After a few months of on-and-off development, the MVP is ready! We still have major things missing - actual user signup, billing and related features.
However the core product is usable and will be free to use during the "beta" (until billing is up & running :) So it should be enough to gauge general interest and gather useful feedback.
I plan to "launch" it on places where I'm most likely to get feedback (HN, relevant reddits) while I keep busy finishing the remaining bits. I've got a newsletter subscription form set up, so I'll be able to follow up with interested people.
Not expecting much for the first launch. I'd be happy with a few newsletter signups and a dozen or so constructive feedback comments, just to see if I'm on the right track.
In it for the long haul!
