Logs in, architecture map out.

LogDoc is an open-source (Apache 2.0) structured-log platform: a single Go binary on top of ClickHouse that turns your logs into a live map of your system.

• Architecture map from logs alone — services and their dependencies appear on a live map without agents or mandatory tracing; deploy markers, "what changed" reports and a self-maintaining service catalog (Backstage export included) come with it.
• MCP built in — AI agents investigate your system through the same interface you use: query_logs, get_topology, get_topology_diff, get_service_card.
• Everything speaks to it — HTTP JSON, OpenTelemetry, syslog, journald, Python stdlib logging, the v1 native protocol, and a gRPC plugin SDK for the rest.

git clone https://github.com/LogDoc-org/logdoc && cd logdoc
docker compose -f deploy/docker-compose.yml up -d --build

First log in under five minutes — getting started.
