Tender is built as a local-first app. That means everything happening in the app is happening in the browser, on your device.
Because Tender is running directly on your device, interactions in the app are pretty snappy. Unlike most other apps in this space, Tender doesn't have to talk to a server somewhere far away to work. You can even use the app while offline!
These integrations are run from the Tender app on your device, proxied through our servers. Our servers never access your data when you aren't using the app - all communication, syncing, uploading, etc. is done while the app is running.
Tender is built on modern web technologies.
