DEVELOPERS
High-performance and open-source tooling. Free, open, and built lean.

Tools we ship
We ship developer tools built to be fast, lean, and brutally practical. Free and open-source. No bloat. No magic. Just engineering that does its job and gets out of the way.
> ENGINEERING.DOCTRINE
The best tools disappear. Configuration should be optional, not mandatory — the gap between prototype and production should be as small as the team can make it.
> PROJECTS.LIST
What we build
virtual-frame
Microfrontend projection for the web.
Compose independently deployed applications into one interface — without forcing them into the same build or runtime. Virtual Frame uses isolation and projection instead of coupling: Shadow DOM boundaries, selector-based extraction, cross-origin support, and SSR with resumption. Framework agnostic.
@lazarv/react-server
Run React anywhere.
Change where and how a component runs with a single directive. @lazarv/react-server handles serialization, streaming, and hydration for you, while staying flexible enough for routing, caching, static export, micro-frontends, and MCP servers. Runs on Node.js, Bun, and Deno.

More coming soon
Several new developer tools are already in active development. Follow @level0x40 and @lazarv on GitHub or social media to catch the next release — or drop us a line if there's something specific you'd like us to build.
