The Complete Local LLM Software Directory: 88 Tools to Run AI on Your Own Hardware (2026)

A runtime is the engine that loads model weights into memory and turns prompts into tokens. It is the first decision in a local-LLM stack and the one that constrains everything above it — every desktop app, web UI, and coding harness ultimately calls a runtime. Ollama dominates user-facing share in 2026 because it ships an OpenAI-compatible API and a one-command install; llama.cpp is the C++ engine underneath most of the others; vLLM is the right pick when you need to serve concurrent users on a real GPU.

Desktop apps wrap a runtime in a chat interface and a model browser. They are where most non-technical users start because there is no terminal step — download, click, chat. LM Studio, Jan, and GPT4All hold the bulk of the user base in 2026; AnythingLLM doubles as a desktop app and a RAG layer; Open Interpreter is the outlier that lets a local model drive your computer.

Web UIs are self-hosted ChatGPT clones — same conversational surface, but you point them at a runtime running on your own machine or LAN. They are the natural choice when you want multi-device access (laptop, phone, tablet hitting one server) or team usage. Open WebUI dominates the self-hosted segment in 2026, with LibreChat as the team-features alternative and SillyTavern as the dedicated roleplay UI.

Coding assistants connect a local LLM to your editor or terminal via OpenAI-compatible APIs. The choice is mostly about workflow primitive: autocomplete-in-editor (Continue.dev), autonomous agent edits (Cline, OpenHands), or git-native diff edits at the terminal (Aider). All three patterns work against any runtime that speaks the OpenAI Chat Completions protocol — Ollama is the most common backend in 2026.

RAG (Retrieval-Augmented Generation) systems combine a local LLM with an embedding model and a vector store so the model can answer from your own documents.** The split is between turn-key apps (AnythingLLM, PrivateGPT, Quivr, Khoj) that "just work" and framework libraries (LlamaIndex, Haystack, txtai) that you build on. RAGFlow has gained share in 2026 specifically for documents that need citation-grade retrieval.

Agent frameworks turn one-shot LLM calls into multi-step workflows — plan, act, observe, repeat. LangChain remains the general-purpose default; CrewAI and AutoGen specialise in role-based multi-agent setups; LangGraph is the right pick when state management matters across long-running flows. All eight frameworks below run cleanly against a local Ollama backend.

Voice and multimodal stacks extend a local LLM beyond text — speech in (STT), speech out (TTS), and vision. Whisper.cpp and faster-whisper own the local STT layer; Piper and Coqui share the TTS layer with XTTS v2 dominating voice cloning; LLaVA and Ollama vision models cover the vision side. A fully-offline voice assistant is buildable from this layer plus a small chat model.

Mobile clients run a quantised model directly on the phone using Apple Neural Engine, Qualcomm NPU, or pure CPU inference. The MLC LLM project is the foundational layer; consumer apps (PocketPal AI, Private LLM, LLM Farm, Layla) wrap it with a chat UI. Flagship phones in 2026 run 2-4B models at usable speeds (8-15 tokens/sec); 7B is on the edge of feasibility for top-tier hardware.

Specialized tools embed local LLMs into apps you already use — note-taking platforms (Obsidian, Logseq, Joplin), autonomous task agents (AutoGPT, BabyAGI, MetaGPT), and roleplay frontends (Agnai, RisuAI). These are not generic chat surfaces; they are workflow-specific integrations that assume you already have a host app and a runtime.

For readers who do not want to read nine categories, pick the closest stack and copy it. Each row pairs a real goal with a tested combination and the hardware floor it actually runs on.

This directory is reviewed every six months and patched between reviews — last updated July 2026, next scheduled refresh November 2026. The most recent pass reverified every link and corrected several project names and licences: Faraday is now Backyard AI, the maintained Coqui TTS fork moved to Idiap, and Cherry Studio is AGPL 3.0. Inclusion criteria: project is actively maintained (commits in the last 90 days), has a verifiable open-source licence or a clear commercial-use statement, and either holds meaningful user share in 2026 or fills a layer that would otherwise be empty. Projects that go inactive for more than two release cycles are removed; new entrants that pass the criteria are added at the next review. To suggest a project for inclusion, open an issue or PR against the PromptQuorum repository — include the project URL, licence, and a one-sentence description in the format above.
