FAQ
Will my extension work on the latest version of Chrome?
Yes. Every extension I build follows the Manifest V3 specification, which is the only standard currently supported by Google. You will not run into deprecation or removal issues down the line.
Can you connect the extension to an external API or my own backend?
Yes. API integration is one of the most common requirements I handle. I can connect your Chrome extension to any REST API, third-party service, or a custom backend. The Standard and Premium packages include this. It can also be added to the Basic package.
Do I receive the full source code after delivery?
Yes, completely. All source files are yours with no licensing conditions or recurring fees. You can modify, publish, or hand the code to another developer at any point.
Can you help me publish to the Chrome Web Store?
Yes. The Premium package includes store submission support.
I have an existing extension built on Manifest V2. Can you migrate it?
Yes. I can audit your MV2 codebase and migrate it to Manifest V3 so it continues to function in Chrome. The cost depends on the size and complexity of the original code.
What do I need to share to get started?
A clear description of what the extension should do, which websites or pages it needs to interact with, and any design references or brand guidelines. The more specific you are upfront, the faster and cleaner the build.
What if something is not right after delivery?
Revisions are included in every package. 2 for Basic, 3 for Standard and unlimited for Premium within the agreed scope. I aim to get it right the first time, but the revisions are there if anything needs adjustment.
