Stache is a great tool to save all web pages that are useful for the development of your startup idea. Use the Stache browser extension to save a web page with just one click, and add them to a fully searchable collection you can check out on your Mac, iPhone or iPad (synced with iCloud).
Group and organise bookmarks with folders, collections and tags to index your bookmarks for different subjects. Quickly identify the page you’re looking for using the screenshots of each saved page and search the entire contents of every page to find what you want, when you need it.
In case you missed it: We've released an update with Sierra compatibility 👍🏼
