Digital products,
built to ship
TerraVault One builds practical digital products — developer boilerplates, Notion templates, and tools — forged in real projects, documented properly, and sold with honest guarantees. No hype, no vaporware: everything in the vault works.
One-time purchases • Full ownership of what you buy • Real support from real builders
What's in the vault
Every product starts the same way: we needed it ourselves, built it properly, and polished it until it was worth your money.
MidasKit
The complete foundation for subscription mobile apps: authentication, RevenueCat in-app purchases, Stripe web checkout, free trials, and a ready-made paywall — production-grade and compiling out of the box.
- Full source code — MAUI client + ASP.NET Core backend
- Auth with OTP, JWT + rotating refresh tokens
- One interface for store, web, and trial subscriptions
- Docs that get you to a working paywall in ~10 minutes
Midas Notion Templates
Ready-to-use Notion templates that bring structure to your work — planning, tracking, and running a digital business without building your workspace from scratch.
- Duplicate into your workspace in one click
- Designed for real workflows, not screenshots
- Clean, consistent structure across templates
- One-time purchase, yours forever
More in the vault
The vault keeps growing. More developer tools, templates, and digital products are in active development — built the same way: from real use, with real documentation.
- Developer tooling & boilerplates
- Productivity systems & templates
- Announced when they're ready — not before
How we build
Four rules apply to everything TerraVault One ships:
🛠️ Built from real use
We don't build products around keyword research. Every product in the vault started as something we built for our own projects, then refined until it was worth selling.
📚 Documented like we mean it
A product you can't figure out is a product that doesn't work. Everything ships with real documentation — quick starts, setup guides, and honest notes about limitations.
🤝 Honest guarantees
No "10x your revenue" promises. Our guarantees are concrete and verifiable — like MidasKit's 14-day refund if it doesn't compile on a supported setup. We promise working products, not outcomes.
🔒 Your data stays yours
We never sell your information or reuse it for marketing you didn't ask for. Buy a product, get the product — not a lifetime of upsell emails. See our privacy policy.
About TerraVault One
TerraVault One LLC is a digital products company founded by an engineering leader with 25+ years in software — banking, healthcare, and consumer applications. After decades of building for others, the vault is where we build for builders.
The name says it: Terra — grounded, practical, built on real-world experience. Vault — a growing collection of products that hold their value. Every product is something we'd want to buy ourselves: complete, documented, and priced fairly as a one-time purchase.
