Free & open source
Qdrant
Free alternative to: Pinecone
License: Apache-2.0
Free terms: The engine is free to self-host at any scale with no feature gating; Qdrant Cloud (managed) is a separate paid offering with a free trial tier.
What it does
Rust-based open-source vector database for low-latency similarity search at scale, with hybrid dense+sparse search, payload filtering, quantization, and sharding.
Heads-up: License confirmed Apache-2.0 on qdrant/qdrant — no post-2018 relicensing to SSPL/BSL (unlike some competitors). Cloud-only features are proprietary, the core engine is fully open.
Get it
The project lives with its maintainers — we don't distribute it and we can't provide support for it.
