Welcome to the comparison between SiteGPT and Supavec!

Here are some unique insights on SiteGPT:

SiteGPT.ai is a no-code chatbot builder focused on customer support. Point it at your site, upload docs, and you’ll have a widget in minutes. Handy, though manual retraining and “coming soon” integrations hint it’s still maturing.

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 SiteGPT and Supavec.

Customization & Branding	No-code dashboard to swap logos, colors, and welcome text in seconds. Customize appearance White-label add-on removes SiteGPT branding for a seamless look. White-label option Choose preset Personas to set tone and voice for each bot.	No pre-made UI, no theming—branding lives in whatever front-end you create. Open source means zero “Supavec” label to hide—your app, your look. Add domain checks or auth however you like in your code. It’s “white-label” by default because Supavec is API-only.

API Documentation Offers open-source SDKs—like the Python `customgpt-client`—plus Postman collections to speed integration. Open-Source SDK Backs you up with cookbooks, code samples, and step-by-step guides for every skill level.
Integration & Workflow	Embed on sites, pipe into chat channels, and auto-escalate to humans—ideal for support flows. Webhooks on Scale / Enterprise tiers trigger external actions like Zendesk tickets. Pricing & webhooks Scheduled retraining keeps the bot current with live site changes.	Think of it as a Lego brick: upload content, query matches, feed results to your LLM. No built-in triggers—external actions are on you.

Independent tests rate median answer accuracy at 5/5—outpacing many alternatives. Benchmark Results Always cites sources so users can verify facts on the spot. Maintains speed and accuracy even for massive knowledge bases with tens of millions of words.
Customization & Flexibility ( Behavior & Knowledge)	Click “Retrain” to upload new files or re-crawl a site—no tech skills required.

Analytics API Provides detailed insights for troubleshooting and ongoing optimization.
Support & Ecosystem	Email support and a “Submit a Request” form for new features or integrations. Submit a request Active blog, Product Hunt launches, and an agency partner program grow the ecosystem.	Community help via GitHub/Discord; paid plans unlock email or priority support. [Docs] Open-source means forks, PRs, and home-grown connectors are welcome. Docs are lean—mostly endpoint references rather than big tutorials. Code samples pop up in the community, but it’s not a huge library yet.	Supplies rich docs, tutorials, cookbooks, and FAQs to get you started fast.

Embed instructions Live demo plus 7-day free trial means you can test risk-free.	No drag-and-drop dashboard—everything’s via API or CLI. Meant for code-first teams who’ll bolt it into their own chat or workflow. Self-hosters can craft custom GUIs on top, but Supavec keeps the slate blank. If you want a business-user UI like CustomGPT, you’ll layer that yourself.	Offers a wizard-style web dashboard so non-devs can upload content, brand the widget, and monitor performance. Supports drag-and-drop uploads, visual theme editing, and in-browser chatbot testing. User Experience Review Uses role-based access so business users and devs can collaborate smoothly.
