OpenAI released a sweeping update to the Codex desktop app on 17 April, rolling out to macOS users signed into ChatGPT. The headline feature is background computer use: Codex can now autonomously operate applications on a developer's Mac by seeing, clicking, and typing with its own cursor — without requiring API integration from the target application. Multiple agents can run in parallel without interfering with the user's own work in other apps. OpenAI framed the capability as particularly useful for 'testing and iterating on frontend changes, evaluating applications, and working with tools' that lack formal API access.
Alongside computer use, OpenAI launched over 90 new plugins that extend Codex into the broader development toolchain. Named integrations include Atlassian Rovo, CircleCI, CodeRabbit, GitLab Issues, Microsoft Suite, Neon by Databricks, Remotion, Render, and Superpowers. The important architectural detail is that plugins are not thin API wrappers — they are a packaging unit that can combine skills, app integrations, and MCP servers into a single capability. The update also introduces an in-app browser where developers can comment directly on web pages to give agents precise visual instructions, currently targeting localhost frontend and game development with plans to expand to broader web application control.
Two quieter features may prove more significant over time. Memory preserves context from previous sessions — preferences, corrections, gathered information — so that Codex does not start from scratch each time a developer returns to a project. Automations allow conversation threads to be reused, tasks to be scheduled autonomously, and work to resume automatically across multiple days or weeks. The combination of memory and automations moves Codex from a session-bound tool toward a persistent development partner that maintains state across the full lifecycle of a project.
For context engineers, this update puts Codex in direct competition with Anthropic's Claude Code Routines and the broader agentic infrastructure race. Background computer use is Codex's answer to Claude Code's terminal-native approach — where Claude Code operates through the command line, Codex operates through the GUI, seeing and clicking the same interface a human developer uses. The 90+ plugin ecosystem also represents a different bet from Anthropic's MCP-first strategy: OpenAI is building a curated plugin marketplace while Anthropic relies on an open protocol. Both approaches have trade-offs — plugins offer tighter integration and curation, MCP offers flexibility and community scale. The memory and multi-day automation features close the gap with Claude Code Routines' scheduled and webhook-triggered workflows. The current limitation is macOS only, with EU/UK availability and Enterprise/Education tiers expected soon.
