The most powerful unblocked link checker, supporting these filters:

• Lightspeed Systems
• Palo Alto Systems
• FortiGuard

Also comes with many QoL (quality of life) features, including:

• Ability to be used as a User App for even better convenience
• Built-In API that can be enabled (pass --web <port>, default port is 10000)
• Check all filters, or just a single filter
• Made in TypeScript, not Python, so therefore type friendly
• Showing results ephemerally is now an option
• More detailed and user-friendly outputs

Setting up FilterChecker V2 is as easy as pie!
Assuming you already cloned the repo, and installed Bun:

1. Install packages using bun i
2. Put your bot token in your .env file, use example.env as an example
3. Start the bot with bun run start, if you wish to run the API alongside, you can turn your command into bun run start --web, and if you want to specify a custom port, bun run start --web 8080
