Hey makers and hunters! I'm so happy to announce that we're finally launching Supavec on PH 😸


Last year, I saw many founders/devs were confused when the shutdown of Carbon AI was announced. and that got me thinking...RAG platforms should be open source just like @Supabase.

I couldn't help but start building it on last Christmas Eve, and here we are!


What we're trying to achieve with Supavec is: Integrate your data to LLMs with simple APIs.

Today we can do these with Supavec very easily:

  • Upload PDFs/text files (and embed them)

  • Delete files

  • Get a list of your uploaded files

  • Run queries against your files

Obviously we have a long way to go but I'd like to mark our great start here on PH 🙏

@taishi_kato Interesting. Why do you think Carbon AI was shut down? And another question. Do you see the concept of RAG always being apart of the future of AI and LLM's? What do you think RAG looks like in 5-10 years?

@taishi_kato The timing with Carbon AI's shutdown really highlights why open source alternatives are so crucial for building sustainable AI infrastructure! Great work!

@sentry_co Hey André!
Carbon AI was shutdown cuz they got acquired by perplexity.

I think in the AI agent era, RAG will still be important even tho the context window size of AI models are getting bigger.


Given the costs of computing and the need for accuracy of the context and answers, we should feed AI only with necessary information imo.

@jasonleowsg Thanks Jason!

Alexander Isora 🦄

The best landing page I've seen.

Taishi Kato

@alexanderisora Thank you Alex! It's made with a great LP template from Magic UI by @dillionverma

Congrats on the launch! Best of luck🍀

Taishi Kato

@maria_anosova Thank you Maria :)

Sam @CRANQ

Let's go Taishi, seriously exciting stuff - People are only ever wanting things to be simpler & simpler so you're without a doubt hitting the pain points!

The UI is looking clean & I look forward to trying it out this weekend :)

Best of luck w/ the launch!!

Taishi Kato

@cranqnow Thanks Sam!


Let me know if you have any questions or feature requests!

BillyC @ CustomGPT.ai

Congrats on the launch @taishi_kato! As someone also building in RAG space (at CustomGPT.ai's RAG as a Service), it's great to see quality open source alternatives emerging.. The RAG choice depends on requirements and team resources - some teams need open source, and others need fully managed enterprise solutions. Having more quality options helps teams make right choice. Looking forward to seeing Supavec's impact on the RAG ecosystem. Excited to see where you take this! Congrats again on launch.

Very cool that you're launching this as open source. Are you planning to turn it into a sustainable business as well, or what's your vision for the future?

Taishi Kato

@per_clingweld Thank you Per! I have a plan to make money from the cloud hosting version of it!

Per Clingweld

@taishi_kato Ah, that makes sense! Classis pay for ease-of-use and infra.

Launching soon!

Wow, that’s incredible! Creating a RAG platform as open source is a fantastic achievement! Big congratulations on your launch! Excited to see where this goes! 🎊

Taishi Kato

@kay_arkain Thanks Kay for such kind words!

Launching soon!

Fantastic to see an open-source RAG platform! This fills a crucial gap in the market, especially for teams looking for more control and flexibility over their retrieval-augmented generation implementations.

The ability to integrate with any data source at scale is a game-changer. Being an open-source alternative to Carbon AI means teams can avoid vendor lock-in while still getting enterprise-grade RAG capabilities.

I'm particularly interested in the performance metrics and how it handles different types of data sources. Have you done any benchmarking against other RAG solutions? Would love to see some real-world use cases and deployment examples.

The free options make it accessible for developers to experiment and build proof of concepts. Great first launch that addresses a real need in the AI development space! 🔍

Taishi Kato

@xi_z Hey thanks Xi!


I don't have benchmarks/case study but I'll make one!

Dan Mindru
Launching soon!

Suuuuper interesting & ambitious product!

Browsed the GitHub and it looks solid, keeping this in my toolbelt 💪

Taishi Kato

@dan_mindru Thanks Dan! Lmk if you have any questions or feature requests!

Said Aitmbarek

Such a great move to open-source it, removes platform risk and help makers build RAG-powered apps. Awesome product & execution Taishi!

Taishi Kato

@said_aitmbarek Yes exactly!


Thanks Said!

Shivam Singh

This is awesome! Love the vision of making RAG platforms open-source—definitely needed in the space. The simplicity of integrating data with LLMs through APIs sounds super convenient. Excited to see how Supavec evolves!

Congrats on the launch! Best wishes and sending wins to the team @taishi_kato

Taishi Kato

@whatshivamdo Thanks for kind words Shivam!

Harish Kotra

Makes life easy for everyone who wants to build with AI, agents, apps or just platforms. I discovered @Supavec over a month ago during holidays and the speed with which this platform lets you go from knowledge base to embeddings to AI agents is just bliss.

I made this during holidays with a UI over @Supavec's APIs along with Gaia's AI inference: https://x.com/HarishKotra/status/1875843935718777025

Thank you @taishi_kato for making this tool!

Taishi Kato

@harishkotra Hi Harish, thanks for your support as always!

Gabriel L. Manor

Love seeing an open source RAG platform that gives devs total freedom. The APIs for uploading, deleting, and querying files are super clear. Great launch!

Taishi Kato

@gemanor Thanks Gabriel!
