The honest brief

Qdrant

Rust single-binary you can self-host, with payload filtering strong enough that teams pick it for metadata-heavy search.

  • Open source, written in Rust
  • Self-host or managed cloud
  • Strong payload/metadata filtering
  • Predictable latency at scale
  • More ops than fully-managed rivals
  • Smaller ecosystem than Pinecone
  • Advanced features lean on managed cloud

TopK

One query spans vector, keyword, and multi-vector search with custom ranking — no separate search + vector + reranker stack to stitch together.

  • Serverless, no infra to manage
  • Runs in your own VPC (BYOC)
  • Built-in embedding/OCR inference
  • Low latency at billion-doc scale
  • SDKs for Python, JS, Rust + MCP
  • Newer, smaller ecosystem than peers
  • No open-source self-host
  • Developer/API-first, no managed UI
  • Smaller community vs Pinecone/Qdrant
