CoCalc

What it does

CoCalc is a hosted workspace for directing AI agents inside durable projects. Users describe a task and point an agent at project files; the agent works with the software and terminals available in that project. The workspace offers an integrated Codex agent and Claude Code where enabled, as well as other command-line agents in project terminals. Users can inspect the saved app, report, or chart beside the conversation, ask for revisions, or continue hands-on in files, notebooks, and terminals.

The product is aimed at researchers, educators, technical teams, and institutions doing collaborative computational work. Access starts with a CoCalc account in a web browser; the CLI is an additional option for project automation from a computer. Agent access may use CoCalc membership, a Claude Pro or Max subscription, or an Anthropic API key, depending on the agent and site. Browser-driven agent work requires a project with internet access. Agents have full access to their own project; access to other projects must be granted, and ends when the agent's turn ends.

What it can do

• Direct Codex, Claude Code, or other command-line agents in project workspaces
• Work with project files, installed software, and terminals
• Review agent outputs, including apps, reports, and charts, beside the conversation
• Continue or revise agent work through conversation or direct project editing
• Share agents and projects with collaborators for review and continued work
• Run a project web browser that an agent can drive while the user watches or takes over

Works with

• OpenAI Codex
• Claude Code
• CoCalc CLI

Before you choose

• Claude Code availability depends on the site; its access can require CoCalc membership, a Claude Pro or Max subscription, or an Anthropic API key.
• Agent access to other projects requires an explicit grant; agents have full access to their own project, so grant only from a project whose collaborators you trust.
• Agent-driven web browsing requires a project with internet access; hosted resource levels and dedicated VM availability vary by membership, site, and account.
