Onyx Code 2.0.0

Onyx Code 2.0 turns the built-in, on-device AI into a real coding agent, for free: it reads your project on its own as it works, proposes edits you review before anything touches disk, and now understands your whole codebase at no cost.

Downloading

If you're installing manually:

macOS

• Apple Silicon Mac (M1 or newer): download OnyxCode-darwin-arm64.dmg (smaller, native).
• Intel Mac, or unsure: download OnyxCode-darwin-universal.dmg (runs on both).

Open the .dmg and drag Onyx Code to /Applications/. Both macOS downloads are signed and notarized by Apple, so they pass Gatekeeper and open without security warnings.

Linux (x64)

• Debian / Ubuntu: download OnyxCode-linux-x64.deb and install it with sudo apt install ./OnyxCode-linux-x64.deb.
• Other distributions: download OnyxCode-linux-x64.AppImage, make it executable (chmod +x), and run it. On Ubuntu 24.04 (which lacks libfuse2) run it with --appimage-extract-and-run.

Windows (x64)

Windows support is on the way through winget (winget install OnyxCode), which will be the recommended way to install once it is published: it runs through Microsoft's App Installer (a trusted Microsoft Store app) with a package listing reviewed in Microsoft's community winget repository, so it verifies the download and gives a smoother first-run experience. winget is not available yet, so for now the only way to install on Windows is to download the attached OnyxCode-win32-x64-winget.exe and run it manually. It is not code-signed yet, so Windows SmartScreen warns "Windows protected your PC"; click More info, then Run anyway to continue. A code-signed installer is planned for a later release.

The *-autoupdate.zip, darwin-*.json, linux-x64.json and win32-x64.json files are plumbing for Onyx Code's
built-in auto-updater. They are not designed for manual install and will give
you a worse first-run experience than the download above.

What's New

Your local AI is now an agent, and it's free. The built-in on-device model reads the files it needs across your project on its own while it answers, then creates and changes files through edits you review and apply. You get the feel of a paid cloud assistant with none of the cost, and your code never leaves your machine.

Whole-codebase understanding, now free. Ask questions and make changes across your entire project, not just the files you have open, with no Pro subscription required.

Focused edits you approve before they land. Changes come back as targeted diffs scoped to the part of the file that actually changes, staged for your review. Nothing is written to disk until you apply it, and the assistant only reports a change as applied once it genuinely reached the file.

More extensions just work. Onyx Code now matches extensions against its own editor engine version, so a wider range of VS Code extensions, including popular AI coding tools, install and run correctly.

Drag a folder into chat. Drop a folder from the Explorer onto the chat input and it drops in a reference to that folder. The assistant then pulls in whatever it needs from inside as it works.

Bring your own embedding model at no cost. Custom embedding models for local code search are now free.

System Requirements

• macOS 11 (Big Sur) or later.
• Apple Silicon (M1 or newer) or an Intel Mac. The Universal download runs natively on both.

Installing

1. Download the .dmg that matches your Mac (see "Downloading" above).
2. Open it and drag Onyx Code into your Applications folder.
3. Launch it from Applications. Because the build is notarized, it opens without a security prompt.

Verification

This build is signed and notarized by Apple. macOS verifies it on first launch, so it opens as an app from an identified developer without security warnings.

Onyx Code 1.8.0

Local AI can now run on your graphics card on Windows, with a new control to choose GPU or CPU and clearer hardware and update screens.

What's new

GPU acceleration for local AI on Windows. Onyx Code can now run local models on your graphics card on Windows, so chat and autocomplete are much faster than running on the processor. It works with NVIDIA, AMD, and Intel graphics, with no setup and no extra downloads.

Choose where AI runs: Auto, GPU, or CPU. A new processor control lets you run local AI on your graphics card or your processor. Set it in the "Your Hardware" onboarding step, from the Command Palette with "Onyx: Select AI Processor", or in chat with /processor. Auto, the default, uses the graphics card wherever it can and the processor otherwise.

A clearer hardware screen. Onboarding now shows exactly where local AI runs on your machine, such as "GPU (Vulkan)", "GPU (Metal)", or "CPU" with the reason, so you always know what is powering your local models.

Update downloads you can see. Downloading an update now shows a progress notification while it runs, with a size readout, so you can tell it is working at a glance. When it finishes, Restart to Update switches you over with your work and settings preserved.

System requirements

• macOS 11 (Big Sur) or later, on Apple Silicon or Intel.

What's new

Codebase-aware chat finds the symbol you mean, even with a typo. Ask about a hook, function, or file and Onyx now matches it by name as well as by meaning, so a small misspelling or different casing (for example asking about "RollAccess" when the code defines useRoleAccess) still lands on the right result.

More of your codebase is searchable. The workspace index now recognizes the full range of TypeScript and JavaScript declaration styles common in React and Next projects: typed arrow-function hooks, components wrapped in memo / forwardRef / styled, single-argument arrows, and default exports. Symbols written this way now surface in chat and in /search.

A cleaner home for proposed edits. When the assistant proposes file changes, a compact "Review changes" action appears under its reply and opens a dedicated review panel docked in the bottom panel, with per-file and bulk Accept / Reject. It keeps the chat and its input clear until you choose to open it.

System requirements

• macOS 11 (Big Sur) or later, on Apple Silicon or Intel.
• Runs fully on your machine. A local model powers the core features, with no account or network connection required.

Installing

1. Download the matching .dmg above.
2. Open it and drag Onyx Code into /Applications.
3. Launch it. On first run macOS verifies the Apple notarization and opens it normally.

Already running Onyx Code? Open Check for Updates from the app menu to update in place.

Verification

This build is signed and notarized by Apple. macOS verifies it on first launch, so it opens as an app from an identified developer without security warnings.

What's new

One switch for all AI. A single setting turns every AI feature on or off at once: chat, inline autocomplete, codebase indexing, and next-edit prediction. Flip it off and Onyx Code is a clean, fully local editor with AI paused until you want it back.

Hide the chat panel. A separate setting hides the chat panel on its own while keeping autocomplete and the rest of the editor working, for when you want a quieter workspace.

Review proposed changes in one place. A dedicated Proposed Changes panel collects the file edits Onyx Code suggests, with Accept and Reject for each file (and Accept All / Reject All), so you apply exactly what you want and skip the rest.

Dependable model switching. Activating a different chat model loads the model you picked right away, so your selection is the one that answers your next message.

System requirements

• macOS 11 (Big Sur) or later, on Apple Silicon or Intel.
• 8 GB RAM minimum; 16 GB or more recommended for larger local models.
• About 1.5 GB free disk for the app, plus room for any models you download.

Installing

What's new

Sharper codebase search. Onyx Code now ships with a new code-aware embedding model that understands source code more accurately, so searching your codebase and the context Onyx Code pulls into chat are noticeably more relevant. Your projects re-index automatically the first time you open them after updating, so there's nothing to set up.

Easier model browsing. Browse Models can now sort by context length and by memory footprint (largest first), so it's quicker to find a model that fits both your hardware and the task at hand. The active sort is now clearly highlighted, and "My Embedding Models" lists only embedding models.

Pick and swap models in a comparison (Pro). You can now choose the models for a /compare run directly from the comparison view, including straight from the empty state, and swap them out at any time without leaving the screen.

Tidier chat commands. The slash-command menu in chat is now sorted alphabetically, so commands are easier to scan and find.

Download progress in view. Starting a model download now scrolls the progress into view automatically, so you can see it begin right away.

System requirements

• macOS 11 (Big Sur) or later, on Apple Silicon or Intel.
• 8 GB RAM minimum; 16 GB or more is recommended for larger local models.
• Local models run entirely on your machine, so the disk space you need depends on which models you download.

Installing

1. Download the .dmg for your Mac (see Downloading above).
2. Open it and drag Onyx Code to /Applications/.
3. Launch Onyx Code from /Applications/. Because the build is notarized by Apple, it opens without security warnings.

What's new

• Model comparison (Pro). The new /compare command runs one prompt across 2 to 5 of your installed models, side by side. Each model runs in turn on your own machine, so it works on any hardware that can run a single model, with no extra setup. You get each model's answer along with its tokens, time, and tokens per second. Keep the best answer to apply its code, or make any model your active chat model in one click. Results stay collapsed so you can expand just the ones you want to compare, and a one-click action widens the panel for a true side-by-side view.

System requirements

• macOS 11 (Big Sur) or later.
