Happy to hear that, thanks!
Happy to hear it was useful!
Great list - thank you. Do you mind if you can add BlueWave Uptime to the list? We already have 25 contributors and approaching 500 stars on GitHub.
Nice to see it,
Thank you.
Took a look and seems like an interesting project. My dms are open to explore collab opportunities.
Hey there, great list!
From my own experience, I think that @supabase_io is more known alternative to Firebase and Medusa can (currently) be more popular as a Shopify alternative.
Not sure if someone mentioned it already but I am also happy to talk about it - and keep in mind that it is just my opinion. I highly recommend to check all these tools if you guys are looking for OS alternatives :)
Thanks a lot for the input, and I hope it was helpful!
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)
Its an awesome product indeed, thanks for addition!
Nice article. Would love to know more alternatives. I'm starting a small startup so would love to know about the free alternatives which can help me with management or building.
Happy to hear these were useful, more on the way soon!
Great Share!
Thanks for reading, means a lot!
Used Flarum before with LDAP auth in docker. Worked like a charm! I like the concept of tags rather than "folders".
Glad to hear it was useful!
Thanks for sharing, it's very useful
Means a lot, my pleasure to help!
Regarding Focalboard, be aware of the statement in the project readme about its current status:
