v0.1 is live. v0.2 is already in flight.

Specified in WIT. Implemented on all three hosts. Rolling out as soon as conformance tests go green — no waiting on a 2027 milestone.

Native UI surfaces

ui/render painted into real tool windows on JetBrains and floating windows on Neovim. Same component vocabulary, native pixels.

Streams

Long-running stream/* RPCs for log tailing, build output, and incremental search — backpressure-aware on every host.

editor/* APIs

Read selections, apply edits, decorate ranges, and register code lenses through one editor contract that lowers to each host's native API.

surface/register

Declarative panel + view registration. One manifest entry, native chrome on every editor.

// Why OXP

The problem is 30 years old. We just solved it.

Portability

One bundle. Every editor. No compromises.

You wrote it once. It runs everywhere. Not mostly everywhere or with a few tweaks — everywhere. The .oxp runtime is a contract, not a suggestion.

  • Zero background processes
  • Universal API surface
  • Portable across every conformant runtime

Modern Stack

Your stack. Not ours.

React, Vite, Tailwind. The tools you already know. No proprietary APIs to memorize, no XML to hand-roll, no webview hacks to maintain. Just code.

  • Sandboxed micro-frontends
  • Declarative permissions (oxp.config.ts)
  • 60fps native rendering
