About tox.li
The story behind the fastest edge-native link shortener.
Why tox.li?
Modern link shorteners have grown heavy. Between third-party tracking scripts, multiple database queries, and geographical delays, a simple link redirection can take hundreds of milliseconds.
We built tox.li (pronounced to-x-li) to prove that redirections can be near-instantaneous. By shifting the redirection layer directly to the network edge, we eliminate cold starts, database queues, and geo-latency completely.
The Edge Architecture
tox.li operates on a dual-layer architecture:
- Cloudflare Workers: Serverless code execution running in V8 isolates across Cloudflare's 300+ global data centers. Requests never travel to a single origin server—they are handled by the nearest edge node.
- Cloudflare KV: A low-latency, globally replicated key-value storage engine. Custom slugs are fetched from the KV store instantly to return the target destination URL.
Privacy & Security
Our edge nodes log anonymous interaction hits (geolocation, browser client type, referral source) strictly for dashboard reports and abuse protection.
We implement proactive phishing filters and anti-malware checkpoints. If an alias is flagged as harmful, it is blocked globally from the Cloudflare KV cache in real-time.
