comfychan

A small imageboard server written in Go, using chi for routing, templ for HTML templating, htmx for interactivity, and SQLite for storage.

Requirements

Go 1.25+
templ CLI (go install github.com/a-h/templ/cmd/templ@latest), matching the version in go.mod
sqlite3 (for seeding the database)

Development

make live

Starts the app with live reload: templ watches and regenerates .templ files, and static assets (web/static) trigger a browser refresh via proxy on http://localhost:8080.

Seed the database:

make db/seed      # seed
make db/seed/f    # wipe and reseed

Building

make build

Generates templates and builds a binary at ./out/comfychan.

Configuration

COMFYCHAN_DATA_DIR — base directory for runtime data (SQLite database, uploaded media, static assets). Defaults to the current directory if unset.

Deployment

./deploy.sh builds the binary and ships it to a self-hosted server running comfychan as a systemd service (see script for target host/paths).
