Useful selections. I'd also like to add this directory (OpenAlternative), which suggests open-source alternatives with filters & sort options.
Hi @kwnaidoo thanks for the feedback on Mautic, I was trying to consider introducing it in our company, and I found your comment here I would gladly be happy to have your guidance on the performance issues you mentioned, In our company we are targeting around 500k SMS per day.
We are building an open source {free} Postman alternative: Hoppscotch - API request builder for web.
Open source API development ecosystem - https://hoppscotch.io (open-source alternative to Postman, Insomnia)
Yes, we're doing a lot of work refactoring core ourselves when it comes to the performance issues with Mautic. 5.1 has a lot of improvements and we've got a backlog of PRs relating to scalability.
Perhaps you could help us with testing some time given your expertise, docs are at mau.tc/tester and we'd always welcome contributions from the changes you made to your own instance if you feel so inclined!
I would say, however, that my experiences with Joomla have been really quite positive with the 5.x series - the UX is much more friendly, there's a bunch of nice built-in accessibility features and overall after being a long term user I feel like it's the best release edition yet (using Joomla since the 1.x days).
I'd definitely add onlook.dev to the list
