In this comprehensive guide, we compare Coveo and SimplyRetrieve 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 Coveo and SimplyRetrieve!

Here are some unique insights on Coveo:

Coveo adds RAG features to its enterprise search platform, folding AI answers into a unified index of SharePoint, Salesforce, file shares, and more. It’s powerful, especially with built-in permission filters, but setup targets larger orgs that already rely on Coveo for search.

And here's more information on SimplyRetrieve:

SimplyRetrieve is an open-source RAG stack you run on your own hardware. It keeps data in-house and pairs with open-source LLMs, giving developers full visibility into the pipeline.

Expect hands-on setup—GPU drivers, Python deps, scripts—before you’re up and running.

  • Handles model tuning and prompt optimization behind the scenes, though you can override via API when needed.
  • Defaults to WizardVicuna-13B, but you can swap in any Hugging Face model if you have the GPUs.
  • Full control over model choice, though smaller open models won’t match GPT-4 for depth.
  • Taps into top models—OpenAI’s GPT-4, GPT-3.5 Turbo, and even Anthropic’s Claude for enterprise needs.
  • Automatically balances cost and performance by picking the right model for each request. Model Selection Details

  • Powerful but best suited for organizations with an established IT team to tune and maintain it.

  • Stays current with ongoing GPT and retrieval improvements, so you’re always on the latest tech.
  • Balances top-tier accuracy with ease of use, perfect for customer-facing or internal knowledge projects.
No- Code Interface & Usability
  • Admin console and Atomic components let you get started with minimal code.
  • The end-user search UI is polished, but full generative setup usually calls for developer involvement.
  • Great for teams that already have technical resources or use Coveo today; more complex than a pure no-code tool.
  • Basic Gradio UI is developer-focused; non-tech users might find the settings overwhelming.
  • No slick, no-code admin—if you need polish or branding, you’ll build your own front end.
  • Offers a wizard-style web dashboard so non-devs can upload content, brand the widget, and monitor performance.
