Rediredge is a lightweight, self-hostable domain redirector that pairs a Go data plane with a Next.js control plane. It gives you instant 30x responses without cold starts, automatic HTTPS, and a beautiful dashboard that lets non-technical teammates manage redirects on their own.

Domain redirects should be invisible infrastructure.

If you want to redirect cal.acme.com to your Calendly, you usually have to choose between two equally frustrating paths:

1. The CloudFront Path: A forty-click journey through AWS consoles, CNAME records, certificate managers, and YAML incantations that break when you sneeze.
2. The "Ask a Developer" Path: A Slack message to engineering, a ticket in the backlog, and three days of waiting for someone to update a config file.

I was tired of the friction. I wanted something that felt invisible: a system where marketing could spin up promo.example.com without pinging the engineering team, where HTTPS just worked, and where the underlying infrastructure could handle millions of requests without blinking. So I built Rediredge.

Not Another Link Shortener

You might be thinking: "Why not just use Bitly?"

Link shorteners solve a different problem. They give you a generic bit.ly/xyz123 that lives on someone else’s domain. That’s fine for a tweet, but terrible for your brand.

When you use a link shortener for business-critical redirects, you’re handing your SEO juice to a third party. Search engines see bit.ly, not yourcompany.com. You lose domain authority, you lose brand recognition, and you’re at the mercy of another company’s uptime.

Rediredge flips the script. Your redirects live on your domains. go.acme.com/demo points to your demo booking page, and search engines attribute the link equity to you. It’s personalized, it’s branded, and you own the infrastructure.

How It Actually Works

The best infrastructure is the infrastructure you forget exists.

When someone on your team needs a new redirect, they shouldn’t need to understand DNS propagation or TLS certificates. With Rediredge, you open the dashboard, type the source domain, paste the destination, and hit save. That’s it.

Behind the scenes, the system handles TXT-based domain verification, provisions TLS certificates via ACME, and pushes the new rule to a Redis read model that the Go redirector queries in sub-millisecond time. But to the user? It’s just a form.

That’s the core philosophy: Redirects are a product concern, not a DevOps ticket.

Self-Host or Let Us Handle It

Rediredge is designed for flexibility.

Option 1: Hosted (zero setup) Use our horizontally-scaled service. We operate the Go redirectors, manage TLS/ACME, and handle the infrastructure. You bring your domains; we handle the rest.

Option 2: Self-Host (one command) Run the data plane on your own infrastructure while we manage the control plane. Clone the repo, run docker compose up -d, and you’re live.

# Your server (self-hosted)
services:
redirector:
image: ghcr.io/leonardotrapani/rediredge-redirector
ports:
- "80:5498"
- "443:5499"
environment:
- REDIS_URL=redis://redis:6379
redis:
image: redis:alpine

The Go redirector handles HTTPS via autocert (ACME HTTP-01), so you don’t need a reverse proxy in front. Point your DNS, and certificates provision automatically.

Why Go + Redis?

Most redirect solutions live on the critical path of your CDN or require expensive managed services. Rediredge takes a different approach.

The architecture splits cleanly into two planes:

• Control Plane (Next.js): A dashboard for auth, domains, and redirect rules. It persists canonical configuration to Postgres and publishes a read-optimized view to Redis.
• Data Plane (Go): A stateless redirector that handles TLS via autocert, reads from Redis, and returns instant 30x responses. No cold starts. No Lambda spin-up. Just raw speed.

Client → Go Redirector (TLS + HGET) → 30x Response
↓
Redis (read model)
↑
Sync Worker ← Postgres ← Dashboard

Because the Go redirector is stateless, you can scale it horizontally by just spinning up more instances behind a load balancer. Redis handles the coordination. The dashboard is never on the hot path.

Under the Hood: The Outbox Pattern

The secret sauce that keeps everything in sync? The Outbox Pattern.

Every time you create or update a redirect in the dashboard, the change doesn’t go directly to Redis. Instead, it lands in an outbox table in Postgres. A sync worker picks up these events and applies them to Redis idempotently. Each rule carries a version field, and the worker only applies updates if the incoming version is newer.

This gives you:

• Durability: If Redis goes down, events stay in the outbox and retry with backoff.
• Consistency: No split-brain scenarios where the dashboard and redirector disagree.
• Rebuild capability: A job can truncate and repopulate the Redis namespace from Postgres at any time.

Here’s what a redirect rule looks like in the Redis read model:

{
"redirect:example.com:cal": {
"to": "https://calendly.com/acme",
"status": 308,
"preservePath": false,
"preserveQuery": true,
"enabled": true,
"version": 3
}
}

The lookup is a single HGET. No parsing. No joins. Just instant responses.
