Overview
Open Source Committee Metrics is a free report page that shows how much work goes into the open-source code behind Cardano, and who does that work. It counts code changes, review requests and logged bugs or tasks across the main code repositories (the shared online folders where each project's code lives), then breaks the activity down by company and by time zone1. Anyone who wants to know whether Cardano development is spread across many teams or concentrated in one can read it.
The reports come from Intersect, the member-based organization that coordinates Cardano development, through its Open Source Office, using data from the analytics company Bitergia2. Intersect set the reports up as a monthly series, and the archive runs from May 2024 to September 20253,4. The September 2025 edition is the newest one in the archive, so the figures on this page describe development activity up to that month and no later3.
Key Features
- A plain summary of a month's development. The report opens with a short summary of whether commits (saved code changes), pull requests (proposed changes waiting for review) and issues (logged bugs or tasks) rose or fell compared with the month before1.
- A view of who writes the code. Contributions are split by organization, including Input Output, Intersect, Tweag, Well-Typed and contributors the report lists as Unknown, so readers can see how much of the work comes from outside Input Output1.
- Activity by project. The Open Source Committee Metrics report follows busy repositories such as cardano-ledger, plutus, cardano-api and govtool, a governance tool, showing which parts of the code saw the most work1.
- Where contributors are in the world. Activity is broken down by time zone, which shows how development is shared between Europe, the Americas and the Asia-Pacific region1.
- A downloadable copy and a full archive. The report page includes a PDF version of the edition, and earlier editions sit in separate yearly archive pages for 2024 and 20251,3,4.
What to Expect
You land on a page in the Open Source Committee's documentation site, a simple website with a menu down the side. The September 2025 report starts with a summary, then moves through short sections on organizations, repositories, pull requests, issues, contributors and geography. Each section is a handful of bullet points with percentage changes, and a closing paragraph sums up the month1. No sign-up is needed to read it or to download the PDF.
The page suits people who follow Cardano governance, developers deciding where to contribute, and anyone looking for evidence on how decentralized Cardano's engineering work is. Intersect describes the reports as a way for contributors, core teams, governance bodies and community members to see how development changes from month to month2.
Because Intersect has posted no edition after September 2025, Open Source Committee Metrics works best as a historical record rather than a live tracker. Readers who want to see trends can open earlier editions in the 2024 and 2025 archives and compare months side by side3,4. The Open Source Committee itself approves the Open Source Office's yearly roadmap, manages its own budget and leads working groups, and its regular calls are open to anyone who wants to ask questions5.
