GPT4All vs Jan
Updated Jul 30, 2026 · pricing verified for both tools
GPT4All and Jan are both $0 and run fully offline, but Jan ships far more actively — v0.8.3 landed in June 2026 while GPT4All's latest stable build dates to early 2025. Jan adds a CLI, MCP support, and optional connections to 8 cloud providers at their own rates, but drops Intel Macs entirely. GPT4All still covers Intel Macs, Windows on ARM, and Linux with a one-click installer and LocalDocs RAG. Pick GPT4All for the widest hardware coverage; pick Jan for current development and a scriptable local API server.

Side by side
| Dimension | GPT4All | Jan |
|---|---|---|
| Pricing | $0, MIT-licensed, no paid tier, no subscription, no account | $0, Apache-2.0, no paid tier; optional cloud providers are billed by the provider with no Jan markup |
| Free tier | The entire app is free — no usage cap, no seat cost, no sign-up | The entire app is free — no usage cap, no seat cost, no sign-up |
| Hardware support | ✓ macOS on Intel and Apple Silicon, Windows including ARM (Snapdragon) builds, and Linux | Apple Silicon on macOS 13.6+ only — Intel Macs are unsupported — plus Windows and Linux |
| Maintenance | Latest stable build is v3.10.0 from early 2025, so updates arrive infrequently | ✓ v0.8.3 released 24 June 2026 with commits landing through mid-July 2026, at roughly 43,600 GitHub stars |
| API access | Built-in OpenAI-compatible local server for reusing on-device inference from other tools | ✓ OpenAI-compatible local server on port 1337 with optional API-key auth, plus MCP server support |
| Cloud fallback | Local models only — no cloud provider connections | ✓ Optional connections to OpenAI, Anthropic, Google, Groq, Mistral, Azure, OpenRouter, and Hugging Face; keys go direct |
| Private document RAG | LocalDocs runs retrieval over folders of your own documents | Projects, assistants, and file upload ground answers in your own files |
| Platforms | Desktop app only | ✓ Desktop app plus a CLI whose launch command serves a model and pre-wires an external agent to it |

When to pick GPT4All
- Your hardware rules Jan out. GPT4All runs on Intel Macs, on Windows ARM devices including Snapdragon, and on Linux, while Jan requires Apple Silicon on macOS 13.6 or newer and supports no Intel Mac at all.
- You want the simplest possible install for a non-technical user: a one-click installer that downloads and runs quantized open-weight models, with per-model download management and no account.
- Private document search is the main job. LocalDocs points at folders of your own files and answers from them entirely on-device, with nothing leaving the machine.
When to pick Jan
- You care that the project is alive. Jan shipped v0.8.3 on 24 June 2026 with commits continuing through mid-July, against a GPT4All stable build from early 2025 — on a fast-moving inference stack, that gap shows up in model support and speed.
- You want to script it. The Jan CLI serves a local model and pre-wires an external agent to it, the OpenAI-compatible server listens on port 1337 with optional API-key auth, and MCP support connects it to other tooling.
- You want a fallback when local models are not good enough. Jan connects optionally to eight cloud providers with keys sent straight to the provider and no markup, so one app covers both offline and frontier use — GPT4All is local-only.
Bottom line
Both are genuinely free forever, genuinely offline, and genuinely open source, so cost is not a factor and privacy is a wash — neither logs prompts, and neither requires an account. Jan is the stronger default in 2026 on development pace, surface area, and flexibility: a CLI, an authenticated local server, MCP support, an in-house model family, and optional cloud routing when a 7B local model is not enough. GPT4All wins on reach and simplicity, and that is not a small thing — if your machine is an Intel Mac or a Snapdragon Windows laptop, Jan will not install, and GPT4All’s one-click setup plus LocalDocs is easier to hand to someone who does not want to think about inference engines. Both are constrained by the same physics: answer quality is capped by available RAM, roughly 3B models on 8GB and 7B on 16GB, well below frontier cloud models for hard reasoning or coding. Neither ships a mobile app.
