A modern, full-featured web app for tracking progress across major Olympiads in Informatics: from IOI and USACO to APIO and EGOI.
Try it live: https://checklist.spoi.org.in or explore the interface using a demo account: https://checklist.spoi.org.in/demo.
- Mark problems as solved, partially solved, or assign exact scores out of 100.
- The checklist currently contains ~2,700 problems from 26 different sources.
- Start official past contests with a live timer and full performance tracking.
- For contests on oj.uz and qoj.ac, submissions are auto-synced and scored per subtask.
- Post-contest screens show rank, percentile, medal, and more. Based on actual historical results.
- oj.uz, qoj.ac, and codechef.com sync: Automatically update your checklist progress using your past submissions from three platforms.
- Arrange olympiads in any order you like, and hide those you don't want cluttering your view.
- Attach personal notes to problems for strategy, hints, or reminders, enhanced with a rudimentary markdown editor.

Requires Python 3 and node.js installed locally
Ensure you have git installed.
In any appropriate directory, run:
git clone https://github.com/AzeTurk810/oi-checklist
cd oi-checklistInstall python3 and pip from python.org. Then run pip install bs4 requests cloudscraper. You will need these packages for scraping (oj.uz, qoj.ac, codechef.com sync).
Install node.js from here.
Run npm install.
Create a .env file with the following values:
| Variable | Description |
|---|---|
DATABASE_PATH |
The exact path to a .db file that we'll make in the next step. You can set this to any path you want; for example; I use file:/Users/avighna/Desktop/oi-checklist/database.db |
ROOT_URL |
Set this to http://localhost:5501/ |
GITHUB_CLIENT_ID |
Your GitHub client ID |
GITHUB_CLIENT_SECRET |
Your GitHub client secret |
DISCORD_CLIENT_ID |
Your Discord client ID |
DISCORD_CLIENT_SECRET |
Your Discord client secret |
GOOGLE_CLIENT_ID |
Your Google client ID |
GOOGLE_CLIENT_SECRET |
Your Google client secret |
QOJ_USER |
Username for the qoj.ac account used for scraping |
QOJ_PASS |
Password for the same qoj.ac account |
Note that every variable other than the first two isn't strictly required for the app to work. The client IDs and secrets are only needed for OAuth (which you may not need if you're running this locally). The qoj.ac username and password variables are needed for qoj.ac virtual contest scraping (which, again, you may or may not need).
However, they still need to be present in the .env file. If you’re not using those features locally, you can just fill them with placeholder values.
To initialse the database, run npx prisma migrate deploy && npx prisma generate. This will create a .db file at the path we specified earlier.
To populate problem and contest data into the database, run the following two commands sequentially:
npm run syncProblems
npm run syncContestsnpm run dev starts the server: OI Checklist will be available at localhost:5501.
Bug reports, feature requests, and PRs are welcome. Feel free to file an issue or submit a fix.
The data folder contains all problem and contest data. Feel free to add problems and/or contests here. For the exact format, please refer to existing problems/contests.
Below is a brief overview of the key endpoints exposed by the backend.
