AI research assistant you control. Run locally for privacy, use any LLM and build your own searchable knowledge base. You own your data and see exactly how it works.

Option 1: Docker Run (Linux)

# Step 1: Pull and run Ollama
docker run -d -p 11434:11434 --name ollama ollama/ollama
docker exec ollama ollama pull gpt-oss:20b

# Step 2: Pull and run SearXNG for optimal search results
docker run -d -p 8080:8080 --name searxng searxng/searxng

# Step 3: Pull and run Local Deep Research
docker run -d --network host \
  --name local-deep-research \
  --volume "deep-research:/data" \
  -e LDR_DATA_DIR=/data \
  localdeepresearch/local-deep-research

Mac / Windows / WSL2 users: --network host only works on native Linux. On Docker Desktop it silently fails to publish port 5000 and leaves localhost pointing at the LDR container itself (so it can't reach Ollama/SearXNG). Use Option 2 below, or see the Windows/WSL2 FAQ entry for a working docker run recipe.

Option 2: Docker Compose

CPU-only (all platforms):

curl -O https://raw.githubusercontent.com/LearningCircuit/local-deep-research/main/docker-compose.yml && docker compose up -d

With NVIDIA GPU (Linux):

curl -O https://raw.githubusercontent.com/LearningCircuit/local-deep-research/main/docker-compose.yml && \
curl -O https://raw.githubusercontent.com/LearningCircuit/local-deep-research/main/docker-compose.gpu.override.yml && \
docker compose -f docker-compose.yml -f docker-compose.gpu.override.yml up -d

Open http://localhost:5000 after ~30 seconds. For GPU setup, environment variables, and more, see the Docker Compose Guide.

Option 3: pip install

pip install local-deep-research
python -m local_deep_research.web.app   # starts the web UI on http://localhost:5000

You'll also need Ollama (or any OpenAI-compatible LLM endpoint) and SearXNG running — see the pip install guide for the full recipe. Works on Windows, macOS, and Linux. SQLCipher encryption is included via pre-built wheels — no compilation needed. PDF export on Windows requires Pango (setup guide). If you encounter issues with encryption, set export LDR_BOOTSTRAP_ALLOW_UNENCRYPTED=true to use standard SQLite instead.

Older CPU (x86-64)? LDR needs an AVX-capable CPU — Intel Sandy Bridge / AMD Bulldozer (2011) or newer. Several scientific Python dependencies (pandas, scikit-learn) ship wheels that crash with Illegal instruction on older CPUs. ARM64 (aarch64) is fully supported. Every release is smoke-tested against this floor, including AVX-without-AVX2 CPUs (#4480).

You ask a complex question. Local Deep Research (LDR):

• Does the research for you automatically
• Searches across web, academic papers, and your own documents
• Synthesizes everything into a report with proper citations

Choose the research strategy that fits: quick pipeline modes for fast facts, or fully agentic deep research for complex analysis and academic work.

LangGraph Agent Strategy — An autonomous agentic research mode where the LLM decides what to search, which specialized engines to use (arXiv, PubMed, Semantic Scholar, etc.), and when to synthesize. It adaptively switches between search engines based on what it finds and collects significantly more sources than pipeline-based strategies — this is the strategy behind the ~95% SimpleQA result above. Select langgraph-agent in Settings.

    S -.-> R

Every research session finds valuable sources. Download them directly into your encrypted library — academic papers from ArXiv, PubMed articles, web pages. LDR extracts text, indexes everything, and makes it searchable. Next time you research, ask questions across your own documents and the live web together. Your knowledge compounds over time.

    U2[User B] --> D2[(Encrypted DB)]

Your data stays yours. Each user gets their own isolated SQLCipher database encrypted with AES-256, with the key derived from your password. Your password is never stored — login works by attempting to decrypt your database, so the database files on their own are unusable to anyone who obtains them. Per-user LLM API keys live encrypted inside the same personal database rather than in a shared server-level store.

The Docker setup ships with cap_drop: ALL, no-new-privileges, and a non-root runtime, with the bundled Ollama and SearXNG images pinned by digest. Or run fully local with Ollama + SearXNG and nothing ever leaves your machine.

In-memory credentials: Like any application that uses secrets at runtime, credentials are held in process memory during active sessions — mitigated with session-scoped credential lifetimes and core dump exclusion. See the Security Policy for the full threat model.

Supply Chain Security: Docker images are signed with Cosign using GitHub's keyless OIDC flow, include SLSA provenance attestations, and ship with attested SPDX SBOMs. See Verifying images and SBOMs for the step-by-step verification commands.

Security Transparency: Scanner suppressions are documented with justifications in Security Alerts Assessment, Scorecard Compliance, Container CVE Suppressions, and SAST Rule Rationale. Some alerts (Dependabot, code scanning) can only be dismissed or are very difficult to suppress outside the GitHub Security tab, so the files above do not cover every dismissed finding.

Local Deep Research contains no telemetry, no analytics, and no tracking. We do not collect, transmit, or store any data about you or your usage. No analytics SDKs, no phone-home calls, no crash reporting, no external scripts. Usage metrics stay in your local encrypted database.

The only network calls LDR makes are ones you initiate: search queries (to engines you configure), LLM API calls (to your chosen provider), and notifications (only if you set up Apprise).

Since we don't collect any usage data, we rely on you to tell us what works, what's broken, and what you'd like to see next — bug reports, feature ideas, and even which features you love or never use all help us improve LDR.

LDR respects robots.txt and identifies itself honestly when fetching web pages — no stealth or anti-detection techniques. In rare cases this means a page that blocks automated access won't be fetched, which we consider the right trade-off.

Full Search Engines Guide →

from local_deep_research.api import LDRClient, quick_query

# Option 1: Simplest - one line research
summary = quick_query("username", "password", "What is quantum computing?")
print(summary)

# Option 2: Client for multiple operations
client = LDRClient()
client.login("username", "password")
result = client.quick_research("What are the latest advances in quantum computing?")
print(result["summary"])

The code example below shows the basic API structure - for working examples, see the link below

import requests
from bs4 import BeautifulSoup

# Create session and authenticate
session = requests.Session()
login_page = session.get("http://localhost:5000/auth/login")
soup = BeautifulSoup(login_page.text, "html.parser")
login_csrf = soup.find("input", {"name": "csrf_token"}).get("value")

# Login and get API CSRF token
session.post("http://localhost:5000/auth/login",
            data={"username": "user", "password": "pass", "csrf_token": login_csrf})
csrf = session.get("http://localhost:5000/auth/csrf-token").json()["csrf_token"]

# Make API request
response = session.post("http://localhost:5000/api/start_research",
                       json={"query": "Your research question"},
                       headers={"X-CSRF-Token": csrf})

🚀 Ready-to-use HTTP API Examples → examples/api_usage/http/

• ✅ Automatic user creation - works out of the box
• ✅ Complete authentication with CSRF handling
• ✅ Result retry logic - waits until research completes
• ✅ Progress monitoring and error handling

# Run benchmarks from CLI
python -m local_deep_research.benchmarks.cli.benchmark_commands simpleqa --examples 50

See the Command Line Tools guide for the full reference.

Connect LDR to your existing knowledge base. Unlike the HTTP client above, quick_summary() runs LDR in-process — no server needed — so you can pass it live Python objects such as LangChain retrievers:

from local_deep_research.api import quick_summary

# Use your existing LangChain retriever
result = quick_summary(
    query="What are our deployment procedures?",
    retrievers={"company_kb": your_retriever},
    search_tool="company_kb"
)

Works with: FAISS, Chroma, Pinecone, Weaviate, Elasticsearch, and any LangChain-compatible retriever.

Integration Guide →

LDR provides an MCP (Model Context Protocol) server that allows AI assistants like Claude Desktop and Claude Code to perform deep research. Full setup details in the MCP Server guide.

⚠️ Security Note: This MCP server is designed for local use only via STDIO transport (e.g., Claude Desktop). It has no built-in authentication or rate limiting. Do not expose over a network without implementing proper security controls. See the MCP Security Best Practices for network deployment requirements.

# Install with MCP extras
pip install "local-deep-research[mcp]"

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "local-deep-research": {
      "command": "ldr-mcp",
      "env": {
        "LDR_LLM_PROVIDER": "openai",
        "LDR_LLM_OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

Add to your .mcp.json (project-level) or ~/.claude/mcp.json (global):

{
  "mcpServers": {
    "local-deep-research": {
      "command": "ldr-mcp",
      "env": {
        "LDR_LLM_PROVIDER": "ollama",
        "LDR_LLM_OLLAMA_URL": "http://localhost:11434"
      }
    }
  }
}

Any LDR setting can be passed in env as an LDR_* variable — see the auto-generated Full Configuration Reference for the complete list.

The search tool lets you query specific search engines directly and get raw results (title, link, snippet) — no LLM processing, no cost, fast. This is especially useful for monitoring and subscriptions where you want to check for new content regularly without burning LLM tokens.

# Search arXiv for recent papers
search(query="transformer architecture improvements", engine="arxiv")

# Search PubMed for medical literature
search(query="CRISPR clinical trials 2024", engine="pubmed")

# Search Wikipedia for quick facts
search(query="quantum error correction", engine="wikipedia")

# Search GitHub for code and repositories
search(query="agentic research frameworks", engine="github")

# Use list_search_engines() to see all available engines

"Use quick_research to find information about quantum computing applications"
"Search arxiv for recent papers on diffusion models"
"Generate a detailed research report on renewable energy trends"

• Ollama — connect to its native API (default http://localhost:11434)
• LM Studio — connect to its OpenAI-compatible server (default http://localhost:1234/v1)
• llama.cpp — connect to llama-server's OpenAI-compatible endpoint (default http://localhost:8080/v1); start with llama-server -m <model.gguf>
• Common models: Llama, Mistral, Gemma, DeepSeek, Qwen
• LLM processing stays local (search queries still go to web). No API costs.

💡 Which local model should I pick? See the community benchmarks — community-submitted accuracy numbers across local and cloud models, so you can compare before downloading.

• OpenAI
• Anthropic Claude
• Google Gemini
• 100+ models via OpenRouter
• 100+ models via Requesty

• OpenAI-Compatible Endpoint — any service speaking the OpenAI chat-completions API (vLLM, llama.cpp, gateways)
• Anthropic-Compatible Endpoint — a self-hosted service speaking the Anthropic Messages API (/v1/messages); set llm.anthropic_endpoint.url

Model Setup →

• llm.model no longer has a default. Pre-1.6.3 installs auto-filled gemma3:12b (Ollama) when no model was configured, which silently downloaded a multi-GB binary. The field is now empty by default — pick a model in Settings → LLM, or research will fail loudly with a clear error.
• The auto and parallel meta search engines were removed. The default langgraph-agent strategy selects engines dynamically per query, which replaces them. Stored settings are migrated automatically (removed values become searxng); update any explicit search_tool="auto" API calls or LDR_SEARCH_TOOL=auto env overrides to a concrete engine such as searxng.
• The llamacpp provider now uses HTTP instead of in-process loading. If you previously set llm.llamacpp_model_path to a local .gguf file, that setting is no longer read. Instead, run llama-server -m <your-model.gguf> (it ships with every modern llama.cpp build) and the default llm.llamacpp.url of http://localhost:8080/v1 will pick it up. Optional API key support is available via llm.llamacpp.api_key if you put llama-server behind an auth proxy.
