About LangPop

The transparent, authoritative source for programming language popularity data.

Our Mission

LangPop exists to provide developers, researchers, and technology leaders with accurate, transparent, and up-to-date data on programming language popularity.

We believe that language selection decisions should be based on facts, not hype. LangPop aggregates data from 7 authoritative sources, updates weekly, and publishes our complete methodology so you can understand exactly how every score is calculated.

Why LangPop?

Full Transparency

Every data source, weight, and formula is documented. No black boxes, no hidden adjustments. We publish our methodology so you can audit our work.

AI/LLM Coverage

We track language popularity across AI platforms and LLM training data, something other indexes ignore. Understand not just human popularity, but AI adoption.

Weekly Updates

Data is stale the moment it's published. We update every Tuesday with fresh data from all 7 sources, so you always have current trends.

Multi-Source Composite

We aggregate GitHub, job postings, Stack Overflow, Google Trends, package managers, Reddit, and tutorials. No single source dominates.

Independent

LangPop is not affiliated with any programming language, company, or foundation. Our only bias is toward accuracy.

Our Approach

Existing language popularity indexes have limitations:

  • TIOBE measures search queries, which can reflect desperation rather than actual adoption.
  • PYPL only tracks tutorial searches and limits to 22 languages.
  • RedMonk relies heavily on Stack Overflow, which has declined 78% due to AI assistants.
  • GitHub Octoverse updates annually — data is months old before publication.

LangPop takes a different approach:

  • Multi-source weighting prevents any single source from dominating the ranking.
  • Weekly updates ensure you always have current data, not month-old snapshots.
  • Full methodology documentation lets you verify our work and understand any language's score in detail.
  • AI/LLM tracking reflects how programming languages are actually being used today.
