GH Archive records every public event on GitHub — pushes, pull requests, issues, stars, forks, releases, and more — and archives them for analysis. The dataset spans 2011 to present, updated hourly, and exceeds 17 TB on Google BigQuery (first 1 TB/month free). Below we explore language trends, developer behavior patterns, open source ecosystem health, and the explosive growth of AI/LLM tooling — all derived from this public timeline data.

All GitHub activity — Oct 2025 → Mar 2026

Every public event across all repos on GitHub. Sampled from 18 real gharchive.org hourly files (3 per month), scaled to monthly estimates. No keyword filtering — this is the full public GitHub timeline.

~5.2M new repos created in Oct 2025 (last month trackable via GH Archive). GitHub removed CreateEvent ref_type=repository from their public Events API around Nov 2025 — new-repo creation can no longer be counted from GH Archive for later months. Branch creation activity (proxy) is shown below.

Insights

  • Python overtakes JavaScript: Python surpassed JavaScript in new repo creation in 2023 and the gap continues widening — fueled by the AI/ML explosion and data engineering growth.
  • TypeScript's rise: TypeScript has nearly quadrupled since 2020, now surpassing Java. The JavaScript → TypeScript migration is the decade's most significant language shift in web development.
  • Rust's momentum: With ~7x growth from 2020 to 2025, Rust has the highest growth rate of any language in the top 8, though absolute numbers remain modest compared to Python/TS.
  • 69% abandonment: Over two-thirds of all public repos haven't seen a push in more than a year. Most GitHub projects are experiments, tutorials, or one-off forks rather than maintained software.
  • AI project velocity: Ollama went from 400 to 98K stars in two years. The AI tooling ecosystem is growing faster than any previous GitHub trend, including the early containerization and DevOps waves.
  • Tuesday is king: Global commit activity peaks on Tuesday and drops ~55% on weekends. The Americas contribute ~38% of all activity, followed by Europe at ~32%.

Data Sources

GH Archive

Records the public GitHub timeline, archives it, and makes it accessible for further analysis. Updated hourly. Available on Google BigQuery as a public dataset.

Website →BigQuery →GitHub →

GitHub API

The underlying events API that GH Archive records. Provides 15+ event types: PushEvent, PullRequestEvent, IssuesEvent, WatchEvent, ForkEvent, and more.

Events API →Event types →

Snowflake (Cybersyn)

Alternative ingestion of GH Archive data via Cybersyn on Snowflake Marketplace. Reportedly more reliable ingestion than BigQuery for some workloads.
