Features

Quick Start

# Docker (recommended)
docker volume create codex-lb-data
docker network inspect codex-lb-net >/dev/null 2>&1 || docker network create codex-lb-net
docker run -d --name codex-lb \
  --network codex-lb-net \
  -p 2455:2455 -p 1455:1455 \
  -v codex-lb-data:/var/lib/codex-lb \
  ghcr.io/soju06/codex-lb:latest

# or uvx
uvx codex-lb

# or nix
nix run github:Soju06/codex-lb

Open localhost:2455 → Add account → Done.

Accessing the dashboard remotely for the first time? You need a one-time bootstrap token — see Getting started.

Client Setup

Point any OpenAI-compatible client at codex-lb. For Codex CLI, ~/.codex/config.toml:

model = "gpt-5.6-sol"
model_reasoning_effort = "xhigh"
model_provider = "codex-lb"

[model_providers.codex-lb]
name = "openai"  # required — enables remote /responses/compact. Lowercase since Codex 2026-05-23; older "OpenAI" stops resolving gpt-5.5
base_url = "http://127.0.0.1:2455/backend-api/codex"
wire_api = "responses"
supports_websockets = true
requires_openai_auth = true # required for codex app

Remote clients need an API key created from the dashboard.

Configuration

Environment variables with CODEX_LB_ prefix or .env.local — see .env.example and the configuration guide. SQLite is the default database backend; PostgreSQL is optional via CODEX_LB_DATABASE_URL.
