## Health v2 (maintenance only)
Score: 70/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 92, release rhythm 25, longevity 100
- inputs: {"age_days": 4185, "days_push": 49, "days_rel": 286, "gap_med": null, "n_releases_24m": 1}
- flags: prerelease_only, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
CoCalc is a web-based collaborative computation platform offering Jupyter Notebooks, Sage Worksheets, a LaTeX editor, Linux terminals, and a computational whiteboard with real-time collaboration. It supports scientific computing environments like Python, SageMath, Julia, R, and Octave, and can be self-hosted or used as a hosted service.

## Use cases
- teach remote scientific courses with course management
- collaboratively edit LaTeX documents with real-time preview
- run Jupyter notebooks with Python, R, and Julia in the browser
- do mathematical computations with SageMath online
- give students a web-based Linux terminal
- collaborate on computational whiteboards in real time
- self-host a collaborative scientific computing platform

## When to choose
- you need real-time collaborative scientific computing in the browser
- you teach courses and need student project management and grading
- you want Jupyter, LaTeX, and terminals in one integrated platform
- you need SageMath, Julia, R, and Octave without local installation

## When to avoid
- you only need a lightweight local Jupyter installation
- you need a fully offline desktop application
- you require a permissive open-source license for redistribution (license is custom)

## Facets
