OJHunt Lite
A lightweight async Python tool for querying Online Judge (OJ) statistics across multiple platforms. Track your accepted problems and total submissions from competitive programming sites.
- Async/concurrent requests via
aiohttp - CLI and web interface
- BSD-2 Licensed
CLI
Install once, use anywhere (pipx, uv tool, or pip):
pipx install ojhunt
# or: uv tool install ojhunt
# or: pip install ojhunt
Run directly from a clone (no install needed):
git clone https://github.com/Liu233w/ojhunt-lite
cd ojhunt-lite
uv run ojhunt tourist@codeforces
Run via container (no Python needed):
docker run --rm ghcr.io/liu233w/ojhunt-lite tourist@codeforces
Example output:
$ ojhunt tourist@codeforces tourist@atcoder

Web Interface
The web interface is designed to be self-hosted. Clone the repo and deploy:
git clone https://github.com/Liu233w/ojhunt-lite
cd ojhunt-lite
uv sync
uv run fastapi run src/ojhunt/web/app.py --port 8080
Container images are available at ghcr.io/liu233w/ojhunt-lite — see docs/web.md.
Use Crawlers in Your Code
Add ojhunt as a project dependency:
uv add ojhunt
# or: pip install ojhunt
Sync (simplest):
from ojhunt.crawlers.codeforces import query
from ojhunt.crawlers import query_sync
result = query_sync(query, "tourist")
print(result.solved, result.submissions, result.solved_list)
Async (when you already have an event loop):
import asyncio, aiohttp
from ojhunt.crawlers.codeforces import query
from ojhunt.crawlers import CrawlerResult
async def main():
async with aiohttp.ClientSession() as session:
result = CrawlerResult.from_dict(await query(session, "tourist"))
print(result.solved, result.submissions, result.solved_list)
asyncio.run(main())
query_sync and CrawlerResult work with any crawler in ojhunt.crawlers.*.
Some crawlers (nit, uva) use a persistent label cache and require the full package — they cannot be used as standalone copied files.
Supported Platforms
See the src/ojhunt/crawlers/ directory. Archived crawlers (dead sites) are in archived_crawlers/.
Development
Adding crawlers, running tests, templates: docs/development.md
