Play a round.
Five small games with global leaderboards: snake, typing, reaction time, 2048 and memory.
Games

JSON
Format, minify, validate, and query JSON.
Echo
Full request mirror — method, headers, body, and TLS info.
about
A small lab, online out of inertia.
Edge-compute experiments deployed for myself. Not a product, not a service, no SLA — things may change or break without notice.
The request analytics for tools.this1016.com record each request's path, method, status, edge location, country, hostname, user agent, and network (ASN and organization). In that record the client address is only a /24 or /48 range, never the full IP address. Cloudflare's Workers logs are separate: they keep full request details, including the IP address, for 7 days.
