🏆 The 9 Best Local AI Tools We Actually Run (2026)
We run local AI daily on our own RTX 4080 rig. These are the 9 tools that survived — LLM runtimes, image and video pipelines — plus the 5 we uninstalled and why.
Most "best local AI tools" lists are written by people who have never watched a model load into VRAM. We run this stuff daily — local video renders through ComfyUI on an RTX 4080, local LLMs for drafting and coding — so this list is short, opinionated, and limited to tools that survived real use on our own hardware. The best local AI tools in 2026 are Ollama, LM Studio, ComfyUI and llama.cpp, with the rest depending on what you're building.
By the numbers
- Ollama's monthly downloads grew from ~100K in Q1 2023 to ~52 million in Q1 2026 — a 520× increase (Local AI in 2026 report)
- Ollama has passed 170K+ GitHub stars and 2.5 billion cumulative model downloads (GitHub)
- Hugging Face's GGUF catalog — the format local runtimes eat — grew from ~200 models to ~135,000
- ~5GB of VRAM runs a 7B model at Q4; 24GB opens up the 30B class (see our GPU guide)
The 9 tools, ranked by what they're best at
1. Ollama — the default LLM runtime
One command (ollama run qwen3) pulls a quantized model and serves it behind an OpenAI-compatible local API. It's what we point scripts and editors at. Full setup and daily-driver config in our Ollama complete guide.
2. LM Studio — the desktop cockpit
A polished GUI for browsing, downloading and chatting with GGUF models, with GPU-offload sliders and a local server mode. The best on-ramp if terminals aren't your thing. See how it stacks up in Ollama vs LM Studio.
3. ComfyUI — the local image & video studio
Node-based pipelines for Stable Diffusion, Flux and video models like Wan. This is the tool we personally run hardest — our render rig executes ComfyUI workflows daily. Steal our starting points in the workflow library.
4. llama.cpp — the engine underneath
The C++ inference engine that powers most of the ecosystem (70K+ GitHub stars). You'll rarely call it directly, but when you need exotic quants or maximum control, you drop down to it — official repo.
5. Jan — the offline ChatGPT clone
Clean chat app, fully offline, open-source. We recommend it to non-technical friends who just want private chat.
6. GPT4All — the zero-friction starter
Installs like a normal app, chats in two minutes, no configuration. Less power than LM Studio, easier first step.
7. Open WebUI — the self-hosted front-end
A browser UI that sits on top of Ollama — multi-user, RAG support, chat history. What we'd deploy for a small team.
8. text-generation-webui — the tinkerer's lab
Every sampler, every loader, every experimental flag. Messier than the rest; unbeatable when you need a knob the others hide.
9. LocalAI — the drop-in API server
A self-hosted OpenAI API replacement covering text, audio and images. The pick when an existing app expects the OpenAI SDK.
The cut list
We uninstalled or skipped: Faraday/Backyard (fine, but Jan covers it), KoboldCpp (great for fiction, niche otherwise), vLLM (superb throughput, but it's server infrastructure — overkill on a desktop), AnythingLLM (Open WebUI won for us), and closed freeware runners that lag GGUF releases by weeks.
How we picked
Every tool here ran on our own rig — an RTX 4080 (16GB) that renders AI video through Wan 2.2 with the Triton/SageAttention/TeaCache speed stack. We judge on install friction, VRAM behavior at real quantizations, update cadence, and whether the tool survives a month of daily use. No vendor paid for placement; when a tool loses, it loses in print.

Frequently asked questions
▸What is the easiest way to run an LLM locally?
LM Studio if you want a point-and-click desktop app, Ollama if you're comfortable with one terminal command. Both are free and handle model downloads and quantization for you.
▸How much VRAM do I need for local AI?
Around 5GB runs a 7B model at Q4 quantization, ~10GB runs 14B, and 24GB opens up the 30B class. Our full breakdown is in the GPU buying guide.
▸Are local AI tools really free?
The software in this list is free and open-source or free to use. Your costs are hardware and electricity — no subscriptions, no per-token pricing.
▸Can I generate images and video locally, not just text?
Yes — ComfyUI runs Stable Diffusion, Flux and video models like Wan on your own GPU. We render AI video locally every day on a 16GB RTX 4080.

ComparisonsOllama vs LM Studio (2026): Same-Hardware Verdict
We run both on the same 16GB RTX 4080. Where Ollama's one-command workflow wins, where LM Studio's GUI and offload sliders win, and the setup where we keep both.
