RADIAN

The desktop for agentic coding.

Run pi, Claude Code, Codex, and more side by side: threads, terminals, files, and diffs in one calm workspace. No lock-in.

Available at launch for macOS · Windows · Linux.
Radian running an agent: the thread shows the agent reading the beta signup route, editing it, and running the three request cases to check the fix.
Every read, edit, and command lands in the thread. Expand any step to see what changed.

Find your agent.

Radian includes its built-in agent and runs 19 external coding agents today. Each external agent keeps its own install, auth, and model path. The directory is the control plane: detect a local CLI, review an install recipe when one exists, and open a thread on that harness.

A workspace, not a wrapper.

Radian runs the agents, holds the whole working context, and keeps everything on your machine.

Every step is a row you can open.

Reads, edits, and shell commands group into the thread as they happen. Open any one to see the file it touched and what it returned.

A Radian thread with work groups expanded: read file app/api/beta/route.ts, edit file, npx tsc --noEmit, and a curl command, each marked Done.

Threads sit beside the work.

Every conversation stays in the rail with the project it belongs to. Switch between agents without losing where you were.

Every agent. One workspace.

Run Codex, Claude Code, Cursor, Pi, OpenCode, Copilot, and the rest of the roster side by side; switch mid-task without losing context.

Fork the conversation

Branch a thread at any message, explore approaches in parallel, and keep every path.

Terminal, files, diffs

The whole working context sits next to the conversation, not in another window.

Warm starts, light memory

Warm sessions share one host process, so agents start instantly at a fraction of the memory.

Your keys, your data

Bring your own provider keys. Your sessions and code live on your machine, not on our servers.

Local-first is the security model.

Your code never reaches our servers. Radian runs agents on your machine with your keys; sessions and files stay local. That architecture is what makes the standards below straightforward instead of aspirational.

GDPR

By design

Local-first leaves little personal data to process at all: your code and sessions never leave your machine, and agent requests go straight to your model provider.

EU AI Act

Tracking

We are an EU company and track the AI Act as it applies to developer tools, building to its transparency expectations from the start.

SOC 2

In preparation

Preparing for SOC 2 Type II. We say readiness, not certified, until the audit is complete, and the local-first surface keeps that audit small.

ISO 27001

In preparation

Working toward ISO 27001 alongside SOC 2, with the same rule: no certification claims before the auditors have signed.

Frequently asked questions.

Straight answers about what Radian is, where your code goes, and when you can use it.

Radian is a desktop agent workspace, not another VS Code fork with a chat panel. It includes a built-in agent and runs 19 external coding agents today - including Codex, Claude Code, Cursor, standard upstream Pi, OpenCode, GitHub Copilot, Grok Build, Cline, and more - with threads, terminals, file trees, and diffs in one focused workspace. The agent directory is the control plane for install detection, auth, and harness selection.

Bring every agent to one desk.
