FAQ
Will I receive the full Source Code?
Yes! In Standard and Premium Version. You will receive 100% ownership of the source code. You are free to modify it, resell it, or publish it as your own SaaS product. I do not lock my code.
Is the extension compatible with Manifest V3?
Absolutely. Google is phasing out Manifest V2, so I develop all new extensions using Manifest V3 standards to ensure your extension is future-proof and accepted by the Chrome Web Store.
Can you help me upload the extension to the Chrome Web Store?
Yes, I can guide you through the process. Please note that Google charges a one-time $5 developer fee to open an account. While I ensure the code meets all technical requirements, the final approval is subject to Google's review team.
Can this extension work on other browsers like Edge, Brave, or Firefox?
Yes! Since Microsoft Edge and Brave are based on Chromium, your extension will work there natively. If you need a version specifically for Firefox, please message me, as it may require minor code adjustments
What if the website I am scraping/automating changes its layout?
Web automation relies on the specific structure of a website (HTML/DOM). If the target site updates its design, the extension might need an update. I offer a warranty period for bugs, and I am available for long-term maintenance at a discounted rate.
Is my idea confidential?
Yes, strictly. I treat all client ideas with full confidentiality. If you require an NDA (Non-Disclosure Agreement) before we start, I am happy to sign one.
