Description

Simple redirect management that works immediately. Create /go/your-slug redirects in WordPress admin — no configuration required. Optionally accelerate with Cloudflare Workers.

Built by 301.st — your redirect management experts.

What It Does

  • Instant redirects — Works right after activation. No setup, no external services needed.
  • Full control — 301/302/307/308 codes, UTM auto-append, query passthrough.
  • 404 catch-all — Redirect all 404 pages to your homepage or any URL (WP-only).
  • CSV import/export — Migrate affiliate links between sites in seconds.

How It Works

  1. WordPress handles everything by default — Redirects work via WP rewrite rules
  2. Enable edge mode (optional) — Connect Cloudflare for sub-millisecond redirects
  3. Fail-open design — If edge fails, WordPress takes over. Redirects never break.

Privacy First

  • Aggregated click stats only (daily totals)
  • No IP addresses, no cookies, no User-Agent
  • GDPR compliant — no consent required

Testing Your Redirects

External services

This plugin optionally connects to the Cloudflare API when the user explicitly enables “Edge Mode” in the Integrations settings page. This feature is entirely opt-in and the plugin works fully without it.

Cloudflare API

Cloudflare is a web infrastructure and security company that provides CDN, DNS, and edge computing services. This plugin uses the Cloudflare API to deploy a Worker script that handles redirects at the network edge (before requests reach your WordPress server), resulting in faster redirect responses.

Data sent to Cloudflare (only when edge mode is enabled by the user):

  • API token (provided by the user) — sent with each API request for authentication.
  • Redirect rules (slugs, target URLs, status codes, UTM parameters) — sent when publishing or updating the Worker snapshot.
  • Worker JavaScript code — uploaded once during edge mode setup.

No visitor data, IP addresses, cookies, or personal information is ever sent to Cloudflare by this plugin.

Privacy Policy

This plugin does not collect, store, or transmit any personal data. Click statistics are aggregated daily totals only — no IP addresses, cookies, user agents, or personal data are recorded. No consent banner is required.

  1. Upload the plugin files to /wp-content/plugins/edge-link-router/

Do I need Cloudflare to use this plugin?

No. The plugin works perfectly with just WordPress. Cloudflare integration is optional for users who want edge acceleration.

What redirect types are supported?

The plugin supports 301 (permanent), 302 (temporary), 307 (temporary, preserve method), and 308 (permanent, preserve method) redirects.

Can I add UTM parameters automatically?

Yes! Each redirect can have its own UTM parameters (source, medium, campaign) that are automatically appended to the target URL.

What happens if Cloudflare edge fails?

The plugin is designed with a “fail-open” approach. If edge has any issues, requests automatically fall back to WordPress handling. Your redirects keep working.

Does this plugin collect user data?

No personal data is collected. Statistics are aggregated (total clicks per day) with no IP addresses, user agents, or cookies stored.
