by removing one flaky transitive dependency.
Is that worth a few hours of planning?
Step-by-Step Implementation Guide for Development Managers
Start with inventory in hand.
Create a complete list of direct and transitive dependencies, generate a SBOM, and run an SCA scan to prioritize risk, because you cannot protect what you do not measure—this includes tracking package sources, maintainer activity, and known CVEs.
Ready to look at facts?
- Audit dependencies quarterly.
Short checklist item—do it regularly.
Use automated tools to flag packages without commits in the last 12 months, packages with unresolved security advisories, and packages that show a declining contributor count; treat those as elevated risk.
- Classify risk and set policies.
Make a clear policy for what to do when a package is unmaintained or has high-severity CVEs—options include forking and maintaining internally, hiring the maintainer, replacing the library, or sandboxing the dependency behind stricter controls.
Which option fits your team?
- Protect the supply chain.
Implement SCA in CI, enforce signed commits or artifact signatures where possible, pin versions for production builds, and publish SBOMs for releases, because these practices reduce surprise and speed incident response.
Do you have SBOMs yet?
- Invest in maintenance where it matters.
Consider sponsoring high-value projects, offering paid time to contributors, or funding bug bounties; I've signed corporate contribution agreements and seen a small monthly sponsor plan produce a steady stream of security fixes.
Is your company giving back at all?
- Plan for upgrades.
Schedule regular dependency update sprints, define a policy for minor vs major version upgrades, and use feature flags or canary deployments when introducing risky changes; this reduces emergency patches.
Do you schedule upgrades or only react?
- Monitor and respond.
Use tooling to watch for new CVEs, abandoned maintainers, and sudden shifts in download or contributor patterns—establish an incident runbook that includes dependency remediation steps and rollback plans.
Is your team ready for a supply-chain incident?
Comparison Table

Common Mistakes to Avoid
Short warning first.
Managers often assume open-source is perpetually free and always maintained, which is incorrect and costly—I've sat in emergency meetings where an abandoned transitive dependency triggered a cascade of patches across multiple teams.
Is your plan based on wishful thinking?
Mistake 1: Blind trust in popularity.
Using download counts as a proxy for maintenance is misleading, because a package can be widely used yet barely maintained—popularity does not equal current maintainer activity, and popularity alone won't get CVEs fixed.
Do you check commit history?
Mistake 2: Ignoring transitive dependencies.
Teams often audit only direct dependencies, and then get surprised when a deep transitive package has a critical vulnerability—SCA tools can show the complete tree, and you should act on that data.
Why skip the deep tree?
Mistake 3: No backstop plan.
Assuming you'll replace a package quickly is naive—replacements can require API changes, refactoring, and QA time, so always have a fallback strategy, a fork plan, or vendor alternatives lined up.
Can you refactor overnight?
Mistake 4: Not contributing back.
Companies take code but don't contribute fixes or funding, which leaves important projects vulnerable; I once worked on a team that promised a PR and never followed through, and the project's issues sat unresolved for months.
Are you part of the problem?
Mistake 5: Over-reliance on manual checks.
Manual audits are slow and error-prone—automate SCA, CI checks, and SBOM generation to maintain scale.
Is your process mostly manual?
Frequently Asked Questions
Short header.
Below are common questions I see from managers who must balance feature velocity with supply-chain risk.
Q1: How do you tell if a project is no longer actively maintained?
Check the repo for recent commits, open issue response times, recent releases, CI status, and contributor activity—also look at the maintainer's presence on forums and package registries.
Is there a single metric?
A1: No single metric suffices, but a combination of last commit date, unresolved security advisories, and low contributor count is a reliable indicator.
Q2: Should we always replace unmaintained packages?
Not always—you can fork and maintain internally, isolate the dependency, or sponsor the original project; cost, risk, and long-term plans determine the right path.
What's cheaper in the long run?
A2: Sponsoring or contributing fixes can be cheaper than long-term maintenance by your own team, especially for widely used components.
Q3: What tools help track maintenance status at scale?
Use SCA tools like Snyk, OSS Index, or GitHub Dependabot, generate and publish SBOMs, and integrate alerts into your incident response tooling—these combined give visibility and speed.
Are tools enough?
A3: Tools are necessary but insufficient; you still need policies, budgets for sponsor programs, and people who make decisions.
Q4: How does the 18% decline change prioritization?
It raises the baseline risk for all teams using third-party code and means managers should increase investment in audits, sponsor programs, and replacement planning—treat important dependencies like vendor contracts.
Do you have plans to act?
Final Thought
Active care for open-source is not charity; it's prudent stewardship of shared resources and staff time, and it's part of honoring the dignity of work—small investments in maintenance protect many users.
I spent years watching teams take the cheap route and pay more later, so here's my blunt advice: measure your dependencies, fund the few that matter, and bake SCA and SBOMs into your CI pipeline.
That's how you treat other people's labor with respect and keep your product stable.
