- [Maple](https://leyline.ahensya.com/components/maple.md): Maple is a general observability platform for traces, logs, and metrics. It accepts OTLP data and uses ClickHouse-family storage and query paths. Its product surfaces include distributed traces, correlated logs, metrics and dashboards, service maps, error tracking, alerts, infrastructure context, browser session replay, CLI queries, and an MCP server.

- [memini](https://leyline.ahensya.com/components/memini.md): Self-hosted persistent memory service for MCP-capable agents. It stores and recalls memories in a tiered store using hybrid vector and keyword retrieval, ships as a single Go binary with SQLite or Postgres, and exposes REST, MCP, and an embedded admin UI.
- [turbopuffer](https://leyline.ahensya.com/components/turbopuffer.md): turbopuffer is a managed, commercial search engine from turbopuffer Inc. (Canadian, founded 2023). It is object-storage-first: Amazon S3 / Google Cloud Storage / Azure Blob is the source of truth; NVMe and memory are caches. It does approximate vector search (SPFresh), BM25 full-text, filters, and hybrid fusion.
- [VictoriaMetrics](https://leyline.ahensya.com/components/victoriametrics.md): VictoriaMetrics develops separate storage/query components for the three primary OpenTelemetry signals: - VictoriaMetrics for time-series metrics; - VictoriaLogs for logs; and - VictoriaTraces for traces. Its current documentation says each component accepts OpenTelemetry data natively and can sit behind instrumented applications or an OpenTelemetry Collector.
- [ASC CLI](https://leyline.ahensya.com/components/asc-cli.md): App Store Connect CLI (asc) — fast, JSON-first Go CLI for the App Store Connect API. Automates TestFlight, builds/uploads, submissions, signing, analytics, screenshots, subscriptions, Apple Ads, and related release workflows for iOS/macOS/tvOS/visionOS.
- [Local FAISS MCP Server](https://leyline.ahensya.com/components/local-faiss-mcp-server.md): Local FAISS vector store exposed as an MCP server for document ingestion, embeddings, persistent indexes, semantic search, optional re-ranking, and RAG-style retrieval with MCP prompts.
- [Lore](https://leyline.ahensya.com/components/lore.md): Open-source shared persistent memory for AI agents, backed by Notion. A Lore vault is a Notion page with Projects, Topics, Memories, Entities, and Facts databases so later sessions and people can reuse experiential knowledge, follow-up tasks, decision records, and procedures.

- [pgbot](https://leyline.ahensya.com/components/pgbot.md): pgbot is a read-only, findings-first PostgreSQL diagnostic written in Go. Official README: one static binary connects, reads Postgres's own statistics views, and prints a graded health report plus what changed since last time. No collector, no time-series store, no write privilege anywhere in the path.
- [PostgreSQL](https://leyline.ahensya.com/components/postgresql.md): Open source object-relational database system for persistent SQL storage, described as a reliable relational database with official documentation and community support.
