Continue vs OpenAI Codex
Pricing
Continue: Free (open source), no longer maintained since June 2026
OpenAI Codex: Included in ChatGPT plans (Plus $20/mo, Pro from $100/mo), limited use on Free and Go
Description
Continue: Open-source AI assistant for VS Code and JetBrains. Cursor acquired it in June 2026 and the project is now read-only
OpenAI Codex: OpenAI's coding agent, which works in the ChatGPT desktop app, your terminal, your editor and the cloud on your ChatGPT plan
Pros
- The final 2.0 release still installs for free from the VS Code Marketplace, Open VSX and npm
- Works with your own API keys (Anthropic, OpenAI, Gemini and others) or local models through Ollama and LM Studio
- The code stays available under the Apache 2.0 license, so anyone can fork it
- Runs in the ChatGPT desktop app, the CLI, an IDE extension and on the web, all tied to one ChatGPT account
- Cloud tasks keep going after you close your laptop, in a reusable environment for each repo
- Reviews GitHub pull requests when you tag @Codex or turn on automatic reviews
Cons
- No longer maintained: no bug fixes, security patches or support for new models
- Hosted accounts and sign-in were retired after the acquisition
- Requires setup: picking a model, getting API keys, configuring the tool
- Free and Go plans only get limited use in the desktop app, on the smaller GPT-6 Luna model
- Plus usage is counted per five-hour window and weekly limits can also apply, and how far it goes depends on the model and the size of the task
- Running it on an API key instead of a plan drops the cloud features, such as GitHub code review and Slack
Details
Continue was the “bring your own model” approach to AI coding: a free, open-source extension for VS Code and JetBrains, plus a CLI, that connected to the LLM of your choice, from cloud APIs like Claude to local models through Ollama. You got autocomplete, chat and inline editing without a subscription.
In June 2026 Cursor acquired Continue. The team shipped a final 2.0 release on 19 June 2026, retired hosted accounts and sign-in, and made the GitHub repository read-only. The extensions still install and run with your own keys, but nothing will be fixed or updated. For the same free, model-agnostic setup with active development, use Cline inside VS Code, or Aider or Claude Code in the terminal.
Codex is OpenAI’s coding agent. You hand it a task, such as a hard-to-find bug, a refactor or a new feature, and it reads the code, makes the changes and checks its own work, using browser and computer tools where it needs them. It can run several agents in parallel, and cloud tasks carry on while your laptop is closed.
It comes with ChatGPT, so if you already pay for Plus you already have it. The same account works in the desktop app, the terminal, your editor and on iOS.
OpenAI describes Plus at $20/month as enough for a few focused coding sessions a week. Heavier use means Pro, from $100/month, which currently has no five-hour limit, or buying extra credits when you hit the limit. You can also run the CLI on an API key and pay standard API rates, which suits automation such as CI.
