## What is Havoptic?

Havoptic is a daily-updated release tracker and comparison platform for AI coding tools.
It was built to give developers a single authoritative source for tracking the rapid pace
of change across AI coding assistants — tools that ship updates multiple times per week.

Havoptic tracks 7 tools simultaneously, normalizes their release data into a common
schema, and publishes it as structured JSON, RSS, and JSON Feed endpoints. The platform
also provides feature comparison matrices, release velocity analytics, and monthly recap
pages for each tool.

About page: https://havoptic.com/about

## Data Collection Methodology

Release data is collected by automated pipelines that run once daily via GitHub Actions.
Sources monitored per tool:

- GitHub Releases API — the primary source for CLI tools distributed via GitHub
  (Claude Code, OpenAI Codex CLI, Gemini CLI, Kiro, GitHub Copilot CLI)
- npm registry — version history for packages distributed through npm
- Official changelogs — vendor-published release notes and documentation
  (Cursor changelog at cursor.com/changelog, Windsurf release notes)

When a new version is detected:
1. Version number, release date, summary, and full release notes are extracted
2. Data is normalized into the common Havoptic release schema
3. The public releases.json dataset is updated (typically within minutes of detection)
4. Email and browser push notifications are dispatched to subscribers

The lastUpdated field in each JSON endpoint reflects the timestamp of the most recent
pipeline run. Historical data is preserved indefinitely.

## Frequently Asked Questions

### What is Havoptic?
Havoptic is an independent, daily-updated release tracking platform for AI coding tools.
It monitors and publishes version updates, changelogs, and feature changes from 7 tools:
Claude Code (Anthropic), OpenAI Codex CLI (OpenAI), Cursor (Anysphere), Gemini CLI (Google), Kiro (Amazon (AWS)), GitHub Copilot CLI (GitHub (Microsoft)), Windsurf (Codeium).

### How often does Havoptic update its data?
Release data is checked and updated once per day via automated GitHub Actions pipelines.
New releases are typically detected and published within 24 hours of the vendor releasing them.
The JSON endpoints include a lastUpdated timestamp indicating when the most recent pipeline ran.

### How does Havoptic collect release data?
Havoptic monitors GitHub Releases APIs, npm registry version histories, and official vendor
changelogs. Pipelines are automated and run on a daily schedule without human intervention.
See full methodology: https://havoptic.com/about

### Which AI coding tools does Havoptic track?
Havoptic tracks 7 AI coding tools: Claude Code (Anthropic), OpenAI Codex CLI (OpenAI), Cursor (Anysphere), Gemini CLI (Google), Kiro (Amazon (AWS)), GitHub Copilot CLI (GitHub (Microsoft)), Windsurf (Codeium).

### How can I compare two AI coding tools?
Visit https://havoptic.com/compare for the full interactive feature matrix. For direct head-to-head
comparisons use URLs like: https://havoptic.com/compare/claude-code-vs-cursor

### Is the Havoptic data available for programmatic access?
Yes. All data is publicly accessible without authentication or API keys.
- Releases: https://havoptic.com/data/releases.json
- Feature matrix: https://havoptic.com/data/feature-matrix.json
- RSS feed: https://havoptic.com/feed.xml
Full documentation: https://havoptic.com/api-docs

### Which AI coding tool ships the most releases?
Release velocity varies by tool and period. Havoptic tracks releases-per-month and average days
between releases for each tool. Current velocity data is available on each tool's page and via
the releases.json endpoint. Claude Code and Gemini CLI have historically maintained the highest
release velocity among tracked tools.

### What is the difference between Claude Code and Cursor?
Claude Code is a terminal-based CLI tool from Anthropic that works inside your existing terminal
and editor. Cursor is a full code editor (VS Code fork) with AI built directly into the editing
experience. For a detailed feature comparison: https://havoptic.com/compare/claude-code-vs-cursor
