How to Find Trending Python Repos with Good First Issues

A practical method for finding active Python open source projects that are actually welcoming to first-time contributors

“Good first issue” labels are meant to flag beginner-friendly tasks, but in practice they’re wildly inconsistent — some projects tag genuinely approachable issues, others slap the label on anything unassigned. Here’s how to actually find repos worth contributing to, rather than trusting the label blindly.

Start from projects you already use

The single best filter isn’t GitHub search — it’s familiarity. Contributing to a library you already use (from the Tools & Libraries category or wherever you found it) means you already understand what problem it solves and roughly how the codebase is organised. That context is worth more than any label.

Use GitHub’s search effectively

The most reliable manual search combines several qualifiers:

is:issue is:open label:"good first issue" language:python stars:500..5000

The stars:500..5000 range matters more than it looks — projects with under 500 stars are often unmaintained or too small to have real onboarding process, and projects with over 5000 stars often have such deep contribution queues that beginner issues sit stale for months or get sniped instantly by experienced contributors. The sweet spot is active-but-not-overwhelmed.

Check activity, not just stars

Star count is a poor proxy for whether a project is actually maintained. Before opening an issue, check:

• Commit activity in the last 30 days (visible on the repo’s main page)
• Whether recent PRs from external contributors were actually merged, not just opened
• Whether issues get responses within a reasonable window (days, not months)

A repo with 200 stars and weekly commits from a responsive maintainer is a far better first-contribution target than one with 10,000 stars and a maintainer who hasn’t merged an external PR in six months.

Check our Trending page

Our Trending Python Repos page tracks rising and all-time top Python repositories by star growth, refreshed on every build. It’s not filtered by “good first issue” specifically (that data isn’t reliably available via the GitHub API at scale), but it’s a solid starting list of active, well-maintained projects to search within using the GitHub qualifier above.

Read CONTRIBUTING.md before anything else

If a repo has a CONTRIBUTING.md, read it before opening an issue or PR — it tells you the maintainer’s actual expectations (test coverage requirements, commit message format, whether to discuss before coding). Projects without one are usually a signal that contribution process is informal, which can go either way: sometimes refreshingly low-friction, sometimes chaotic.

What counts as a good first contribution

Documentation fixes, adding test coverage for an untested function, and small, well-scoped bug fixes are consistently the best entry points — they require understanding a small slice of the codebase rather than its full architecture, and they’re genuinely useful to the maintainer regardless of your experience level.
