Key Factors Determining Extension Cost

First, the complexity of features: basic extensions with minimal functionality might cost $500-$1,500, while advanced tools with AI integration or complex APIs can exceed $10,000.
Second, the platform matters: developing for Chrome, Firefox, and Safari requires separate codebases, increasing costs.
Third, ongoing maintenance is often overlooked: regular updates, security patches, and support can add 20-30% annually to the initial investment.
