LanceDB is an open-source vector database that embeds directly inside your application and is built on the Lance columnar format for fast similarity search across large multimodal datasets. It's aimed at AI/ML developers and engineering teams building retrieval, RAG, and agent-memory systems who want low-latency, billion-scale vector search without running a separate managed service. Its main differentiator is the disk-based Lance format, which keeps storage costs down and enables random-access reads over huge multimodal (text, image, video) datasets rather than holding everything in memory.

GitLab is the complete DevSecOps platform delivering software faster and more efficiently. With source code management, CI/CD, security, and project management in a single application, GitLab is trusted by 30 million+ developers.
