Introducing NovaC 0.2 — WASM playground live

The systems language
5× better than C.

C-level performance. Rust-level safety. Go-level ergonomics. NovaC compiles straight to C99 with zero runtime overhead — so you can ship systems code that's fast, safe, and maintainable without the complexity tax.

Built by systems engineers who shipped C, Rust, and Go in production
Sub-ms incremental builds Compiles to C99 Memory-safe by default One unified CLI

Everything C should have been,
without losing what makes it great.

Memory-safe by default

Bounds-checked slices, explicit unsafe blocks, and no null pointer dereferences. Write systems code that doesn't crash in production.

Learn more

Zero-cost abstractions

Generics, traits, and pattern matching compile down to plain C with zero runtime overhead. You pay only for what you use.

Learn more

Agent Memory System

Intelligent memory management across sessions, workspaces, and repositories. Persistent learning, context retention, and adaptive assistance.

Learn more

Real module system

No more header chaos. Explicit imports, clean visibility rules, and dependency resolution built for teams shipping at scale.

Learn more

Seamless C interop

Call any C library directly. Ship NovaC alongside existing C code. Migrate incrementally without rewrites or FFI boilerplate.

Learn more

Multi-level Caching

L1 memory, L2 RocksDB, L3 distributed caching with >90% hit rates. Sub-millisecond incremental builds that scale.

Learn more

Diagnostics that help

Error messages that pinpoint the problem, explain the cause, and suggest the fix. Compiler errors that read like a senior teammate.

Learn more

One toolchain

Build, test, format, lint, docs, and package management in a single CLI. No more wrestling with Make, CMake, autotools, or vcpkg.

Learn more

Incremental builds: <5ms for single file changes

Intelligent memory that learns and adapts.
Context-aware assistance across your entire workflow.

NovaC's agent memory system remembers your preferences, patterns, and project context. It learns from every interaction to provide increasingly personalized and accurate assistance.

Persistent Learning

Remembers your coding patterns, preferred solutions, and project conventions across all workspaces and conversations.

  • Cross-workspace memory
  • Pattern recognition
  • Personalized suggestions

Session Context

Maintains conversation history and task context within active development sessions for seamless continuity.

  • Task continuity
  • Context retention
  • Session awareness

Repository Knowledge

Builds deep understanding of your codebase structure, dependencies, and development practices over time.

  • Codebase intelligence
  • Dependency awareness
  • Project insights
Memory retention: Persistent across sessions

Familiar enough to learn in an hour.
Powerful enough to ship in production.

How it compares

Pick the best of every world.

NovaC takes Rust's safety, Go's ergonomics, and C's performance — without their respective complexity, runtime, or footguns.
