Certified app kits, upgrade packs, and AI-assisted intake — everything you need to ship faster.
A kit is a production-ready starter project — a downloadable ZIP containing working code, a README, and everything you need to launch. Kits are version-pinned, tested, and reviewed before they go live.
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.
Get your kit deployed to Vercel, Railway, or Fly with env wiring and a working CI check.
Replace placeholder logos, colours, and fonts with your brand identity.
Wire up Stripe test-mode checkout, webhooks, and a basic billing page.
Add Clerk, NextAuth, or Supabase Auth with protected routes and session handling.
Set up Prisma + Postgres (or your preferred ORM) with schema, seed, and migrations.
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. Commissions are non-refundable once work has started, but any unstarted commission can be cancelled for a full refund.
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 →
