GitHub - vpetersson/dslf: A small link forwarder written in Rust.

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

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

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

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

Features

Feature	Description
Blazing Fast	Sub-millisecond redirects, 50k+ req/sec on modest hardware
LinkTree Page	Beautiful landing page with Catppuccin theming
Zero Database	Simple CSV/YAML config—no PostgreSQL, Redis, or external services
Tiny Footprint	5MB binary, <10MB RAM, sub-second cold starts
Privacy First	No tracking, no analytics, fully self-hosted
SEO Optimized	Open Graph, Twitter Cards, JSON-LD structured data
Accessible	WCAG compliant with semantic HTML and ARIA labels
Import Support	Migrate from Rebrandly with one command

Configuration

File	Required	Runtime Mountable	Description
`redirects.csv`	Yes	✅ Yes	Your short link redirects
`link-index.yaml`	No	❌ No (build-time)	LinkTree-style landing page config

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

Redirects (redirects.csv)

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
