Interview with Rohit Nadhani, founder of Webyog
Generally based out of Bangalore (I visited them when I was last there), Webyog just started an office in Santa Clara, and are expanding. They boast 15,000 paid customers so far, with some big name customers: Google, Yahoo!, executive office to the US president, and more.
SQLyog is termed as an upgrade from phpMyAdmin. There is a GPL community edition, with some “power tools” that is part of the Enterprise Edition. It is very Win32 based, but easy enough to run on other OSes via WINE or some sort of virtualisation tool.
MONyog is an agentless monitoring tool. It competes directly with Enterprise Monitor from MySQL, and there is no Community edition.
All Webyog licenses are perpetual (not subscription), with updates for a year. There are also unlimited licenses (server/user).
The motto: Low priced software, but sell thousands of copies.
