01
AnythingLLM
open sourceMITLocal or hosted
64kaug 2026
A private AI desk for documents and agents; install it, then choose local models or somebody else's meter.
The catch vs Claude
It does not include Anthropic inference, so matching Claude's reasoning and document quality requires a separately metered Anthropic API key or a usually weaker local model.
Install, platforms & data +
platforms
desktopwebself-hostedone-click install
install
Native desktop installer, or Docker for a shared/self-hosted server
setup
A non-expert must choose a model path: download a local model with enough RAM, connect Ollama or LM Studio correctly, or bring and pay for an API key.
engines
Local llama.cpp and imported GGUF models, plus Ollama, LM Studio, LocalAI and numerous cloud providers including OpenAI, Anthropic, Google, Azure, AWS Bedrock, Groq, Mistral, Cohere, and OpenRouter.
your data
Desktop data stays in the app's local data directory; the Docker edition persists its server storage volume, including an SQLite database and the default LanceDB vector store. Configured cloud providers receive the prompts and files sent to them.

Cherry Studio
open sourceAGPL-3.0Local
50kaug 2026
A desktop model switchboard with assistants, files, agents and MCP; bring keys or make your laptop sweat.
The catch vs Claude
It does not bundle Claude usage, and its desktop-first workspace is less seamless for Claude's first-party document, project, and cross-device workflow.
Install, platforms & data +
platforms
desktopone-click install
install
Native macOS, Windows, or Linux desktop installer
setup
The installer is easy, but useful output requires either a paid provider key or downloading and running a local model that fits the machine.
engines
Supports hundreds of models through providers such as OpenAI, Anthropic, Google Gemini, OpenRouter, Azure, AWS Bedrock, Groq, DeepSeek, Mistral, Ollama, LM Studio, and other OpenAI-compatible services.
your data
Chats, API keys, assistants, settings, and local knowledge-base data are kept on the device; optional backup can use local files or WebDAV, while configured model providers receive prompts and attachments.

Jan
open sourceApache-2.0Local
44kaug 2026
A local-first desktop assistant with cloud connectors and tools; your RAM gets the invoice.
The catch vs Claude
The free local route usually gives up Claude's reasoning and long-document quality, while connecting Anthropic turns the replacement back into metered API spend.
Install, platforms & data +
platforms
desktopone-click install
install
Native macOS, Windows, or Linux desktop installer
setup
The first choice is consequential: local models need a sizable download and enough RAM, while cloud models require separately billed API keys.
engines
Runs local GGUF models through llama.cpp and Apple-silicon models through MLX, and connects to OpenAI, Anthropic, Google Gemini, Groq, Mistral, Azure, OpenRouter, Hugging Face, and custom OpenAI-compatible APIs.
your data
Models, assistants, files, and settings stay in Jan's data folder; threads are stored as local JSON and JSONL files. Cloud providers receive only the conversations or files routed to them.

LibreChat
open sourceMITSelf-host
42kaug 2026
A self-hosted model switchboard with agents, files and tools; free software, paid model bills if you use paid models.
The catch vs Claude
LibreChat can call Anthropic but does not include it, and it replaces Claude's managed service with a MongoDB-based system the user must secure and maintain.
Install, platforms & data +
platforms
webself-hosteddocker to self-host
install
Official Docker Compose stack
setup
It needs Docker, environment secrets, provider keys, storage, backups, and an admin; the official guide also documents a MongoDB image override because the default image crashes on Apple-silicon Macs.
engines
Connects to OpenAI, Anthropic, Google and Vertex AI, Azure OpenAI, AWS Bedrock, Mistral, Groq, custom OpenAI-compatible endpoints, and local backends exposed through compatible APIs.
your data
The default stack stores conversations and accounts in MongoDB, search indexes in Meilisearch, and uploaded or RAG files in local volumes or configured object/vector storage; every configured model provider receives the requests routed to it.

Big-AGI
open sourceMITLocal or hosted
7.1kaug 2026
A local-first multi-model workspace with files, search, code and personas; the interface assumes you enjoy buttons.
The catch vs Claude
Big-AGI offers a multi-model shell rather than Claude's included Anthropic models, first-party Projects and Artifacts workflow, and managed synchronization.
Install, platforms & data +
platforms
webself-hosteddocker to self-host
install
Use the hosted web app, or deploy the Next.js app yourself
setup
The first obstacle is bringing provider keys or a local endpoint; the app warns that browser-stored keys are plain text and protected only by the browser profile.
engines
Connects to more than twenty backends, including OpenAI, Anthropic, Google Gemini, OpenRouter, Azure OpenAI, AWS Bedrock, Groq, Mistral, DeepSeek, Ollama, LM Studio, LocalAI, and OpenAI-compatible endpoints.
your data
In the browser edition, provider keys and settings are stored in localStorage and chats, files, personas, and related workspace data in IndexedDB; configured model providers receive submitted content. There is no included cross-device cloud sync.

06
LM Studio
freeproprietary, freeLocal
A local-model desktop lab with chat, documents and tools; free forever, but your hardware is now the cloud.
The catch vs Claude
Local open-weight models usually fall short of Claude's strongest reasoning, writing, and long-document performance, and LM Studio lacks Claude's managed project workflow.
Install, platforms & data +
platforms
desktopone-click install
install
Native desktop installer or Linux AppImage
setup
The first obstacle is hardware: LM Studio recommends 16 GB RAM, requires current supported operating systems and CPU features, and useful models can occupy many gigabytes.
engines
Runs downloaded open-weight GGUF and safetensors models locally through llama.cpp and MLX-compatible runtimes, and exposes local OpenAI-compatible APIs.
your data
Downloaded models live in LM Studio's local model directory and chats are stored as local JSON conversation files; local inference does not send prompts to a model provider.

07
Open WebUI
freeOpen WebUI LicenseSelf-host
ChatGPT-shaped self-hosting with models, files, search and tools; the software is free, the admin role is yours.
The catch vs Claude
It can front Anthropic-compatible access but supplies neither Claude usage nor Anthropic's first-party Projects and Artifacts experience, while adding server administration.
Install, platforms & data +
platforms
desktopwebself-hostedone-click install
install
Docker is the recommended path; pip, uv, Kubernetes, and desktop-packaged paths are also documented
setup
The first obstacle is owning the service: Docker volumes, a model backend or API key, user security, updates, and backups; an unpersisted container loses the data.
engines
Connects natively to Ollama and OpenAI-compatible APIs, with documented support for providers and gateways such as OpenAI, Anthropic, Google, Azure, Groq, Mistral, OpenRouter, and local inference servers.
your data
A default single-node install persists accounts and chats in webui.db (SQLite), embeddings in Chroma, and uploads in the Open WebUI data volume; larger deployments can move these to PostgreSQL, Redis, and external vector or object stores.

08
LobeHub
freeLobeHub Community LicenseLocal or hosted
A polished agents-and-files workspace; self-hosting is free and frontier inference usually is not.
The catch vs Claude
Using Claude through LobeHub still requires separately billed Anthropic access, and self-hosted server mode is materially more complex than Claude's managed workspace.
Install, platforms & data +
platforms
webself-hostedone-click install
install
Hosted signup, one-click Vercel deployment, or Docker Compose for the server-database edition
setup
Hosted use still requires model credentials or purchased inference, while serious self-hosting adds PostgreSQL, object storage, authentication, secrets, a domain, and migration from browser-local data.
engines
Supports more than seventy providers and gateways, including OpenAI, Anthropic, Google Gemini, Azure OpenAI, AWS Bedrock, OpenRouter, Groq, DeepSeek, Ollama, LM Studio, and OpenAI-compatible endpoints.
your data
Local mode keeps chats in browser IndexedDB and supports JSON export; server mode uses PostgreSQL for account and conversation data plus S3-compatible object storage for files. Configured providers receive routed prompts and attachments.
