Bolt.new
In-browser agent that builds and deploys full apps on tokens
Our verdict
Excellent for a same-day prototype — budget for tokens, because debugging is where the free plan runs out.
Bolt runs a coding agent inside a web container: it scaffolds, edits, runs and deploys full-stack apps from a prompt or an uploaded design, with nothing to install. Everything is metered in tokens, so a long debugging session can consume a month of allowance.
How we scored it
What we liked
- ✓Runs entirely in the browser
- ✓Hosting and databases included
- ✓Unused tokens roll over on paid plans
What to watch
- ✕Tokens burn fast while debugging
- ✕Free plan has a strict daily cap

- ◆Agent chat

Alternatives to Bolt.new
Cursor
The AI-first code editor most developers are switching to
Cursor is a VS Code fork rebuilt around AI: tab completion that predicts your next edit, chat with the whole repository in context, and an agent that plans and applies multi-file changes. Familiar enough to open without relearning, capable enough to change how you work.
Claude Code
Anthropic's terminal agent for long, multi-step coding work
Claude Code works in your terminal the way a careful engineer does: read the repo, plan the change, edit files, run tests and commands, then report back. It is the strongest of the current crop at long, multi-step work, and it burns through Claude plan limits quickly.
GitHub Copilot
Autocomplete, chat and agents inside the editors you already use
Copilot is the most widely deployed AI pair programmer: completion and inline chat in your editor, agent mode that works through a task, and review against your pull requests. It is the lowest-friction upgrade for teams already living in GitHub.
v0 by Vercel
Prompt to a polished React interface you can actually ship
v0 generates full-stack Next.js apps and components from a prompt, previews them live, and lets you refine by chat or by editing the result directly. The code is clean enough to drop into a Vercel project, and its API gives you the same agent headlessly.
