One tool for runtimes, dependencies, and releases.

Cross-platform, cross-language, cross-package-manager version manager and release orchestrator.

Versionx unifies toolchain management, polyglot dependency handling, SemVer release orchestration, multi-repo coordination, policy, and first-class AI-agent integration — behind one progressive-disclosure CLI.

What's in the box

Runtime & toolchain management

Pin Node, Python, Rust, Go and more per repo. Fast native shims. A drop-in replacement for mise / asdf that shares state with the rest of the stack.

Polyglot dependency handling

Unified status, update, and audit across npm, pip, cargo, go, bundler, maven. We drive the real resolvers — we don't reimplement them.

Learn more →

Release orchestration

SemVer, CalVer, PR-title parsing, or changesets. Plan, approve, apply, roll back. Cross-repo atomic releases via a saga protocol. AI-assisted changelogs if you want them.

Learn more →

Policy engine with waivers

Declarative TOML for 80% of rules, sandboxed Luau for the rest. Waivers with expiry. Fleet-wide enforcement for platform teams.

Learn more →

Plan / apply, everywhere

Every mutation emits a JSON plan with Blake3-hashed prerequisites and a TTL. Humans approve. Agents execute. The same contract for both.

Learn more →

AI as a client, not a component

First-class MCP server. JSON-RPC daemon. Local HTTP API. No bundled LLM — you bring your own key for Anthropic, OpenAI, Gemini, or Ollama.
