Valfisk is a next-generation general purpose Discord app, built with Poise and Serenity. It can be installed by both servers and users, with differing sets of features for each.

Try it out!

• Expand source code links from GitHub, Tangled, Tangled strings, Codeberg, GitLab, and the Rust and Go playgrounds
• Fetch Lighthouse metrics for websites
• Make DNS queries to a variety of DNS-over-HTTPS resolvers
• Reminders (public by default when installed in servers, private when not)
• Translate messages using a context menu command
• Show front page posts from Hacker News and Lobsters
• Retrieve public information about a Discord user
• Render Typst documents into raster images
• Show comprehensive data on Unicode character(s) from the Unicode Character Database

• Google Safe Browsing protection (privacy-friendly)
• Moderation commands (e.g. ban, kick, timeout)
• Auditing for message edits and deletions, and member joins and leaves
• Rotate logs channels by recreating them

• Roles that rotate to random colors daily
• Apply TOML templates to channels
• Self-timeout command for members

Valfisk's Docker image is available at ghcr.io/ryanccn/valfisk:latest; it supports both linux/amd64 and linux/arm64. A Nix package, from which the Docker image is built from, is also available in the repository's Nix flake.

Valfisk reads its configuration from environment variables:

• DISCORD_TOKEN is the only required environment variable. The registered Discord application should have the "Guild Members" and "Message Content" privileged intents enabled.
• REDIS_URL is a URL to a Redis or Redis-compatible server; it is optional but highly recommended, since some features will not work well or at all without it.
• ADMIN_GUILD_ID is a guild in which commands to manage Valfisk itself will be registered. OWNERS is a comma-separated list of user IDs that are allowed to run these commands; by default it is inferred from the Discord application's metadata.
• ERROR_LOGS_CHANNEL is a channel where internal errors from Valfisk will be logged. DM_LOGS_CHANNEL is one where direct messages sent to Valfisk will be logged.
• PAGESPEED_API_KEY, SAFE_BROWSING_API_KEY, TRANSLATION_API_KEY are Google Cloud API keys for accessing the APIs required for certain features. (They can be set to the same key.)
• HOST and PORT form the address that the API server listens to. It defaults to 0.0.0.0:8080.
