Browse all categories alphabetically
Small categories stay out of the folder index until they contain at least 10 cards. Their projects remain in the full JSON catalog. Topics, languages and product names do not automatically create categories.
## Top projects by score
Scores help shortlist candidates. They do not establish security, maintenance quality or suitability for your use case.

## Read the data
No installation is needed for browsing. For scripts, start with index.json: a shard manifest lists each file under data/ and its record count. Older snapshots may contain a JSON array directly.
This Python 3 example prints the first five project URLs:
python
import json, urllib.request
base = "https://raw.githubusercontent.com/Arnon-hs/open-source/main/"
def read(path):
with urllib.request.urlopen(base + path) as response:
return json.load(response)
index = read("index.json")
rows = index if isinstance(index, list) else read(index["shards"][0]["path"]) if index["shards"] else []
for project in rows[:5]:
print(project["url"])
| File | Contents |
| index.json | Complete legacy array or schemaVersion: 1 manifest with total and shards |
| data/repos-.json | Full project records, including entries without a category folder |
| docs/categories.md | Alphabetical directory of browsable categories |
| category/README.md | Ranked project list for one category |
| category/owner-project.md | Human-readable project card |
Stars, forks and activity dates are snapshots from GitHub, not live browser requests. Follow the project link for current GitHub counts. Source observations and summaries can age; verify them before adoption.
