qdrant-lens 0.1.8

A knowledge browser and audit layer for Qdrant vector databases

qdrant-lens

A knowledge browser for Qdrant vector databases.

Qdrant's own dashboard is a point browser — it shows raw vectors and payloads. qdrant-lens is the layer above that: it shows developers what the team has actually ingested, organised the way a human thinks about it.

• Knowledge tree — browse ingested content by source → document type → document → chunk, not by vector ID
• Accountability layer — every upsert and delete is intercepted, signed with the actor identity and timestamp, and written to an append-only audit log; raw Qdrant has no concept of who wrote a point or why — qdrant-lens ensures nothing in the cluster changes without a trace
• _lens schema enforcement — every point carries a validated metadata namespace; violations are surfaced before bad data reaches the index
• Sync-aware pipeline — chunk-hash dedup means re-ingesting a folder only embeds what actually changed; a scroll-diff pattern keeps Qdrant in sync with your filesystem the same way git tracks your working tree
• Structural graph layer — document relationships (same source, shared tags, same author) derived purely from payload fields, no Neo4j required
• Parser-agnostic ingest — LiteParse (default) handles PDFs, Office docs, images, and Jupyter notebooks natively; falls back to a pdfplumber/pytesseract stack automatically if needed
• Chat agent — ask questions about a collection in plain English, get answers backed by live tree/history/search tools; destructive operations require explicit typed confirmation before executing
• Export & migrate — dump any collection to portable JSONL/JSON (vectors + metadata) with lens export; ready-made recipes for Pinecone, Weaviate, Chroma, and OpenSearch

Prerequisites

Requirement	Version	Notes
Python	>= 3.12
Qdrant	>= 1.18.0	Self-hosted, Docker, or Qdrant Cloud
Docker	any	For docker compose up (optional). Docker Hub login required for image pulls — run docker login first, or download the Qdrant binary from github.com/qdrant/qdrant/releases
Tesseract	any	OCR only — sudo apt install tesseract-ocr / brew install tesseract. Set TESSDATA_PREFIX to your tessdata dir (e.g. /opt/homebrew/share/tessdata) if OCR fails at runtime
LibreOffice	any	Office → PDF conversion (bundled in [ingest])
Neo4j	>= 6.0	Graph RAG only — docker compose --profile graph up

---

Install

# Core: client wrapper + dashboard API only
pip install qdrant-lens

# + full ingestion pipeline (PDF parsing, OCR, chunking) — includes LiteParse by default
pip install "qdrant-lens[ingest]"

# + FastEmbed for CLI embeddings and sparse vectors (bm25_enable=True)
pip install "qdrant-lens[embed]"

# Everything
pip install "qdrant-lens[all]"

See docs/quickstart.md for uv, Docker, and .env setup.

Quickstart

Day 1 — 5 minutes, zero code changes

pip install qdrant-lens
lens serve --url http://localhost:6333
# Dashboard opens at http://localhost:7367
# Tree renders from your existing collection immediately

Day 2 — two line changes, audit log starts

from qdrant_lens import QdrantLensClient

# Drop-in replacement for QdrantClient — all existing calls unchanged
client = QdrantLensClient(url="http://localhost:6333", api_key="...")

# All upsert/delete calls now validate _lens metadata and write audit events
client.upsert(collection_name="docs", points=[...])

# New lens-only methods
doc_id = client.make_doc_id("github", "repo/auth/login.py")
tree   = client.tree("docs")
events = client.history("docs", last_n=20)
violations = client.validate("docs")

Async

from qdrant_lens import AsyncQdrantLensClient

client = AsyncQdrantLensClient(url="...", api_key="...")
tree = await client.tree("docs")

---

See docs/client.md for the full API reference and docs/ingest.md for the ingest pipeline.

---

Compatibility

• qdrant-client >= 1.18.0 required. Earlier versions are not supported.
• Python >= 3.12 (3.10 and 3.11 may work but are untested).

See COMPATIBILITY.md for the full version matrix and system dependency notes.

Built with

qdrant-lens stands on the shoulders of several excellent open-source projects:

Project	Role
Chonkie	Chunking backbone — token-aware RecursiveChunker, SemanticChunker, and CodeChunker strategies
PdfItDown	Office and image → PDF conversion in the auto parser stack (.docx, .pptx, .xlsx, .png, .jpg)
LiteParse	Default parser — single-library extraction for PDFs, Office docs, images, and more without a LibreOffice dependency
