Coder 1.0

October 15, 2026 · OpenAgents

Coder 1.0 is out on macOS, Linux, and Windows.

Coder is one Coder in front of every coding agent you use: Claude Code, Codex, OpenCode, Grok Build, Devin CLI, and Cursor, or Auto, which picks for you. It works out what each step needs and sends it where it belongs. Reading, editing, running tests, and pushing go straight through. Steps that are hard to undo, such as a deploy, a merge, a secret, a payment, or a DNS change, stop and wait until you press Y to allow or N to deny.

Install

On macOS or Linux, in a terminal:

curl -fsSL https://openagents.com/cli/install.sh | bash

On Windows, in PowerShell:

irm https://openagents.com/cli/install.ps1 | iex

Then run coder in your project folder. Start here walks you through your first half hour, and the download page has every platform.

What's in 1.0

  • Every agent behind one Coder. Press Shift+Tab to step through the agents on your computer, or leave it on Auto. Type /models to pick a model: the pick sticks for that chat, and the rail names the model that answered each turn. See Choose who answers and Pin a model or use Auto.
  • OpenCode streams. OpenCode's replies arrive as they're written, and Coder handles its one-time setup the first time you use it.
  • Keys that do what you expect. Enter sends, Ctrl+Enter queues a message for later, and Shift+Enter starts a new line. See Queue messages while Coder works.
  • Guards on every step, including Windows shells (cmd and PowerShell). PowerShell that Coder can't read, such as an encoded command or a script file, is refused. See Safety and Use Coder on Windows.
  • Each chat in its own worktree in a Git repository, on Windows too. See Worktrees and changes.
  • Headless mode for scripts and other agents: openagents coder chat, with --json, --mode opencode, and --session. See Run Coder headless.
  • Projects you can share by GitHub username: openagents projects invite PROJECT --github USER. See Share a project with a teammate.

The full list, with every download and its checksum, is in the GitHub release.

What we measured

We ran 21 real, closed issues three times each, with the same big model both ways: once with Claude Code on its own, and once with a short brief and a check step in front of it. With the brief and the check, an accepted fix cost $1.84 instead of $4.00, and the median time was 121 s instead of 284 s, and as many fixes were accepted: 19 of 63 both ways. No small model ran in this study; the saving came from the brief and the check, in front of the same model. The setup, the numbers, and the scripts to run it again are in the study.
