    Synth — Certified App Kits for Developers | Buy, Customise, Ship

    Synth – Certified App Kits for Developers

    Buy. Customise. Ship.

    Synth sells certified, version-pinned app kits you can buy with Bits and ship today. Optional upgrade packs keep customisation bounded and transparent.

    Synth (domain synth.net.au) is a web-based marketplace for certified app kits and code assets: sellers publish production-ready, version-pinned starter kits; buyers search the marketplace catalog, open live demos where available, and complete purchases using Bits, an in-platform currency. Every kit ships with a reproducible setup guide and a supported environment matrix. New accounts receive 1,000 free Bits to start buying immediately without a card charge.

    Beyond base kit purchases, Synth offers upgrade packs — fixed-scope add-ons like deploy wiring, branding passes, and integration setup. Buyers describe their requirements through Synth Assist, an AI-powered intake that turns requests into structured checklists. A human builder reviews, confirms scope, and delivers the work. This keeps customisation bounded and accountable.

    About Synth

    Synth lists certified app kits and code assets for sale under seller-defined Bit prices, publishes public slug URLs under /snippets/[slug], and routes discovery traffic through /marketplace. Authentication, payments, and wallet balances integrate with first-party API routes under /api/; public marketing pages remain indexable.

    Operational support aligns with an Australia-associated brand (synth.net.au); contact mailboxes include support@, partners@, press@, and safety@ on that domain per the published contact grid.

    Feature modules include live demo previews where available, AI-assisted intake via Synth Assist, bounded upgrade packs, reputation and badges for sellers, and trending and featured carousels. Seller dashboards and automated Stripe checkout are road-mapped capabilities.
