The Web engineer’s online toolbox by Ivan Zuzak.
From the post:
I wanted to compile a list of online, Web-based tools that Web engineers can use for their work in development, testing, debugging and documentation. The requirements for a tool to make the list are:
- must be a live Web application (no extensions or apps you have to host yourself),
- free to use (some kind of free plan available),
- generic applicability (not usable only for a specific application/platform),
- and must be useful to Web engineers (not just for Web site design).
If you are delivering content over the Web, you are either using or will be interested in using one or more of these tools.
