What a first-contribution ranking actually weighs
Ask five developers what makes a good first open-source project and you will hear five different weightings. Porchlamp makes that explicit: it scores every project on five pillars, and what you see depends on how those pillars are weighted. This post reads the list a newcomer actually sees: what the first-timer lens weighs, which projects come out on top, and what the caveats beside each row…
The first-contribution ranking on Porchlamp assigns weights to five key pillars when evaluating open-source projects for newcomers: Responsiveness, Criticality, Governance, Rigor, and Accessibility. These pillars are weighted as follows: Responsiveness at 35%, Accessibility at 30%, Governance at 15%, Criticality at 10%, and Rigor at 10%.
The ranking focuses on two main questions: whether humans respond to outside contributors, and how easy it is to make a first contribution. The top nine projects for the first-timer lens were determined from a live snapshot taken on October 16, 2026. The delta column shows how the project's rank compares to the Balanced lens; projects like open-design rank significantly higher in the first-timer lens, while others rank lower.
Coverage indicates the completeness of measurable evidence for each project, with values below 0.60 not receiving a rank. Projects above 80% coverage are given higher tiers (A or B). The ranking does not predict individual pull requests' outcomes, cover non-GitHub review processes, or include projects using auxiliary tools like Gerrit or mailing lists.
It also excludes bots, account-aged under 90 days, and recent self-closed pull requests. Users can explore the first-timer lens, investigate pull requests, and assess potential project suitability based on the ranking.
