It all started a few years ago with Component Organizer, than BOMER and it’s now called BOMIST. The software runs locally, so no server nor setup required and you can have as many databases as you want (just run as many instances of BOMIST as you want). Additionally, it is integrated with Octopart, meaning you get plenty of useful real-time data: datasheets, descriptions, package names, values, prices as well as other useful information are automatically fetched online. Also, importing data into BOMIST is VERY easy which means you’ll get up and running in no time. BOMIST will keep improving, many new features are already inline and your feedback is always greatly appreciated. Give it a try, it’s FREE.
