Features
One desktop app to manage providers, convert protocols, track usage, and keep your workflow seamless across every tool in your stack.
Your conversation history follows you across provider switches. Official OpenAI and third-party Codex sessions merge into one shared resume-history bucket — no context lost when you switch between GLM-5.2 and official endpoints.
GLM-5.2 with ultra reasoning enables automatic task delegation. Multi-agent v2 orchestration breaks complex workflows into sub-tasks — the model decides when to delegate, so you don’t have to.
Codex’s built-in mobile remote control keeps working even with custom providers. Nexus Composer preserves your official ChatGPT login on switch, so remote control and official plugins stay active while you use GLM-5.2.
Switch coding assistants between custom endpoints and their official APIs with a single click. No config file editing, no restarts. Credential safety guards prevent stale logins from overwriting live sessions.
A local proxy converts between Anthropic Messages, OpenAI Responses, and OpenAI Chat Completions formats transparently. Your assistants speak their native API; the proxy handles the rest.
Logs every request, token count, cost, and latency through the proxy. Know exactly what each assistant is costing you, with incremental off-main-thread parsing of session logs.
Nexus GLM-5.2
Nexus Composer ships with a managed GLM-5.2 preset — 1M context window, thinking enabled, and ultra reasoning with automatic task delegation. No manual config editing required.
Open Nexus Composer and pick the coding assistant tab — Claude Code, Codex, or Claude Desktop. Each app has its own provider list.

Getting started
No complex setup. No server to configure. Just download, pick your apps, and start routing through your preferred endpoints.
STEP 01
Grab the build for your Mac — Apple Silicon or Intel. Drag to Applications and launch. The local proxy starts automatically.
STEP 02
Toggle on the coding assistants you use — Claude Code, Codex, Gemini CLI, or any of the six supported apps. Only what you need.
STEP 03
Pick a provider for each app. The proxy handles protocol conversion automatically. Switch between custom endpoints and official APIs anytime.
How it works
Nexus Composer sits between your coding assistants and model providers, translating protocols on the fly and tracking everything that passes through.
