Agentastic vs VS Code
Last updated
VS Code is the free, cross-platform editor most developers already use, and it now runs agents directly: Copilot, Anthropic Claude, or OpenAI Codex harnesses in agent sessions, worktree isolation, cloud agents, and an integrated browser that agents can use. Agentastic is a native macOS app built around delegation rather than editing: it runs dozens of CLI agents side by side, isolates each task in a worktree, container, SSH host, or cloud VM, and puts terminals, a browser, diffs, and review passes in one place. They stack: open any Agentastic worktree in VS Code when you need an extension.
Who should choose each option
Agentastic
Choose Agentastic when you run several agents at once, use agents beyond Copilot, Claude, and Codex, or want containers, SSH hosts, and cloud VMs as isolation options on a Mac.
VS Code
Choose VS Code when you want one editor on every OS, its extension marketplace, and agents inside the editor through Copilot plans or the Claude and Codex harnesses.

Using them together
Pick VS Code from the Open in button in Agentastic's toolbar and each worktree opens in VS Code with one click, so extensions such as Cline or Continue work as usual on the branch an agent is using.
Frequently asked questions
Does Agentastic replace VS Code?
It can for core editing, terminals, source control, browser, diffs, and agent work, since it has its own editor with LSP. VS Code stays stronger when you depend on a specific extension or work on Windows or Linux, and Agentastic opens any worktree in it.
Can VS Code run several agents in parallel?
Yes. VS Code agent sessions can use Copilot, Claude, or Codex harnesses, work in a git worktree, or hand off to cloud agents (agents overview). Agentastic runs any CLI agent, not just those three, and adds containers, SSH hosts, and cloud VMs on your own accounts.
Claude Code in VS Code or in a separate app?
Claude Code's VS Code extension puts the agent beside your editor, while the CLI runs in any terminal. Agentastic runs the CLI in isolated worktrees so several sessions can work at once; see Claude Code Desktop vs CLI for how Anthropic's own surfaces differ.
Can I use VS Code extensions like Cline or Continue in an Agentastic worktree?
Yes. Open the worktree in VS Code from Agentastic and your extensions run as usual. Cline and Continue are also built-in agent definitions in Agentastic if you prefer their CLIs.
Is GitHub Copilot free?
Copilot has a free plan with limited chat and agent usage; paid plans start at $10 a month (plans). Agentastic is free and can also run GitHub's Copilot CLI as one of its agents.
Cursor vs VS Code: which should I use?
Cursor is built on the VS Code codebase and adds its own agent, Tab completions, and paid plans; VS Code stays free and adds agents through Copilot and the Claude and Codex harnesses. Either can be the editor for Agentastic worktrees; see Agentastic vs Cursor.
