(Sustain + Open Source — focused on sustaining maintainers and ecosystems)
SustainOSS is an open-source repository health and maintainer sustainability tracker that detects burnout risk, visualizes contribution load, and recommends actionable improvements to keep FOSS projects healthy and sustainable.
It helps open-source communities maintain momentum without burning out their core contributors.
Open-source ecosystems rely heavily on a small number of core maintainers. As repositories grow:
PR and issue volume increases
Response time delays accumulate
Maintainers experience burnout
Contributor retention drops
Currently, existing repository analytics tools focus on:
Stars
Commits
Activity graphs
But none focus on human sustainability metrics such as:
Maintainer load imbalance
Burnout risk indicators
Contribution distribution fairness
Latency in issue triaging
There is no open-source tool centered around maintainer well-being and contributor equity.
SustainOSS is a fully open-source analytics platform that analyzes Git repository activity and generates:
PRs reviewed per maintainer
Open issue responsibility distribution
Average review turnaround time
Contribution concentration index (how centralized the repo is)
Maintainer handling > X% of total activity
Increasing backlog trend
Declining review responsiveness
Long untriaged issue streaks
A composite “Repo Sustainability Index” based on:
Contributor diversity
Load distribution
Response time
Retention ratio
Visual repo health dashboard
Burnout risk alerts
Suggested contributor redistribution strategies
“Good First Issue” intelligence tagging
Historical trend graphs
Open API for ecosystem integrations
Most tools (like basic repository graphs) measure output volume.
SustainOSS measures:
Human sustainability of open source projects.
It reframes repository analytics from:
“How active is this project?”
to
“Is this project sustainable for the people maintaining it?”
This shifts focus to Digital Commons longevity.
Prevents maintainer burnout
Encourages healthier contribution patterns
Helps orgs detect risk early
Supports community governance decisions
Strengthens long-term sustainability of open projects
