I used:

Developed and served from Macintosh: macOS, BBEdit, WebStar (the most popular Mac HTTP server), Frontier (for programming, app integrations via AppleEvents, and object DB), FileMaker for integration to business data.

Developed on Macintosh, servers by Solaris or Linux: BBEdit, MacPerl, (MacPython but that may have come in 1998), Apache with CGI to Perl/Python. I think I started this to use Postgres about then.
