SustainOSS: Open Source “Maintainer Load Tracker”

Problem Statement

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.

Proposed Solution

SustainOSS is a fully open-source analytics platform that analyzes Git repository activity and generates:

1️⃣ Maintainer Load Metrics

• PRs reviewed per maintainer

• Open issue responsibility distribution

• Average review turnaround time

• Contribution concentration index (how centralized the repo is)

2️⃣ Burnout Risk Indicators

• Maintainer handling > X% of total activity

• Increasing backlog trend

• Declining review responsiveness

• Long untriaged issue streaks

3️⃣ Sustainability Score

A composite “Repo Sustainability Index” based on:

• Contributor diversity

• Load distribution

• Response time

• Retention ratio

Key Features

• 📊 Visual repo health dashboard

• 🔥 Burnout risk alerts

• 🤝 Suggested contributor redistribution strategies

• 🧭 “Good First Issue” intelligence tagging

• 📈 Historical trend graphs

• 🗂 Open API for ecosystem integrations

Innovation

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.

Impact on the FOSS Ecosystem

• Prevents maintainer burnout

• Encourages healthier contribution patterns

• Helps orgs detect risk early

• Supports community governance decisions

• Strengthens long-term sustainability of open projects

This directly aligns with the spirit of FOSS Hack:

Supporting meaningful contributions to Free and Open Source software.

Technical Overview

• Git repository data ingestion layer

• Analytics engine for load computation

• Trend detection algorithms

• Sustainability scoring module

• Web dashboard (self-hostable)

• Fully open-source license (MIT / Apache 2.0)

Core functionality will not depend on proprietary APIs, complying with hackathon rules.

MVP Scope

Phase 1:

• Basic repo parser
