Hi fellow engineers,
If you build with coding agents, I’d love to show you Wonder. I’m Boris, co-founder and CTO.
Two things I wanted in my own IDE: multiple Claude Code and Codex accounts, each on its own subscription, and an editable design canvas right beside my code and running app.
Used by engineers at
- Autentic
- Deeploi
- Arc
- Browserbase
- CodeRabbit
I want a development tool that keeps me close to what I’m making. Agents changed how much we can build, not how much we need to understand it.
Wonder starts with the repo you already have. Connect GitHub or open a local project; agents work on your machine with your team’s components, conventions and tools.
Each task gets its own worktree, with its chats, changes, terminal and pull request together. Explore a feature while another agent fixes a bug, or start from an existing branch. For code-only work, stay in the full-screen coding view.
Multiple accounts. Your subscriptions.
Connect several Claude Code and Codex accounts, each on its own subscription. Pick the account, model and effort for each chat, and optionally let both agents share saved memory.
Give the agent the context you’d give a teammate: a file, a design, a related chat or another worktree. Then choose how much it does on its own, from asking first to letting it run.
A design canvas. Right beside your code.
Attach a screen from your designer and ask the agent to build it in your repo with your existing components. Or bring a screen from the repo onto the canvas and work out the details visually.
Then run the app beside the design. Select an element in the Preview to add it to the chat, so the agent knows exactly what you mean. Or capture it onto the canvas, change it there and take it back to the repo.
I want that loop to feel ordinary. Fewer explanations about which button you meant. More time getting the button right.
A working result is where review begins. Read the diff, run your checks and let Codex review Claude’s code, or the other way around. You still decide what’s ready.
Then open the pull request, mark it ready, address feedback or fix failing checks, with the status right beside the changes.
Need someone to try it? On Pro, publish the app’s Preview to a link they can open in a browser, and send it with the pull request.
The canvas is collaborative too, with live editing on Pro. A designer can shape the interaction while an engineer keeps it grounded in the code.
That’s what we’re building: a place to shape an idea, make it work and get it into someone’s hands. Good software still needs your judgment. I want Wonder to give you more room to use it.
Wonder runs on Mac and Windows and is free to start. Shared canvas editing and Preview links are on Pro, and your agent subscriptions stay separate.
Bring a repo you care about and try one change, from the first prompt to the pull request. I’d love to hear what you make.
