Since its launch on February 24, 2025, Claude Code has generated more than 20.8 million tracked commits across over one million GitHub repositories, according to data published by claudescode.dev, an independent monitoring service that scans public commits for Anthropic’s co-authorship metadata signature. The tracker’s star-distribution data indicates the vast majority of that activity — the figure cited in reporting on this dataset is approximately 90% — is flowing into repositories with fewer than two GitHub stars, pointing to adoption concentrated among individual developers and early-stage projects.
- claudescode.dev has recorded 20,807,124 total Claude Code commits across 1,087,408 active repositories since the tool’s February 2025 launch.
- TypeScript accounts for 34.8% of all tracked commits (7.25 million), with Python at 18.9% (3.92 million) and JavaScript at 10.2% (2.13 million).
- The platform shows 8% week-over-week growth and a 61-day doubling time, though acceleration has declined by 17.9 percentage points.
- 114,785 new repositories — excluding forks — received their first recorded Claude Code commit in the past seven days.
What Happened
claudescode.dev tracks public GitHub activity by identifying the “Co-Authored-By: Claude” signature that Claude Code appends to every commit it assists with. The dashboard aggregates this data into real-time metrics covering total commit volume, new repository creation, code delta, and language distribution. Author details for the dashboard were not available at time of publication. As of late March 2026, the cumulative totals stand at 20,807,124 commits and 1,087,408 active repositories — figures representing only the publicly visible, metadata-tagged fraction of Claude Code’s actual usage footprint.
Why It Matters
The concentration in low-visibility repositories suggests Claude Code’s primary adoption wave is occurring outside established open-source communities. High-star repositories — which tend to have stricter contribution policies and more deliberate tooling choices — appear less represented in the current data. The 8% week-over-week growth rate is positive but reflects a -17.9 percentage point decline in acceleration, meaning the tool’s adoption is still expanding, just at a decelerating pace. The current doubling time of 61 days, if maintained, would put the commit count near 40 million by mid-2026.
Technical Details
The dashboard reports a net code delta of +30.7 billion lines since launch — the arithmetic result of 50,442,790,274 lines added minus 19,767,154,942 lines deleted. This gap between additions and deletions indicates that new code generation is outpacing refactoring by a ratio of roughly 2.5 to 1. TypeScript leads all languages at 34.8% of commits (7.25 million), with Python second at 18.9% (3.92 million) and JavaScript third at 10.2% (2.13 million). The earliest commit the tracker could verify dates to February 24, 2025, from the repository moinmir/ClashOfCans, carrying the message: “Change initial game setup to always have exactly 1 correct can.” The tracker notes that multiple same-day candidates may exist and flags this find as “suggestive rather than definitive.” In the seven days preceding the most recent data snapshot, 114,785 original repositories received their first observed Claude Code commit.
Who’s Affected
The activity log reflects a wide cross-section of individual and small-team projects. Recent logged commits include authentication work on it-mannetje/hogenes (magic link login with server-side row-level security), API documentation updates for bencrane/data-engine-x-api, a bug fix on ydesjardins200-coder/wavesfinancial, and orchestration logic for zseramnay/Formants, a music notation tool. One commit from standardbeagle/agnt is attributed to “Claude Opus 4.6 (1M context),” indicating that co-authorship metadata reflects the specific model version in use — a detail relevant to developers tracking which Claude version contributed to a given codebase. Anthropic’s own developer tooling ecosystem is not separately broken out in the dashboard data.
What’s Next
The tracker’s methodology covers only public commits that retain the co-authorship tag; private repositories and commits where the tag was manually removed fall outside the dataset entirely, meaning the real usage figures are higher by an unknown margin. The -17.9 percentage point deceleration in week-over-week growth is worth monitoring: if it continues at that rate, the 61-day doubling time will lengthen noticeably in the coming months. claudescode.dev continues to log activity in real time, with the most recent entries in the displayed feed timestamped March 25, 2026. No methodology documentation or authorship credits were published alongside the dashboard at time of writing.
