Wonder Dev View: Run many Claude Code and Codex agents in parallel
Wonder, which describes itself as an AI agent harness and playground for design and code, listed Wonder Dev View on Product Hunt on November 6, 2026. According to the Product Hunt listing, the tool lets a developer run Claude Code and Codex agents at the same time on one repository, with each task in its own git worktree, which is a separate working copy of the project. Users run the agents on their own subscriptions, can manage several of those subscriptions from one workspace, and keep each task's chats, file changes, terminal and pull request grouped together.
The review step is the distinctive part. A user can assign a different model to review the other agent's code, such as Claude checking Codex output or the reverse. The preview pane shows the running app beside the design, and a user can select an element in that preview and tell the agent what to change. Several preview versions can sit side by side on the canvas. Wonder says the product runs locally and connects agents, MCP servers, skills and rules automatically, and it offers optional shared saved memory between Claude Code and Codex.
Why it matters
For teams building AI developer tools, the launch shows where the work is moving: away from writing code by hand and toward supervising several agents and checking their output. Cross-model review is a quality tactic that a harness can offer without training or owning a model. The subscription-first design also changes the economics. A harness that runs on a user's existing plan avoids carrying token costs and credit inventory, but its reliability depends on the terms, rate limits and pricing of the model vendors it wraps.
For investors, the orchestration layer is becoming crowded. Parallel Code, Pochi and the built-in worktree features of Claude Code and the Codex app all address the same workflow. A product that depends on another company's agent cannot count on keeping the same access or pricing, so defensibility will likely come from review tooling, team features and workflow depth rather than from the worktree mechanism itself.
