Automation or script · Free

Best AI builder for an automation or script on a free plan

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

For someone who can follow a change, the browser pick is Replit on Starter and the editor pick is Google Antigravity on Individual.

Best fit

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

fit / 100

Start on Starter · Free Verified

The browser IDE can run scripts. A local CLI agent is better once the script lives on your machine.
Daily Agent credits and Free Mode with a daily cap, a built-in database, and one published project. The pricing page does not state one universal credit number.
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.

An async agent that takes a GitHub task and opens a pull request.

Start on Jules · Free Verified

The job it is built for: a described task, a cloud VM, and a pull request, including chores like dependency bumps and tests.
15 tasks per rolling 24 hours, 3 concurrent, on Gemini 2.5 Pro. Jules describes this plan as evaluating the agent on real work. It does not host the project.
A good fit if you can review a diff and you would rather assign the task than sit in an editor.
You drive it from a browser tab. You do not get a running hosted app back. You get a pull request.

Best fit

A free agent IDE, with higher quotas on Google AI Pro and Ultra.

Start on Individual · Free Verified

The CLI and scheduled tasks fit scripts, inside a weekly free quota.
Free. Unlimited Tab completions and Command requests, Gemini models, and a weekly agent quota. The quota is not a published prompt count. It refreshes weekly, not every five hours.
A practical free editor if you can follow the agent's changes.
It matches an editor preference, and the free tier is actually usable.

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

fit / 100

Start on Hobby · Free Verified

The CLI, your own runners, and cloud orbs fit scripts and unattended tasks. Orb time is a separate meter from model credits.
Free to Amp if you bring your own model subscription or key and run on your own machine. Cloud orbs are pay-as-you-go. Hobby includes no orb minutes and no Amp credits.
A good step if you can follow a thread and you already have a model subscription to attach.
The CLI, the web app, and the Mac app are where the work happens. It is an agent environment, not a VS Code-style editor you live in all day.

If you do not want to read code

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

1. Replit · fit 80
2. Bolt.new · fit 78 — Weak. You can generate a script-like project, and you are still in a web builder.
3. Lovable · fit 67 — 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.
