I realised I use a bunch of indie products to build my indie product:
Instatus by @alisalahio for status
Olvy by @iamarnob for @nshntarora for release notes
Unicornplatform by @alexanderisora for landing pages
Polypane by @kilian for responsive design
Makerlog from @matteing
Marketing Examples from @harrydry for copy
these all make my app easier to build - anyone else using indie to build indie?
