Hello Indie Hackers!
At Worksheets our initial goal was to meet our users where they work so we started with an SDK and the developer experience. Downside is that we're locked into a single language until we develop more SDK's, but we've got a robust API to make up for it in the mean time.
These days developers have a lot of options to connect and integrate with SaaS services. So how your user's interact with your services?
