About

Happy, also known as Happy Coder, is a free, open source mobile and web client that lets users spawn, view, and control multiple Claude Code AI coding agent sessions on any device, phone, tablet, laptop, or desktop, by syncing them in real time using an encrypted relay architecture so that a session started on one device can be continued seamlessly on another without losing context. It comprises three coordinated components, a CLI program that runs locally to launch and monitor Claude Code, a mobile app or web app that connects securely to the CLI session using end-to-end encryption so nobody (including the relay server) can read your data, and a relay server that simply passes encrypted blobs between devices without access to the contents; this design lets developers maintain their existing tools, editors, and workflows while adding remote control capability.

About

Relay Tripping Curves PRO2 (RTC2) is Windows desktop software built by protection engineers, for protection engineers. It plots trip curves for relays, circuit breakers, and transformers on a log-log plot, verifies selectivity between devices, and generates the complete technical report that real engineering work demands. Field test sets measure, but they don't relate the reading back to the primary system, plot the curve, or leave evidence that a setting actually coordinates. RTC2 solves that. Features: 7 relay brands, each mirroring the manufacturer's real display and native nomenclature, 10 circuit breaker trip units with L/S/I/G zones, Transformer damage curve per ANSI/IEEE C57.109-2018, inrush and short-circuit current, ΔT selectivity calculation between devices, PDF reports with primary-equivalent current, curve equation, plot, and signatures, Fully bilingual (English/Spanish), 100% offline Free DEMO with no time limit. Paid editions (perpetual license, one-time payment)
