Observability engine for AI coding agents. Custom columnar log store, MCP-native, self-hosted on a $4/mo VM. No dashboards — your AI assistant sees production.
Collector-free telemetry for Laravel: Prometheus metrics, OTLP traces and events. No C extension, no protobuf, no sidecar — metrics that actually work under FPM.

Self-hosted error-monitoring for Python pipelines: capture exceptions, deduplicate, diagnose root causes with LLMs, route alerts (Telegram/Slack/email/GitHub/S3), and auto-generate fix PRs — from a logging handler or one report() call.
Fast CLI for searching, tracing, and streaming logs across files, Docker containers, and remote hosts using request IDs, trace IDs, and key/value search.
A local meter that prices subscription-agent usage and caps API-key spend before the next dollar leaves. One binary, one local SQLite ledger, no cloud. MIT.
