AI chat platform with RAG and agents
Onyx is a self-hosted AI platform that provides chat, retrieval-augmented generation, connectors, agents, and deep research over enterprise knowledge.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
simpler private RAG platform for document Q&A; good for lightweight deployments
Private AI platform for agents, assistants and enterprise search. Built-in Agent Builder, Deep research, Document analysis, Multi-model support, and API connectivity for agents.
familiar ChatGPT-style UI with RAG and model-agnostic support; easier to deploy
User-friendly AI Interface (Supports Ollama, OpenAI API, ...)
personal AI second brain with scheduling and agents; stronger for individual workflows
Your AI second brain. Self-hostable. Get answers from the web or your docs. Build custom agents, schedule automations, do deep research. Turn any online or local LLM into your personal, autonomous AI (gpt, claude, gemini, llama, qwen, mistral). Get started - free.
enterprise knowledge base with agent builder; simpler installation, strong for KB Q&A
🔥 MaxKB is an open-source platform for building enterprise-grade agents. 强大易用的开源企业级智能体平台。
local-first AI workspace with memory, agents, and artifacts; good for privacy-focused use
A local-first AI chat workspace for models, agents, skills, plugins, search, RAG, voice, memory, and artifacts.
self-hosted AI workspace with many tools; broader but less enterprise-focused than Onyx
Self-hosted AI workspace.
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
chatbot builder with channel integrations; choose for customer-facing bots instead of internal knowledge search
The open-source hub to build & deploy GPT/LLM Agents ⚡️
agent engineering framework in TypeScript; choose when you need a code-first agent platform, not a full RAG UI
AI Agent Engineering Platform built on an Open Source TypeScript AI Agent Framework
no-code agent builder for shipping AI assistants; lacks Onyx's connectors and search
Create AI Agents in a No-Code Visual Builder or TypeScript SDK with full 2-way sync. For shipping AI assistants and multi-agent AI workflows.
web answer engine with citations; more lightweight than Onyx
Vane is an AI-powered answering engine.
live web research tool with many sources; choose for research-oriented workflows
Open-source NotebookLM alternative. Research the open web with live data(Reddit, YT, IG, TikTok, Indeed, Google Search, Maps etc) through one platform, API or MCP server. Join our Discord: https://discord.gg/ejRNvftDp9
minimal AI search engine with citations; good for simple search, lacks RAG connectors
Scira (Formerly MiniPerplx) is a minimalistic AI-powered search engine that helps you find information on the internet and cites it too. Powered by Vercel AI SDK!
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
narrow deep research alternative that runs locally; no general chat
~95% on SimpleQA (e.g. Qwen3.6-27B on a 3090). Supports all local and cloud LLMs (llama.cpp, Ollama, Google, ...). 10+ search engines - arXiv, PubMed, your private documents. Everything Local & Encrypted.
older local search-and-answer tool; unmaintained since 2023, but simple and free
FreeAskInternet is a completely free, PRIVATE and LOCALLY running search aggregator & answer generate using MULTI LLMs, without GPU needed. The user can ask a question and the system will make a multi engine search and combine the search result to LLM and generate the answer based on search results. It's all FREE to use.
Does the same job, but ships as an app. Useful to a person, not swappable into a codebase.
desktop app for local knowledge base; choose for offline or desktop use instead of server
LLM Wiki is a cross-platform desktop application that turns your documents into an organized, interlinked knowledge base — automatically. Instead of traditional RAG (retrieve-and-answer from scratch every time), the LLM incrementally builds and maintains a persistent wiki from your sources。
These projects were analysed and named onyx among their alternatives. The relationship is not symmetric — how onyx rates them is a separate judgement, made when onyx is analysed in its own right.
