Ship 2:

I built Opencodex. Opencodex is a free, open-source coding agent that runs inside VS Code. In this newest version, Opencodex supports using a browser to test the frontend of whatever app you design with it. It supports MCP plugins, and custom providers now too. It also lets you undo the agent’s changes and actually view them. Out of the box, it works with ONLY the FREE models from OpenCode (OpenCode doesn’t even need an API Key!), OpenRouter, Groq, Gemini, and Mistral. These providers don’t even ask for payment info, making the free setup even easier. Ever since the first ship, Opencodex’s stats went from 500 installs to 1000+ installs, showing real world growth!

I gave the agent a browser and the ability to control it so now it can test the frontend to whatever it makes to further shorten the gap between this and paid vibecoding tools. I also added some new small features to make some dev workflows easier, and I made diff reviews way better and made undoing changes not require a github repo.

I built Opencodex. Opencodex is a free, open-source coding agent that runs inside VS Code, bringing a Codex-style agent loop to the editor you already use. It works with only the free models from OpenCode, OpenRouter, Groq, Gemini, and Mistral (or local Ollama models) and the default provider (Opencode) without writing keys to settings. The agent can inspect a repository, present a pinned plan, edit and delete files within the workspace boundary, run commands with configurable approvals, delegate to subagents, and use tools from configured MCP servers. In the past week since release, Opencodex has already reached over 500+ installs on the VS Code marketplace, and 40+ stars on GitHub, showing real growth and real world usage.

I just completely revamped the MCP settings. It went from just a JSON editor to a new UI that supports fancy auth, like the ChatGPT implementation.

I just made real vibecoding free.

I created Opencodex, a VS Code agent extension that gives you a workflow almost identical to OpenAI Codex, but without requiring a paid AI subscription or actually, any account at all to start. It lets you use free models from 5 different cloud providers, as well as Ollama for local models.

In just one week on the VS Code Marketplace, Opencodex has already passed 480 installs. The main difference from competitors like Cline, Continue, and Kilo Code is that while those tools are free to install, you generally still need to bring your own API key or pay for model usage. Opencodex focuses on making the entire experience accessible for free. I’m working on making MCP more intuitive by removing the current bland JSON editor to a ChatGPT style MCP manager.
