In this comprehensive guide, we compare Chatbase and Supavec across various parameters including features, pricing, performance, and customer support to help you make the best decision for your business needs.

Overview

Welcome to the comparison between Chatbase and Supavec!

Here are some unique insights on Chatbase:

Chatbase.co pitches itself as a no-code RAG tool—upload a few PDFs or web pages, and you’ve got a chatbot you can drop into Slack or your site. It’s a smooth on-ramp, but if you’re planning big integrations or expect serious traffic, you’ll want to dig past the splash screen. Simplicity is great, yet it can hide limits around deep customization and scaling.

Use this overview as a jumping-off point for a closer look at how Chatbase.co stacks up when projects grow more demanding.

And here's more information on Supavec:

Supavec is an open-source RAG API for devs who want full control. Upload PDFs, Markdown, or raw text via REST and build your own connectors for other data. Flexibility is high, but you’ll write more code—there’s no one-click Google Drive or Notion sync.

The upside: you own the stack. The trade-off: extra scripting and a lack of a polished no-code UI.

Enjoy reading and exploring the differences between Chatbase and Supavec.
