Grok Build: SpaceXAI's New Terminal-Based AI Coding Agent
I am introducing Grok Build, a powerful terminal-based AI coding agent developed by SpaceXAI. This full-screen TUI understands your codebase, edits files, executes shell commands, and searches the web. You can run it interactively, headlessly for CI pipelines, or embed it in editors via the Agent Client Protocol. Built with Rust, it offers a seamless experience for developers looking to integrate advanced AI directly into their workflow.
It runs as a full-screen TUI that understands your codebase, edits files, executes shell commands, searches the web, and manages long-running tasks.

There's some surprising stuff in this codebase. For example, https://github.com/xai-org/grok-build/blob/b189869b7755d2b48... is a "self-contained terminal renderer for Mermaid diagrams", which renders a subset of Mermaid chart types using Unicode box-drawing.

Just blogged about this here[0] but at least they're not doing the usual canned PR response surrounding this.
Folks are already building on top of it:
thedavidweng/gork-build[1] — rebrand grok→"gork", stripped vendor telemetry, opt-out-only data retention, blocks x.ai auto-update. A "VSCodium-style privacy fork."
DigiGoon/digi-grok-build[2] — "dgrok" multi-provider CLI, builds from source instead of x.ai CDN.
victor-software-house/open-grok[3] — "opened to every provider."
LukaMucko/grok-build[4] — extra_body support for provider-specific request fields.
RapidAI/grok-build-desktop[5] — Tauri desktop GUI client.
mazdak/grok-build[6] — theming (Catppuccin).
thomas9120/grok-build-archival[7] — Windows telemetry-disable script.
saqoah/grok-build[8] — Kotlin MemoryBackend.

It's a shame that they exfiled private data. The model is actually good (better than opus 4.8 imo) and the harness itself is butter smooth with the potential of being the best out there.

I like that the trailing players strategy (Meta, xAI) is to open source the moat of the leaders. I think we will all benefit from it. and hopefully both the leaders and the trailing players will be much less powerful in the end.

This is not the right thing, this is the tactical thing. If you have an LLM with less than 1% of the share to begin with, you suffer from bad rep and you got caught uploading user data, one of the very few remaining tactical moves to try to climb out of it is this.

I would recommend using https://pi.dev/ over Grok Build with your xAI subscription at this point

Why bother with this when they already paid $60B for Cursor?

Interesting - seen some good experiencences in using grok by some devs, so maybe could be considered as an alternative to my beloved chinese models. Also, hard to give up on pi agent.

You can run it using Docker Sandboxes: https://github.com/docker/sbx-kits-contrib/pull/156. Doesn't replace reading the code, but `sbx policy log` shows every request the network policy blocked or allowed, and combined with an explicit allowlist, that gives you a meaningfully more secure environment to run it in.

It's awesome to see openness in these coding agents from the labs making the agents: Codex, Kimi Code, and now Grok Build.
