Try it (60 seconds)

Requires Docker. First image pull may take 5–10 minutes.

curl -fsSL https://raw.githubusercontent.com/Zizka-ai/ZizkaDB/main/scripts/quickstart-remote.sh | bash

You should see:

tool_call · lookup_order · ORD-8842
  └── llm_response · gpt-4o
        └── user_message · Why was my order delayed?

Run again anytime: pip install zizkadb-sdk && zizkadb demo

Self-host from a clone

git clone https://github.com/Zizka-ai/ZizkaDB.git && cd ZizkaDB
bash scripts/setup-local.sh

Why?

Every agent team asks: Why did it say that? Why did it call that tool?

1. Log agent steps with parent_id (each step links to the one that caused it).
2. Ask why — terminal: zizkadb why <event_id> or Python: (await db.why(event_id)).print()
3. See the chain — walk back to the user message, wrong tool, or bad context.

Dashboard (same chain): Activity → support-bot → click an event → Why? (causal) tab.

Voice agents (LiveKit)

pip install zizkadb-livekit

One LiveKit call → one Session in Activity (transcript only, no audio in ZizkaDB). Full guide: CONNECT.md → LiveKit · docs/integrations/livekit.md · example.

Managed cloud (Pro / Team) — optional

Same Why? feature — hosted at db.zizka.ai. No Docker to maintain.

The operator admin console, VPC deploy, and cloud-only marketing routes live in the private zizkadb-cloud repo — see docs/REPO_SPLIT.md.

More features — drift, time-travel, search, GDPR

Function	What it does
db.baseline()	Detect when agent behavior drifts vs past sessions
db.at()	Reconstruct what the agent knew at a timestamp
db.search()	Semantic search over agent history
db.context_for()	Inject relevant past events into prompts
db.forget()	GDPR erasure by metadata filter

FAQ

Do I need to clone this repo?
No — the curl quickstart downloads config + Docker images only.

Do I need an API key locally?
No — http://localhost:8000 uses a built-in dev key. Dashboard: localhost:3001/login.

How is this different from Langfuse / LangSmith?
They observe span trees. ZizkaDB audits with explicit parent_id chains and db.why() on your Postgres — self-host under AGPL, no trace billing.

Voice agents with LiveKit?
Install zizkadb-livekit — one pip command, connect to Docker with ZIZKADB_HOST=http://localhost:8000. See LiveKit guide.

zizkadb demo connection refused?
Start the stack: curl -fsSL …/quickstart-remote.sh | bash or bash scripts/setup-local.sh.
