Hi!
I noticed that BOMIST was referenced in the post.
Just wanted to share that it was re-written from scratch and it was just released.
You might want to give it a try:
https://bomist.comIt's now cross platform and I'd say the FREE plan is quite generous:
* local database (you can use it offline and sync with other computers if you put it on a Dropbox folder for ex)
* you can manage parts, BOMs, purchasing, storage locations
* you can attach as many documents as you want to everything
* export every table into CSV, JSON, HTML or PDF
* write notes in markdown
(disclaimer: BOMIST's developer here
)
I'd love to know what you think and if you have any suggestions they are more than welcome!
