VowCode

Programming language + backend platform · Coming soon

AI writes the code.
You review up to 100× less.

VowCode is a programming language and backend platform built for AI-written code. The AI writes, a person reviews. There is about ten times less code — and for a security review you read only a tenth of that: the function headers, which say who may call each function and what it may touch.

How review works

Made for code that AI writes and people approve

10×less code than in a usual stack
10×less to read for security — only the headers
up to 100×less review work

  1. AI writes

    Agents write VowCode with checks that work even on unfinished code, diagnostics that come with fixes, and an MCP server to explore the app.

  2. You review ~10× less

    No controllers, no data-access glue, no boilerplate. What is left is the business logic itself — about a tenth of a usual codebase.

  3. Security: read the headers

    Each header lists who may call the function (👥) and which data it may read or change (🔑). The compiler guarantees the body can't reach anything else.

The most important part

Whole classes of bugs can't be written

The bugs below don't need to be caught in review — they cannot be expressed in VowCode at all. The compiler rejects them before the code ever runs, each with the exact place and a suggested fix.

Technical errors

  • Functions exposed by accident — each one declares who may call it
  • Null values
  • Untyped variables and silent reassignment
  • Hidden branches: ?:, ?., ??
  • Infinite loops and recursion
  • Database queries in a loop (N+1)
  • Loading a whole table into memory
  • Race conditions: no async, threads or shared state
  • Network or file calls inside a transaction
  • try/catch that swallows errors
  • Code paths that end without a result
  • Mixed-up IDs — an order ID can't go where a user ID is expected
  • Silent bypass of permissions
  • Undeclared access to files, network or processes
  • Hidden clock: no DateTime.Now
  • SQL strings and SQL injection
  • Magic strings
  • Division by zero and overflow

Business-logic errors

  • Status changes without declared transitions
  • Money without a currency
  • Mixing dates, instants and time zones
  • Overwriting someone else's edit
  • Double actions: double clicks, repeated jobs
  • Leaks of personal data and secrets
  • Extra fields in API responses
  • External calls without a timeout
  • Emails and phones as plain text
  • Libraries without a visible license
  • Risky code without a link to its risk record

Why VowCode

~10× less code to review

A feature in VowCode is about a tenth of the size of the same feature in a mainstream stack. Less to write, less to read, less to break.

Security review = read the headers

Every function states who may call it and exactly which data it may read or change. Reviewers check the headers — the compiler keeps the body inside them.

Program in your own language

Write names in English, French, Russian, Chinese, Hebrew — any language your team speaks. Keywords are icons, so English is not a requirement for programming.

Fast on small servers

Compiled, not interpreted, and built to run on a single small server — 1 vCPU and 512 MB of RAM, even a Raspberry Pi.

Everything in the box

Dev tools, database and data access (ORM, migrations, row-level permissions), queues, scheduled tasks, realtime subscriptions, files and search — one platform instead of a pile of libraries.

One source, backend and browser

The same code compiles to the server and to browser JavaScript. The generated JS client talks REST or WebSocket and can read and write data directly — limited by the user's permissions down to the row.

A function is a promise

The header says who may call the function (👥), what it may touch (🔑), what comes in (📥) and what goes out (📤). The compiler holds the code to that promise and generates the C# and SQL behind it.

  • Callable over REST, realtime and from the browser
  • Permission matrix built automatically
  • Errors point to the line of your source, not the generated code
