Nexa v2.0.0 is Here — The First Harness Native Agent Language
1800+ tests, 12 v2.0 examples, AVM Rust 0 errors, and Nexa Code — the first Harness Native AI coding assistant. Get started in 30 seconds with one command.
Introducing Nexa Code — Harness Native AI Assistant
The first AI coding assistant built on the Harness six-tuple H=(E,T,C,S,L,V). Not a framework — a language property. Interactive REPL with autoloop, @tool, with_context, snapshot, reflect, and verify.
Nexa v2.0.0 Released — Harness Native Runtime
296 new tests, AVM Rust 0 errors 0 warnings, 12 v2.0 examples, and the first Nexa Code CLI agent. The Harness six-tuple is now runtime first-class primitives.
Introducing Harness Native — The v2.0 Vision
We're redefining what it means to be an agent programming language. Nexa v2.0 introduces the Harness Native paradigm — where agent safety is enforced by the compiler, not by runtime frameworks.
v1.3.7 Milestone — 16 Features, 1,500+ Tests
From gradual typing to pattern matching, from background jobs to HTTP servers — Nexa v1.3.7 ships with 16 major features and a battle-tested test suite.
Nexa Goes Open Source — v0.9-alpha Release
After months of stealth development, we're opening the doors. Nexa v0.9-alpha is now available under AGPL-3.0 on GitHub — with a working transpiler, 10+ examples, and a growing community.
From Zero to MVP — Building the First Transpiler
How we built the Nexa transpiler in 6 weeks: Lark parser, Earley algorithm, AST transformer with ambiguity scoring, and a Python code generator that turns .nx files into runnable code.
The Birth of Nexa — Why the World Needs a Harness Native Agent Language
Every AI developer knows the pain: prompt string concatenation, fragile JSON parsing, manual context management. We asked: what if agent safety was a language property?
