Decline in Actively Maintained Open-Source Projects: What Development Managers Must Do
Open-source maintenance is shrinking. Sonatype reports an 18% drop in projects considered actively maintained in 2023, and that puts procurement, security, and platform teams on notice because more dependencies will age without caretakers, raising risk and cost. This matters now.
Key Takeaways
- 18% drop in actively maintained OSS in 2023 (Sonatype report).
- Development managers must shift focus to supplier strategy, tool choices, and stewardship of dependencies.
- Practical steps: audit dependencies, prioritize supported projects, contract support, and implement governance.
What is the decline in actively maintained open-source projects?
Open-source maintenance means people regularly update, merge PRs, and patch bugs. Sonatype's 2023 report shows an 18% decline in projects that meet 'actively maintained' criteria, which signals fewer projects with recent commits, no prompt responses to issues, and a rising share of projects that are effectively abandoned or stalled; teams that depend on those projects will see slower fixes and larger security windows if they keep relying on them. That is risky.
Maintainers are volunteers or paid engineers who spend time reviewing code, responding to issues, and releasing fixes, and when those people move on the codebase often sits. When a project stops receiving attention the risk is practical: unpatched vulnerabilities, incompatible new platform releases, and stalled feature needs—so a simple dependency update can cascade into build failures and emergency work. I've been there.
At one company I led a migration because a small, popular library stopped releasing and security scanners began flagging deep transitive dependencies; the team had to either maintain a fork or replace the component completely, and that cost more than six engineering-weeks. These events teach a clear lesson: your procurement and architecture decisions must include maintenance signals, not just popularity metrics or license checks. Plan accordingly.
Core Benefits/Importance
Actively maintained projects reduce long-term cost of ownership. When a project has regular releases, active contributors, and visible triage, it becomes less likely your team will be surprised by a critical security flaw that needs an emergency patch; proactive maintenance means predictable timelines, fewer firefights, and easier budgeting for support or sponsorship. This saves time.
For managers the benefits are practical: lower incident rates, easier audits, and clearer procurement justifications, because auditors and legal teams like measurable signals such as time-to-patch and contributor counts. From a people perspective, every time engineering is pulled into a third-party maintenance task it steals hours from product work and erodes morale, and stewardship of dependencies respects engineers' time and capabilities. Be mindful.
There's also a reputational benefit; teams that sponsor or contribute to their critical dependencies build relationships that yield faster fixes and better roadmap alignment, and this is a small, often-overlooked form of vendor management. When I was at Microsoft we used sponsorship and advisory relationships to get upstream fixes faster than simply waiting for a volunteer to find time, and the ROI was measurable in fewer production incidents. Relationships matter.
Step-by-Step Implementation/Guide
Start with a dependency audit. Run a light-weight inventory across your codebases, collect dependencies, and generate simple activity metrics: last commit date, release cadence, number of contributors, and recent security advisories, then rank libraries by criticality to your product and exposure to users. Begin now.
Define acceptance criteria. Create a policy that states what qualifies as acceptable for production use—examples: a release in the last 12 months, at least three active contributors, a documented roadmap, and responsiveness on security issues—and publish this to teams so engineers make consistent decisions. Be rigid at first.
Create fallback plans for critical dependencies. For each critical library that doesn't meet criteria choose one of a handful of paths: replace with a maintained alternative, sponsor the project, contract a vendor for support, or fork with a maintenance commitment from your team, and record the chosen path in a risk register with timelines and owners. Pick a path.
Automate governance. Use software composition analysis (SCA) tools to flag deprecated or unmaintained projects at PR time, add policy gates into CI, and set up dashboards that alert platform teams when a dependency crosses a risk threshold—this reduces manual policing and scales as you grow. Automate where possible.
Measure outcomes monthly. Track metrics such as mean time to patch, percentage of critical dependencies supported, and number of sponsored projects, and use those numbers in stakeholder reporting so procurement and security teams understand the trade-offs. Report regularly.
Make ethical choices part of policy. Consider the dignity of contributors: compensate or credit maintainers when your company benefits materially from their work, and use sponsorships to sustain ecosystems rather than extract from them; this aligns with stewardship values and reduces long-term exposure. Be fair.
Comparison Table
The table below compares **actively maintained OSS** with **unmaintained/abandoned OSS**, using the 2023 data point.
| Metric | **Actively Maintained OSS** | **Unmaintained/Abandoned OSS (Competitor)** |
|---|---:|---:|
| 2023 trend | Stable to falling, -18% overall | Increasing share, more risk |
| Security patching | Regular patches, known response windows | Infrequent or none |
| Community support | Multiple active contributors, PRs processed | Few or zero active contributors |
| Adoption risk | Lower, easier to justify in procurement | Higher, needs mitigation |
| Cost of ownership | Lower over time with stewardship | Higher due to forks and internal maintenance |
Common Mistakes to Avoid
Don't confuse popularity with maintenance. Millions of downloads can hide single-maintainer projects and that single person may disappear overnight, creating a critical failure point that popularity metrics won't reveal; star counts and download stats are noisy signals, so use activity and contributor metrics instead. Watch for single points of failure.
Don't depend on automation alone. Tools that flag vulnerabilities or outdated packages are necessary but not sufficient, because they can't decide whether to sponsor a project, contract support, or replace a library—management needs policy and budget to act on the alerts. Human decisions matter.
Don't ignore legal and license posture. Some projects lack contributor agreements or have ambiguous licensing, and treating every dependency the same exposes you to compliance risk; involve legal early and maintain an approved list of licenses and acceptable exceptions. Check licenses.
Don't assume the community will always care. Open-source contributors have limited time and competing obligations, and your team should avoid the entitlement mindset that expects unpaid maintainers to treat your company as a top priority; ethical stewardship means offering support when you benefit from their work. Be respectful.
Frequently Asked Questions
Q: How do I measure whether a project is actively maintained? A: Use simple activity metrics: recent commits, release cadence, number of contributors, issue response times, and whether there are recent security advisories; tools automate these signals and provide dashboards for managers to review. Start with those signals.
Q: Should I replace unmaintained dependencies immediately? A: Not necessarily; prioritize by criticality. For critical pieces replace, sponsor, or contract support first; for low-risk libs you can plan phased replacements or watch for abandoned status while maintaining budgeted contingency. Prioritize ruthlessly.
Q: What tools help detect unmaintained projects? A: Use SCA tools like those from major vendors, repository activity monitors, and custom scripts that track commit activity; combine signals to reduce false positives. Combine tools and judgment.
Q: How should procurement respond? A: Procurement should require maintenance criteria in vendor evaluations, include support budgets for critical OSS, and create contracts that allow for sponsored maintenance or commercial support as contingency options. Procurement must act.
Final Thought
This is about stewardship, not fear. Companies that treat open-source dependencies as strategic suppliers rather than background freebies protect users, respect contributors, and reduce unexpected costs; that's faithful stewardship of resources and time, and it aligns with a responsibility to serve the common good. Act now.
I saw the consequences of neglect at startups and the benefits of sponsorship at large firms, and the pattern is clear: active governance beats crisis firefighting. Make the choice to fund, sponsor, or replace critical projects, assign owners, and measure progress so your teams can focus on building rather than maintaining other people's neglected code. Do the right thing.
