Below is a list of 114 tools and services that I think will be useful to people selling software products. I have either used these tools myself or know of them by reputation. I haven’t included:
- common tools you will probably have already (e.g. web browser, email client, word processor)
- programming related tools which are specific to a particular development stack (e.g. IDEs)
- categories where there are too many options (e.g. web hosting)
