now for the web
Iterate on web apps,
in your own browser.
clank preview starts your app, opens the browser, injects the overlay, and connects to your agent of
choice.
How it works
Local
Run clank preview, a drop-in
replacement for your Expo, Vite, or Next.js dev server. It starts your app, runs clankd alongside
it, and connects your agent so edits hot-reload live as you go.
Cloud
Same experience, hosted. You don't have to run clank preview yourself,
we run it for you. Build from your phone, or install our GitHub Bot for preview links on any pull request. $3.50/month after a 7-day free trial.
the mobile app
Everything you need to build and ship
Start or import a repo, point at anything, fix errors in context, and watch every change go live.
Just say what you want, it starts building.
Start fresh or bring your own
Spin up a brand-new app, or connect a GitHub repo you already have.
Catch errors, fix in one tap
The agent sees the crash live, in context. Tap once and it fixes it.
Point at anything
Crop any part of the screen to show the agent exactly what you mean.
Live on your phone
Every change hot-reloads on your device as it’s built. Tweak it, retry, ship it.
Smooth pull requests
Create a PR or contribute to an open one, straight from your phone.
Share a live preview
Flip on a public URL to share a read-only, time-limited preview, by link or QR.
Fix conflicts and failing CI
Hit a merge conflict or a red check? One tap sends it to the agent to resolve.
Manage your pull requests
Browse drafts, ready-for-review, and closed branches, and jump back into any of them.
