Codex app vs ServerEngine

The Codex app runs OpenAI's agents. ServerEngine runs everyone's: Codex CLI on your ChatGPT subscription, Claude Code, OpenRouter and local models, side by side in one workspace.

Codex app

The Agent Workspace in ServerEngine: four agent panels in a grid work on their own jobs at the same time - a landing page, generative art, an analytics dashboard and an ROI calculator - each keeping its own checklist, editing files with the new lines shown as green diffs and checking its own work in a headless browser, while one of them takes a spoken follow-up asking for higher quality.

Feature by feature

	Codex app	ServerEngine
Models	OpenAI models only.	Codex CLI, Claude Code, Grok Build, OpenRouter and local Ollama, chosen per agent.
Your existing subscription	Included in ChatGPT plans, drawing on the plan's usage limits.	Runs on the ChatGPT, Claude or Grok subscription you already have, or your own OpenRouter key. One provider runs dry, switch the agent to another.
Agent Workspace	Agents run in parallel, but as threads in a sidebar. You read one at a time.	A grid of agents side by side on different models at once. Put Claude and Codex on the same problem and watch both. Every session is saved and restored on startup.
Talk or type	Work is driven by typed prompts. Voice is not among Codex's announced features.	Speak your prompt with local speech-to-text, and hear the answer once the task is done.
Memory	Remembers preferences and workflows, inside OpenAI's own apps.	One memory shared across every model and provider, filed per work folder, growing into a neuron you can open and manage in the chat.
From your phone	Steer your desktop from the ChatGPT mobile app.	Slack and Discord reach the agents in your workspace, one channel per agent. WhatsApp reaches the main chat, approvals included.
Agents on a schedule	Automations, and Codex can schedule future work for itself.	Any prompt on a timetable, each with its own model, reasoning effort and allowed skills, and a live transcript while it runs.
Plans you can follow	Review the agent's changes as diffs in the thread.	Plan mode proposes the work first, then ticks each step off a checklist you watch. You decide skill by skill what has to ask first.
Code editing	Agents work on isolated worktrees, reviewed as diffs.	The fastest code editor for agents: built in pure C++, with batched calls so edits land in a fraction of the time.
Built-in skills	Computer use, an in-app browser, image generation and a large plugin catalogue.	Code, browser, computer use, image generation, GitHub, Cloudflare, Stripe, Jira and more, each switched on individually.
Work on your servers	Cloud sandboxes and the machine the app runs on.	On the Commander plan the agent also works on the servers in your network or a VPS in the cloud, inside scopes you approve.
Keep it local	The app runs on OpenAI's models in OpenAI's cloud.	Runs on your own Windows machine. With an Ollama model, nothing leaves your network.

Why type every prompt? Just talk.

Explaining a goal out loud is quicker than typing, and easier to get into detail. Speak your prompt and the agent answers back once the task is done.

Hey, I'm SENTRI. What can I help you with today?

Your agents get smarter over time

The agent learns and acts based on your conversations. Every memory is linked to a work folder. Memories grow into a neuron you can manage within the chat.

Tied to your desk? Not anymore.

Send a message from your phone. Your agents keep working while you enjoy some free time.

Two phones side by side showing the same Slack thread. On the left the agent is asked to build a landing page for a burger shop and deploy it to Cloudflare, and reports each step as it finishes. On the right it is told to use the Cloudflare skill and then to validate the page in a browser, which it does and confirms the site is live.
