Startup cost: $500 - $3k

Setup costs range from $500 to $3,000 depending on the tools and services you choose. At a minimum, you would need to invest in software development tools, domain registration, and hosting services. Optionally, you may consider investing in online advertising to promote your plugin. Hidden costs may include software licensing fees for certain development tools. Based on community feedback, costs can vary widely depending on individual choices. To take this side hustle seriously, I would advise budgeting around $2,000 to cover essential expenses and ensure a solid start.
