Comparison
Conduit vs LM Studio
We make one of these, so read it the way you would read any vendor comparison. Like our page on Ollama, this one is unusual: LM Studio is the engine and the chat app in one download, Conduit is a client that can sit on top of it, and plenty of people run both. LM Studio details below were checked against LM Studio's own site and documentation on 24 September 2026 — if something has changed since, their sources are right and this page is wrong.
The short answer
Use LM Studio on its own if all you want is to find, download, and talk to a local open-weight model — it discovers and pulls models from Hugging Face, lets you tune how much of a model sits on the GPU versus system RAM, and gives you a chat window with none of that to configure. It is one app, one team, one install, and for that job it does not need anything sitting in front of it.
Add Conduit on top when you also want cloud models in the same window as your local ones, MCP tools with per-tool consent gating, retrieval over a broader set of your own file types, or a client you could eventually ship under your own brand. Conduit does not run models — it still needs LM Studio, Ollama, or a hosted provider behind it.
Side by side
| LM Studio | Conduit | |
|---|---|---|
| What it is | A model runner and chat app in one download | A client. Needs LM Studio, Ollama, or another provider behind it |
| Runs model weights | Yes — llama.cpp and, on Apple Silicon, MLX | No — it calls whichever provider's API you point it at |
| Find and download models | Yes — built-in search over Hugging Face | No. It lists what a connected provider already has |
| Hardware/GPU tuning | Yes — per-layer GPU offload, multi-GPU priority, RAM/VRAM split | Not applicable — nothing runs locally to tune |
| Local server for other apps | Yes — OpenAI- and Anthropic-compatible endpoints on localhost, plus a headless daemon (llmster) for running with no GUI at all |
Connects to one as a client; does not expose its own server |
| Other providers reachable | Its own local server only — not a multi-provider client | 17 built in — LM Studio and Ollama locally, 15 hosted ones with your own keys, side by side |
| MCP support | Yes, since v0.3.17 — local and remote servers via mcp.json |
Local stdio and remote streamable HTTP with OAuth, per-tool consent, and search/install from the official MCP registry |
| Chat with your own documents | Yes — attach .docx/.pdf/.txt; short files go in whole, longer ones use RAG; processing stays on the machine | Documents collections — text, Markdown, CSV, Word, PDF — with hybrid vector + full-text search; embedding needs a provider (Ollama keeps it local) |
| Licence | Proprietary freeware — free for personal and work use, source not published | AGPL-3.0 — source published, free including resale |
| Platforms | Windows, macOS, Linux | Windows 10/11, macOS 11+ (Universal), Linux (.deb and AppImage) |
| Rebrandable | No | Runtime branding today; packaging/OEM builds are early access from source |
| Paid tier | None for this app. The separate Bionic app has an Enterprise tier — cloud, on-prem, or edge deployment, contact sales for price | None. Free and open source; you pay your model provider directly |
Where LM Studio is better
It finds and manages the models, and we don't. Conduit has no model catalogue of its own. LM Studio's Discover tab searches Hugging Face, downloads a model, and lets you delete or swap it in a couple of clicks — all inside the same app you chat in.
Hardware tuning is a first-class feature, not an afterthought. How many layers sit on the GPU, whether a second GPU takes priority, whether the full model stays resident in system RAM after loading — these are real settings in LM Studio's UI. Conduit has no equivalent, because it never loads a model into memory itself.
It is one install, versioned together. The runtime, the server, the model manager, and the chat window ship as a single product from a single team. Nothing to point at a base URL, nothing to keep updated separately, one place to report a bug.
Its own local server already speaks two dialects. LM Studio's server exposes both OpenAI-compatible and Anthropic-compatible endpoints on localhost — useful if something else you run expects either shape without a translation layer.
Where a separate client adds something
Local and cloud models in one window. LM Studio's own server only ever serves the models it is running. Conduit ships 17 providers built in — LM Studio and Ollama for local models, 15 hosted providers reached with your own key — so a small local model and a frontier hosted one sit in the same conversation list rather than different apps.
MCP with consent gating built around it. LM Studio added MCP hosting in version 0.3.17 and its own docs are frank that some servers can run arbitrary code — the guidance is to only add ones you trust. Conduit's MCP connectors run as supervised child processes with per-tool consent prompts (auto for tools marked read-only, a prompt for every other one), output redaction, and a guard against prompt injection from tool output, plus remote MCP over streamable HTTP with OAuth and registry search built in.
Document retrieval across more file types. LM Studio's own document chat covers Word, PDF, and plain text, processed locally with retrieval-augmented generation for longer files — its current docs don't state a specific file-count or size cap. Conduit's Documents collections add Markdown and CSV on top, index everything with hybrid vector and keyword search, and a reply names the passage it drew on. The trade-off runs the other way on privacy: Conduit's indexing sends full document text to whichever provider does the embedding — OpenAI, Gemini, OpenRouter, or Ollama — and only Ollama keeps that step on the machine, the same as LM Studio's own document chat.
Open source, all the way down. LM Studio's own terms call its source code a trade secret and forbid reselling it as a service. Conduit ships under AGPL-3.0 with the source public, which is also why a rebranded build is possible at all without a licence to negotiate first. That freedom carries its own obligation, though: distributing a modified, rebranded build carries a duty to make the corresponding source available to whoever receives it — the white-label FAQ covers what that means in practice.
A client, not just a runner. Full-text search across every past conversation, fork a conversation at any point, edit-and-resend, artifacts for code and documents, a saved prompt library — the things a chat client accumulates once the model underneath it stops being the whole product.
The 2026 shift toward agents
LM Studio's own marketing homepage now leads with a different product: LM Studio Bionic, described in its docs as "the next generation of LM Studio designed for agentic work with open models" — its own agent for coding, research, and document-heavy tasks, with a companion Enterprise tier pitched at cloud, on-premises, or edge deployment through a sales conversation rather than a public price. LM Studio's own documentation is direct that this is a second, separate download, not a new mode inside the existing app: "Bionic is a new, separate app from LM Studio. For advanced low-level configuration, you can continue to use LM Studio alongside Bionic." The model runner, local server, MCP host, and document RAG covered on this page are all still part of that existing app, documented separately from Bionic and, on the evidence checked here, still actively maintained. If your interest is a local chat client rather than an agent product, that existing app — not the homepage's current headline — is what this comparison is against.
What Conduit does not do
- Run models — no inference of its own, no bundled runtime. Without LM Studio, Ollama, or a hosted provider it does nothing
- Find or download models — no catalogue, no Hugging Face search
- Tune hardware use — GPU offload, VRAM limits, and similar settings live in LM Studio, not Conduit
- Publish its source as a trade secret — the reverse: AGPL-3.0, source public
Which should you use?
If a local model is the whole project — find one, download it, tune it for your GPU, chat — LM Studio on its own is the better daily driver, and adding a second app would be pure overhead. Reach for Conduit once the client itself starts mattering: MCP tools with real consent handling, a hosted model alongside your local one in the same window, retrieval over a bigger set of your own files, or a client you might one day ship under your own name. Plenty of people end up with both installed — LM Studio managing and serving the local model, Conduit as the window that also reaches everything else.
Running local models generally? Conduit vs Ollama's own app covers the same question from the other local-model engine. Comparing clients more broadly, Best MCP clients, compared lines up the desktop, self-hosted, and IDE-shaped options, and the white-label page covers shipping a rebranded client under your own name.

Questions
Does LM Studio support MCP?
Yes. LM Studio has worked as an MCP host since version 0.3.17, connecting both local and remote MCP servers so a model can call their tools. Servers are added by editing the app's mcp.json file — the same notation used elsewhere — or with a one-click "Add to LM Studio" deeplink some MCP servers publish. Its own docs warn plainly that some servers can run arbitrary code or read local files, so only add ones you trust.
Do I still need LM Studio if I use Conduit?
Yes, for local models. Conduit does not run model weights of its own — it connects to LM Studio's local server the same way it connects to any provider, over the OpenAI-compatible API LM Studio exposes on your machine. LM Studio stays installed and stays the thing downloading and serving the model; Conduit replaces the chat window in front of it.
Is LM Studio free, and is it open source?
Free, not open source. LM Studio has been free for personal and internal business or workplace use since July 2025 — no separate commercial licence or form required any more. Its own terms describe the app as proprietary, calling its source code a trade secret, and prohibit reselling it as a hosted service. A separate LM Studio Enterprise tier exists for cloud, on-premises, or edge deployment, priced by talking to sales. Conduit's licence is the opposite shape: AGPL-3.0, source published, free for everyone including resale, no separate paid tier.
Can LM Studio chat with my own documents?
Yes. LM Studio lets you attach document files — .docx, .pdf, and .txt — to a chat. Short documents are added to the conversation in full; longer ones use retrieval-augmented generation to surface the relevant passages. Its offline-operation docs say that processing happens on your machine and nothing uploaded this way leaves the app. Its document-chat docs do not currently state a specific file-count or size limit, so we are not repeating a number here.
What is LM Studio Bionic, and does it change any of this?
It is a second, separate app. In 2026 LM Studio's own marketing homepage began leading with Bionic, described in LM Studio's docs as "the next generation of LM Studio designed for agentic work with open models" — its own agent for coding, research, and document-heavy tasks, with a paid Enterprise tier for cloud or on-prem deployment. LM Studio's own documentation is explicit that Bionic is a separate download, not a mode of the existing app: "you can continue to use LM Studio alongside Bionic." Everything on this page is about that existing app — the model runner, server, and MCP host most people mean by "LM Studio" — not Bionic.
