I have always been an Open Source fan. So glad to know these options, good list OP!
So many tools out their actually. Glad you found it helpful.
apidog is not open source - not sure why its on this list...
Awesome list!
Thank you Costa.
Technically speaking Ollama, LM Studio and Open Devin serve quite different purposes. I like using Ollama for actually powering my local LLM workflow, didn't really use OpenDevin for a lot, but it seems to be a more Agent thing, right? Not really a ChatGPT Alternative.
Some small points but generally speaking a good list. Nice read!
Good point. They do serve different purposes. I grouped them under the local LLM/dev tooling umbrella, but yeah, OpenDevin leans more agent than ChatGPT-style. Appreciate the feedback.
Awesome roundup! 🚀 I’ve been experimenting with Supabase for a while now and it’s been a game‑changer—self‑hosting real‑time data without the Firebase lock‑in is such a relief. Can’t wait to try Coolify next for my deployments. Thanks for sharing these gems! 🙌
Glad you found it helpful! Supabase really is a solid Firebase alternative. Coolify pairs well with it if you're self-hosting definitely worth a spin. Appreciate the kind words.
Time to try some new tools and most likely get disappointed when functionality isn't at the same level as the paid ones. Can only hope that some of them will surprise me.
Totally fair take open source tools can be hit or miss compared to polished paid ones. But some of them do surprise you once you get past the setup. Hope a few make it onto your go-to list
That's true. But the most interesting part of open source software is that you own the code, so you or your team can implement the missing features if you have the skills.
You can also directly request the developers for adding a feature, which is quite hard in the case of paid softwares (big companies have mostly non-techy support agents, who can take several months to respond to a request).
Good point. No chance Microsoft would ever do some custom fine-tuning of their stuff.
Great recommendations, I use these platforms frequently and they help me
You are welcome
For what it's worth - I think Github is as free/open source as it can be. Its biggest value is hosting service - I don't see much value add self-hosting repositories unless someone is really serious about security and private control Also, don't know about your experience with Nexcloud - last time I checked it's not as straightforward as it seems.
I use open source not because they are free, but they are often well thought of, programmable, easier to migrate, and just generally better than commercial ones.
Since I've been seeing so many posts lately on "open source alternatives" - I am starting to think it might be fun to see "commercial alternative to open source software".
E.g. Are there any GOOD alternatives that works well, are robust and don't have all the paywall and hide behind cloud crap for things like (Version Control) GitHub, (Code editor) Visual Studio Code, (Operating System) Linux, (File System Utility) Everything, ....?
I mean, where should commercial companies go if they can't produce things better than free and open alternatives? It seems only commercial games (and CGI/CAD software) are better than open source counterparts.
Commercial softwares have their place for industrial work, where extensive support is required. People working in industries do not care much about privacy and customizability. They just want their software to work reliably, and an excuse to blame someone in case something goes wrong.
Wow, I tried making something similar, but it contains all tools, including paid and free.
Give a shot!
Also, there is GitLab, a well-established open-source GitHub alternative with a self-host option. In my opinion, for commercial, closed-source development, it offers a better experience than GitHub.
I used Seafile for many years as a Dropbox replacement. It's a much more focused tool than Next Cloud and has some advantages over Dropbox, it's worth checking out.
Yes! So glad to learn these open source tools, great for CS students like me!
You are welcome. I wish i had these tools when i was a CS student.
Obsidian is not open source. Logseq is however.
Gogs really isn't the preferred choice anymore. For awhile it was Gitea since Gitea is a hard fork of Gogs but now that Gitea kind of went corporate on everyone the choice for small self hosted is Forgejo. Forgejo is a hard fork of Gitea.
This list is fantastic, open-source really gives developers so much freedom and control!
In our own work, we’ve been building haveto.com, which focuses on solving a big pain point for AI startups, the high cost and complexity of hosting LLMs. With haveto, AI runs directly on a decentralized infrastructure, making it more cost-effective, transparent, and scalable without relying on big cloud providers.
We’d love to hear what others think. Have you explored decentralized AI hosting or considered moving LLMs off traditional cloud setups?
For what it's worth, LM Studio is NOT open source.
Great post! Every single Google Analytics alternative I've seen out there is better than Google Analytics, specially Plausible
some of the alternatives are really good, like GitHub alternative for a small company
Glad you found the list helpful.
Nice piece
You don't know how helpful your research is, it's truly amazing. I'll definitely try this out. Thank you!
Thank you) Awesome list)
There's convex.dev and appwrite.io in firebase alternatives as well
Very helpful list specially Coolify and Nextcloud
thanks this is awesome list
I love Obsidian, but it's not open source..
Thanks a lot for the recommendations, Mate!
Click bait. Those are not open source alternatives. They are trials and freemiums.
Not all
Obsidian is NOT open source!
I'd say anytype is closer to notion than obsidian
I would recommend AppFlowy as an actual os alt to Notion. Obsidian isn't open source as far as I know, though I absolutely could be wrong!
