Ranked for a beginner who can follow a change, then split by where they want to work. The same weights run the homepage quiz.

Best fit

A browser IDE and agent, closest thing here to an all-in-one starter.

fit / 100

Start on Core · $20/mo Verify

The browser IDE can run scripts. A local CLI agent is better once the script lives on your machine.
Fits your budget: Core at $20/mo. $20 toward more powerful models. The pricing page listed up to 30 hours of Free Mode chat and up to 60 projects on Free Mode. Credits do not roll over. The price is marked verify, so confirm the live card before you pay.
The sweet spot: an IDE you do not have to install, with an agent when you get stuck.
The IDE is in the browser, which matches this preference.

A coding agent you can run free on your own machine, or in Amp's cloud.

Start on Megawatt · $20/mo Verified

The CLI, your own runners, and cloud orbs fit scripts and unattended tasks. Orb time is a separate meter from model credits.
Fits your budget: Megawatt at $20/mo. 45,000 minutes of orb time and $20 of Amp credits, then more credits at provider list price. Unlimited public and private repositories, and your own portal domains. Soft hosting limits on the card are 1 GB of repository storage and 10 GB of monthly transfer.
A good step if you can follow a thread and you already have a model subscription to attach.
The web app is a real place to start a thread. It does not publish a hosted product the way a browser builder does.

Best fit

An editor with agents, built for people who can read a diff.

Start on Plus · $8/mo Verified

A strong fit: the agent and CLI edit and run scripts in the project you already have.
Fits your budget: Plus at $8/mo. Base weekly pool for Cursor models (Grok 4.7, Grok 4.6, Grok 4.5, and Composer 2.5), shared with Grok. Fast is off and effort is medium. No Auto, Cloud Agents, third-party models, or your own API keys. The pool size is not published as a prompt count.
A good step up once you can follow a change even if you did not write every line.
It matches an editor or terminal workflow. Cloud agents start on Premium, not on Plus.

An agentic IDE that turns a prompt into a spec, then into a diff.

fit / 100

Start on Pro · $20/user/mo Verified

The CLI, hooks, and CI review path fit scripts and repeated chores. Credits are the meter.
Fits your budget: Pro at $20/user/mo. 1,000 credits a month. Premium models, including Auto, Claude Sonnet 5, and Claude Opus 5, where those models are available. Add-on credits at $0.04. Kiro Web uses the same credits.
A practical editor once you can follow a change and you want the plan written down first.
The IDE and CLI are the product. Cloud sessions start on a paid plan.

If you do not want to read code

The order changes. Editor tools drop, even when they are famous.

1. Replit · fit 90
2. Bolt.new · fit 83 — Weak. You can generate a script-like project, and you are still in a web builder.
3. Lovable · fit 77 — A poor fit. There is no terminal workflow for scripts outside the app you are building.

Editor and CLI tools move up. Browser builders stay useful for a first UI pass.
