However when bootstrapping without venture capital, open-sourcing your work may make it easy to copy you.
Is open-sourcing and running as fast as you can the only viable option for developer tools today?
* If you mean code libraries (e.g. a licensing model)? I don’t think a lot of people would pay for that these days.
* Managed solutions for sure, most developers and small companies are happy to outsource anything that reeks of devops.
* IDEs etc, yup worth every penny.
From my point of view, and a bit sour experience as well, if you want to charge money for developer tools that is the market you should focus on.
