I've made a living from selling developer tools for the last 10 years. It's not hard to sell to developers at all. Sure, there are a lot of people who only use free tools, but the 10% of devs who pay for their tools are still a huge market. I've bought a lot of licenses for developer tools - text editors, version control GUIs, a decompiler, multiple database clients, a client for SFTP, another one for testing HTTP APIs, multiple graphic editors, various ssh/shell tools for the phone... There's a lot of commercial dev tools out there and if you don't mind the fact that you will be dealing almost exclusively with tech dudes all the time it's a great opportunity.
