DSLF - Damn Small Link Forwarder

A blazing fast, self-hosted link shortener and LinkTree-style page builder. Built with Rust for maximum performance and minimal resource usage.

Why DSLF? Replace bit.ly, TinyURL, and Linktree with a single, self-hosted service that's fast, private, and simple to configure.

Quick Start

1. Create redirects.csv and optionally link-index.yaml (see Configuration)
2. Copy Dockerfile.user-example to Dockerfile
3. Build and run:

docker build -t my-links .
docker run -p 3000:3000 my-links

Your links are live at http://localhost:3000.

Features

Configuration

Important: The landing page is compiled at build time—rebuild to update it. Redirects can be mounted at runtime.

Redirects (redirects.csv)

url,target,status

# Development
/gh,https://github.com/yourusername,301
/docs,https://docs.yourproject.com,301

# Marketing (302 for tracking)
/promo,https://yoursite.com/offer,302

• url — Short path (e.g., /gh)
• target — Destination URL
• status — 301 (permanent) or 302 (temporary)

Comments (#) and blank lines are supported.

LinkTree Page (link-index.yaml)

Optional landing page at /. Requires rebuild to update.

Deployment

With Landing Page (Recommended)

Use the multi-stage build with the pre-built builder image:

# Dockerfile
FROM vpetersson/dslf:builder AS static
COPY redirects.csv ./
COPY link-index.yaml ./
RUN bun run build

FROM vpetersson/dslf:latest
COPY --from=static /static/dist /app/static
COPY --from=static /static/redirects.csv /app/

docker build -t my-dslf .
docker run -p 3000:3000 my-dslf

Docker Compose:

services:
  dslf:
    build: .
    ports:
      - "3000:3000"
    restart: unless-stopped

Redirects Only

If you don't need a landing page, mount redirects.csv at runtime:

docker run -p 3000:3000 -v $(pwd)/redirects.csv:/app/redirects.csv vpetersson/dslf:latest
