Mirrored from Open VSX — locked to the VS Code family
These extensions only run inside vscode-family editors (VS Code, Cursor, Windsurf, VSCodium). They reach a fraction of the developer market and depend on the upstream VS Code extension API — not portable, not sandboxed, no provenance.
Build OXP-native → ship to every IDE
- ›Universal host support: one wasm bundle runs in JetBrains, Zed, Neovim, VS Code, Cursor, Windsurf, web playgrounds — anywhere the OXP host embeds.
- ›Wider distribution: published once to the OXP registry — discoverable across every host, with versioned releases and search ranking you actually own.
- ›Real trust: capability-scoped permissions, signed attestation, reproducible bundles. Users see exactly what your extension can do before they install.
- ›Monetisable: paid tiers, license keys, and seat management baked into the registry — no Marketplace gatekeeper.
// Open VSX Mirror
VSX Mirror
200 extensions mirrored from open-vsx.org — installable through the OXP CLI on VS Code, Cursor, Windsurf, and VSCodium.
