Pick a full-app builder that provisions the database, auth and hosting for you, and check that you can export the code before you depend on it.
You already have a codebase
Coding agents and IDE assistants respect your stack and Git history. App builders will fight it.
The interface is the hard part
UI generators produce better first drafts of layout and polish than general agents, but you still have to connect them to real data.
You are learning to code
Choose the tool that shows you the code it writes and lets you run it. Hidden code is faster today and slower every day after.
At a glance
The four questions that decide most choices: does it build the backend, does it host the result, do you get the code, and how much do you need to know first.

Full-App Builders
5
Prompt-to-app platforms. They own hosting, the database and the deploy step, so you go from idea to a live URL without touching a terminal.
Lovable
Chat your way to a full-stack app with a live preview.
A chat-first builder that writes a real React codebase, runs a live preview beside the conversation, and bundles database, auth, storage and server functions behind one backend switch.
Best for Founders and product people shipping a real, database-backed product without wanting to manage infrastructure.
Strengths
Backend, auth and file storage come wired up rather than as a separate integration project
Live preview plus error and console feedback makes debugging by conversation practical
GitHub sync means the output is a normal repo you can keep working in
Publishing and custom domains are part of the product, not an extra step
Trade-offs
Opinionated stack — you build with its React setup, not your framework of choice
Very large refactors still go faster with clear, scoped prompts than with one big ask
Usage is credit-based, so heavy iteration days cost more than light ones
Code
Full codebase, exportable to your own GitHub repository.
Pricing
Free tier to try it, then paid plans with monthly credit allowances.
A full cloud development environment where an agent creates and edits the project, with hosting, databases and secrets available in the same workspace.
Best for Learners and solo builders who want one place to code, run, host and share.
Strengths
Real environment with a terminal, packages and long-running services
Hosting and deployment sit next to the editor
Good for projects that need cron jobs, workers or scripts
Trade-offs
More moving parts to understand than a pure chat builder
Agent runs can wander on vague instructions
Compute and deployment costs are separate from agent usage
Code
Full code access; Git-based export.
Pricing
Free tier, paid plans plus usage-based agent charges.

Coding Agents
2
Agents that work directly on a codebase — planning, editing many files, running commands. They assume you already have a repo and a dev setup.
Claude Code
Terminal agent that works across a whole repository.
