Herdr

Herdr (source) is “the runtime your coding agents live on”: terminals that stay alive after the window closes, spaces to group work, and a sidebar showing which agents need attention (working / blocked / done). Plus a community plugin marketplace and a Socket API for script-driven control.

Herdr does not proxy models — agents run in terminal panes as ordinary processes and inherit that terminal’s environment. Configure the agents for Mixen once and every Herdr terminal runs from a single rouble balance.

Installation

macOS (ready image) — releases.herdr.dev/app/Herdr.dmg; from the terminal:

curl -fsSL https://releases.herdr.dev/app/install.sh | sh    # macOS / Linux

powershell -c "irm https://releases.herdr.dev/app/install.ps1 | iex"   # Windows

Supported: macOS (Apple silicon), Linux (x86_64, arm64) and Windows (x86_64); there are mobile apps for iOS and Android. The source is open — github.com/herdrdev/herdr.

Setup

Herdr has no env section of its own for agents — the variables are set for the agents the usual way, through the terminal environment:

Export the variables in your shell profile (~/.bashrc, ~/.zshrc):

export ANTHROPIC_BASE_URL=https://api.mixen.ai
export ANTHROPIC_AUTH_TOKEN=mxn-your-key
export OPENAI_BASE_URL=https://api.mixen.ai/v1   # for Codex CLI

Restart Herdr (or open a new pane) and start the agent as usual: claude, codex and so on. Herdr detects the agent in the pane automatically and starts showing its state.
For native Claude session restore install the integration:

herdr integration install claude

Diagnostics: herdr agent list — what Herdr sees, herdr agent explain <target> --json — why a pane was classified that way, herdr integration status — integration status.

Herdr’s own config is ~/.config/herdr/config.toml (optional); it has no env section for agents — do not look for one.

Recommended models

Task	Model	Input / output per 1M

Full tables with cache columns — in the catalog.

Troubleshooting

The agent in a pane hits its own account — the pane was opened before the variables were exported: open a new pane or restart Herdr.
Agent state is unknown — Herdr detects agents by screen output; do not rename the binaries, launch with the standard commands.
The 120 RPM limit is per key and shared by all panes at once; with many parallel agents spread them across several keys.
