CronBot
The Discord bot that can send a message at specified time (via cron expression).
Written in TypeScript and with these lovely modules:
You can add the bot to your server by clicking this link and choosing the server from the list. But note that it's a dev server and I may shut it down someday, so...
Run on your own
You can also self-host the bot!
The docker image is available at Docker Hub and I placed an example docker compose file at this repository (check docker-compose.host.yml).
Remember to create an app on Discord to get a token!
