Publish your own
Anyone can build and publish a NexCoder extension. The SDK is typed, the host is sandboxed, and the review process keeps the marketplace safe.
Build with the SDK
Extensions are plain packages that hook into the NexCoder extension host. Use the typed SDK to register commands, skills, themes, or model providers.
Test locally
Load your extension from .nexcoder/extensions/ during development. Hot-reload and the agent's trajectory logs make iteration fast.
Publish to the marketplace
Sign your package, submit it for review, and verified publishers get listed with the badge. Community extensions are reviewed for safety before listing.
Start extending
Download NexCoder and install your first extension.
Extensions install in seconds and are available across the desktop IDE and the terminal CLI on your next run.
