playable.tools
Playable ads that pass every network the first time.
Drop in an HTML or ZIP playable and see, before you upload, whether each network will take it: file size after inlining, packaging, the install call it expects, and the APIs it bans. Then download a build for each one. Runs in your browser; your file never leaves it.
Alongside it, a small pack of game-mechanic templates in TypeScript that already build for all eight networks. Buy once, own the source.
