This is a KV in memory database I built in Rust for learning purposes with a live feed of the WAL (Write Ahead Log).
This page has a control panel and a WebSocket feed.
The server is hosted in a small free-tier cloud VM, with WAF rules to allow Cloudflare proxy as the only ingress point. Cloudflare Tunnel acting as a reverse Proxy.
Play with it, inserting some data, and looking for what is inside the database. When this page is loaded, a background job is started in your browser, sending data to the server every 20 seconds. It should be showing in the feed, among the other requests that might come from other visitors.
