Lightweight tool for querying Online Judge statistics across multiple platforms

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
Querying CodeForces...
Querying AtCoder...
AtCoder done (1051 solved, 1.25s)
CodeForces done (2962 solved, 2.78s)

Total: 2962 solved / 6437 submissions

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
