Let v0 work: web search, browser use & auto-fix
Goal. Use v0 as an agent — let it look things up, test the app in a browser, and fix its own errors.
▶ Try this prompt
Open the app, click through the contact form, and fix anything that's broken. Look up the latest Next.js image-optimisation API if you need to.
v0 runs every action in an isolated sandbox, and you choose how much autonomy it has.
- 1Web search: ask about current docs or APIs and v0 searches the web in real time, showing clickable source links so you can verify what it used.
- 2Browser use: v0 can open the app it built, click through flows, critique the design, and fix issues proactively — not just generate code.
- 3Terminal + auto-fix: v0 runs bash commands in the sandbox to test and debug, and repairs errors it finds. Control this with the permission mode — Ask, Auto (default), or Full.
You'll see. v0 investigating, testing in a real browser, and repairing the app on its own — with sources you can check.
Cost. Agent steps (search, browser, terminal) run inside your messages and use tokens — a deep agentic turn can cost more credits than a simple edit.
Takeaway. v0 isn't just a generator — it's an agent that can research, test in a browser and debug, with you setting the leash.
