I will develop a custom chrome extension for your business
Michael J
About this gig
Turn a repetitive browser task into a custom Chrome extension. I build Manifest V3 tools for productivity, data capture and business workflows.
My own products include GhostPen for AI email drafting and PropROI for analysing property listings, with n8n workflows and Stripe subscriptions. See my portfolio for examples.
WHAT YOU GET
Basic: up to 2 agreed core features, simple popup UI and local storage where needed.
Standard: up to 3 features, custom UI and 1 API or automation integration.
Premium: up to 4 features, backend integration, agreed advanced workflows and Web Store preparation.
Every package includes source code and testing against the agreed tasks. We define each feature before ordering: for example, capturing selected page fields is one feature; exporting them is another.
Chrome is included. Firefox/Edge, AI, accounts, payments and new backend development cost extra. API, hosting and store fees are separate. Google controls store approval.
Send the websites involved, the task you repeat and your desired result. I will confirm scope, price and delivery before you order.

Expect agreed scope, testing and a clear handover. Message me with the task you want to simplify, the tools you use and your deadline.

FAQ
What types of browser extensions can you build?
Productivity tools, AI assistants, automation, research tools, data extraction and export tools, browser helpers and SaaS extensions. Please message me with your target websites and requirements so we can define each core feature before ordering.
Which browsers are included?
Chrome is included in every package. Firefox support is +$75 and Edge support is +$60, where browser APIs are compatible. Cross-browser work is scoped before ordering and is not automatically included in the package price.
Can you add AI features?
Yes. AI/LLM integration is +$75 using OpenAI, Claude, Gemini or another compatible API. You provide the relevant provider account and pay its usage fees. Complex AI workflows may require a separate custom offer.
Can the extension connect to my backend?
Yes. Standard includes one API or automation integration and a basic backend connection if needed. Premium includes backend integration, storage and advanced workflows within the agreed scope. Building a new complete backend or dashboard is quoted separately.
Can you add user accounts or payments?
Yes. Authentication/user accounts are +$95, and Stripe payments or subscriptions are +$125. These are separate extras, even with Premium. You provide the necessary service accounts; third-party fees and ongoing charges are not included.
Do I receive the source code?
Yes. Source code and testing are included in every package. Basic includes 2 revisions, Standard 3 and Premium 5. Revisions refine the agreed features; new features or major scope changes are quoted separately.
Can you publish the extension to the Chrome Web Store?
Premium includes Web Store preparation. Submission assistance is a separate +$65 extra. You use your developer account and cover any store fees. Google controls review, approval and timing, so approval is not guaranteed or included in the delivery deadline.
Can you build a complete SaaS product around the extension?
Yes, through a custom offer. Larger systems with dashboards, databases, accounts and advanced backend development are scoped separately. An n8n backend workflow is available for +$95; complex workflows may need a tailored quote.
What other extras and support options are available?
Extra core feature +$50; extra API +$50; advanced UI work beyond the package +$75; 30 days of priority support +$125. Premium already includes priority support for its agreed scope. Message me for a custom offer for extras not shown at checkout.
Do you offer extra-fast delivery?
Yes, for +$95: Basic in 2 days, Standard in 5 days or Premium in 7 days, subject to agreed scope. Normal delivery is 4, 7 or 10 days. Each extra core feature or API integration adds 1 day. Please message me first to confirm feasibility.
