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
pipx install ojhunt # or: uv tool install ojhunt / pip install ojhunt
ojhunt tourist@codeforces
From a clone:
git clone https://github.com/Liu233w/ojhunt-lite && cd ojhunt-lite
uv run ojhunt tourist@codeforces
Or without a Python install, via container:
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
from ojhunt.crawlers import crawlers
result = crawlers.codeforces.query_sync("tourist")
print(result.solved, result.submissions, result.solved_list)
Async use, login-required crawlers, copying a single crawler file into your own
project, and every crawler's arguments: docs/library.md — or
help(ojhunt.crawlers) and help(crawlers.cses) from a Python prompt.
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
