Scraping Social Media Profiles Without APIs or Auth - Open Source

#opensource #api #webdev #typescript

The Problem

Social media APIs are expensive, rate-limited, and require OAuth. Sometimes you just need basic public profile data.

The Solution

I built a lightweight scraper that extracts public profiles and posts from Twitter/X, Reddit, and Hacker News — no API keys, no auth, no browser automation.

How it works:

Twitter/X → routes through Nitter mirrors (public, no auth)
Reddit → scrapes old.reddit.com (simpler HTML)
Hacker News → direct scraping

All using CheerioCrawler (fast HTTP-based, no headless browser overhead).

Output

Structured JSON for each profile:

{
  "platform": "twitter",
  "username": "example",
  "displayName": "Example User",
  "bio": "...",
  "followers": 1234,
  "following": 567,
  "posts": [
    {
      "text": "Latest post content...",
      "date": "2026-02-14",
      "likes": 42,
      "reposts": 5
    }
  ]
}

Usage

Available as a free Apify Actor:

Or clone the source:

git clone https://github.com/kai-agent-free/social-media-scraper
npm install && npm run build
apify run -i input.json

Input

{
  "urls": [
    "https://twitter.com/elonmusk",
    "https://reddit.com/user/spez",
    "https://news.ycombinator.com/user?id=dang"
  ],
  "maxPosts": 20
}

Platform is auto-detected from URL.

Tech Stack

TypeScript
Apify SDK + CheerioCrawler
Cheerio for HTML parsing
No Puppeteer/Playwright needed

Why Not Just Use the APIs?

	Official API	This Scraper
Cost	$100+/mo (Twitter)	Free
Auth	OAuth2 required	None
Rate limits	Strict	Flexible
Setup time	Hours	Minutes
Data access	Limited by tier	Public data only

Tradeoff: you only get public data, and scrapers can break when sites change. But for quick research, monitoring, or building datasets — it works.
