## Health v2 (maintenance only)
Score: 23/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 8, longevity 100
- inputs: {"age_days": 4807, "days_push": 1049, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: none
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Streamtools is a graphical toolkit from The New York Times R&D Lab for exploring, analyzing, and modifying streams of real-time data. Users connect visual blocks to build live data processing systems without programming.

## Use cases
- build live data processing pipelines visually without coding
- monitor realtime earthquake data feeds
- poll and analyze streaming API data
- prototype stream processing workflows
- explore and visualize live data streams

## When to choose
- you want a no-code visual interface for real-time data streams
- you need to quickly prototype stream processing without infrastructure
- you're on an old Go environment and want a lightweight stream tool

## When to avoid
- you need actively maintained software - development waned in 2015 and the last release was 2023
- you need typed, production-grade stream processing semantics
- you require modern Go module support or recent runtime compatibility

## Facets
- artifact type: application
- maturity: abandoned
- function: streaming, data-visualization, etl, gui, http-server
- domain: data-visualization, analytics
- platform: windows, go, cross-platform
- tags: visual-programming, data-streams, nyt-rd-lab, no-code, real-time-processing, data-engineering, real-time, linux, macos, web-server
