| Extension Creator Our product |

Why Extension Creator uses project pricing
Not everyone needs an unlimited monthly Chrome extension builder. Some people have one useful idea, want to generate it, test it in Chrome, request a few changes, and keep the source code. Extension Creator is priced around that workflow.
One extension costs $7.99. Packages of three and ten projects lower the average cost for creators with several ideas. Every project currently includes up to 10 revisions and a complete source-code download.
Frequently asked comparison questions
Which option avoids a monthly subscription?
Extension Creator sells project packages rather than requiring a recurring subscription. The one-project package is $7.99.
Which services provide source code?
Extension Creator, PlugThis, and Kromio publicly describe downloadable or exportable source-code workflows. Always review the current plan terms before buying.
Can these extensions be published in the Chrome Web Store?
A generated project can be prepared for publishing, but no builder can guarantee approval. You are responsible for testing, privacy disclosures, permissions, listing assets, developer registration, and compliance with current Chrome Web Store policies.
Is Manus the same kind of product?
Not exactly. Manus is a broad AI-agent platform with a Chrome extension builder among many other tools. Extension Creator, PlugThis, and Kromio are more narrowly centered on extension creation.
Want one extension without another subscription?
Describe what you want, build the project, test it in Chrome, request revisions, and download the editable source files.
