Certified app kits, upgrade packs, and AI-assisted intake — everything you need to ship faster.
A kit is a starter project — a downloadable ZIP with code, a README, and a declared version. Kits are human-reviewed before they go live (structure, docs, listing accuracy). We do not currently auto-run or malware-scan kits; see what Certified means.
Bits are Synth's in-platform currency. 100 Bits = $1 AUD.
Filter by category, language, or keyword. Every kit shows what’s included and the price in Bits.
Click Buy, pay with Bits. The transaction is instant — no checkout page or card entry.
Download the ZIP, unpack, and start building. Code is yours to use in your projects.
Upgrade packs are fixed-scope add-ons you can request after purchasing a kit. Pick a pack, describe your requirements, and a builder delivers within the SLA window. See the Upgrade Pack Terms for pricing, scope, revisions, and refunds.
Replace placeholder logos, colours, and fonts with your brand identity.
Get your kit deployed to Vercel, Railway, or Fly with env wiring and a working CI check.
Set up Prisma + Postgres (or your preferred ORM) with schema, seed, and migrations.
Add Clerk, NextAuth, or Supabase Auth with protected routes and session handling.
Wire up Stripe test-mode checkout, webhooks, and a basic billing page.
A single scoped feature addition defined in your brief. Builder confirms feasibility before work starts.
When you request customisation, Synth Assist (AI) guides you through describing what you need. It produces a structured checklist that the builder reviews before starting work.
Estimates from the AI chat are not a confirmed quote. The builder confirms or revises pricing within 3 business days.
Commissions are capped by a slot limit so builders can maintain quality. If all slots are full, customisation is temporarily paused until active work is delivered.
Typical delivery: 3–10 business days depending on the upgrade pack.
Kits are sold as-is under the Terms of Service. Unused Bits can be refunded within 14 days of purchase. Upgrade pack refunds follow the Upgrade Pack Terms — non-refundable once work has started, full refund if cancelled before work begins.
A complete, runnable project — not a single file or snippet. It includes source code, a README, and locked dependencies so it works out of the box.
Every kit is manually reviewed for quality, documentation, and safety before listing. See our certification page for details. Learn more →
